Bitcoin advances as spot BTC ETFs record major quarterly inflows during Iran volatility

U.S. spot bitcoin ETFs saw $458 million in net inflows, indicating that institutional investors are stepping in to absorb the market shock that briefly pushed bitcoin down to $63,000 over the weekend.

Bitcoin was trading close to $68,000 on Tuesday as U.S.-listed spot ETFs recorded $458 million in fresh inflows, according to data compiled by SoSoValue. The figure represents one of the strongest inflow days of the quarter, even as geopolitical tensions related to the conflict with Iran continue to create volatility across global markets.

The steady demand suggests that institutional investors view the recent turbulence in bitcoin—sparked by war-related headlines—as a short-term disruption rather than a sign of broader systemic risk.

Singapore-based trading firm QCP Capital said in a recent market note that the approximately $300 million in long liquidations triggered by weekend developments were “notable but contained.” The firm added that overall market positioning had already been reduced significantly in the weeks leading up to the event.

Derivatives markets echoed this view, according to QCP. One-day implied volatility briefly jumped to 93% following the news before quickly easing back, signaling that traders were hedging near-term event risk rather than preparing for a prolonged escalation.

Meanwhile, U.S. spot bitcoin ETFs recorded roughly $1.1 billion in inflows across three straight trading sessions last week, based on SoSoValue data previously cited by CoinDesk. About half of those inflows were directed into BlackRock’s IBIT fund.
