Bitcoin's 21% Weekly Rally Faces Risk From Japan Rate Decision

Bitcoin was trading near $77,200 at the time of writing, having surged more than 21% over the previous seven days. Market sentiment has turned bullish, with the Crypto Fear and Greed Index reaching 73, deep in greed territory. The index itself jumped 16 points in a single day on August 20th as Bitcoin broke above $72,000.

The rally has drawn attention to technical signals suggesting caution. The relative strength index sits in overbought territory, indicating a potential pullback may follow.

The primary near-term risk stems from the Bank of Japan's policy meeting scheduled for September 18th. Markets have sharply increased bets on a rate hike, with overnight-index swaps pricing in around an 82% probability, up from roughly 23% before the BOJ's surprise July increase. That earlier move triggered a sharp global market selloff. Senior economist Kento Minami at Daiwa Securities noted that BOJ officials are likely to signal the need for an early hike by emphasizing upside inflation risks, which traders may interpret as confirmation of a September move.

The immediate impact on bitcoin and the broader crypto market could be negative if rates rise. However, with the yen trading near 160 per dollar, the BOJ has some room to communicate a dovish tone without risking further currency depreciation. Japan's 10-year government bond yield has already risen to around 2.95%, the highest since 1996, as investors shift away from the low-yielding assets that have long characterized Japanese markets. Rising Japanese yields could reduce demand from domestic investors for foreign assets, potentially affecting global markets and cryptocurrencies.
