Crypto Markets Open June in the Red as Iran Tensions Drag

Bitcoin (BTC) fell at the start of June as U.S.-Iran military hostilities drove traders toward safer assets and spot Bitcoin ETFs logged their tenth consecutive day of net outflows, the longest losing streak on record. Ethereum (ETH) dropped alongside BTC, while Stellar (XLM) and Hyperliquid (HYPE) bucked the selloff and posted gains. The dual pressure of geopolitical risk and institutional product outflows marks a rough start to what traders had hoped would be a recovery month.

Bitcoin and Ether Lead a Soft Open

Bitcoin traded below $73,000 in Monday morning sessions, extending weakness from a difficult May.

Ether tracked lower in tandem, trading near $1,980. The broader cryptocurrency market shed ground across most large-cap tokens.

Futures markets, by contrast, showed a mild uptick in risk appetite, suggesting that at least some traders expect a short-term recovery. XLM added roughly 2% on the day, and HYPE climbed approximately 6%, pushing its market cap above $16 billion and into the top 10 by total cryptocurrency market cap.

ETF Outflow Streak Reaches Record Length

Spot Bitcoin ETF products recorded a tenth straight day of net outflows on May 30, the longest consecutive losing run since the funds launched in January 2024.

The streak follows a broader three-week withdrawal period for digital-asset investment products. CoinShares data cited by CoinDesk put last week’s net outflows from digital-asset investment products at $1.67 billion, stretching the losing run to three consecutive weeks.

The outflow trend suggests institutional allocators are reducing exposure as macro uncertainty deepens.

Background

Spot Bitcoin ETFs launched in the United States in January 2024 after years of regulatory resistance from the SEC. The funds gave institutional and retail investors regulated, exchange-listed access to Bitcoin price exposure without requiring direct custody of the asset.

May 2026 marked a sharp reversal from the inflow momentum that characterized much of early 2026. The month closed with $2.43 billion in total ETF outflows, the heaviest single-month withdrawal figure since launch.

The Iran conflict, which escalated through May after U.S. and Israeli strikes on Iranian military sites, has pushed oil prices higher and dented appetite for speculative assets including cryptocurrency.

What to Watch in June

Futures positioning shows traders have not fully abandoned the bullish thesis, but the gap between futures Optimism (OP) and spot selling represents a tension worth monitoring. Any ceasefire agreement or diplomatic breakthrough in the Iran conflict could remove the primary macro headwind weighing on risk assets.

On the ETF side, a single large inflow day could break the streak and shift narrative. Traders will also watch the U.S. jobs report due Friday, June 6, which could influence Federal Reserve rate expectations and Ripple (XRP) into cryptocurrency positioning.
