Bitcoin fell 3.5% to $72,800 on May 28, hitting its lowest level in five weeks. The drop followed US military strikes on Iran near the Strait of Hormuz and massive outflows from institutional bitcoin funds. BlackRock’s iShares Bitcoin Trust shed $528 million in a single day, the second-largest outflow since launch. Geopolitical tension and profit-taking by large holders are driving the sell-off.
How Geopolitical Risk Triggered the Decline
US airstrikes on an Iranian military site near the Strait of Hormuz on May 28 reignited conflict that markets had begun to price out. Iran’s Revolutionary Guards responded with a retaliatory strike on a US airbase, escalating tensions significantly. This geopolitical uncertainty prompted investors to reduce risk exposure across crypto and other assets. Bitcoin, often seen as a hedge against instability, instead faced selling pressure as investors sought safer ground.
Institutional Investors Exit Bitcoin Holdings
All 11 US-listed spot bitcoin ETFs lost a combined $733.43 million on May 28. BlackRock’s IBIT shed $527.84 million, nearly matching its record outflow of $528.3 million from January 2026. Fidelity’s FBTC lost $60.30 million and Grayscale’s GBTC fell $104.76 million. Over two weeks, the complex has posted more than $2 billion in outflows. These redemptions forced issuers to sell underlying bitcoin, amplifying the price decline.
Technical Weakness and Meyka’s Assessment
Bitcoin’s technical indicators show oversold conditions. The Relative Strength Index (RSI) stands at 42.94, while the Commodity Channel Index (CCI) reads -112.56, signaling extreme oversold levels. Meyka rates BTCUSD a C+ with a HOLD suggestion. The 12-month price forecast stands at $97,867.61, suggesting limited upside from current levels if geopolitical tensions ease. Support levels remain critical: Bitcoin trades near the $72,000 mark with key buy zones identified at $60,000, $45,000, and $35,000.
What This Means for Investors
Bitcoin’s decline reflects both macro uncertainty and institutional profit-taking. The $733 million in single-day ETF outflows signals that large holders are reducing exposure rather than accumulating dips. Oil prices jumped over 3% on Iran tensions, raising inflation concerns and supporting higher interest rates, which typically pressure non-yielding assets like bitcoin. Investors should monitor ceasefire talks and the Strait of Hormuz situation closely, as further escalation could trigger additional selling.
Final Thoughts
Bitcoin fell to $72,800 on May 28 amid Iran tensions and $733 million in ETF outflows. Meyka rates the asset C+ with a $97,867.61 yearly target, suggesting limited recovery potential without a geopolitical resolution.
