Arthur Hayes Says Fed’s Japan Yen Plan Will Pump Bitcoin

Arthur Hayes says a Fed plan to help Japan defend the yen will print new dollar liquidity, and he argues that liquidity will pump Bitcoin (BTC).

Hayes co-founded BitMEX and now runs the Maelstrom family office. He has built a reputation for macro calls that tie Fed and Treasury policy moves directly to crypto prices.

How A Yen Rescue Becomes Dollar Liquidity

The mechanism he describes is real, though its scale is not yet confirmed. It runs through the Foreign and International Monetary Authorities (FIMA) Repo Facility, a Fed program that lets foreign governments post US Treasuries as collateral for short-term dollar loans, instead of selling those Treasuries outright.

Treasury Secretary Scott Bessent has said Japan holds $1.143 trillion in US Treasuries. Under Hayes' scenario, Tokyo repos part of that stockpile for dollars, sells the dollars for yen, and reinvests the yen into domestic bonds and stocks.

The Fed's balance sheet grows to fund each loan, which is functionally similar to printing money, though the Fed frames it as a lending facility rather than quantitative easing (QE).

Hayes' bet is that these dollars do not stay contained. BTC, in his view, is one of the most liquidity-sensitive assets in the market.
