March 19 (Reuters) - London's main indexes closed at

multi-month lows on Thursday after the Bank of England's

unanimous decision to leave rates unchanged, while the

intensifying Middle East conflict also suppressed risk appetite.

The blue-chip FTSE 100 finished at its lowest in

about two months, down 2.4%.

The mid-cap FTSE 250 was also down 2.4%, its lowest

level since November last year.

The BoE kept borrowing costs on hold as expected, warning of

inflation risks from the war in the Middle East. Some of the

policymakers also raised the prospect of raising rates.

"A low interest rate environment is beneficial for taxpayers

and businesses alike, but the risk of inflation is a more

important battle at this point," said Nick Saunders, CEO of

online investment platform Webull UK.

"The Bank cannot afford to fight a battle on two fronts."

CENTRAL BANKERS ARE CAUTIOUS

Traders are pricing in two 25-basis-point rate hikes by the

year-end.

Meanwhile, the European Central Bank kept its key interest rate

unchanged, also acting cautiously because of the war.

On Wednesday, the U.S. Federal Reserve held rates steady and

stuck to its projection for one cut in 2026.

In the UK market, the energy sector was the

only one to trade in a positive territory, rising 1.6% as oil

prices jumped after Iran attacked energy facilities across the

Middle East following Israel's strike on its South Pars gas

field, a major escalation in the war.

BP gained 4.9%. The oil giant agreed to sell its

Gelsenkirchen refinery to Klesch Group and raised its

cost-cutting target.

Earlier in the day, data showed that British wages rose at their

slowest pace since late 2020 in the three months to January,

according to official data that also suggested a weakening in

employment might have bottomed out before the start of the war

in the Middle East.

Of the 100 stocks on the FTSE 100, 97 finished in the red.

Metal miners and banks were down

7.8% and 4.3% respectively, making them the day's worst

performers.

HSBC ( HSBC ) dropped 3.1% after Bloomberg reported that the

bank is considering job cuts of up to 20,000 roles.
