Bitcoin surged past the $74,000 mark on Monday, driven by developments in Japan’s monetary policy. Bank of Japan Governor Kazuo Ueda’s decision to temper expectations for an imminent interest rate hike at the upcoming April 28 policy meeting has injected a sense of caution into financial markets. This comes amid ongoing uncertainty regarding the implications of the Iran war and its potential impact on Japan’s economy.
Historically, policies set by the Bank of Japan (BOJ) have had significant repercussions for the cryptocurrency market. A notable example occurred on August 5, 2024, when an unexpected rate hike by the BOJ led to a swift liquidation of yen carry trades, resulting in a dramatic drop in bitcoin’s value from $64,000 to $49,000 within 48 hours. This carry trade mechanism, where investors borrow at low rates in yen to invest in higher-yielding assets like cryptocurrencies, has become one of the primary drivers of leveraged investment globally. An unwind of this trade typically leads to immediate sell-offs in riskier assets, including bitcoin and other major cryptocurrencies.
Governor Ueda’s recent comments indicate that such a scenario will not occur in the near term, allowing the carry trade to remain in place. This sentiment was bolstered by Tuesday’s 20-year bond auction in Japan, which saw the highest demand since 2019. The auction reported a bid-to-cover ratio of 4.82, significantly exceeding the 12-month average of 3.27, underscoring institutional confidence in a prolonged pause in the BOJ’s hiking cycle. Following the auction, yields on 20-year bonds, which are near their highest levels since 1997, dropped by nine basis points.
Maintaining a dovish stance keeps the yen weak, now trading near 160 to the dollar. A weaker yen continues to facilitate cheap funding for carry trades, sustaining leveraged positions across various risk assets, including bitcoin. Recent data indicates substantial movements in the perpetual futures markets, with $2.1 billion in new bitcoin open interest and an additional $2.2 billion in ether open interest recorded within 24 hours following a recent ceasefire. This suggests that part of this positioning may be supported by the same yen liquidity that Ueda’s remarks have preserved.
Moreover, Japan’s economic structure makes it particularly vulnerable to geopolitical developments in the Strait of Hormuz, a critical route for over 90% of its oil imports. Should negotiations between the U.S. and Iran result in a favorable agreement, further declines in oil prices could alleviate inflationary pressures in Japan, providing even less rationale for the BOJ to initiate rate hikes. This scenario would extend the timeframe during which the carry trade can bolster risk assets, including cryptocurrencies.
As a result, the BOJ’s hesitance has emerged as a crucial factor fueling bitcoin’s recent breakout. The resistance level at $73,000 had held firm for six weeks, primarily due to macroeconomic challenges posed by fluctuating oil prices, interest rates, and geopolitical tensions. With these constraints now appearing less formidable, leveraged traders are finding renewed motivation to drive the cryptocurrency higher.
