Iran Uranium Stance Roils European Markets, Stoxx 600 Whipsaws

European stocks ended a volatile session marginally higher on Thursday, as fresh geopolitical tensions stemming from Iran's nuclear program rattled investor sentiment. The pan-European Stoxx 600 index oscillated between gains and losses throughout the day, ultimately closing in the green after a mid-afternoon recovery. The instability followed reports that Iran's Supreme Leader issued a directive to keep enriched uranium within the country, a move that threatens to derail ongoing peace talks with the United States.

Geopolitical Shockwaves

According to sources cited by Reuters, Iran's Supreme Leader ordered that near-weapons-grade uranium should not be shipped abroad, directly contradicting U.S. demands for disarmament as a precondition for easing sanctions. The development came as the U.S. withdrew the biggest oil drawdown on record from the Strategic Petroleum Reserve (SPR) last week, underscoring the strain on global energy supplies. Source

Oil prices initially spiked on the news, with West Texas Intermediate (WTI) crude rising before settling down 1.94% at $96.35 per barrel, while Brent crude fell 2.32% to $102.58 per barrel. The reversal came as traders digested the potential for prolonged negotiations and the impact of a U.S. recession on demand. Europe's economy remains particularly vulnerable, with the energy price shock stifling demand and weighing on industrial output.

Bond Markets React

The uncertainty also spilled into bond markets. The U.S. 10-year Treasury yield edged lower by less than 1 basis point to 4.564%, while the 30-year yield dropped more than 2 basis points to 5.09%, reflecting heightened sensitivity to political risks. The 2-year yield, more attuned to Federal Reserve rate expectations, rose over 3 basis points to 4.072%. The moves came after a sharp pull-back in the previous session, when global bond yields retreated from multi-decade highs amid renewed inflation fears. Source

The Fed's April 27-28 meeting minutes revealed that a majority of officials anticipate raising interest rates if the Iran conflict drives inflation higher, adding another layer of uncertainty for equity markets.

Corporate Movers

On the corporate front, satellite operator Eutelsat surged 22% on Thursday, ahead of SpaceX's landmark initial public offering (IPO). Often described as the European challenger to Elon Musk's rocket-maker, Eutelsat's rally highlights the market's excitement around the space sector. However, the valuation gap is stark: SpaceX could be valued at a record-breaking $1.75 trillion at its IPO early next month, while Eutelsat's market capitalization stands at just €4.05 billion ($4.7 billion). German satellite maker OHB also posted strong gains, and Luxembourg's SES closed up 8%. Source

Elsewhere, EasyJet shares rose 0.9% after the low-cost carrier reported a pre-tax loss of £552 million for the six months to March 31, up from £394 million a year ago. The airline cited the Middle East conflict for delayed bookings and heightened costs. Ubisoft, the maker of Assassin's Creed, recovered from heavy losses to close down 2% after revealing an operating loss of €1.3 billion for its 2026 financial year. BT Group shares fell 4.9% as the telecoms giant reported a 4% decline in adjusted revenue to £19.6 billion, driven by lower international revenue.

SpaceX IPO and Crypto Crosscurrents

Adding to the market's complexity, Binance launched a perpetual futures contract tied to SpaceX on May 21, allowing retail traders to speculate on the private company's valuation before its IPO. The product, listed under ticker SPCXUSDT, is part of Binance's Pre-IPO Perpetual Contracts category. SpaceX's S-1 filing revealed Q1 revenue of $4.69 billion and a net loss of $4.28 billion, alongside a holding of 18,712 Bitcoin at a cost basis of roughly $35,000 per coin. The filing also suggested a possible Nasdaq debut as early as June. Source

Bitcoin's price, which had stalled near $80,000 about a week before the Binance launch, pulled back below $78,000 in the days that followed, reflecting the broader risk-off sentiment.

Outlook

The combination of geopolitical tensions, energy price volatility, and the upcoming SpaceX IPO is keeping European markets on edge. Investors will be closely watching the next round of U.S.-Iran talks and any further signals from the Fed on interest rate policy. For now, the Stoxx 600's marginal gain belies the underlying uncertainty that pervades the market.
