Tokyo Two-Step: Bitcoin Boogies in Dollars, Stumbles in Yen as ¥ flexes 💴

A sharp rally in the Japanese yen is leaving major cryptocurrencies, including bitcoin ($BTC), ether ($ETH), solana ($SOL) and XRP ($XRP), underperforming in yen-denominated trading pairs even as they trade higher against the U.S. dollar. The yen climbed to 161.55 per USD from 162.42 per USD earlier on July 10, narrowing gains for digital assets quoted against the Japanese currency. On Tokyo-based BitFlyer, the BTC/JPY pair is up 0.68%, compared with a 1.15% gain in the U.S. BTC/USD reference tracked via Nasdaq. XRP/JPY, SOL/JPY and ETH/JPY show the same pattern, with each JPY-listed pair advancing less than its USD counterpart.

The move comes as renewed intervention speculation follows the yen's fall to a 40-year low earlier this week. The Bank of Japan has historically intervened by selling dollars and buying yen to support the currency, though those operations have typically produced only short-lived effects amid fiscal concerns and comparatively higher U.S. interest rates. Traders received Japan's June producer price index earlier in the session at 7.1% year over year, the fastest increase since March 2023, reinforcing expectations for further BOJ rate hikes. A former central bank official said Thursday that the BOJ may raise rates faster, potentially pushing them above 2%.

Separate from intervention concerns, Japan's government is urging the Government Pension Investment Fund (GPIF), the world's largest pension fund with roughly ¥277 trillion ($1.87 trillion) in assets, to shift more of its portfolio into domestic markets. GPIF invests heavily in global stocks and bonds, and a reallocation toward Japanese assets could ripple through global equities, fixed income and currencies. Analysts noted that the yen and bitcoin have developed an unusually strong positive correlation, often moving in lockstep against the U.S. dollar, meaning yen strength could ultimately support $BTC in dollar terms even as BTC/JPY pairs continue to lag in relative terms.
