Korean Won Leads Asian FX Gains on Tech Stock Support - MUFG

A softer dollar combined with resilient semiconductor exports is driving the Korean won to become the front-runner in Asian FX markets recently. Lloyd Chan, analyst at Mitsubishi UFJ Financial Group, noted that the won is outperforming regional peers, benefiting mainly from the semiconductor and AI investment cycle that supports exports and capital inflows. The dollar-won pair is currently trading around 1393.03, after the won earlier broke above the 1400 level and returned to the 1300 range for the first time in nearly ten months, highlighting the direct boost to the currency from tech stock inflows.

**Tech cycle supports exports and capital inflows**

South Korea, as a core player in the global semiconductor supply chain, is benefiting from AI-driven expansion in chip demand. Lloyd Chan emphasized that the resilience of this investment cycle not only supports South Korea's export outlook but also attracts sustained foreign inflows into Korean equities. Earlier, the KOSPI index surged 5.89% in a single day, reflecting market optimism toward heavyweight tech stocks. Against this backdrop, the won's sensitivity to dollar weakness has been amplified, allowing it to record relatively stronger gains among Asian currencies.

**Yen linkage and derivatives opportunities**

MUFG's analytical framework shows that the yen is becoming a core driving variable in Asian FX markets. If the yen continues its strength, the won is expected to be one of the biggest beneficiaries, as its beta to yen volatility has risen against the trend since 2025, while correlation coefficients for most other Asian currencies have trended lower. This divergence creates trading opportunities in the FX derivatives market, with investors able to watch for changes in volatility on won cross pairs.

**Risk factors remain to watch**

Despite support from the tech cycle, the won's trajectory still faces external uncertainties. The US 10-year Treasury yield recently broke above 4.7%, approaching the psychological 5% level, and a high-rate environment could curb tech stock valuation expansion, thereby weakening foreign inflow momentum. Additionally, if Middle East geopolitical tensions escalate further, they could also disrupt the won through the risk-appetite channel. Going forward, attention should be paid to Federal Reserve policy signals and changes in global semiconductor demand.
