European shares edged down on Tuesday as investors entered a week heavy with central bank meetings and corporate earnings, while a diplomatic impasse in negotiations between the United States and Iran added to market caution.
U.S. officials signaled that President Donald Trump was unhappy with Iran's most recent proposal to resolve the two-month-long conflict. That proposal sought to delay discussion of Iran's nuclear programme until the war is over and until shipping disputes are settled, a stance that U.S. officials indicated was unsatisfactory.
The geopolitical disruption has unsettled global markets, pushing oil prices higher and renewing concerns about inflation and economic growth. Market participants noted that the strategically vital Strait of Hormuz remains closed, amplifying the supply worries that have contributed to recent price moves.
By 0704 GMT, the pan-European STOXX 600 index was down 0.3% at 606.94 points. Traders also observed that while Wall Street and other global markets had rallied back from a sharp selloff in March, energy-dependent European equities had not regained their pre-war levels.
Corporate results produced mixed reactions. Energy heavyweight BP saw its shares rise 2.3% after reporting first-quarter profit that exceeded expectations. By contrast, Swiss drugmaker Novartis experienced a 4.5% decline in its stock after disclosing quarterly core operating profit and sales that fell short of market estimates. Airline Norwegian Air Shuttle climbed roughly 4% following a quarter with an operating loss smaller than expected; the carrier cited support from a stronger Norwegian crown, jet fuel hedges and lower prices for EU Emissions Trading System allowances.
Separately, one market analytic service highlighted BP in the context of model-driven stock evaluations, noting that its system reviews thousands of companies across many financial metrics and has identified notable past winners. The service posed the hypothetical question of whether to invest $2,000 in BP and offered to compare BP with other opportunities in the sector.
Investors will be closely watching forthcoming central bank announcements and an ongoing flow of corporate earnings for cues on economic momentum and inflation, while developments in U.S.-Iran diplomacy continue to influence risk sentiment.
