Lockdowns in Europe are a warning to the United States

The coronavirus is surging again in Europe, forcing harsh new restrictionsin London and Paris as governments carefully weigh their next steps. That's bad news for the region's economic recovery — and puts the United States on notice ahead of a difficult winter.

What's happening: Paris has imposed an overnight curfew. In London, people from different households are banned from meeting indoors. The measures are an attempt to stem the rapid rise in Covid-19 cases across the continent as hospital capacity again becomes a concern.

Stocks in London, Paris, Milan and Frankfurt sold off sharply on Thursday before rebounding Friday. Markets aren't tanking like they did in March, but the quick change in climate still presents a cautionary tale.
