NEW YORK, Jan. 30 (Xinhua) -- The U.S. dollar slid on Wednesday, as the U.S. Federal Reserve decided to keep interest rates unchanged and pledged patience in future policy making on interest rates adjustments, signaling more caution on its outlook.

"The Committee judges decided to maintain the target range for the federal funds rate at 2-1/4 to 2-1/2 percent," the Federal Open Market Committee (FOMC) said in a statement, after it wrapped up its two-day policy meeting on Wednesday.

"In light of global economic and financial developments and muted inflation pressures, the Committee will be patient as it determines what future adjustments to the target range for the federal funds rate may be appropriate to support these outcomes," the FOMC said in a statement on Wednesday.

Fed Chairman Jerome Powell also said the case for raising interest rates "has weakened" in a news conference after the FOMC meeting on Wednesday.

Investors have expected that the Fed's interest rate hikes this year would be less than the four times it undertook in 2018. That would possibly increase the money flow in global financial markets later this year, which makes the dollar less valuable compared with other currencies.
