政府债务或主权债务

https://en.wikipedia.org/wiki/Government_debt#:~:text=

一个国家的政府总债务（也称为公共债务或主权债务[1]）是政府部门的金融负债。[2]: 81 政府债务随时间的变化主要反映了由于过去政府赤字而产生的借款。[3] 当政府的支出超过收入时，就会出现赤字。[4][2]: 79–82 政府债务可能欠国内居民，也可能欠外国居民。 如果欠外国居民，则该金额包含在该国的外债中。[5]

2020 年，全球政府债务价值为 87.4 万亿美元，占国内生产总值 (GDP) 的 99%。[6] 政府债务占所有债务（包括企业和家庭债务）的近 40%，为 1960 年代以来的最高比例。[6]自 2007 年以来，政府债务的增加主要归因于大衰退期间的刺激措施和 COVID-19 衰退。[6]

政府发行债务的能力一直是国家形成和国家建设的核心。[7][8] 公共债务与民主的兴起、私人金融市场和现代经济增长息息相关。[7][8]

衡量政府债务

政府债务通常以一般政府部门的总债务来衡量，这种债务以债务工具的形式存在。[2]: 207 债务工具是一种金融债权，要求债务人在未来向债权人支付利息和/或本金。例子包括债务证券（如债券和票据）、贷款和政府雇员养老金债务。[2]: 207

国际比较通常侧重于广义政府债务，因为各国负责计划（例如医疗保健）的政府级别不同，广义政府包括中央、州、省、地区、地方政府和社会保障基金。[2]: 18, s2.58, s2.59 根据国际货币基金组织的《2014 年政府财政统计手册》（GFSM），公共公司（如以市场为基础提供商品或服务的邮局）的债务不包括在广义政府债务中，该手册描述了编制债务统计数据以确保国际可比性的推荐方法。[2]: 33, s2.127

广义政府部门的总债务是作为债务工具的总负债。另一种债务衡量标准是净债务，即总债务减去债务工具形式的金融资产。[2]: 208, s7.243 净债务估值并不总是可用的，因为一些政府资产可能难以估值，例如以优惠利率发放的贷款。[2]: 208–209, s7.246

债务可以按市场价值或名义价值衡量。作为一般规则，GFSM 表示债务应按市场价值进行估值，即资产可以兑换成现金的价值。[2]: 55, s3.107 但是，名义价值对于发行债务的政府很有用，因为它是债务人欠债权人的金额。[2]: 191, ft28 如果没有市场价值和名义价值，则使用面值（到期时要偿还的未折现本金金额）[2]: 56 。[2]: 208, s7.238

一个国家的一般政府债务与 GDP 之比是其债务负担的指标，因为 GDP 衡量的是经济体在一段时间内（通常是一年）生产的商品和服务的价值。此外，以 GDP 百分比衡量的债务有助于在不同规模的国家之间进行比较。经合组织将一般政府债务与 GDP 之比视为政府财政可持续性的关键指标。[3]

政府债务积累的原因
政府借款的一个重要原因是充当经济“减震器”。例如，赤字融资可用于在经济衰退期间维持政府服务，因为经济衰退期间税收收入下降，失业救济金等支出上升。[9] 为支付重大冲击事件的成本而产生的政府债务可能特别有益。这些事件包括

像第二次世界大战这样的大战争；

像 COVID-19 衰退这样的公共卫生紧急事件；或
像大衰退这样的严重经济衰退。[10]
在没有债务融资的情况下，当经济低迷期间收入下降时，政府将需要提高税收或削减支出，这将加剧负面事件。

虽然政府借款有时可能是可取的，但当社会各群体对政府支出存在分歧时，可能会出现“赤字偏见”。[11][12] 为了应对赤字偏见，许多国家都采用了平衡预算规则或对政府债务进行限制。例子包括瑞典的“债务锚”[9]；德国和瑞士的“债务刹车”；以及欧盟《稳定与增长公约》协议，将政府总债务维持在不超过 GDP 的 60% 的水平。[13][14]

历史基准

政府发行债务的能力

一直是国家形成和国家建设的核心。[7][8] 公共债务与民主的兴起、私人金融市场和现代经济增长息息相关。[7][8] 例如，在 17 和 18 世纪，英国建立了一个议会，其中包括债权人，作为更大联盟的一部分，国家必须获得债权人的授权才能借款或加税。这一制度提高了英国的借贷能力，因为贷款人更愿意持有一个拥有支持债务偿还的民主制度的国家的债务，而不是一个君主无法被迫偿还债务的国家的债务。[7][8]

随着公共债务逐渐被认为是一种安全且流动性强的投资，它可以用作私人贷款的抵押品。这在公共债务市场和私人金融市场的发展之间形成了互补性。[7]政府借款为公共产品（如城市基础设施）融资与现代经济增长息息相关。[7]: 6

书面记录表明，早在两千年前，希腊锡拉丘兹等城邦就向其公民借款，当时就存在公共借款。[7]: 10–16 但 1694 年英格兰银行的成立彻底改变了公共财政，并结束了 1672 年查理二世暂停支付账单的“国库大停付”等违约行为。从那时起，英国政府就再也没有拖欠债权人了。[15] 在接下来的几个世纪里，欧洲其他国家以及后来世界各地的其他国家都采用了类似的金融机构来管理政府债务。

1815 年，拿破仑战争结束时，英国政府债务达到了 GDP 的 200% 以上的峰值，[16] 接近 8.87 亿英镑。[17]这些债务在 90 年内通过维持初级预算盈余（即支付利息后收入大于支出）偿还。[10]

1900 年，总债务最多的国家是法国（1,086,215,525 英镑），其次是俄罗斯（656,000,000 英镑），然后是英国（628,978,782 英镑）；[17] 按人均计算，负债最多的国家是新西兰（每人 58 英镑 12 先令）、澳大利亚殖民地（52 英镑 13 先令）和葡萄牙（35 英镑）。[17]

