Summary
On August 3, 2026, the U.S. and Japan coordinated a foreign exchange intervention to stem sharp yen weakness, causing the USD/JPY pair to reverse from nearly 164 to 156.5. U.S. Treasury Secretary Scott Bessent confirmed the intervention aimed at countering "disorderly yen movements." This move revived memories of bitcoin’s August 2024 sell-off tied to the unwinding of the yen carry trade, but current data shows bitcoin's price moves are more closely linked to U.S. dollar strength than yen fluctuations.
Why it matters
The intervention is significant because it recalls the market turmoil in 2024 when a stronger yen triggered a major bitcoin price drop. However, contrary to expectations that a rising yen would pressure bitcoin again, bitcoin's negative correlation with USD/JPY suggests the crypto asset is moving with dollar strength rather than yen moves. This challenges prior assumptions about the carry trade's impact on bitcoin.
Key context
In August 2024, the Bank of Japan (BOJ) unexpectedly raised interest rates, strengthening the yen and causing a sharp bitcoin decline of about 20%. That was due to leveraged investors unwinding yen carry trades, selling risk assets to cover losses. Last week, the BOJ held rates steady but cited AI demand and yen weakness driving inflation above 2%. The yen carry trade remains a key factor for crypto market watchers.
Key numbers and entities
The USD/JPY exchange rate fell from just below 164 to 156.5 following intervention. The BOJ currently holds rates at 1%. Bitcoin traded above $63,000 amid the intervention. U.S. Treasury Secretary Scott Bessent and BOJ Governor Kazuo Ueda are the main officials quoted. Bitcoin’s 52-week correlation with USD/JPY reached negative 0.90.
