The closure of Europe's busiest airport due to a fire at a nearby substation impacts airline stocks and the broader market.
The FTSE 100 experienced a decline on Friday, with airline stocks suffering significant losses in the aftermath of a fire that led to the closure of Heathrow Airport, the UK's largest airport.
The index fell by 55 points, concluding the day at 8,647, which represents a drop of 0.6%.
Heathrow Airport was closed for the majority of the day due to a blaze at a nearby electricity substation, which has affected approximately 200,000 passengers.
The airport has issued warnings of "significant disruption" in the coming days but expressed hope for a return to full operations by Saturday.
Shares in International Airlines Group, the parent company of British Airways, declined by 2.9%, while easyJet shares saw a decrease of 0.9%.
The situation has echoed past disruptions in the airline industry, particularly those experienced during the
COVID-19 pandemic, as noted by investment analysts.
Further afield, Wall Street mirrored this decline with the S&P 500 down by 0.2% and the Dow Jones Industrial Average falling by 0.1% shortly after the UK markets closed.
In Europe, Germany’s DAX index fell by 0.5% and France's CAC 40 dropped by 0.6%.
The British pound also softened, falling 0.4% against the US dollar, trading at 1.2918, while it remained relatively stable against the euro at approximately 1.1942.
In corporate developments, Tim Martin, founder and chairman of JD Wetherspoon, cautioned that the pub chain would face mounting pressures from escalating labor costs and tax disparities with its retail competitors in the upcoming year.
The company, which operates 796 pubs across the UK, reported a 5% increase in sales in recent weeks, suggesting a resilient performance ahead despite ongoing pressures on consumer budgets.
However, JD Wetherspoon reported lower profits for the preceding year and signaled expectations of additional cost challenges.
