KUALA LUMPUR: The ringgit opened moderately higher against the US dollar as investors remain concerned ahead of the release of US inflation data later today which may provide more clues on the next US interest rate increase.

At 9.05am, the local unit stood at 4.2135/2165 against the greenback, from Thursday's close of 4.2200/2165.

The ringgit, however, was mixed against other major currencies.

It inched up against the Singapore dollar to 3.1133/1162 from Thursday's 3.1153/1187, but weakened against the British pound to 5.5917/5970 from 5.5772/5841 yesterday.

It strengthened against the euro to 4.9900/9949 from 5.0007/0071 yesterday, but eased against the yen to 3.7553/7587 from 3.7538/7577 yesterday. -- BERNAMA
