Japan’s Finance Minister Satsuki Katayama has confirmed ongoing collaboration with the US Treasury to stabilize the yen, which recently hit a four-decade low near 160 162 yen per dollar. This partnership signals a serious response to the currency’s sharp decline.
Katayama’s warnings started months ago, with a promise of “decisive action” if the yen stayed weak in April. By late June, authorities were ready to intervene once the exchange rate slipped beyond 161. Japan has already spent roughly $63.5 billion trying to prop up the yen, reflecting high stakes for Tokyo’s economic stability.
The coordination with the US intensified after a May meeting between Katayama and Treasury Secretary Scott Bessent. Officials keep constant communication following a September 2025 agreement focused on foreign exchange cooperation. Katayama emphasized readiness to act "at any time" should the currency’s slide continue.
Japanese Companies Pivot to Crypto Amid Yen Weakness
Amid the yen’s instability, many Japanese businesses seek refuge by diversifying treasury assets through cryptocurrencies. SBI VC Trade, one of Japan’s leading crypto exchanges, reported over 2 million corporate accounts as of early July 2026. Bitcoin and XRP stand out as preferred assets, offering an alternative to traditional holdings.
The yen’s prolonged weakness fuels the infamous carry trade: borrowing cheap yen to invest in higher-yield currencies or risk assets. However, sudden yen strength can trigger swift market turmoil, as seen in the 2024 carry trade unwind when the Bank of Japan unexpectedly raised rates. The ripple effects hit global stocks and even Bitcoin.
This ongoing currency drama means investors should watch closely how Tokyo and Washington manage intervention efforts and how Japanese firms’ crypto adoption might reshape treasury strategies.
