Prices have increased sharply over the past several months, rising 3.3% in March before going up to 3.8% in April. In February, before the conflict began, inflation was at 2.4%. Energy prices were once again responsible for the increase in the consumer price index, according to new data from the Bureau of Labor Statistics, accounting for 60% of the overall monthly increases.

Warsh said he believes the rates, which stand at 3.5% to 3.75%, should be lowered, aligning himself with Donald Trump , who has spent the last year trying to coerce the central bank into lowering rates. Even though prices are rising, the president is unlikely to be undeterred from calling for rate cuts. On Tuesday, Trump told reporters that he didn’t think US fuel prices were “very high, relatively speaking.” The Fed typically decreases rates to address high unemployment, at the risk of raising prices.