2018 年，全球政府债务达到 66 万亿美元，约占全球 GDP 的 80%，[18] 到 2020 年，全球政府债务达到 87 万亿美元，占全球 GDP 的 99%。[6] 2020 年，新冠疫情导致公共债务飙升，尤其是在实施全面财政措施的发达经济体。[6]

政府债务的影响

政府债务积累可能导致利率上升，[9] 这可能会挤占私人投资，因为政府与私营企业争夺有限的投资资金。一些证据表明，政府债务占 GDP 比重超过 80% 的国家的增长率较低。[9][19] 世界银行集团的一份报告分析了 1980 年至 2008 年 100 个发达国家和发展中国家的债务水平，发现发达国家债务占 GDP 比重超过 77%（发展中国家为 64%），每超过阈值一个百分点，未来年经济增长率就会下降 0.017 个百分点（发展中国家为 0.02 个百分点）。[20][21]

过高的债务水平可能使政府更容易受到债务危机的影响，即一个国家无法偿还债务，也无法借入更多资金。[9]危机代价高昂，尤其是当债务危机与金融/银行危机相结合时，会导致整个经济去杠杆化。随着企业出售资产以偿还债务，资产价格下跌，这可能会导致收入进一步下降，进一步压低税收收入，并要求政府大幅削减政府服务。[22] 债务危机的例子包括 20 世纪 80 年代初的拉丁美洲债务危机和 2001 年的阿根廷债务危机。为了避免危机，政府可能希望保持“财政喘息空间”。历史经验表明，在需要时将政府债务水平翻一番的空间是一个大致的指导。[9]

政府债务是在支出超过收入时通过借贷积累起来的，因此政府债务通常会产生代际转移。这是因为政府在债务产生时对商品和服务的支出的受益者通常与未来负责偿还债务的个人不同。

关于政府债务的另一种观点，有时被称为李嘉图等价命题，即如果个人是利他主义者并将债务对后代的影响内化，那么政府债务就不会对经济产生影响。[23] 根据这一命题，虽然政府购买的数量会影响经济，但债务融资将产生与税收融资相同的影响，因为通过债务融资，个人将预期偿还债务所需的未来税收，从而增加其储蓄和遗赠，其数额相当于政府债务。这样的结果

例如，个人储蓄增加意味着私人消费会随着政府债务的增加而下降，因此利率不会上升，私人投资也不会被挤出。

风险
信用（违约）风险
主要文章：信用风险
从历史上看，政府拖欠债务的情况很多，包括 16 和 17 世纪的西班牙，它多次取消了政府债务；美国内战后未偿还债务的美利坚联盟国；以及 1917 年后的革命俄罗斯，它拒绝承担俄罗斯帝国外债的责任。[24]

如果政府债务以一个国家自己的法定货币发行，有时被认为是无风险的，因为债务和利息可以通过创造货币来偿还。[25][26] 然而，并非所有政府都发行自己的货币。例子包括地方政府，如市、省和州政府；以及欧元区国家。在希腊政府债务危机中，一个提议的解决方案是让希腊退出欧元区，重新发行德拉克马[27][28]（尽管这只能解决未来的债务发行问题，而大量现有债务将以外币计价）。[29]

如果地方政府的债务由地区或国家级政府明确或隐含地担保，则通常认为对贷方来说风险较小。当纽约市在 20 世纪 70 年代陷入破产状态时，纽约州和美国联邦政府提供了救助。美国州和地方政府的债务规模巨大——2016 年，他们的债务总额达到 3 万亿美元，另有 5 万亿美元的未偿债务。[30]

通胀风险
发行本国货币的国家可能面临较低的本币违约风险，但如果中央银行通过购买政府债券（有时称为债务货币化）提供融资，则可能导致价格通胀。一个极端的例子是，20 世纪 20 年代，魏玛德国政府利用货币发行来偿还第一次世界大战后的国债，导致该国出现恶性通货膨胀。

汇率风险
虽然以美元计价的美国国债对美国买家来说可能被视为无风险，但外国投资者却要承担美元相对于本国货币贬值的风险。政府可以发行外币债务，以消除外国贷款人的汇率风险，但这意味着借款政府要承担汇率风险。此外，通过发行外币债务，一个国家不能通过通货膨胀来侵蚀债务价值。[31] 从 1979 年到 2006 年，发展中国家样本中几乎 70% 的债务都是以美元计价的。[32]

隐性负债和或有负债

大多数政府都有或有负债，即除非未来发生特定事件，否则不会产生的义务。[2]: 76 显性或有负债的一个例子是公共部门贷款担保，政府只有在债务人违约时才需要付款。[2]: 210, s.7.252 隐性或有负债的例子包括确保支付未来的社会保障养老金福利、在违约的情况下承担地方政府的义务以及用于自然灾害救助的支出。[2]: 209–210

显性或有负债和净隐性社会保障义务应作为备忘项目列入政府资产负债表，[2]: 69, 76–77, 209–212 但它们不包括在政府债务中，因为它们不是合同义务。[2]: 210, s.7.252 事实上，政府改变债务状况并不罕见例如，单方面改变社会保障计划的福利结构（例如，通过改变福利支付的情况或福利金额）。[2]： 76， s4.49 在美国和许多国家，没有专门用于未来社会保险支付的资金——这种制度被称为现收现付制。根据美国社会保障和医疗保险信托基金受托人的 2018 年年度报告，医疗保险在未来 75 年内面临 37 万亿美元的未付负债，而社会保障在同一时期内面临 13 万亿美元的未付负债。[33] 这两个金额都不包括在美国政府总债务中，2024 年的债务为 34 万亿美元。[34]

2010 年，欧盟委员会要求欧盟成员国以标准化方法公布其债务信息，明确包括之前以多种方式隐藏的债务，以满足地方（国家）和欧洲（稳定与增长公约）层面的最低要求。[35]

