In Europe, the main stock exchanges opened mixed today amid a fresh escalation of tensions in the Middle East, which sent Brent crude prices up almost 4% as traffic through the Strait of Hormuz was reduced to virtually zero.
The euro is weaker, down 0.05% against the dollar, and is trading at $1.1410 on the Frankfurt foreign exchange market.
In a week in which stock markets had been pointing towards optimistic gains as the US corporate earnings season got underway, these prospects were challenged by the situation in the Strait of Hormuz, which remains uncertain after US President Donald Trump and Iran issued contradictory statements regarding its opening to maritime traffic following Sunday’s new wave of reciprocal attacks.
Trump said on Sunday that the Strait of Hormuz remains open to commercial traffic despite Iran’s announcement that it had blocked it.
On Sunday afternoon, US forces launched a new offensive against Iran with the aim of “further diminishing” its ability to attack commercial vessels passing through the Strait of Hormuz, according to the US Central Command (Centcom).
Consequently, the fragility of the ceasefire between the United States and Iran has reignited awareness of the potential for further developments in the conflict and brought oil back to the forefront of the market, with the price of a barrel of Brent crude, the benchmark in Europe, soaring.
The price of Brent crude, the European benchmark, for September delivery rose by 3.80% to $78.90 (around €69.12).
Natural gas for August delivery on the Dutch TFF market, the European benchmark, rose by 4.15% to €50.66 per megawatt-hour (MWh).
Wall Street stock futures, following Friday’s positive close, are down 1.18% for the Nasdaq and 0.10% for the Dow Jones.
