According to ChainCatcher, citing CoinDesk, bitcoin traders need to watch the Bank of Japan’s interest-rate decision scheduled for Tuesday this week. In the week ended June 9, speculative short positions in the yen held by leveraged funds increased to more than 115,000 contracts, the highest level since November 2017. The size of that position has brought the yen, and the liquidity conditions tied to yen-funded trades, back into focus for crypto-market participants.
BOJ Decision Meets Crowded Yen Shorts
If the Bank of Japan raises rates to 1% as expected and signals further tightening, those yen short positions could be forced to close. Such short covering would push the yen higher and pressure yen-funded carry trades. In these trades, investors borrow yen and allocate capital to higher-yielding risk assets. CoinDesk noted that this structure has supported bull markets on Wall Street and in bonds for years, and has also been viewed as a support for the crypto market.
The July 2024 Move Remains a Reference Point
The report also referred to the Bank of Japan’s rate increase in July 2024. After that move, yen shorts were rapidly closed, triggering a sharp rally in the yen. Wall Street, the Nikkei index and the crypto market then experienced severe volatility, while bitcoin fell from around $65,000 to $50,000 within one week. That episode is being used as a reference for how a disruption in yen carry trades can affect risk assets, including digital assets.
After this week’s decision, comments from Bank of Japan Governor Kazuo Ueda will also be part of the focus. If Ueda indicates faster tightening, or a path in which rates rise above 1%, the yen would strengthen sharply and financial markets would face turbulence. CoinDesk’s report stated that crypto assets are the most sensitive to sudden changes in liquidity, and therefore could suffer the heaviest impact under such conditions.
