The Global Currency Wars Have Begun Because, Well, Inflation

The US dollar had been soaring—now up 7% for the year—as the Federal Reserve prepared to aggressively combat inflation. And so one by one, central bankers elsewhere, just as desperate to tame the relentless march of inflation in their own backyards, began sending not-so-subtle signals that they would for once welcome a stronger currency—which helps reduce the cost of imports by boosting buying power abroad. It’s a form of intervention so rare that their jawboning alone moved markets. On June 16, two of them upped the ante: Switzerland surprised traders with the first rate increase since 2007, sending the franc soaring to its highest level in seven years. Hours later, the Bank of England announced its own rate increase and signaled bigger hikes to come.
