BTC 15-minute short-term rebound 0.48%: FOMC meeting plus easing tensions between the US and Iran drive a cooling of risk-off sentiment

From 11:15 to 11:30 (UTC) on June 15, 2026, BTC delivered a +0.48% return within 15 minutes. The trading price range was 65,929.8 - 66,382.8 USDT, with a swing of 0.69%. At that time, the Asian and European trading sessions were transitioning, and market volatility noticeably intensified. Bitcoin shifted from the relatively quiet trend in the early Asian session to a rapid rally.

The main driver behind this abnormal move was a revision of policy expectations prompted by the upcoming FOMC meeting. June 15 was the formal meeting date, and market focus shifted from the prior question of “whether there would be rate hikes” to “whether the policy stance would ease at the margin.” Because Bitcoin is highly sensitive to interest-rate expectations, it bounced first as policy expectations improved.

In addition, a simultaneous easing of geo-political tensions between the US and Iran and a sharp plunge in crude oil created a clear resonance effect. By the European session on June 15, US-Iran negotiations were nearing the signing of the talks agreement. WTI crude oil briefly broke below $80, with an intraday drop exceeding 5%. As risk-aversion sentiment cooled, capital flowed back into risk assets. Bitcoin, as an asset positively correlated with traditional risk assets, benefited significantly. Bitcoin also successfully broke through the $65,000 level that day.

On the technical side, $60,000 acted as the largest bearish support wall on the full options book for the entire period (about 19,000 contracts). After losing $60,000 at the beginning of June, it received institutional buy-side follow-through. Data showed that near the $60,000 mark, the share of institutions selling put options surged to 42.0%, while buying call options rose to 33.0%. Institutions shifted from defensive hedging to bargain-hunting on dips. On-chain trading activity stayed high: exchange reserves continued to decline, tightening the floating supply available for selling—together forming structural buy-side support.

Key points to watch include policy uncertainty after the FOMC dot plot is released. If hawkish signals are delivered, Bitcoin could face renewed pressure. ETF fund flows remain a crucial indicator: although the early-June outflow trend has paused, the net flow position for the year to date has already turned into net outflows. Short-term volatility risk still exists. It is recommended to monitor the effectiveness of the $60,000 support and how subsequent macro events play out.
