Switzerland stuns markets by giving up on currency peg

LONDON (AP) - Rarely has one statement prompted such a dramatic move in currency markets.

The Swiss franc achieved a turbo-charged lift Thursday after the Swiss National Bank, or SNB, ditched an increasingly expensive policy to limit the export-sapping rise of the currency. Within minutes of the early morning announcement, the currency spiked around a third against the euro and the dollar while Swiss shares tanked, prompting confusion and a fair degree of anger across trading room floors.

The decision by the SNB to call time on its efforts to prevent the euro from trading below 1.20 francs was a huge surprise and came amid mounting speculation that the European Central Bank will next week back a big stimulus program that will put more euros in circulation which would further dilute their value. That expectation has pushed the euro down to near-decade lows against the dollar.

As the outlook for the euro has darkened, the cost for the Swiss central bank of defending the peg by buying euros or selling francs has risen.

Though the timing of the Swiss decision proved a surprise, most foreign exchange experts thought the peg would have to be abandoned, just as previous such efforts had. In 1992, for example, the British pound suffered similarly dramatic losses as it crashed out of a fixed exchange-rate system that was then operating in Europe.

Like the Bank of England then, the Swiss central bank faced a tough task controlling its currency. That was evident in the franc's movements in the markets after it abandoned the peg. The euro plunged to a low around the 0.85 francs mark in the minutes after the decision, before recovering somewhat to trade 13 percent lower at 1.04 francs.

It wasn't just the euro that got caught up in the franc's frenzied moves. The dollar initially plunged by a similar amount, though it also recouped some of its kneejerk losses to trade 15 percent lower at 0.8884 francs.

"For years central banks have tried to avoid days like today by being transparent and making moves like this over time while drip feeding their intentions to the markets," said Craig Erlam, market analyst at Alpari. "The SNB have shown themselves to be amateurs today and there are many people that will suffer considerably as a result."
