US-Japan Yen Intervention Raises Questions for Bitcoin and Risk Assets

The United States and Japan carried out their first joint intervention in the yen since the late 1990s, stepping in after the currency slid to a forty-year low of 164 per dollar. Rather than selling dollars directly, the New York Fed sold euros on behalf of the US Treasury, drawing on the Exchange Stabilization Fund’s foreign currency reserves.

Treasury Secretary Signals Deeper Coordination

Following the intervention, Treasury Secretary Scott Bessent emphasized plans to meet with Bank of Japan Governor Kazuo Ueda at the upcoming G20 finance ministers’ gathering in North Carolina later this month. He praised Japan’s economic performance and pointed to strong coordination between the two nations, while also calling for an expansion of the FIMA repo facility, a tool that lets foreign central banks access dollar liquidity using Treasury holdings as collateral without needing to sell them outright.

Bitcoin’s Potential Link to the Yen Carry Trade Unwind

Within crypto markets, some observers see a possible upside for Bitcoin tied to the unraveling of the yen carry trade, a long-standing strategy where investors borrowed cheaply in yen to fund purchases of higher-yielding assets elsewhere. Japanese two-year bond yields climbed above 1.50% on Monday, signaling that the era of ultra-low rates may be ending faster than markets expected.

Rising domestic yields, driven partly by heavy government spending, are making yen-funded trades less attractive and encouraging Japanese investors to repatriate capital, a shift that could further destabilize the carry trade and, by extension, influence liquidity conditions for Bitcoin and other risk assets.
