London markets opened sharply lower on Thursday after the United States Bureau of Labor Statistics released its April preliminary payroll figures at 13:30 BST, showing the American economy added just 68,000 jobs last month — less than a third of the 220,000 consensus forecast. The figure, which analysts described as a "statistical outlier" until confirmed by revisions, sent shockwaves through global equity and currency markets within minutes of publication.

By midday, the FTSE 100 had fallen 142 points to 8,634, its worst single-session performance since October's inflation scare. Mining stocks bore the sharpest losses, with Glencore and Anglo American each shedding over four percent as commodity prices fell on reduced expectations for near-term US demand. Banking shares followed, with Barclays, HSBC and Lloyds down between two and three percent.

The Bank of England factor

The sell-off arrived on the same morning that the Bank of England's Monetary Policy Committee voted five to four to hold the base rate at 4.25%, producing the sharpest internal split since 2012. Governor Andrew Bailey, speaking after the decision, struck a notably cautious tone, saying the committee was "monitoring incoming data at an unusually high frequency" — language that traders interpreted as a signal that the next move could come at the June meeting rather than August as previously anticipated.

Sterling's sharp decline complicated that calculus. A weaker pound raises import costs and contributes to domestic inflation, potentially keeping the Bank's hand forced even if growth data deteriorates. The pound has now given up all the gains it made against the dollar since January.

Sectors and movers

Not all corners of the London market suffered equally. Defensive stocks — utilities, healthcare, and consumer staples — held their ground or rose modestly as investors rotated toward safety. National Grid gained 0.9%, AstraZeneca added 0.6%, and Unilever edged up 0.3%.

Oil majors BP and Shell fell over two percent as Brent crude dropped below $74 a barrel for the first time since February, reflecting the same pessimism about US economic activity that dragged equity markets lower.

Analysts cautioned against reading too much into a single data print. "One month's payroll number with this much deviation from consensus almost always gets revised up in the following month," said Laura Finch, senior economist at Schroders. "The bond market hasn't fully capitulated, which suggests there are still buyers who think this is noise."

European markets moved in tandem with London, with the Euro Stoxx 50 falling 1.4% and Germany's DAX down 1.6%. US futures pointed to a weaker open on Wall Street, though the magnitude of losses was expected to depend heavily on whether the Federal Reserve's preferred inflation measure — the PCE index — due for release at 15:30 BST, offered any offsetting comfort.