Government debt or sovereign debt

https://en.wikipedia.org/wiki/Government_debt#:~:text=

A country's gross government debt (also called public debt or sovereign debt[1]) is the financial liabilities of the government sector.[2]: 81 Changes in government debt over time reflect primarily borrowing due to past government deficits.[3] A deficit occurs when a government's expenditures exceed revenues.[4][2]: 79–82 Government debt may be owed to domestic residents, as well as to foreign residents. If owed to foreign residents, that quantity is included in the country's external debt.[5]

In 2020, the value of government debt worldwide was $87.4 US trillion, or 99% measured as a share of gross domestic product (GDP).[6] Government debt accounted for almost 40% of all debt (which includes corporate and household debt), the highest share since the 1960s.[6] The rise in government debt since 2007 is largely attributable to stimulus measures during the Great Recession, and the COVID-19 recession.[6]

The ability of government to issue debt has been central to state formation and to state building.[7][8] Public debt has been linked to the rise of democracy, private financial markets, and modern economic growth.[7][8]

Measuring government debt

Government debt is typically measured as the gross debt of the general government sector that is in the form of liabilities that are debt instruments.[2]: 207 A debt instrument is a financial claim that requires payment of interest and/or principal by the debtor to the creditor in the future. Examples include debt securities (such as bonds and bills), loans, and government employee pension obligations.[2]: 207

International comparisons usually focus on general government debt because the level of government responsible for programs (for example, health care) differs across countries and the general government comprises central, state, provincial, regional, local governments, and social security funds.[2]: 18, s2.58, s2.59 The debt of public corporations (such as post offices that provide goods or services on a market basis) is not included in general government debt, following the International Monetary Fund's Government Finance Statistics Manual 2014 (GFSM), which describes recommended methodologies for compiling debt statistics to ensure international comparability.[2]: 33, s2.127

The gross debt of the general government sector is the total liabilities that are debt instruments. An alternative debt measure is net debt, which is gross debt minus financial assets in the form of debt instruments.[2]: 208, s7.243 Net debt estimates are not always available since some government assets may be difficult to value, such as loans made at concessional rates.[2]: 208–209, s7.246

Debt can be measured at market value or nominal value. As a general rule, the GFSM says debt should be valued at market value, the value at which the asset could be exchanged for cash.[2]: 55, s3.107 However, the nominal value is useful for a debt-issuing government, as it is the amount that the debtor owes to the creditor.[2]: 191, ft28 If market and nominal values are not available, face value (the undiscounted amount of principal to be repaid at maturity)[2]: 56 is used.[2]: 208, s7.238

A country's general government debt-to-GDP ratio is an indicator of its debt burden since GDP measures the value of goods and services produced by an economy during a period (usually a year). As well, debt measured as a percentage of GDP facilitates comparisons across countries of different size. The OECD views the general government debt-to-GDP ratio as a key indicator of the sustainability of government finance.[3]

Causes of government debt accumulation
An important reason governments borrow is to act as an economic "shock absorber". For example, deficit financing can be used to maintain government services during a recession when tax revenues fall and expenses rise for say unemployment benefits.[9] Government debt created to cover costs from major shock events can be particularly beneficial. Such events would include

a major war, like World War II;
a public health emergency like the COVID-19 recession; or
a severe economic downturn as with the Great Recession.[10]
In the absence of debt financing, when revenues decline during a downturn, a government would need to raise taxes or reduce spending, which would exacerbate the negative event.

While government borrowing may be desirable at times, a "deficits bias" can arise when there is disagreement among groups in society over government spending.[11][12] To counter deficit bias, many countries have adopted balanced budget rules or restrictions on government debt. Examples include the "debt anchor"[9] in Sweden; a "debt brake" in Germany and Switzerland; and the European Union's Stability and Growth Pact agreement to maintain a general government gross debt of no more than 60% of GDP.[13][14]

Historic benchmarks

The ability of government to issue debt has been central to state formation and to state building.[7][8] Public debt has been linked to the rise of democracy, private financial markets, and modern economic growth.[7][8] For example, in the 17th and 18th centuries England established a parliament that included creditors, as part of a larger coalition, whose authorization had to be secured for the country to borrow or raise taxes. This institution improved England's ability to borrow because lenders were more willing to hold the debt of a state with democratic institutions that would support debt repayment, versus a state where the monarch could not be compelled to repay debt.[7][8]

As public debt came to be recognized as a safe and liquid investment, it could be used as collateral for private loans. This created a complementarity between the development of public debt markets and private financial markets.[7] Government borrowing to finance public goods, such as urban infrastructure, has been associated with modern economic growth.[7]: 6

Written records point to public borrowing as long as two thousand years ago when Greek city-states such as Syracuse borrowed from their citizens.[7]: 10–16 But the founding of the Bank of England in 1694 revolutionised public finance and put an end to defaults such as the Great Stop of the Exchequer of 1672, when Charles II had suspended payments on his bills. From then on, the British Government would never fail to repay its creditors.[15] In the following centuries, other countries in Europe and later around the world adopted similar financial institutions to manage their government debt.

In 1815, at the end of the Napoleonic Wars, British government debt reached a peak of more than 200% of GDP,[16] nearly 887 million pounds sterling.[17] The debt was paid off over 90 years by running primary budget surpluses (that is, revenues were greater than spending after payment of interest).[10]

In 1900, the country with the most total debt was France (£1,086,215,525), followed by Russia (£656,000,000) then the United Kingdom (£628,978,782);[17] on a per-capita basis, the highest-debt countries were New Zealand (£58 12s. per person), the Australian colonies (£52 13s.) and Portugal (£35).[17]

In 2018, global government debt reached the equivalent of $66 trillion, or about 80% of global GDP,[18] and by 2020, global government debt reached $87US trillion, or 99% of global GDP.[6] The COVID-19 pandemic caused public debt to soar in 2020, particularly in advanced economies that put in place sweeping fiscal measures.[6]

Impacts of government debt

Government debt accumulation may lead to a rising interest rate,[9] which can crowd out private investment as governments compete with private firms for limited investment funds. Some evidence suggests growth rates are lower for countries with government debt greater than around 80 percent of GDP.[9][19] A World Bank Group report that analyzed debt levels of 100 developed and developing countries from 1980 to 2008 found that debt-to-GDP ratios above 77% for developed countries (64% for developing countries) reduced future annual economic growth by 0.017 (0.02 for developing countries) percentage points for each percentage point of debt above the threshold.[20][21]

