US Treasury Secretary Scott Bessent confirmed a coordinated intervention alongside Japan to buy yen, putting real dollars behind the kind of currency activism that Washington has mostly left on the shelf since the Obama era.
The move, confirmed on August 1, involves plans to purchase between $5 billion and $10 billion in Japanese yen.
The notepad that moved markets
The intervention details first surfaced during a Camp David cabinet meeting on July 31, when Bessent’s handwritten notepad outlined the yen purchase range for cameras to capture.
Bessent’s public statement framed the action as a response to “disorderly yen movements.” The yen has been trading at levels not seen in nearly 40 years against the dollar.
The coordinated nature of the intervention is what makes it genuinely notable. Bessent confirmed active collaboration with officials from Japan’s Ministry of Finance and the Bank of Japan, meaning American dollars were deployed alongside Japanese reserves in a joint operation.
This is the first yen-buying intervention by the US in over a decade.
Why the US decided to get involved
Bessent also proposed upsizing the Federal Reserve’s FIMA Repo Facility as a complementary measure. The FIMA facility essentially allows foreign central banks to temporarily convert their US Treasury holdings into dollars. Expanding it would give institutions like the Bank of Japan more flexibility to manage liquidity without being forced into fire sales of US government debt.
What this means for crypto and risk assets
For Bitcoin specifically, the dollar dynamics matter. Active US selling of dollars to buy yen is, at the margin, dollar-negative. A weaker dollar has historically correlated with stronger Bitcoin performance, since BTC is priced in dollars and becomes relatively cheaper for international buyers when the greenback softens.
Traders should also watch the FIMA Repo Facility expansion closely. If foreign central banks gain more flexibility to access dollar liquidity without selling Treasuries, it reduces the risk of disorderly moves in US bond markets.
