Ringgit weakens as stronger US inflation data bolsters dollar

On Friday morning in Kuala Lumpur, the ringgit slipped against the US dollar as traders absorbed fresh evidence that American inflation remained stubborn. By 8 am, the Malaysian currency had weakened to 4.0680 against the greenback, down from Thursday's close of 4.0630. The shift was modest but unmistakable—a market response to numbers released overnight that suggested price pressures in the US economy were not easing as hoped.

The culprit was American producer prices. In August, the US producer price index climbed to 5.4 percent year-on-year, outpacing both the previous month's 4.8 percent and the consensus forecast of 5.3 percent. Core producer prices—a measure that strips out volatile food and energy costs—also accelerated, rising to 4.6 percent from 4.3 percent. These figures mattered because they signaled that businesses were passing rising costs directly to consumers, a dynamic that typically feeds into consumer inflation down the line. When the consumer price index was due to be published that same evening, analysts expected it would tell a similar story.

Dr Mohd Afzanizam Abdul Rashid, chief economist at Bank Muamalat Malaysia, laid out the chain of reasoning. Stronger producer prices meant the case for the Federal Reserve to raise interest rates was gaining traction. The US Dollar Index, which measures the greenback's strength against a basket of major currencies, jumped 0.26 percent to 99.077 points. A stronger dollar typically pressures emerging market currencies like the ringgit, which become less attractive to investors when dollar returns are rising.

Stephen Innes, global strategist at Quintex Intel, quantified the shift in market expectations. The producer price surprise had pushed the probability of a Fed rate hike in the following week to around 75 percent. That was a significant move—enough to keep pressure on regional currencies, particularly as global equities weakened and investors retreated to safer bets. Yet Innes offered a note of restraint about how far the ringgit might fall. The currency, he suggested, would not weaken dramatically against the dollar because it had other sources of support.

Those supports were distinctly Malaysian. Bank Negara Malaysia, the country's central bank, had taken a more hawkish stance than many of its regional peers, making ringgit assets more attractive to yield-seeking investors. Domestic economic indicators remained resilient, buoyed by investment and export activity tied to the artificial intelligence boom—a sector driving significant capital flows into the region. These tailwinds provided a floor beneath the currency even as Fed rate hike expectations climbed.

Against other major currencies, the ringgit actually gained ground on Friday. It strengthened to 2.6337 against the Japanese yen from 2.6431, edged up to 4.7238 versus the euro from 4.7269, and rose to 5.4967 against the British pound from 5.5046. The pattern reflected a broader market dynamic: the ringgit was weakening specifically against the dollar, not across the board. Against regional peers, the picture was mixed. The currency gained against the Singapore dollar and Thai baht but slipped against the Philippine peso and held steady against the Indonesian rupiah.

The morning's trading encapsulated a familiar tension in emerging market currency markets. External forces—in this case, American inflation data and the prospect of higher US rates—pushed the ringgit lower. But domestic strengths and the relative attractiveness of Malaysian assets provided countervailing support. The ringgit's slight opening weakness was less a rout than a recalibration, a market pricing in new information while acknowledging that Malaysia's economic position offered some insulation from the full force of dollar strength.
