Washington:The US Federal Reserve on Wednesday left interest rates unchanged, in line with market expectations, reaffirming its position to be patient with future rate hikes.In support of the goals to foster maximum employment and price stability, the Federal Open Market Committee decided to maintain the target range for the federal funds rate at 2.25 per cent to 2.5 per cent, the central bank said in a statement after concluding a two-day policy meeting, Xinhua reported.The committee continues to view sustained expansion of economic activity, strong labour market conditions, and inflation near its 2 per cent objective as the most likely outcomes, the US Federal Reserve said."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," it said.The US Federal Reserve in December raised short-term interest rates by a quarter of a percentage point, but signalled a slower pace of rate hikes in 2019 as the US economy was expected to cool down.