Excessive debt levels may make governments more vulnerable to a debt crisis, where a country is unable to make payments on its debt, and it cannot borrow more.[9] Crises can be costly, particularly if a debt crisis is combined with a financial/banking crisis which leads to economy-wide deleveraging. As firms sell assets to pay off debt, asset prices fall which risks an even greater fall in incomes, further depressing tax revenue and requiring governments to drastically cut government services.[22] Examples of debt crises include the Latin American debt crisis of the early 1980s, and Argentina's debt crisis in 2001. To help avoid a crisis, governments may want to maintain a "fiscal breathing space". Historical experience shows that room to double the level of government debt when needed is an approximate guide.[9]

Government debt is built up by borrowing when expenditure exceeds revenue, so government debt generally creates an intergenerational transfer. This is because the beneficiaries of the government's expenditure on goods and services when the debt is created typically differ from the individuals responsible for repaying the debt in the future.

An alternative view of government debt, sometimes called the Ricardian equivalence proposition, is that government debt has no impact on the economy if individuals are altruistic and internalize the impact of the debt on future generations.[23] According to this proposition, while the quantity of government purchases affects the economy, debt financing will have the same impact as tax financing because with debt financing individuals will anticipate the future taxes needed to repay the debt, and so increase their saving and bequests by the amount of government debt. Such higher individual saving means, for example, that private consumption falls one-for-one with the rise in government debt, so the interest rate would not rise and private investment is not crowded out.

Risk
Credit (Default) risk
Main article: Credit risk
Historically, there have been many cases where governments have defaulted on their debts, including Spain in the 16th and 17th centuries, which nullified its government debt several times; the Confederate States of America, whose debt was not repaid after the American Civil War; and revolutionary Russia after 1917, which refused to accept responsibility for Imperial Russia's foreign debt.[24]

If government debt is issued in a country's own fiat money, it is sometimes considered risk free because the debt and interest can be repaid by money creation.[25][26] However, not all governments issue their own currency. Examples include sub-national governments, like municipal, provincial, and state governments; and countries in the eurozone. In the Greek government-debt crisis, one proposed solution was for Greece to leave the eurozone and go back to issuing the drachma[27][28] (although this would have addressed only future debt issuance, leaving substantial existing debt denominated in what would then be a foreign currency).[29]

Debt of a sub-national government is generally viewed as less risky for a lender if it is explicitly or implicitly guaranteed by a regional or national level of government. When New York City declined into what would have been bankrupt status during the 1970s, a bailout came from New York State and the United States national government. U.S. state and local government debt is substantial — in 2016 their debt amounted to $3 trillion, plus another $5 trillion in unfunded liabilities.[30]

Inflation risk
A country that issues its own currency may be at low risk of default in local currency, but if a central bank provides finance by buying government bonds (sometimes referred to as debt monetization), this can lead to price inflation. In an extreme case, in the 1920s Weimar Germany suffered from hyperinflation when the government used money creation to pay off the national debt following World War I.

Exchange rate risk
While U.S. Treasury bonds denominated in U.S. dollars may be considered risk-free to an American purchaser, a foreign investor bears the risk of a fall in the value of the U.S. dollar relative to their home currency. A government can issue debt in foreign currency to eliminate exchange rate risk for foreign lenders, but that means the borrowing government then bears the exchange rate risk. Also, by issuing debt in foreign currency, a country cannot erode the value of the debt by means of inflation.[31] Almost 70% of all debt in a sample of developing countries from 1979 through 2006 was denominated in U.S. dollars.[32]

Implicit and contingent liabilities
Most governments have contingent liabilities, which are obligations that do not arise unless a particular event occurs in the future.[2]: 76 An example of an explicit contingent liability is a public sector loan guarantee, where the government is required to make payments only if the debtor defaults.[2]: 210, s.7.252 Examples of implicit contingent liabilities include ensuring the payment of future social security pension benefits, covering the obligations of subnational governments in the event of a default, and spending for natural disaster relief.[2]: 209–210

Explicit contingent liabilities and net implicit social security obligations should be included as memorandum items to a government's balance sheet,[2]: 69, 76–77, 209–212 but they are not included in government debt because they are not contractual obligations.[2]: 210, s.7.252 Indeed, it is not uncommon for governments to change unilaterally the benefit structure of social security schemes, for example (e.g., by changing the circumstances under which the benefits become payable, or the amount of the benefit).[2]: 76, s4.49 In the U.S. and in many countries, there is no money earmarked for future social insurance payments — the system is called a pay-as-you-go scheme. According to the 2018 annual reports from the trustees for the U.S. Social Security and Medicare trust funds, Medicare is facing a $37 trillion unfunded liability over the next 75 years, and Social Security is facing a $13 trillion unfunded liability over the same time frame.[33] Neither of these amounts are included in the U.S. gross general government debt, which in 2024 was $34 trillion.[34]

In 2010 the European Commission required EU Member Countries to publish their debt information in standardized methodology, explicitly including debts that were previously hidden in a number of ways to satisfy minimum requirements on local (national) and European (Stability and Growth Pact) level.[35]

政府债券或主权债券

https://en.wikipedia.org/wiki/Government_bond

政府债券或主权债券是政府为支持公共支出而发行的一种债券。它通常包括承诺支付定期利息（称为息票支付）并在到期日偿还票面价值。

例如，债券持有人将 20,000 美元（称为票面价值或本金）投资于 10 年期政府债券，年息票率为 10%；政府每年将向债券持有人支付 10% 的利息（在本例中为 2000 美元），并在到期日（即 10 年后）偿还 20,000 美元的原始票面价值。

