STORY: French group Hermes led a slump in luxury shares on Wednesday.

It's after weak sales showed the war in Iran was weighing on demand in the Middle East and tourism in Europe.

It deals a fresh blow to hopes of a revival for the sector.

Shares in the Birkin bag maker sank as much as 14% in early trade.

The widespread impact of the conflict has been felt from Dubai mall sales to soaring energy prices hitting consumer confidence.

Shares in Gucci owner Kering fell more than 9% on Wednesday.

It followed Louis Vuitton owner LVMH which also said on Monday it had suffered a sharp slowdown in the Middle East.

Hermes carefully controls production and sales to maintain exclusivity.

It had been the most resilient luxury group in a years-long industry-wide slowdown.

But even it was not immune to the conflict's impact.

Its shares have dropped 24% far this year.

Luxury stocks have been increasingly volatile as hedge funds have ramped up bets in the sector.

Though only accounting for 4.4% of sales, the Middle East was the fastest-growing region for Hermes last year.

But first quarter sales in the region fell 6% in currency-adjusted terms to $188.59 million.

The strength of the euro has also become a major headache for luxury firms.

It took $342 million off Hermes' revenue in the quarter, leading to a 1% drop in reported sales.

The U.S. was a bright spot though, with currency-adjusted sales up 17.2%.
