Europe open: Shares fall as rising bond yields spook investors

In Britain, official flash data showed a surprise fall in inflation to 2.8% in April compared with forecasts of 3% although most analysts expect this to change later in the year when the energy shock caused by the war kicks in to prices.

Yields on US bonds continued to rise as US President Donald Trump's war of choice on Iran showed no signs of a resolution, even as he made his oft-repeated claim that the conflict would end "very quickly".

In Japan, the 10-year yield neared 2.80%, the highest level in nearly 30 years, triggering fears of repatriation as the government could borrow more money to mitigate the impact of higher energy prices.

Traders are worried that the inevitable inflationary impact from higher energy costs due to the conflict will see central banks globally raise the cost of borrowing.

"It's the same story, different day. Trump yesterday first called off an attack on Iran, then said he would resume strikes if they can't agree on a deal," said Swissquote analyst Ipek Ozkardeskaya.

"Alas, geopolitical uncertainties continue. Traffic through the Strait of Hormuz remains at a near standstill, world oil inventories continue tightening, and oil prices keep rising. The latter fuels global inflation expectations and pushes global yields higher on rising bets that central banks may have to fight price pressures despite the worsening economic outlook."
