WASHINGTON - Federal Reserve officials left interest rates unchanged and pointed to improvements in the US economy as they signalled a more cautious approach to potential future adjustments.

The Federal Open Market Committee voted 10-2 on Jan 28 to hold the benchmark federal funds rate in a range of 3.5 per cent to 3.75 per cent. Governors Christopher Waller and Stephen Miran dissented in favor of a quarter-point reduction.
