Bitcoin (BTC) surged by 22% in the third week of August, and the upcoming monetary policy meeting of the Bank of Japan in September is expected to influence the volatility of risk assets. If expectations of a rate hike in Japan affect the cost of yen funding and dollar liquidity, BTC could also be impacted. The Bank of Japan maintained the uncollateralized overnight call rate at around 1.0% during its meeting on July 31, and member Takata Hajime advocated for a rate increase. The possibility of a rate hike will be discussed in the next meeting scheduled for September 17-18. The yield on Japan's 10-year government bonds rose to 2.945% on August 18, marking the highest level since 1996. The relationship between Bitcoin and Japanese interest rates is based on the yen carry trade, where an increase in interest rates raises the cost of yen funding, potentially increasing the volatility of risk assets. Bitcoin rose to $77,006 on August 22, reflecting a 22% increase, driven by a combination of factors including the U.S. Treasury's plan to expand its long-term bond buyback and a weakening dollar. The Bank of Japan's decisions are likely to act as background variables that could amplify volatility rather than directly impact Bitcoin prices. The market is closely watching the Bank of Japan's decision on interest rates and its future trajectory.

Bitcoin tore through the mid-$60,000s, cleared $70,000, blew past $75,000, and briefly touched $79,000+ before easing back to around $77,000 — a 20%+ move in a single week. The mood across crypto flipped almost overnight. But a violent rally is only the opening act. The more explosive the move, the more it calls for a clear, calm mind.