政府债券可以以外币或政府的本国货币计价。经济不太稳定的国家倾向于以经济更稳定的国家的货币（即硬通货）计价其债券。所有债券都存在违约风险；即政府无法偿还债券持有人的可能性。经济不稳定的国家的债券通常被认为风险较高。国际信用评级机构对每个国家的债券都进行评级。债券持有人通常要求风险较高的债券获得更高的收益率。例如，2016年5月24日，加拿大政府发行的10年期国债收益率为1.34%，而巴西政府发行的10年期国债收益率为12.84%。

接近违约的政府有时被称为主权债务危机。

历史
荷兰共和国于1517年借用阿姆斯特丹市发行的债券，成为第一个通过债券融资的国家。当时的平均利率在20%左右波动。

第一个由国家政府发行的官方政府债券是由英格兰银行于1694年发行的，旨在筹集资金资助对法战争。这些债券的形式既有彩票，也有年金。英格兰银行和政府债券是由英格兰国王威廉三世（也称为奥兰治的威廉）在英国引入的，他模仿荷兰七省发行债券和筹集政府债务的方式为英国的战争提供资金，他以荷兰七省总督的身份统治这些省份。

后来，欧洲各国政府开始追随这一趋势，发行永久债券（没有到期日的债券）来资助战争和其他政府支出。永久债券的使用在 20 世纪停止，目前各国政府发行的债券期限有限。

在美国独立战争期间，为了筹集资金，美国政府开始发行债券 - 称为贷款证书。债券产生的总金额为 2700 万美元，为战争提供了资金。[3]

风险
信用风险
严格来说，以一国本国货币发行的政府债券是一种无风险债券，因为政府可以在必要时创造额外的货币以在到期时赎回债券。对于大多数政府来说，这只能通过发行新债券来实现，因为政府没有创造货币的可能性。（在“量化宽松”过程中，中央银行用新创造的货币购买发行的债券，可以视为事实上的中央银行直接向国家提供融资，独立中央银行对此已正式禁止。）有些政府选择拖欠本币债务，而不是创造额外的货币，例如 1998 年的俄罗斯（“卢布危机”）（参见国家破产）。

投资者可以使用评级机构来评估信用风险。在美国，证券交易委员会 (SEC) 已指定十家评级机构作为国家认可的统计评级机构。

货币风险
货币风险是指债券支付的货币价值相对于持有人的参考货币下跌的风险。例如，德国投资者会认为美国债券比德国债券具有更大的货币风险（因为美元相对于欧元可能会下跌）；同样，美国投资者会认为德国债券比美国债券具有更大的货币风险（因为欧元兑美元可能会下跌）。以没有保值历史的货币支付的债券即使提供高利率也可能不划算。[4] 货币风险由汇率波动决定。

通货膨胀风险
通货膨胀风险是指债券支付的货币价值会随着时间的推移而下降的风险。投资者预计会有一定程度的通货膨胀，因此风险在于通货膨胀率会高于预期。许多政府发行通胀指数债券，通过将利息支付和到期支付与消费者价格指数挂钩来保护投资者免受通胀风险。在英国，这些债券被称为指数挂钩债券。在美国，这些债券被称为 I 系列债券。

利率风险

除市场风险外，所有债券都受利率风险影响。利率变化会影响债券的价值。如果利率下降，则债券价格上涨，如果利率上升，则债券价格下跌。当利率上升时，债券更具吸引力，因为投资者可以获得更高的票面利率，从而可能出现持有期风险。利率和债券价格呈负相关。较低的固定利率债券票面利率意味着较高的利率风险，较高的固定利率债券票面利率意味着较低的利率风险。债券的期限也会影响利率风险。事实上，期限越长，利率风险越高，期限越短，利率风险越低。

货币供应
另请参阅：量化宽松
如果中央银行购买政府证券，例如债券或国库券，则会增加货币供应量，因为中央银行会向经济注入流动性（现金）。这样做会降低政府债券的收益率。相反，当中央银行对抗通胀时，中央银行会减少货币供应量。

这些增加或减少银行系统中货币量的行为被称为货币政策。

在英国，政府债券被称为英国国债。较早发行的债券有“国库券”等名称，较新发行的债券则被称为“国库金债券”。[5][6] 通胀指数化国债被称为指数挂钩国债。[7] 这意味着国债的价值会随着通货膨胀而上升。它们是英国政府为筹集资金而发行的固定利率证券。[需要引证] 英国国债的发行由英国财政部执行机构英国债务管理办公室管理。1998 年 4 月之前，英国国债由英格兰银行发行。[8] 购买和销售服务由 Computershare 管理。[9]

英国国债的到期期限比其他欧洲政府债券更长，这影响了各个国家养老金和人寿保险市场的发展。

传统的英国政府债券可能看起来像这样——“国库券 3% 2020”。[10] 2019 年 4 月 27 日，英国 10 年期政府债券收益率为 1.145%。根据标准普尔的数据，中央银行利率为 0.10%，英国评级为 AA。[11]

美国

美国财政部提供了几种不同期限的债券。某些债券可能会支付利息，其他则不会。这些债券可能是：

储蓄债券：它们被认为是最安全的投资之一。
国库券 (T-notes)：这些债券的期限为两年、三年、五年或十年，每六个月提供固定的息票支付，面值为 1,000 美元。
国库券 (T-bonds 或长期债券)：是期限最长的国库券，从二十年到三十年不等。它们每六个月也会支付一次息票。
国库通胀保值债券 (TIPS)：是美国财政部发行的通胀指数债券。这些债券的本金根据消费者价格指数进行调整。换句话说，本金随通货膨胀而增加，随通货紧缩而减少。
投资者持有美国政府债券的主要理由是这些债券免征州税和地方税。

这些债券通过政府的拍卖系统出售。债券在二级市场上买卖，二级市场是交易股票、债券、期权和期货等金融工具的金融市场。

Government bond or sovereign bond

https://en.wikipedia.org/wiki/Government_bond

A government bond or sovereign bond is a form of bond issued by a government to support public spending. It generally includes a commitment to pay periodic interest, called coupon payments, and to repay the face value on the maturity date.

