Bitcoin surged to $88,000 on Friday after the Bank of Japan raised interest rates to their highest level in 30 years—a move that failed to trigger the expected risk-off response or drive investors into the yen.
Crypto markets remained volatile, with bitcoin bouncing from an early low of $85,200 around 1:00 a.m. UTC to $88,000 over five hours. This marked the fourth time this week that bitcoin rose more than 2%, although each rally was short-lived, reflecting the choppy price action typical of previous crypto bear markets.
Traditional markets showed little disruption. Nasdaq 100 futures climbed 0.62% during the same window, while the yen weakened, indicating that the rate hike was largely priced in and that investors were not fleeing risk assets.
A BOJ rate increase is usually viewed as bearish for risk assets because higher Japanese borrowing costs can trigger the unwinding of yen-funded carry trades, where investors borrow low-cost yen to invest in higher-yielding assets such as U.S. equities, bonds, and cryptocurrencies. However, that dynamic did not materialize Friday.
Derivatives activity
Bitcoin’s derivatives market suggested the move was driven by fresh leveraged long positions rather than short-covering. Open interest rose faster than price, while the aggregate funding rate across exchanges climbed to 0.085%, the highest since Nov. 21, according to Coinalyze. Positive funding rates indicate bullish sentiment, as traders holding long positions pay interest to those holding shorts. Bitcoin’s long-to-short ratio also skewed bullish, with 66% of traders positioned long over the past four hours.
Altcoin derivatives showed weaker activity. Open interest in Solana and XRP dropped 4.4% and 2.6%, respectively, despite minimal price changes, suggesting traders are reducing exposure to riskier tokens. Cardano’s privacy token NIGHT remained heavily negative at -0.1987%, indicating a strong preference for short positions.
Altcoin performance
Altcoins broadly lagged, with CoinMarketCap’s “altcoin season” index falling to a fresh cycle low of 14 out of 100. Ether was an exception, gaining 1.5% against bitcoin between 2:50 a.m. and 10:30 a.m. UTC, though the ETH/BTC pair had been in a downtrend earlier in the week.
Bitcoin’s choppy trading has weighed on other altcoins as well, with RNDR, IMX, WLFI, and ATOM all declining in recent hours. Analysts say altcoins may regain momentum only if bitcoin breaks key resistance levels and consolidates, allowing capital to flow from BTC gains into higher-risk assets.
Muted speculative activity is reflected in CoinDesk’s memecoin index, which rose 2.42% since midnight UTC, compared with a 3.68% gain in the broader CoinDesk 20 index over the same period.
