The world economy is defying gravity. That cannot last - The Economist   

Even as wars rage and the geopolitical climate darkens, the world economy has been an irrepressible source of cheer. Only a year ago everyone agreed that high interest rates would soon bring about a recession. Now even the optimists have been confounded. America’s economy roared in the third quarter, growing at a stunning annualised pace of 4.9%. Around the world, inflation is falling, unemployment has mostly stayed low and the big central banks may have stopped their monetary tightening. China, stricken by a property crisis, looks likely to benefit from a modest stimulus. Unfortunately, however, this good cheer cannot last. The foundations for today’s growth look unstable. Peer ahead, and threats abound.

The irrepressible economy has encouraged bets that interest rates, though no longer rising rapidly, will not fall by much. Over the past week the European Central Bank and Federal Reserve have held rates steady; the Bank of England was expected to follow suit shortly after we published this on November 2nd. Long-term bond yields have accordingly risen sharply. America’s government must now pay 5% to borrow for 30 years, up from just 1.2% in the depths of the pandemic recession. Even economies known for low rates have seen sharp increases. Not long ago Germany’s borrowing costs were negative; now its ten-year bond yield is nearly 3%. The Bank of Japan has all but given up on its promise to peg ten-year borrowing costs at 1%.

Some people, including Janet Yellen, America’s treasury secretary, say these higher interest rates are a good thing—a reflection of a world economy in the rudest of health. In fact, they are a source of danger. Because higher rates are likely to persist, today’s economic policies will fail and so will the growth they have fostered.
