The Japanese yen climbed sharply by 2% against the US dollar on July 30, marking its biggest daily jump since the government stepped into the market earlier this year.
This sudden move has traders on edge, especially in the crypto space where the yen plays a critical role in carry trades that fuel Bitcoin and Ethereum investments.
Speculation is rampant that Japan’s Ministry of Finance either intervened directly or is preparing to act again after massive interventions totaling about 11.73 trillion yen, or $73 billion, in April and May 2026 failed to halt the yen's slide.
Japan’s historically low interest rates made borrowing yen attractive for investors who converted it into dollars or other currencies to fund higher-yielding assets. The Bank of Japan raised its policy rate to roughly 1% in June 2026, a significant change after decades near zero. This move pushes borrowing costs higher, making leveraged positions riskier.
A stronger yen puts pressure on traders who borrowed cheap yen to buy assets like stocks, bonds, and cryptocurrencies. With funding costs rising and asset values potentially dropping, many investors may rush to unwind positions by selling off riskier holdings.
Bitcoin’s recent history shows sharp declines averaging 27% following BOJ rate hikes since 2024, signaling trouble ahead if the yen continues to gain.
The USD/JPY pair lingered around 162.3 to 162.9 in late July, levels unseen in nearly 40 years, reflecting some of the extreme yen weakness that sparked current intervention fears.
