Asian FX is being driven by a push and pull between supportive regional growth and external US headwinds. MUFG points to stronger growth differentials versus the US, with AI-related export economies such as South Korea, Taiwan, Malaysia and Singapore seen as better placed. At the same time, currencies face pressure from a stronger Dollar, sticky US yields and uncertainty around evolving Federal Reserve policy under Chair Kevin Warsh, alongside shifts in oil-led risk sentiment tied to the Iran conflict.

Oil prices have risen on the developments, but MUFG argues the overall level remains low enough to cushion broader sentiment. Recent underperformers such as INR and PHP have been more resilient in the near term due to lower oil prices, while low-yielding Asian currencies have lagged as markets refocus on rate differentials. MUFG’s framework on past Fed rate cycles suggests yield differentials are only one driver, with growth differentials and risk sentiment also influential; a materially more hawkish Fed could still weigh on Asia FX if it erodes risk appetite, though the base case remains that Asia’s growth and improving sentiment can offset Fed-related drag.

Regional Growth Versus US Monetary Headwinds

We see a clear tug-of-war for Asian currencies right now, pulled between a hawkish US Federal Reserve and strong regional growth. The US 10-year Treasury yield is holding firm above 4.5% in June 2026, reflecting a Fed under Chair Warsh that remains focused on stubborn inflation numbers. This environment naturally strengthens the US dollar and puts pressure on lower-yielding Asian currencies.

However, we believe stronger growth in Asia, especially in AI-related export economies, will provide a key tailwind. For instance, recent data for May 2026 showed South Korea’s semiconductor exports surged over 15% year-on-year, a trend mirrored in Taiwan and Malaysia. This robust export cycle is creating a fundamental strength that rate differentials alone do not capture.

Currency Strategies Amid Growth and Risk Shifts

This leads us to favor long positions in currencies like the South Korean won and the Taiwanese dollar against a basket of others. Derivative traders could consider call options on these currencies to capture the upside from the export boom while limiting downside risk from any surprising Fed hawkishness. The increasing demand for high-end chips is a powerful trend that we believe will persist through the second half of the year.

This strategy is based on the widening growth differential, with US Q2 2026 growth forecasts now being trimmed towards 2.0% while key Asian economies track above 4%. Historically, we’ve seen periods where strong regional fundamentals can insulate certain currencies even during Fed tightening cycles, such as in the 2017-2018 period. We believe growth and risk sentiment are becoming more important drivers than interest rates alone.

We are also watching risk sentiment, which has been supported by Brent crude prices stabilizing in the low $80s range. This environment is particularly beneficial for net energy importers like the Indian rupee and the Philippine peso, making their currencies less vulnerable for now. Therefore, pairing longs in the tech-exporting currencies against shorts in less fundamentally supported currencies appears to be a prudent strategy in the coming weeks.
