Japan's Yen Intervention Boosts Carry Trade Opportunities

August 21, 2026Carlos Mendoza3 мин

Japan's significant efforts to support the yen may have produced an unexpected outcome: providing certain investors with enhanced opportunities to increase their carry trade activities.

Data from the Ministry of Finance indicates that Japanese investors purchased over 5 trillion yen in foreign equities and long-term bonds in the two weeks ending August 15th. This contrasts with a net selling of over 300 billion yen in the preceding two weeks.

Market analysts suggest that investors capitalized on the yen's rapid appreciation following the recent joint U.S.-Japan currency intervention, allowing them to acquire overseas assets at more advantageous exchange rates.

"Intervention has 'turbo-charged' the carry trade for fundamental and long-term investors," stated Jesper Koll, expert director at Monex Group. "As long as the cost of money in Japan remains lower than the returns available overseas, carry trades will re-establish themselves," Koll added.

Although authorities managed to lift the yen, their actions had minimal impact on reducing the incentive for investors to borrow cheaply in Japan and invest in higher-yielding assets abroad.

The yen briefly strengthened from approximately 164 per dollar before the intervention to around 155, but it quickly relinquished a substantial portion of these gains, now trading back near 159 against the dollar.

This trend reinforces expectations that the yen will likely remain under pressure unless the Bank of Japan implements interest rate hikes substantial enough to significantly narrow the bond yield gap with the U.S. As of Thursday, the 10-year U.S.-Japan yield spread stood at approximately 1.8 percentage points.

The brief surge in the yen suggests that investors view periods of yen strength as chances to rebuild carry trade positions rather than abandoning them.

This dynamic is particularly evident among Japanese institutional investors. According to Masahiko Loo, fixed income strategist at State Street Global Advisors, long-term investors like pension funds and asset managers have continued to sell yen.

"The intervention only addressed a 'symptom,' but is not curing the 'disease'," commented Francis Tan, Asia chief strategist at Indosuez Wealth Management. He was referring to underlying structural factors such as Japan's low borrowing costs and the wide interest-rate differentials with other major economies.

Koll also noted that Japanese retail and institutional investors have utilized the stronger yen to establish new positions in non-yen denominated assets, particularly in higher-yielding U.S. bills and bonds.

"The market is far less one-sided than before the intervention, but the incentives to fund in yen remain attractive while U.S.-Japan rate differentials stay wide," Loo observed.

Additional flow data further support the continuation of carry trades. Masahiko Loo of State Street Global Advisors indicated that long-term investors continue to sell low-yielding yen in favor of higher-yielding G10 currencies, which is consistent with investors using the Japanese currency to fund positions elsewhere.

Ashwin Binwani, founder of Alpha Binwani Capital, stated that institutional investors have maintained their positions in carry trades against a group of G10 currencies, with the Australian dollar being a primary focus.

There are also indications that some currency traders are re-establishing bearish bets against the yen as the impact of the intervention diminishes.

Binwani closed his long dollar-yen positions after the U.S.-backed intervention, only to re-establish them slightly above 157, anticipating further yen depreciation. "Upon news of the U.S. intervention, we took profit and once again re-established dollar yen long positions just slightly above 157," he reported.

Binwani suggested that each intervention-induced rally could potentially offer investors a more favorable entry point to sell the currency. While distinct from borrowing yen to directly invest in higher-yielding assets, this strategy is underpinned by the same fundamental driver: Japan's persistently low interest rates that keep its currency under pressure.

However, overall speculative positions against the yen have decreased. CFTC data reveals that leveraged funds significantly reduced their net short yen positions from nearly 138,000 contracts at the end of June to 59,526 as of August 11th, following demonstrated willingness of authorities to intervene.
