US Treasury yields eased for a second consecutive day and the dollar rose on Wednesday after Federal Reserve Chairman Jerome Powell said there is a risk the US central bank's interest rate hikes will slow the economy too much, but the bigger risk is persistent inflation.
The S&P 500 ended slightly lower, and looked set to put in the worst first-half for the US benchmark index in more than five decades.
"The clock is kind of running on how long will you remain in a low-inflation regime. The risk is that because of the multiplicity of shocks you start to transition into a higher inflation regime and our job is to literally prevent that from happening and we will prevent that from happening," Powell said at a European Central Bank conference.
Investors have worried that an aggressive push by the Fed to dampen inflation will tip the economy into recession. Matt Stucky, senior portfolio manager at Northwestern Mutual Wealth Management Company, said investors are waiting for Thursday's data on the personal consumption expenditures (PCE) price index.
"A slowdown or a mild recession is almost consensus at this point as it relates to the economy," he said. "The question from here is how much does the Fed have to do to get inflation under control."
A Commerce Department report on Wednesday showed that the US economy contracted slightly more than previously estimated in the first quarter as the trade deficit widened to a record high and a resurgence in COVID-19 infections hurt spending on services like recreation.
