The UK's top share index is facing its worst day since the financial crisis after it fell 8% in early trade, wiping billions off the value of major firms. The drop follows global falls as a row between Russia and Saudi Arabia saw oil prices plunge by more than a fifth. Shares were already reeling from fears of the impact of the coronavirus as cases globally continue to rise. The day has already been dubbed "Black Monday" by analysts who described the market reaction as "utter carnage". The FTSE 100 index fell more than 8% in the first few minutes of trade, before recovering slightly to stand 6% lower.
Oil prices are down more than 20% with Brent crude trading at $35.98 a barrel.
"It shows a level of nervousness in the market which I haven't seen in a long time," said Justin Urquhart-Stewart, co-founder of Seven Investment Management.
Investors are selling stocks at such a rate because they cannot quantify what Saudi Arabia and Russia might do, he said. The hefty falls were also seen elsewhere in Europe, with stock markets in France and Germany opening 7% lower. Norway - a major oil exporter - saw its main stock exchange fall 12% in early trade. Earlier on Monday, Asian markets had fallen sharply, with Japan's Nikkei 225 index down 5% while Australia's ASX 200 slumped 7.3% - its biggest daily drop since 2008. In China, the benchmark Shanghai Composite fell 3%, while in Hong Kong, the Hang Seng index sank 4.2%. As well as the slump in the oil price, Asian investors also reacted to a steep fall in Chinese exports, and figures showing the Japanese economy shrinking at a faster pace than expected//BBCnews
