Japan's 2-Year Bond Yield Reaches 31-Year High, Impacting Yen Carry Trade and Bitcoin

Japan's two-year government bond yield climbed to 1.746% on Monday, marking its highest level in more than 31 years. This increase raises the cost of the yen carry trade, a strategy that has been instrumental in funding global risk assets, including Bitcoin (BTC).

The rise in yields reflects traders' expectations regarding the Bank of Japan's (BOJ) monetary policy, with swap markets indicating an 88% probability of a rate hike in September. The BOJ raised its policy rate to 1% in June, the highest since 1995, leading to a corresponding increase in longer maturities, with the 10-year Japanese government bond yield now at approximately 2.93%.

Despite these higher rates, the yen has continued to weaken, trading at 160.16 per dollar on Friday and touching 160.20 again on Monday. The Japanese government has intervened significantly, deploying 15.4 trillion yen (around $97 billion) between late July and late August, including a rare joint intervention with the United States.

However, the yen has lost more than half of the gains achieved from this intervention. The spread between U.S. and Japanese two-year yields has narrowed to 2.64%, down from nearly 5% at the peak in 2023 and 2024, indicating a diminishing incentive for borrowing yen.

This divergence suggests that factors beyond interest rates are influencing the yen's performance. The mounting losses in Japanese bonds and heavy debt issuance indicate a lack of confidence that higher rates alone cannot address.

For Bitcoin, the implications of the yen carry trade are significant. Investors often borrow yen at low rates to invest in higher-yielding assets abroad. A sharp appreciation of the yen can make these loans more expensive to repay, potentially leading to forced selling of assets like Bitcoin. This was evident in August 2024 when Bitcoin and Ethereum experienced losses of up to 20% as yen-funded positions were unwound.

Currently, Bitcoin is trading at $79,087, reflecting a 1.3% increase over the past 24 hours, after having dipped below $77,000 last week due to hawkish comments from Federal Reserve chair Kevin Warsh. The upcoming BOJ decision in September is seen as a marker rather than a shock, as the anticipated move has largely been priced in, while the unwinding of positions continues to build.
