Few think another G7 central bank would be bold enough to intervene directly as Japan did on Thursday. But they say markets should prepare for more verbal intervention and more aggressive rate hikes as policymakers try to thwart the U.S. currency's ascent. The dollar surge follows aggressive Federal Reserve interest rate hikes, recession fears and geopolitical uncertainty following Russia's invasion of Ukraine. The yen, its central bank sticking to ultra-loose policy even as others raise rates, has been the biggest loser. Richard Benson, co-chief investment officer at Millennium Global Investments, said aside from the SNB, which intervenes regularly, another central bank intervention was unlikely.
