Central banks raise rates again as Fed drives global inflation fight

By Francesco Canepa and Howard Schneider

FRANKFURT/WASHINGTON (Reuters) - Global central banks continued raising interest rates on Thursday, following the U.S. Federal Reserve in a fight against inflation that is sending shockwaves through financial markets and the economy.

Japan, the outlier among major developed economies, kept interest rates steady on Thursday only to be punished as traders pushed the yen to a record low against the dollar - prompting the first intervention by Japanese authorities to support the currency since 1998.

It was a potential sign of a massive adjustment to come as the world adapts to U.S. interest rates rising to levels not seen since the global financial crisis 15 years ago prompted the Fed to slash its policy rate to zero and unleash massive rounds of bondbuying.

That era of cheap liquidity, which lasted through the worst of the coronavirus pandemic and until inflation became a prominent risk, is now ending. U.S. interest rates and the U.S. dollar serve as reference points for borrowing costs around the world, and Federal Reserve officials have now flagged not just plans to continue tightening monetary policy, but to keep it tight for years to come in what may for many countries amount to a fresh financial shock - and a broad repricing of bonds, stocks, and other financial instruments.

The value of the dollar is soaring, helping ease inflation in the United States even as it raises the costs of many dollar-priced imports for other countries, a factor that may have figured into Japan's intervention.

Some analysts feel more is bound to follow.

"Intervening in markets tends to result in...less optimal economic outcomes than would otherwise result," RSM Chief Economist Joe Brusuelas wrote after Japan's action. "But the current inflation shock may outweigh this reluctance. We may be entering an era of intervention in foreign exchange markets."

In the aftermath of the 2007 to 2009 financial crisis, central bankers often accused each other of waging currency wars to cheapen local money to promote exports, an accusation levelled pointedly at the Fed. Inflation may now prompt a similar tension in the other direction.U.S. Treasury officials, who monitor global currency policies closely for signs countries are intervening to gain an advantage, took note of Japan's move on Thursday as an effort to "reduce recent heightened volatility" in the yen, but stopped short of endorsing it.

U.S. Treasury Secretary Janet Yellen, asked in July about the yen's substantial depreciation, said currency intervention was warranted only in "rare and exceptional circumstances."