For example, a bondholder invests $20,000, called face value or principal, into a 10-year government bond with a 10% annual coupon; the government would pay the bondholder 10% interest ($2000 in this case) each year and repay the $20,000 original face value at the date of maturity (i.e. after 10 years).

Government bonds can be denominated in a foreign currency or the government's domestic currency. Countries with less stable economies tend to denominate their bonds in the currency of a country with a more stable economy (i.e. a hard currency). All bonds carry default risk; that is, the possibility that the government will be unable to pay bondholders. Bonds from countries with less stable economies are usually considered to be higher risk. International credit rating agencies provide ratings for each country's bonds. Bondholders generally demand higher yields from riskier bonds. For instance, on May 24, 2016, 10-year government bonds issued by the Canadian government offered a yield of 1.34%, while 10-year government bonds issued by the Brazilian government offered a yield of 12.84%.

Governments close to a default are sometimes referred to as being in a sovereign debt crisis.^[1][2]

The Dutch Republic became the first state to finance its debt through bonds when it assumed bonds issued by the city of Amsterdam in 1517. The average interest rate at that time fluctuated around 20%.

The first official government bond issued by a national government was issued by the Bank of England in 1694 to raise money to fund a war against France. The form of these bonds was both lottery and annuity. The Bank of England and government bonds were introduced in England by William III of England (also called William of Orange), who financed England's war efforts by copying the approach of issuing bonds and raising government debt from the Seven Dutch Provinces, where he ruled as a stadtholder.

Later, governments in Europe started following the trend and issuing perpetual bonds (bonds with no maturity date) to fund wars and other government spending. The use of perpetual bonds ceased in the 20th century, and currently governments issue bonds of limited term to maturity.

During the American Revolution, in order to raise money, the U.S. government started to issue bonds - called loan certificates. The total amount generated by bonds was $27 million and helped finance the war.^[3]

Risks

[edit]

Credit risk

[edit]

A government bond in a country's own currency is strictly speaking a risk-free bond, because the government can if necessary create additional currency in order to redeem the bond at maturity. For most governments, this is possible only through the issue of new bonds, as the governments have no possibility to create currency. (The issue of bonds which are then bought by the central bank with newly created currency in the process of "quantitative easing" may be regarded as de facto direct state financing from the central bank, which is outlawed officially for independent central banks.) There have been instances where a government has chosen to default on its domestic currency debt rather than create additional currency, such as Russia in 1998 (the "ruble crisis") (see national bankruptcy).

Investors may use rating agencies to assess credit risk. In the United States, the Securities and Exchange Commission (SEC) has designated ten rating agencies as nationally recognized statistical rating organizations.

Currency risk

[edit]

Currency risk is the risk that the value of the currency a bond pays out will decline compared to the holder's reference currency. For example, a German investor would consider United States bonds to have more currency risk than German bonds (since the dollar may go down relative to the euro); similarly, a United States investor would consider German bonds to have more currency risk than United States bonds (since the euro may go down relative to the dollar). A bond paying in a currency that does not have a history of keeping its value may not be a good deal even if a high interest rate is offered.^[4] The currency risk is determined by the fluctuation of exchange rates.

Inflation risk

Inflation risk is the risk that the value of the currency a bond pays out will decline over time. Investors expect some amount of inflation, so the risk is that the inflation rate will be higher than expected. Many governments issue inflation-indexed bonds, which protect investors against inflation risk by linking both interest payments and maturity payments to a consumer price index. In the UK these bonds are called Index-linked bonds. In the US these bonds are called Series I bonds.

Interest rate risk

Also referred to as market risk, all bonds are subject to interest rate risk. Interest rate changes can affect the value of a bond. If the interest rates fall, then the bond prices rise and if the interest rates rise, bond prices fall. When interest rates rise, bonds are more attractive because investors can earn higher coupon rate, thereby holding period risk may occur. Interest rate and bond price have negative correlation. Lower fixed-rate bond coupon rates meaning higher interest rate risk and higher fixed-rate bond coupon rates meaning lower interest rate risk. Maturity of a bond also has an impact on the interest rate risk. Indeed, longer maturity meaning higher interest rate risk and shorter maturity meaning lower interest rate risk.

Money supply

[edit]

See also: Quantitative easing

If a central bank purchases a government security, such as a bond or treasury bill, it increases the money supply because a Central Bank injects liquidity (cash) into the economy. Doing this lowers the government bond's yield. On the contrary, when a Central Bank is fighting against inflation then a Central Bank decreases the money supply.

These actions of increasing or decreasing the amount of money in the banking system are called monetary policy.

United Kingdom

[edit]

In the UK, government bonds are called gilts. Older issues have names such as "Treasury Stock" and newer issues are called "Treasury Gilt".^[5][6] Inflation-indexed gilts are called Index-linked gilts.,^[7] which means the value of the gilt rises with inflation. They are fixed-interest securities issued by the British government in order to raise money.^{[citation needed]} The issuance of gilts is managed by the UK Debt Management Office, an executive agency of HM Treasury. Prior to April 1998, gilts were issued by the Bank of England.^[8] Purchase and sales services are managed by Computershare.^[9]

UK gilts have maturities stretching much further into the future than other European government bonds, which has influenced the development of pension and life insurance markets in the respective countries.

A conventional UK gilt might look like this – "Treasury stock 3% 2020".^[10] On the 27 of April 2019 the United Kingdom 10Y Government Bond had a 1.145% yield. Central Bank Rate is 0.10% and the United Kingdom rating is AA, according to Standard & Poor's.^[11]

United States

The U.S. Treasury offered several types of bonds with various maturities. Certain bonds may pay interest, others not. These bonds could be:

• Savings bonds: they are considered one of the safest investments.

• Treasury notes (T-notes): maturity of these bonds is two, three, five or 10 years, they provided fixed coupon payments every six months and have face value of $1,000.

• Treasury bonds (T-bonds or long bonds): are the treasury bonds with the longest maturity, from twenty years to thirty years. They also have a coupon payment every six months.

