Japan's rate shock deepened on Tuesday with 30-year government bond yields approaching their all-time high of 4.205%, last tested in May, while 10-year yields reached 3% for the first time since 1996. The rate hike itself was never the surprise, as markets had nearly fully priced a September move, but what nobody saw coming was US Treasury Secretary Scott Bessent publicly demanding it at the G20 finance gathering in Asheville, North Carolina. Bessent met with Finance Minister Satsuki Katayama and Bank of Japan Governor Kazuo Ueda, pressuring for hikes and a clearer fiscal plan, stating he had information that the market doesn't have. Japan's whole curve gave way, with the two-year hitting a 31-year high, lifting yen carry trade costs that had been near zero for a generation. Other long-end markets moved with it, with UK 10-year gilts reaching 5.23%, a level last seen in 2008, US 10-year Treasuries trading at 4.78%, and Brent crude climbing above $92 a barrel.
Bitcoin traded at $79,041 on Tuesday, remaining relatively resilient despite the intensified macroeconomic pressures from Japan's rate shock. The cryptocurrency gained 1.30% over 24 hours, showing strength as traders avoided aggressive profit booking following August's strong rally. According to The Economic Times, Bitcoin's implied volatility index has eased to around 37.5 from the previous 43-46 range, suggesting markets are digesting August's gains rather than entering a broad-based risk-off phase. The broader crypto market showed mixed performance, with Ethereum rising 1.71% to $2,477, while major altcoins like BNB, XRP, Solana, Hyperliquid, Dogecoin and Cardano gained up to 4.26%, though Tron declined 1.41%. The global crypto market capitalisation was up 1.01% to $2.657 trillion, with the fear and greed index slightly rising to 75 as market sentiments remain greedy.
Japan's two-year government bond yield climbed to 1.746% on Monday, marking its highest level in more than 31 years. The move raises the cost of the yen carry trade that has helped fund global risk assets, including Bitcoin. Swap markets now price roughly 88% odds of a rate increase in September, with the BOJ having lifted its policy rate to 1% in June, the highest since 1995. Tokyo deployed 15.4 trillion yen, close to $97 billion, between July 30 and August 26, including a rare joint intervention with the United States on July 31. However, the currency has already surrendered more than half of those gains, with the spread between US and Japanese two-year yields narrowing to 2.64% from its 2023 and 2024 peak of close to 5%. The Bank for International Settlements put yen loans to non-banks outside Japan near $250 billion in March 2024, with cross-border yen claims on offshore centers around $500 billion. When it happened, Bitcoin and Ethereum shed up to 20% during the August 2024 unwind as margin calls forced traders to liquidate positions across asset classes.
The U.S. strike on Iran's Larak Island added another macro risk alongside yen weakness and higher rate expectations. Reuters reported that U.S. forces struck Iran's Larak Island on Sunday and that oil rose as Gulf tensions flared. The report revealed that flows of crude and refined products through the Strait of Hormuz, which averaged about 18 million barrels per day before the conflict, fell to 4.8 million bpd in July and averaged around 2 million bpd so far in August, according to Kpler. The report said traders were increasingly treating disruptions to Middle East energy supplies as a new reality rather than a temporary shock. Bitcoin's stability during this geopolitical escalation showed it did not trigger the immediate sell-off seen during earlier risk events, though this does not establish Bitcoin as a permanent geopolitical hedge.
Monday was the final trading session of August, with the month's closing ETF total showing whether an eight-day bitcoin ETF inflow run survived the change in rate expectations or ended with it. US-domiciled digital-asset ETFs recorded $2.36 billion of net inflows last week, their strongest week since early October 2025. Bitcoin-focused products alone attracted $537 million on August 20 and another $659 million on August 21. However, U.S. spot Bitcoin ETFs recorded an estimated $201.9 million in net outflows on August 28, suggesting ETF demand should not be described as uninterrupted. Investors were turning to upcoming U.S. data, including the nonfarm payrolls report and consumer inflation figures, which could shape expectations ahead of the September Fed meeting. Over the past week, Bitcoin and Ethereum were down 2.06% and 1.24% respectively, with major altcoins like BNB, XRP, Tron, Dogecoin, and Cardano correcting up to 11.03%, while Solana and Hyperliquid were up 1.77% and 3.87% respectively.
Analysts expect Bitcoin to consolidate around $78,000-$79,000 after ending August with a strong 25% gain, but the macro backdrop is becoming less supportive. Nischal Shetty from WazirX noted that Bitcoin trades near $78,405, retaining a positive daily bias despite RSI around 71, while CoinSwitch Markets Desk suggests a clean break above $80,000 would strengthen near-term momentum. Avinash Shekhar from Pi42 advises investors to avoid chasing sharp price moves and instead look for confirmation around key support and resistance zones, with staggered entries during pullbacks and disciplined position sizing. Prateek Gupta from Mudrex noted that Fed Chair Kevin Warsh's comments have encouraged some profit-taking, while Vikram Subburaj from Giottus emphasized that institutional demand remains positive overall despite moderated momentum. The cryptocurrency's seven-day gains still run near 9.7% despite recent pullbacks, with resistance stacked at $81,121 first, then a heavier shelf at $82,500–$84,700. The BOJ decides on September 18, with markets pricing a quarter-point move to 1.25%, and Ueda's guidance on what follows may matter more to crypto than the hike itself.
