Arthur Hayes said on X that his upcoming essay, "Yen-quake," will examine what he described as a plan by "Buffalo Bill Bessent" to influence the U.S. dollar-Japanese yen exchange rate and restart the monetary printing press. Hayes argued that the yen’s long decline over the past decade helped push global asset markets higher, but said that phase will eventually end. He outlined three ways the yen could strengthen. The first is a sharp Bank of Japan rate hike that would at least erase the short-end rate gap between the dollar and yen. The second is for the government to persuade domestic institutions and public bodies such as GPIF to change their investment mandates, sell overseas assets, and buy local assets. The third, which Hayes called the preferred route, would see Japan’s Ministry of Finance hand its U.S. Treasury holdings to the Federal Reserve through repo transactions in exchange for dollars, then sell those dollars and buy yen in the foreign-exchange market. Hayes also pointed to what he called a joint intervention by U.S. and Japanese monetary officials two weeks ago, and cited comments from U.S. Treasury Secretary Buffalo Bill Bessent on raising FIMA repo counterparty limits. He added that if dollar liquidity rises sharply, Bitcoin and the broader crypto market will move higher.

Former Bank of Japan board member Atsushi Takeuchi said Japan and the United States would “definitely” carry out another joint market intervention if the yen shows signs of renewed weakness, according to Jin10. He said the latest coordinated action by Tokyo and Washington was highly effective, helping shape a market consensus that the yen is unlikely to keep weakening in a one-way move. Takeuchi also said the dollar-yen exchange rate could trade in a range of 155 to 162 in the near term. The remarks point to continued market attention on official policy signals and the response of Japanese authorities if the currency comes under pressure again.

Japanese officials said Tokyo coordinated with the US Treasury to buy yen, and both President Donald Trump and Treasury Secretary Scott Bessent later confirmed US participation while leaving the door open to another joint operation. After those statements, USD/JPY pulled back sharply from levels near 164 seen last week, at one point falling to around 155.20, while an Associated Press reading on the morning of Aug. 3 showed the pair near 156.34. A Reuters photograph taken on July 31 added another layer to the story. Bessent’s notepad at a Camp David cabinet meeting included the line: "To Do: Buy Japanese Yen (JPY) $5-10 bil." That note does not confirm how much was actually bought, and the US Treasury had not formally verified a figure at the time. Even so, the image suggested Washington had considered a purchase large enough to matter to leveraged traders. The intervention has changed the risk profile of yen-funded carry trades rather than erased the strategy outright. The Federal Reserve kept its federal funds target range at 3.50% to 3.75% on July 29, while the Bank of Japan left its short-term policy rate at 1% on July 31. Japan’s financing choices also matter for global markets: Bessent said the Federal Reserve’s FIMA repo facility was used in the operation, a mechanism that can provide dollar liquidity against Treasuries without requiring immediate outright sales.

JPMorgan strategists said the US Treasury’s readily available resources for foreign-exchange intervention are limited, but the pool could expand sharply under less conventional funding arrangements. In an Aug. 3 note, the bank said the Treasury’s Exchange Stabilization Fund held roughly €13 billion in euro-denominated assets and $25.5 billion in dollar assets as of June. That amount looks modest next to Japan’s intervention size of about $35 billion to $60 billion between 2022 and 2026. The report laid out two ways to increase intervention capacity: converting the Treasury’s IMF Special Drawing Rights into dollars, and swapping foreign-currency assets into dollars. Under that framework, JPMorgan said the Treasury could theoretically mobilize as much as $187 billion. If the Federal Reserve were involved, the scale of intervention could be "effectively doubled," implying a potential US-Japan pool of $374 billion. The strategists also warned that intervention capacity is not unlimited because the Exchange Stabilization Fund is finite and fresh funding may require congressional appropriations. The report came after the US Treasury, through the Federal Reserve Bank of New York and via Goldman Sachs and JPMorgan, bought yen last Friday in what it described as the first coordinated intervention with Tokyo in more than a decade.

BlockBeats reported on Aug. 3 that USD/JPY extended its decline by 170 points within 15 minutes, marking the first break below the 156 level since May 6. The pair was down more than 1% on the day. Earlier, both the United States and Japan had said they would not hesitate to further coordinate and carry out intervention in the foreign exchange market. The move put the 156 threshold back in focus after the pair slipped through the level in a rapid intraday drop. The report tied the latest price action to prior remarks from the U.S. and Japan that they were prepared to step up joint action in the currency market if needed.
