US Euro Sale Pushes Yen to 158, Raising Bitcoin Macro Risk

Crypto News

Bitcoin (BTC), trading near $64K, is facing a fresh macro test after the US Treasury sold euro reserves rather than dollars to support Japan’s currency last week. The operation, executed by the New York Federal Reserve on behalf of the Treasury, was disclosed to the European Central Bank only after the trade had closed. ECB President Christine Lagarde and Treasury Secretary Scott Bessent spoke about the move a day later, highlighting a break from the post-World War II practice of coordinating major currency interventions. Officials chose euros deliberately because selling dollars could have signaled a retreat from Bessent’s strong-dollar stance, so the Exchange Stabilization Fund used euro assets instead. Analysts noted that the yen carry trade, a strategy built on borrowing cheaply in Japan and seeking higher yields elsewhere, may be losing effectiveness. Some economists also linked the intervention to concern that Tokyo might respond by selling US government debt. The episode also revived debate about reserve-policy coordination among allies. The action moved the Japanese currency from around ¥164 to close to ¥158 per dollar, while Japanese equities absorbed the shock with limited losses. For crypto desks, the key channel is liquidity: reserve operations and currency-policy signals can shift risk appetite across Bitcoin and the broader altcoin market quickly for macro-sensitive traders.

Former Federal Reserve Vice Chair Roger Ferguson added a hawkish layer to the backdrop on August 6, saying he does not expect three US rate increases but leaves open the possibility of two by early next year. Ferguson argued that inflation moving just below 3% is different from reaching the Fed’s 2% target, meaning progress in housing, services and wages is not yet sufficient to declare victory. He pointed to oil prices and potential supply disruptions as reasons the disinflation path could stall, while also urging clearer central-bank communication. In his view, markets do not need absolute rate promises, but they do need a better explanation of how policymakers will react to incoming data, including the use of the dot plot. Ferguson also drew a line around institutional roles: monetary policy belongs to the Fed, while fiscal policy and dollar policy belong to the Treasury. He said conversations between the president and the Fed chair can be routine, but direct political demands for rate changes would cross an acceptable boundary. With Fed Chair Kevin Warsh facing criticism from the current administration, Ferguson said the central bank must demonstrate independence. For crypto, the risk is that higher-for-longer rates strengthen the dollar and pressure speculative assets, especially when Bitcoin remains far from its prior all-time-high cycle peaks.

The diplomatic aftermath may matter as much as the transaction itself. Senior ECB officials described the episode as a departure from decades of Western coordination, and one person familiar with the discussions called it unprecedented. A Treasury spokesperson defended the operation, saying decisions over the Exchange Stabilization Fund are made by the Treasury after considering market liquidity, valuations and other relevant factors alongside the Federal Reserve. A senior Trump administration official rejected criticism, arguing that Washington respects confidentiality with foreign counterparts and contrasting its handling with the ECB’s public posture. It also raises questions about reserve asset usage and whether future operations could tap other currencies. The next question is whether this was a one-off intervention or a preview of how the administration will manage currency defense with allies. In Japan, traders are already positioning for a potentially tighter policy path: markets assign a 44% probability to a Bank of Japan rate increase in September, after June minutes showed policymakers debating mounting price risks. Governor Kazuo Ueda has highlighted inflation risks as a reason for caution. A stronger yen and higher Japanese rates can reduce yen-funded leverage, a channel that often affects global risk assets. That transmission can reach crypto through liquidity, margin behavior and stablecoin settlement rails, including algorithmic stablecoins, even when the original intervention is aimed at traditional foreign-exchange markets.
