BTC rises 0.6% in 15 minutes: $9.3 billion options expiration triggers Delta hedge buying, combined with technical oversold rebound.

June 26, 2026 19:00-19:15 UTC, BTC briefly surged 0.60%, with price rebounding to the 59615.5-60090.0 USDT range, amplitude 0.80%. This period fell within a critical window after the massive Deribit options expiration. Following two consecutive days of sharp declines, the market experienced a rebound from oversold conditions, with significantly amplified volatility.

The main driver of this anomaly was the Delta hedge unwinding effect after Deribit options expiration. Data shows that on June 26, a total of 157.8K BTC options expired, with a notional value of approximately $9.32 billion, accounting for 34.6% of total open interest in Deribit BTC options. Ahead of expiration, large put option hedging had exerted selling pressure in the spot market; once the expiration window began, market makers unwound their defensive Delta hedges, requiring them to buy back BTC in the spot market to cover short positions. The released buying demand directly pushed the price up by about 0.60% in a short time.

Second, technical oversold bounce constituted another core driver. BTC broke below the psychological $60,000 level on June 25, hitting a 21-month low of $58,115, triggering a $1.48 billion leverage flush. After the concentrated sell-off, the market entered a state of "selling pressure exhaustion," with momentum indicators such as RSI already in oversold territory. The key support zone of $58,000-$60,000 attracted bargain hunters. Meanwhile, although the PCE inflation data remained elevated, it met expectations, marginally easing market concerns about runaway inflation. U.S. Treasury yields edged lower, and risk appetite slightly improved.

Short-term volatility risks should be noted. The options expiration effect is a one-time driver, and its subsequent sustainability remains to be observed. Continuous net outflows from spot ETFs indicate that institutional sentiment remains cautious. BTC is still in a downtrend below moving averages across all timeframes, and the rebound may face technical resistance.
