FTSE 100 Slides as Middle East War Fears Shake Markets and Oil Prices Surge

Market Reaction and Economic Impact

May 21 (Reuters) - UK's blue-chip shares fell on Thursday, pressured by downbeat data and worries that the Middle East conflict could remain deadlocked.

The blue-chip FTSE 100 index fell 0.43% as of 11:15 am GMT, while the midcap FTSE 250 was 0.18% higher.

Middle East Conflict and Oil Prices

• Iran's Supreme Leader has issued a directive that the country's near-weapons-grade uranium should not be sent abroad, Reuters reported, hardening Tehran's stance on one of the main U.S. demands ​at peace talks.

• The prolonged conflict has already pushed up oil prices and intensified concerns about inflation.

Economic Data and Business Sentiment

Business Activity and Inflation Concerns

• Separately, a survey on Thursday showed that British companies are suffering the most widespread drop in activity in over a year, due to the economic fallout from the war and political uncertainty at home.

• "These figures... lend some tentative support to other evidence that suggests the conditions for a long period of high inflation are not in place," said Paul Dales, chief UK economist at Capital Economics.

Recent Economic Indicators

Inflation and Unemployment

• Earlier this week, data showed that inflation in April was softer than expected, while the unemployment rate ticked up.

Factory Orders

• Meanwhile, factory orders in May contracted at the fastest rate since September 2020, according to the Confederation of British Industry.

Stock Market Movers

Biggest Laggards

• Shares of automotive marketplace Autotrader slipped 9.1% after the company reported slower sales, and were the biggest laggard on the FTSE 100.

Sector Performance

• Medical equipment and services shares fell 2.7%, dragged down by a 7.9% drop in medical equipment maker Convatec, which flagged margin pressure.
