A key index of underlying inflation that is closely followed by the Federal Reserve remained elevated last month, keeping the Fed on track to raise interest rates next week for the 10th time since March of last year.
The index, which excludes volatile food and energy costs to capture “core” prices, rose 0.3% from February to March and 4.6% from a year earlier — still far above the Fed’s 2% target rate. Some Fed officials are concerned that core inflation hasn’t declined much since reaching 4.7% in July.
