Top central bankers express 'full solidarity' with Fed Chair Powell in clash with Trump

They added that “the independence of central banks is a cornerstone of price, financial and economic stability in the interest of the citizens that we serve. It is therefore critical to preserve that independence, with full respect for the rule of law and democratic accountability."

The dispute is ostensibly about Powell’s testimony to Congress in June over the cost of a massive renovation of Fed buildings. But in a statement Sunday, Powell, abandoning his previous attempt to ignore Trump’s relentless criticism, called the administration’s threat of criminal charges “pretexts’’ in the president’s campaign to seize control of U.S. interest rate policy from the Fed’s technocrats.

Trump has repeatedly criticized Powell and the Fed for not moving faster to cut rates. Economists warn that a politicized Fed that caves in to the president’s demands will damage its credibility as an inflation fighter and likely lead investors to demand higher rates before investing in U.S. Treasurys.

Fed actions have impacts around the world due to the U.S. dollar's role as the leading currency for trade transactions and central bank reserves. Fed interest rate changes can affect the dollar's exchange rate against other currencies and the value of foreign investors′ U.S. assets.

Politically independent central banks have become a cornerstone of the global economy because they can more easily take steps to fight inflation, such as rate hikes, that are unpopular in the short term but preserve price stability over the longer term.