• Treasury Inflation-Protected Securities (TIPS): are the inflation-indexed bond issued by the U.S. Treasury. The principal of these bonds is adjusted to the Consumer Price Index. In other words, the principal increases with inflation and decreases with deflation.

The principal argument for investors to hold U.S. government bonds is that the bonds are exempt from state and local taxes.

The bonds are sold through an auction system by the government. The bonds are buying and selling on the secondary market, the financial market in which financial instruments such as stock, bond, option and futures are traded.

资本主义骗局  让政府借钱  大紧缩骗局

大紧缩骗局 The great austerity shell game

https://www.theguardian.com/commentisfree/2013/nov/04/great-austerity-shell-game

Richard Wolff 2013 年 11 月 4 日星期一

资本主义骗局是这样运作的：让政府借钱来应对危机，然后坚持削减开支来支付。猜猜谁会输

英国和德国的中右翼政府这样做。法国和意大利的中左翼政府也是如此。奥巴马和共和党也这么做。他们都在必要时对经济实施“紧缩”计划，以摆脱自 2007 年以来困扰他们的危机。政客和经济学家现在实施紧缩政策，就像医生曾经在病人的皮肤上贴芥末膏一样。

紧缩政策假定当今的主要经济问题是增加国家债务的政府预算赤字。紧缩政策主要通过削减政府开支来解决这些问题，其次是通过限制增税。削减支出、增加收入确实会减少政府的赤字和借贷需求。

国家债务的减少或下降取决于每个政府的支出减少多少和税收增加多少。奥巴马在 2013 年的紧缩政策始于 1 月 1 日，当时他将每个人的年收入工资税提高到 113,700 美元。然后，在 3 月 1 日，“自动减支”降低了联邦支出。因此，2013 年的美国赤字将比 2012 年大幅下降。

奥巴马可能会实施更多紧缩政策：削减社会保障和医疗保险福利，以与共和党妥协。同样，欧洲各国政府也维持其“紧缩”计划。即使是官方上“反紧缩”和“社会主义”的法国政府，也有一份新预算，其中社会支出也进行了典型的紧缩削减。

积累的证据表明，紧缩计划通常会加剧经济衰退。那么，为什么它们仍然是大多数资本主义政府的首选政策呢？

当资本主义经济崩溃时，大多数资本家会要求——政府也会提供——信贷市场救助和经济刺激。然而，企业和富人反对对他们征收新税来支付刺激和救助计划。相反，他们坚持认为政府应该借入必要的资金。自 2007 年以来，世界各地的资本主义政府都为这些昂贵的计划大量借款。因此，他们出现了巨大的预算赤字，国家债务飙升。

因此，大量借贷是资本家应对其系统最新危机的首选政策。这对他们很有帮助。

借贷支付了政府对银行、其他金融公司和其他选定大公司的救助费用。借贷使刺激支出得以恢复对商品和服务的需求。借贷使政府能够支出失业补偿、食品券和其他抵消危机引发的痛苦的措施。

通过这些方式，借贷有助于减少那些被解雇、被赶出家门、被剥夺工作保障和福利等人群的批评、怨恨、愤怒和反体制倾向。政府借贷对资本家产生了这些积极的影响——同时还使他们免于纳税以获得这些结果。

这还不是全部。企业和富人利用他们通过阻止政府向他们征税而节省下来的资金来提供政府所需的巨额贷款。中低收入人群几乎无法向政府提供任何贷款。企业和富人实际上是用贷款代替向政府贷款，而不是支付更多的税。对于这些贷款，政府必须支付利息并最终偿还。

政府借贷给企业和富人带来了相当丰厚的回报。这对资本家来说是一笔非常划算的交易。

然而，这笔划算的交易又带来了一个新问题。政府从哪里找到资金，首先，支付所有借款的利息，其次，偿还贷款人？企业和富人担心他们可能仍需纳税来提供这些资金。他们决心避免缴纳此类税款——就像他们一开始就避免被征税来支付刺激和救助计划一样。

因此，紧缩政策是资本家首选的第二项政策，是在政府努力应对经济危机时避免提高税收的第二种方法。企业和富人通过大声坚持当今的主要经济问题不是失业、失去工作保障和福利、房屋止赎以及创纪录的收入和财富不平等来提倡紧缩政策。相反，关键问题是政府赤字和不断上升的国家债务。必须削减这些。

要做到这一点，应该适度提高税收或根本不加税（以避免“伤害”经济）。因此，关键的解决方案是削减政府在就业、社会福利和社会服务方面的支出。通过这些削减节省下来的资金应该用来支付国家债务的利息并减少债务。

因此，资本主义应对其反复出现的危机的方式是一个了不起的两步走。第一步，大规模借贷为刺激和救助计划提供资金。第二步，澳大利亚

资本家为借贷买单。

这种忙碌将资本主义危机的大部分成本转嫁到中低收入人群身上。这种转移通过紧缩计划实现的失业率上升、工资下降和政府服务减少而实现。持续减少税收增长也同样如此——尤其是对企业和富人的税收增长。

除了少数例外，世界各地的主要政党都实施了资本主义的两步忙碌。只有当中低收入人群的大规模反对足够有组织，可能威胁到资本主义本身时，资本家才会在借贷和紧缩政策上动摇和分裂。一些资本家随后与反对派合作，支持“新政”，而不是紧缩政策。

即便如此，一旦度过了眼前的危机，资本家就会恢复到他们偏爱的借贷和紧缩政策。美国从 1929 年到现在的历史很好地教会了我们这个教训。

资本家知道他们的制度是不稳定的。他们从来没有阻止过危机的复发。相反，他们依靠政策来“管理”危机。两步走的策略——借钱刺激经济和救助，然后紧缩政策——通常能起到作用。凯恩斯主义者提倡借钱，当紧缩政策随之而来时，他们似乎感到惊讶，甚至愤怒。

企业和富人本来就不应该逃避税收，因为他们帮助引发了危机；他们在危机前的几十年里致富最多；他们最有能力支付克服危机的费用。如果他们被征税来支付刺激和救助的费用，就不需要借钱或紧缩政策了。

