Malaysia's Currency Holds Ground as Dollar Index Climbs on Hormuz Tensions

Early Session Gains Against Select Majors

Malaysia's ringgit opened Tuesday morning with selective strength against major currencies, climbing versus the Japanese yen and euro while slipping marginally against the British pound. At 8:00 a.m. local time, the currency stood at 4.0900/0975 per US dollar, edging down from the previous session's close of 4.0885/0930.

The modest depreciation against the greenback came as the dollar index gained 0.27 per cent to reach 99.811 points, supported by a rebound in crude oil markets following the reopening of the Strait of Hormuz. The waterway, through which roughly one-fifth of global oil supply passes, had been closed temporarily, and its return to operation has kept energy prices elevated rather than triggering the expected relief rally.

Against the yen, the ringgit improved to 2.5696/5746 from the prior close of 2.5736/5766, while it strengthened to 4.7223/7310 versus the euro from 4.7247/7299. The British pound, however, extended its advantage, with the ringgit retreating to 5.5260/5361 from 5.5170/5231.

Geopolitical Friction Underpins Dollar Demand

The dollar's resilience reflects an unusual interplay of geopolitical risk and monetary policy expectations. According to Bank Muamalat Malaysia chief economist Mohd Afzanizam Abdul Rashid, US President Donald Trump's refusal to entertain Iran's compensation demands over regional damages has injected fresh uncertainty into Middle East dynamics. Trump's stance, which places liability squarely on Tehran, has been interpreted by currency markets as a hawkish signal that could influence Federal Reserve calculus.

"The news appears to be dollar-positive as it could improve the odds of a rate hike in the upcoming September Federal Open Market Committee," Mohd Afzanizam noted. The Fed's September gathering has become a focal point for traders, particularly after Friday's weaker-than-expected US employment data failed to weaken the American currency as conventional wisdom would predict.

That disconnect between soft labor market figures and a firmer dollar underscores the degree to which geopolitical premium and energy-market volatility are now driving short-term currency flows. Elevated crude prices tend to support the dollar through multiple channels: they reinforce inflationary pressures that argue for tighter monetary policy, and they increase demand for dollar-denominated oil settlements.

Range-Bound Outlook Amid Mixed Signals

Mohd Afzanizam expects the ringgit to remain range-bound in the near term, caught between conflicting macroeconomic signals. On one hand, Friday's disappointing US jobs report should, in theory, ease rate-hike expectations and weaken the dollar. On the other, the geopolitical backdrop and oil-price trajectory are lending the greenback a bid that labor-market softness has so far failed to erode.

This tug-of-war leaves the ringgit without a clear directional catalyst. Malaysia's own fundamentals remain broadly supportive: export data have held up, domestic demand shows resilience, and the current account remains in surplus. Yet the currency's trajectory in the short run hinges less on these domestic factors than on the interplay between Fed policy expectations and risk sentiment across emerging Asia.

Central banks across the region face a similar calculus. If the Fed does proceed with a September hike, the policy divergence between Washington and regional capitals will widen, potentially triggering capital outflows from emerging-market bonds and equities. Conversely, if the Fed holds steady, the relief rally in regional currencies could prove short-lived if oil prices continue to climb and inflationary pressures build.

Mixed Performance Across Regional Peers

The ringgit's performance against Southeast Asian counterparts was uneven. It firmed slightly against the Singapore dollar, moving to 3.1943/2004 from 3.1961/2002, a modest improvement that reflects Singapore's own vulnerability to global trade headwinds and slowing manufacturing activity in the city-state.

Against the Thai baht, however, the ringgit softened to 12.3921/4204 from 12.3894/4079. Thailand's currency has been buoyed by a recovery in tourist arrivals and stronger-than-expected consumer spending, factors that have offset concerns about the kingdom's export sector.

The ringgit held nearly flat against the Indonesian rupiah at 230.3/230.8 versus 230.2/230.6, and showed minimal movement against the Philippine peso at 6.73/6.75 from 6.73/6.74. Both Jakarta and Manila are contending with their own inflation and rate-policy challenges, leaving their currencies range-bound as well.

Oil, Fed, and the Path Forward

The immediate outlook for the ringgit will be shaped by two variables: the trajectory of crude oil prices and the tone of Fed communications in the lead-up to the September meeting. If Brent crude sustains gains above recent levels, inflationary pressure in the US will argue for a more aggressive Fed stance, likely keeping the dollar supported and emerging-market currencies on the defensive.

Conversely, any de-escalation in Middle East tensions or a surprise build in US crude inventories could ease oil prices and take some pressure off the dollar. In that scenario, the ringgit and regional peers would likely find room to appreciate, particularly if upcoming US data continue to signal labor-market cooling.

For now, the ringgit is navigating a narrow channel, balancing domestic resilience against external volatility. Traders will be watching not only the Fed's September decision but also any shifts in the Trump administration's stance on Iran and the broader Middle East, factors that have moved from the background to the foreground of currency markets in a matter of days.
