BitMEX co-founder Arthur Hayes said coordinated efforts by the U.S. and Japan to strengthen the yen could expand dollar liquidity and help drive a rally in Bitcoin.
In a Substack post titled "Yen-quake" published on August 10, Hayes wrote that Washington and Tokyo had begun working together to lift the yen's value, a process that could sharply increase dollar liquidity.
He outlined three ways to push the yen higher: aggressive rate hikes by the Bank of Japan; a shift by the Japanese government away from overseas assets and toward domestic investment; and a plan under which Japan's Ministry of Finance would use U.S. Treasuries as collateral to access the Federal Reserve's FIMA Repo Facility, obtain dollars, sell them and buy yen.