对企业和富人征税也会产生后果，但它们产生的社会成本要小得多，而且主要落在那些最有能力应对这些后果的人身上。

但任何有组织的反对派，只要足够强大，让企业和富人为资本主义的危机买单，也可能会质疑资本主义本身。在经历了近六年的危机后，人们提出了一个问题：“我们难道不能比资本主义做得更好吗？”推动，要求讨论、辩论和民主决策。

The great austerity shell game

https://www.theguardian.com/commentisfree/2013/nov/04/great-austerity-shell-game 

Richard Wolff  Mon 4 Nov 2013 

Here's how the capitalist scam works: let government borrow for crisis bailouts, then insist cuts pay for them. Guess who loses

Center-right governments in Britain and Germany do it. So do the center-left governments in France and Italy. Obama and the Republicans do it, too. They all impose "austerity" programs on their economies as necessary to exit the crisis afflicting them all since 2007. Politicians and economists impose austerity now much as doctors once stuck mustard plasters on the skins of the sick.

Austerity policies presume that the chief economic problems today are government budget deficits that increase national debts. Austerity policies solve those problems mainly by cutting government spending, and secondarily, by limited tax increases. Reducing expenditures while raising revenues does cut governments' deficits and their needs to borrow.

National debts grow less or drop depending on how much each government's expenditures decrease and its taxes increase. Obama's austerity policies during 2013 started 1 January, when he raised payroll taxes on everyone's annual incomes up to $113,700. Then, on 1 March, the "sequester" lowered federal expenditures. Thus, 2013's US deficit will drop sharply from 2012's.

Obama will likely impose more austerity: cutting social security and Medicare benefits to compromise with Republicans. Similarly, European governments maintain their "austerity" programs. Even France's government, officially "anti-austerity" and "socialist", has a new budget with typical austerity cuts in social expenditures.

The accumulated evidence shows that austerity programs usually make economic downturns worse. Why, then, do they remain the preferred policy for most capitalist governments?

When capitalist economies crash, most capitalists request – and governments provide – credit market bailouts and economic stimuli. However, corporations and the rich oppose new taxes on them to pay for stimulus and bailout programs. They insist, instead, that governments should borrow the necessary funds. Since 2007, capitalist governments everywhere borrowed massively for those costly programs. They thus ran large budget deficits and their national debts soared.

Heavy borrowing was thus capitalists' preferred first policy to deal with their system's latest crisis. It served them well.

Borrowing paid for government rescues of banks, other financial companies, and selected other major corporations. Borrowing enabled stimulus expenditures that revived demand for goods and services. Borrowing enabled government outlays on unemployment compensation, food stamps, and other offsets to crisis-induced suffering.

In these ways, borrowing helped reduce the criticism, resentment, anger, and anti-system tendencies among those fired from jobs, evicted from homes, deprived of job security and benefits, etc. Government borrowing had these positive results for capitalists – while saving them from paying taxes to get those results.

Nor is that all. Corporations and the rich used the money they saved by keeping governments from taxing them to provide the huge loans governments therefore needed. Middle- and lower-income people could lend little if anything to their governments. Corporations and the rich, in effect, substituted loans to the government instead of paying more in taxes. For those loans, governments must pay interest and eventually repay them.

Government borrowing rewards corporations and the rich quite nicely. It amounts to a very sweet deal for capitalists.

Yet, that sweet deal raises a new problem. Where will governments find funds, first, to pay interest on all the borrowing, and second, to pay back the lenders? Corporations and the rich worry that they might still be taxed to provide those funds. They are determined to avoid such taxes – just as they avoided being taxed to pay for stimulus and bailout programs in the first place.

Austerity is thus capitalists' preferred second policy, a second way to avoid higher taxes as governments struggle with economic crises. Corporations and the rich promote austerity by loudly insisting that today's key economic problems are not unemployment, lost job security and benefits, home foreclosures, and record-breaking inequalities of income and wealth. Rather, the key problems are government deficits and rising national debt. They must be cut.

To do that, taxes should be raised modestly or not at all (to avoid "hurting" the economy). The key solution is thus to cut government outlays on jobs, social benefits, and providing social services. Money saved by those cuts should be used instead to pay interest on the national debt and reduce it.

Capitalism's way of dealing with its recurring crises is thus a remarkable two-step hustle. In step one, massive borrowing funds stimulus and bailout programs. In step two, austerity pays for the borrowing.

This hustle shifts most of the costs of capitalist crises onto the backs of middle- and lower-income people. The shift occurs through the higher unemployment, lower wages, and reduced government services achieved by austerity programs. It occurs as well in the sustained minimization of tax increases – especially on corporations and the rich.

With few exceptions, major political parties everywhere have imposed capitalism's two-step hustle. Only when mass opposition from middle- and lower-income people is sufficiently organized to possibly threaten capitalism itself do capitalists waver and split over borrowing and austerity. Some capitalists then collaborate with that opposition to support "New Deals", instead of austerity.

Even then, once past the immediate crisis, capitalists revert to their preferred policies of borrowing and austerity. US history from 1929 to the present teaches that lesson well.

Capitalists know their system is unstable. They have never yet prevented recurring crises. They rely instead on policies to "manage" them. The two-step hustle – borrowing for stimulus and bailouts and then austerity – usually does the job. Keynesians promote the borrowing and then seem surprised, even outraged, when austerity follows.

Corporations and the rich should not have escaped taxation in the first place because they helped to cause the crisis; they enriched themselves the most in the decades before the crisis; and they can best afford to pay to overcome the crisis. Had they been taxed to pay for stimulus and bailout, no need would have arisen for borrowing or austerity.

Taxing corporations and the rich would have consequences too, but they would generate far fewer social costs and fall mostly on those best able to cope with them.

But any organized opposition strong enough to make corporations and the rich pay for capitalism's crises would likely also question capitalism itself. Emerging from nearly six years of crisis, the question "can't we do better than capitalism?" pushes forward, demanding discussion, debate, and democratic decision.
