秒杀 SNB destroys currency brokers
就算反应过来，也根本没有交易， 秒杀。
The $5.3-trillion per day world of forex trading was crippled Thursday by the Swiss National Bank’s shock abandonment of its ceiling for the Swiss franc versus the euro. The Wall Street Journal today carries a sad story of how the move left, not only retail customers devastated by the move, but also companies decimated by exposure to the magnitude of the movement in currency immediately following the move. The chart below considers mounting losses facing an investor short of just one Chicago-traded Swiss franc currency futures contract worth CHF 125,000. I assumed a short position was taken 15-minutes ahead of the SNB’s 4:30am ET decision at a price of 97.98. Upon the announcement the Swiss unit had strengthened to 100.88 creating a per contract loss of $3,625. By 4:31 the loss was extended to $4,525 as the Swiss improved to 101.6 against the dollar. By 4:33am the Swiss had extended to a high of 102.11 pushing losses above $5,000. The violent reaction in those two minutes pretty much wiped out any available liquidity in the futures market. Over 8,000 contracts trade during that two-minute time period according to exchange data. In the next 28-minutes volumes totaled just half that amount indicative of lack of vendors willing to post liquidity as they tried to find liquidity in related markets. The most liquid spot market also saw vendors briefly stop quoting during the scramble. Some 24-minutes after the announcement, the single short Swiss future position had racked-up losses of $29,050 or more than five-times the required margin needed to post the trade.
