KUALA LUMPUR, Aug 4 — Malaysia’s ringgit fell for a fourth day as Brent crude dropped below US$50 (RM193.30) a barrel for the first time since January, weighing on the net oil exporter’s revenue.

The currency declined 0.3 per cent to 3.8650 per dollar as of 10:01am in Kuala Lumpur, adding to yesterday’s 0.8 per cent loss, prices from local banks compiled by Bloomberg show. It earlier fell to 3.8688, the lowest level since September 1998 when it weakened to 3.9340.

The ringgit’s weakness yesterdday suggested the central bank was “stepping away from supporting” the currency, said Khoon Goh a strategist at Australia & New Zealand Banking Group Ltd. A report on Wednesday may show Malaysia’s exports contracted in June for a fifth month in 2015. The prospect Iran will flood an already oversupplied market once sanctions are lifted helped contribute to Brent’s 53 per cent slide in the past 12 months.

“With oil prices falling due to concern over increased Iranian supply, this will put further downward pressure on the ringgit,” said Singapore-based Goh. “We have seen depreciation pressure that had been building up.”

The currency has dropped 9.5 per cent this year in Asia’s worst performance due to a combination of slumping oil prices, a probe into funds linked to state investment company 1Malaysia Development Bhd. that’s embroiled Prime Minister Datuk Seri Najib Razak and the outlook for higher US interest rates.
