European equity markets closed broadly higher as investors positioned for two major macro events: the Federal Reserve's June rate decision and emerging details of a provisional US-Iran agreement. The Stoxx 600's 0.52% gain to 639.31 points reflected cautious optimism rather than aggressive risk-on positioning, as the market awaited confirmation of both events rather than pricing in certainty. The dual catalysts of potential Fed rate hold (reducing near-term monetary tightening risk) and Iran deal progress (reducing oil supply risk premium and geopolitical tail risk) created a constructive backdrop for European equities on the day.

The Fed rate hold and Iran deal progress carry different implications for European sector performance. A Fed hold stabilises EUR/USD by reducing the rate differential pressure that has weighed on the euro, benefiting European exporters through improved competitiveness. The Iran deal's oil price impact — driving crude toward three-month lows — is particularly beneficial for European industrials and consumer companies facing energy cost pressure. Energy sector stocks within the Stoxx 600, however, face the inverse dynamic: lower oil prices compress upstream revenue and sector earnings, creating a divergence within the index between oil-price beneficiaries and oil-price losers.

Watch the official Fed decision announcement and Iran deal implementation details for confirmation that both catalysts materialise as expected, as European markets had partly pre-priced these outcomes in Wednesday's session. The next European data releases — particularly eurozone CPI and PMI figures — will determine whether the ECB's own rate path remains on a cutting trajectory or faces recalibration. The macro variable is the EUR/USD exchange rate: a stronger euro from Fed hold and Iran-driven dollar softening would support European equity valuations for international investors but compress export-driven earnings growth for Stoxx 600 constituents.
