Asian Currencies Weaken on Dollar Strength; Yen Supported by Pension Fund Repatriation Hopes

Most Asian currencies weakened on Monday as a firming U.S. dollar and rising Treasury yields pressured regional foreign exchange markets. The Japanese yen, however, was a key focus, showing relative resilience amid renewed speculation that Japan's giant public pension fund could begin shifting investments back into domestic assets.

Yen in Focus on Repatriation Hopes

The yen drew support following remarks from Japanese Finance Minister Satsuki Katayama, who stated she wanted to encourage public pension funds to invest more in Japanese financial assets. This sparked speculation that the Government Pension Investment Fund (GPIF), one of the world's largest institutional investors, could start repatriating a portion of its vast overseas holdings.

Such a move could create a significant and structural source of demand for the Japanese currency.

• Potential Impact: Tony Sycamore, a market analyst at IG, estimated that a gradual portfolio shift could generate approximately JPY 12 trillion in yen buying, with a more aggressive rebalancing potentially reaching JPY 30 trillion.

The USD/JPY pair traded around 162.1, recovering slightly from a sharp decline on Friday but remaining below last week's highs. Adding to the sentiment, Reuters reported that the Bank of Japan is considering raising its fiscal 2026 growth forecast, citing a weaker yen and resilient AI-related investment.

Broad Dollar Strength Pressures Regional FX

Elsewhere in Asia, currencies broadly declined as the U.S. dollar strengthened. The move was driven by investors trimming expectations for Federal Reserve policy easing amid concerns that U.S. inflation could remain elevated. Higher Treasury yields and geopolitical tensions in the Middle East further supported the greenback.

The South Korean won and Taiwan dollar were notably weaker, weighed down by continued foreign selling of technology shares. The USD/KRW pair climbed about 0.6% to over 1,507. In South Korea, a brief trading curb was imposed on the KOSPI index after it fell more than 5%. The Australian dollar also softened, with the USD/AUD pair rising approximately 0.4%.

Key Data Ahead

Investors are now looking ahead to a week packed with key economic data and events. In the U.S., focus will be on upcoming congressional testimony from the Federal Reserve Chair and crucial inflation data. Regionally, markets await a series of releases from China, including June trade data, second-quarter GDP, retail sales, and industrial production, as well as a policy decision from the Bank of Korea.
