Jitters about a global oil glut put the skids under London shares again on Wednesday.
The FTSE 100 Index slumped 158.95 points to 5717 as the price of a barrel of Brent crude fell 2.9% to US$27.9 and US light crude dropped 3.4% to US$28.6.
Analysts also said volatile Chinese markets overnight contributed to the downbeat sentiment. The Shanghai Composite closed about 1% adrift.
Michael Hewson at CMC Markets said: "Continued concerns of oversupply in the oil and gas market, set against a backdrop of slowing global growth, have seen stock markets across the globe slip back into bear market territory."
Meanwhile, figures from the UK's Office for National Statistics (ONS) showed a rise in Britons in work between September and November last year.
ONS statistician David Freeman said: “These results show the labour market continued to strengthen in the autumn. Real earnings continued to grow, albeit at a slower pace than in mid-2015."
Shares in JD Wetherspoon (LON:JDW) lost their fizz by 49.5p, or 7.3%, to 625p as the pub group revealed higher Christmas sales but said annual profits were likely to be towards the lower end of hopes.
Royal Dutch Shell (LON:RDSB) leaked 70p to 1299.5p on news that fourth-quarter profits may be 50% lower than last time, although it said it was confident about the planned merger with BG Group (LON:BG.) and was cutting 10,000 jobs this year. BG reversed 19.4p to 920.5p.
Victoria Oil & Gas (LON:VOG) shed a penny to 27.75p as the Cameroon-based gas supplier said seasonal influences on demand in the country, where the wet season boosts demand for hydroelectric power, meant production was lower than the previous quarter’s 8.2mln cf.
Genel Energy (LON:GNEL), the Middle Eastern-focused oil & gas company led by former BP boss Tony Hayward, backtracked 13.25p to 110.75p after it forecast its operations to break even on a cash basis at a Brent oil price of US$20 per barrel for 2016, although production rose.
MARKET PREVIEW
London’s blue-chip index is heading for a triple-digit loss at the open after heavy falls in Asia overnight.
Financial spread bet firms expects FTSE 100 to start the day 120 points below yesterday’s close of 5,877, mirroring heavy falls in Tokyo and Hong Kong.
The US was one of the few markets to avoid the carnage, with the Dow Jones Industrial Average managing to eke out a gain of 28 points to 16,016 after a rollercoaster day.
Oil caused many of the concerns again with a brief rally quickly snuffed out by after comments from the International Energy Agency that the world was drowning in glut of oversupply.
Brent crude fell back to just above US$28 a barrel with West Texas light oil priced even lower.
It may have given much to talk about at the World Economic Forum in Davos, but investors not at the junket have decided to vote with their feet.
Tokyo had fallen by almost 4% near the close of the trading day and the Nikkei is close to the official definition of a bear market with a near-20% decline from its recent high.
Hong Kong, meanwhile, is down to a three and a half year low and fell even more than Tokyo in percentage terms.
Companies releasing updates today probably wish they weren’t, but BHP Billiton, JD Wetherspoon and Genel Energy are all scheduled to report.
