Pound plunges, stock markets in turmoil on Brexit vote

Sterling hit a 31-year low, crashing 10 percent to $1.3229 at one point, and the euro also plummeted against the US currency, as the Brexit result caught markets by surprise.

European stock markets went into free fall at the opening, mirroring a rout in Asian markets, after markets had banked on Britons opting to remain in the EU based on polls and bookmakers predictions.

London's benchmark FTSE-100 index plummeted 7.5 percent after opening but recovered some of the losses as the news sank in and British Prime Minister David Cameron announced his resignation.

Around midday it was nearly five percent down but the losses represented less than all the gains it had notched up in the week running up the historic result.

UniCredit Research economist Daniel Vernazza said British voters had snubbed warnings by "the overwhelming majority of expert economic opinion".

"Not surprisingly, this morning the referendum result has sent shock waves through global financial markets," he said in a note to clients.

Bigger losses were seen on the eurozone's main markets, Frankfurt and Paris, which both fell more than 10 percent at one point, as financial stocks took the biggest hit.

Both had slightly pared back losses by midday.

- Markets wrong-footed -

But investors were still clearly wrong-footed by the vote outcome.

European stock markets and the pound had gained steadily in the run-up to the referendum.

"It's scary, and I've never seen anything like it," James Butterfill, head of research and investments at ETF Securities, said in London. "A lot of people were caught out, and many investors will lose a lot of money," he told Bloomberg News.

Highlighting the uncertainty, Jean-Michel Six, of SP Global Ratings, told AFP that the Brexit result "increases" the risk of Britain losing its top notch credit rating.

And US investment bank JPMorgan Chase warned that it could relocate UK jobs abroad.

Fears are also growing that other EU members will push for referendums, posing the biggest threat to the future of the grouping since its inception almost 60 years ago.

That worry pushed stock markets in the eurozone's weaker southern economies even lower than their core counterparts, with Milan and Madrid stocks falling more than 10 percent, and Athens plunging more than 13 percent.

"Leave's victory has delivered one of the biggest market shocks of all time," said Joe Rundle, head of trading at ETX Capital.

The dollar slumped briefly to 99.02 yen, the first time it has gone below 100 yen since November 2013, before edging back up above 102 yen. The Japanese unit is considered a safe bet in times of uncertainty and turmoil.

Central banks sought to reassure financial markets.

The European Central Bank said it was ready to provide additional liquidity for the markets if needed, while the Bank of Japan said it was ready to work with peers to do the same.

The Bank of England said it would pump more than 250 billion pounds ($370 billion, 326 billion euros) into the financial system if needed.

- Gimme shelter -

The Swiss central bank said it had intervened in the foreign exchanges to stem the rise of the Swiss franc, which surged on safe-haven buying.

Investors also sought the relative safety of government bonds. The price on the German benchmark 10-year sovereign bond rose sharply, pushing its yield into negative territory for only the second time in its history.

UK government bonds also rose, taking their 10-year yield to a historic low.

Gold, a traditional refuge asset, struck a two-year high.

But elsewhere, billions of dollars were wiped off investment portfolios.

India's rupee, the Canadian dollar and the Singapore dollar all suffered heavy losses, while the South African rand lost six percent on the day as emerging markets were hurt by sudden risk-aversion.

The prospect of a severe hit to the global economy also hammered oil prices.
