Most Asian currencies eased on Monday as a stronger U.S. dollar and higher U.S. Treasury yields put pressure on regional foreign exchange markets. The Japanese yen, however, attracted particular attention after renewed speculation that Japan's large public pension fund might increase its holdings of domestic assets, a scenario market participants said could lend support to the currency.
Geopolitical developments also fed market uncertainty. Fresh U.S.-Iranian missile exchanges and Tehran's renewed assertion that it had closed the Strait of Hormuz cast doubt over last month's agreement to restore shipping through the strategic oil chokepoint, adding to risk-off dynamics that tended to favor the dollar.
Market expectations for U.S. monetary policy shifted as investors priced in a lower probability of near-term Federal Reserve easing. The dollar strengthened on concerns that inflation could remain elevated, prompting traders to pare back bets on policy loosening ahead of Federal Reserve Chair Kevin Warsh's first congressional testimony and the U.S. inflation report due on Tuesday.
Yen outlook brightens despite broader dollar gains
The yen remained under close observation after a sharp rebound on Friday following remarks from Japanese Finance Minister Satsuki Katayama. Katayama said she wanted to encourage public pension funds, including the Government Pension Investment Fund (GPIF), to invest more in Japanese financial assets. Those comments prompted speculation that GPIF, one of the world's largest institutional investors, could gradually shift some overseas holdings back into domestic assets.
That potential reallocation is viewed by some market participants as a structural source of support for the yen, which has faced sustained pressure over the past year. The USD/JPY pair rose about 0.2% to 162.1 on Monday, recovering part of Friday's decline but remaining well below last week's peak near 162.7, a level that had previously stoked fears of renewed market intervention.
Tony Sycamore, a market analyst at IG, said that if Katayama's remarks led to concrete changes in pension fund allocations, the impact could be substantial. He estimated an initial move might generate approximately JPY12 trillion of yen buying, while a more aggressive rebalancing could bring flows as large as JPY30 trillion, amounts that Sycamore said would provide meaningful support for the currency.
Separately, Reuters reported that the Bank of Japan is considering raising its fiscal 2026 growth forecast later this month while continuing to point to upside inflation risks. The report said policymakers view the inflation upsides as coming from a weaker yen and resilient investment related to artificial intelligence, which could offset lower energy costs.
Dollar-driven weakness across regional currencies
Beyond Japan, a broadly firmer U.S. dollar and rising Treasury yields encouraged investors to scale back exposure to Asian assets, putting downward pressure on local currencies. The USD/KRW climbed roughly 0.6% to trade above 1,507, while USD/TWD remained elevated as continued foreign selling of technology shares weighed on both currencies.
A trading curb was imposed briefly on South Korea's KOSPI after the index registered a drop of more than 5% earlier in the session, reflecting the impact of equity market stress on currency dynamics. The Australian dollar also weakened, with USD/AUD rising about 0.4%.
China's onshore and offshore yuan showed relative resilience. Both USD/CNY and offshore USD/CNH edged only modestly higher as investors awaited a busy week of domestic data releases.
Markets look to a packed economic calendar
Investors are turning their attention to a string of Asian economic releases. China's June trade data is due on Tuesday, followed later in the week by second-quarter GDP, retail sales and industrial production figures. Singapore will publish an advance estimate of second-quarter GDP, and markets will also be watching for the Bank of Korea's policy decision. These data points and policy events could influence local currency moves and investor positioning in the coming days.
Against this backdrop, monetary policy expectations, geopolitical developments and potential pension fund portfolio shifts remain the dominant themes shaping currency flows across the region.
