Markets were also supported by a private survey showing that manufacturing in the 19-country eurozone improved marginally in April. The manufacturing purchasing managers' index by IHS Markit was 47.9 in April, up from 47.5 in March. Readings above 50 indicate expansion, while lower numbers indicate contraction on the 100-point scale.
U.S. stocks were set for modest gains. The future contract for the S&P 500 index added 0.2% to 2,928, while that for the Dow Jones Industrial Average was up less than 0.1% at 26,407. Sentiment was shaken somewhat by the Fed, which left its benchmark interest rate — which determines the cost of borrowing for individuals and businesses — in a range of 2.25% to 2.5% as expected on Wednesday.
Some traders had hoped the Fed would signal a rate cut to lift persistently low inflation to its 2% target rate. The Fed's preferred 12-month inflation barometer is running at about 1.5%. But Chairman Jerome Powell steered clear of this at a news conference. "The committee is comfortable with our current policy stance," he said.
"The world's most important central bank is apparently in no rush to adjust interest rates, suggesting that investors who had been pricing in a U.S. rate cut this year had their expectations misplaced," Han Tan of FXTM said in a market commentary.
