The U.S. dollar was mostly flat on Tuesday as investors awaited slew of economic data this week along with minutes of the last Federal Reserve meeting that will shed light on the Central bank’s thinking around interest rates and inflation. The dollar index, which measures the greenback against six major currencies, has made a subdued start to 2023 and was last up 0.068% at 103.710. The index rose 8% last year in its biggest annual jump since 2015 on the back of the Fed raising interest rates to tackle inflation.
