The ringgit extended its upward trend against the US dollar and major currencies at the start of the week ahead of Malaysia's second-quarter gross domestic product (GDP) data due on Friday.
The market is now eyeing the Malaysian GDP print for further tariff setting and trade talks that could be much stronger than expected to support the ringgit's rise.
At 10.20am, the ringgit was at 4.2320, stable since it opened early Tuesday in the Asian session.
Bank Muamalat Malaysia Bhd Chief Economist Dr Mohd Afzanizam Abdul Rashid said the ringgit is expected to trade in a range of RM4.23 to RM4.25 against the US dollar today.
He said the US Dollar Index (DXY) rose 0.35 per cent to 98.52 points ahead of the release of the US Consumer Price Index (CPI) report tonight.
For now, the Federal Reserve (Fed) is seen to remain steady at its upcoming meeting in September.
At the opening, the ringgit closed stronger against major currencies.
It rose against the yen to 2.8528/8658 from 2.8657/8686 at Monday's close, rose against the euro to 4.9097/9317 from 4.9269/9316 and rose against the British pound to 5.6777/7033 from 5.6933/6987.
The ringgit also moved higher against its regional peers.
It strengthened against the Singapore dollar to 3.2841/2999 from 3.2936/2973 and rose against the Thai baht to 13.0198/0884 from 13.0569/0769.
The local currency rose to 259.6/260.9 against the Indonesian rupiah from 259.9/260.3 previously, and rose against the Philippine peso to 7.41/7.44 from 7.42/7.43
