At 9 am, the local note stood at 4.2370/2400 versus the greenback compared to Monday's close of 4.2350/2390.
"The ringgit looks particularly vulnerable as Malaysia's political crisis deepens and oil prices remain soft,” said OANDA Asia Pacific senior market analyst Jeffrey Halley.
He said the COVID-19 virus fears were also weighing on sentiment in Asia in general, with markets casting a wary eye towards the evolution of the situation in China, particularly partial port closures.
Meanwhile on the external front, ActivTrades trader Dyogenes Rodrigues Diniz said forex investors would be focusing on the US retail sales data to come out later today, which may offer clues on US consumption and might determine the behavior of the greenback in the next few days.
"A higher-than-expected reading could cause the US dollar to break above 4.2370 and reach the 4.2890 level, while a lower-than-expected number could cause a breakout below the 4.2150 level and further down to 4,1750,” he told Bernama.
Meanwhile, the local note was traded mixed against a basket of major currencies.
It fell against the Singapore dollar to 3.1237/1264 from 3.1227/1259 at Monday’s close and dipped against the Japanese yen to 3.8786/8814 from 3.8732/8769.
The ringgit was, however, slightly better against the euro at 4.9886/9922 compared to 4.9893/9940 yesterday and appreciated against the British pound to 5.8623/8665 from 5.8680/8736 previously. - Bernama
