LONDON (Reuters) - A surprisingly close U.S. election contest caused the dollar to swing around in cash markets on Wednesday but derivatives market "fear" gauges showed implied currency volatility declining from multi-year highs as big bets on a weaker dollar were unwound.
Unlike in March, when the coronavirus crisis unleashed mayhem in markets, reactions were relatively contained with a 1% jerk higher in the dollar abating as vote counting progressed and diluted President Donald Trump's early lead.
Overnight gauges of euro-dollar implied volatility had surged on Tuesday
Currency market players said expectations of a Democrat clean sweep had led many traders to place bets on the dollar falling, but the close race had fuelled a rally instead, washing out some of those trades.

"I think people definitely want to keep their powder dry for when they see a more conclusive result," said Stuart Oakley, London-based global head of cash currency trading at Nomura.
Trump's wins in the battleground states of Florida, Ohio and Texas confounded investors' hopes for a clear result and the wait is on to see if he retains the so-called Rust Belt states -- Michigan, Wisconsin and Pennsylvania -- that sent him to the White House in 2016.
Marvin Barth, head of FX and EM macro strategy at Barclays (LON:BARC) recommended buying shorter-dated volatility gauges until a clear result emerged.
Even more broadly, a Deutsche Bank (DE:DBKGn) index which measures volatility in several currencies <.DBCVIX> slipped to a two-week low of 7.6%.
Currency funding markets meanwhile showed no sign of any rush to secure U.S. dollar funding as was seen during March. Dollar borrowing costs on the euro-dollar three-month swap market
"There doesn't seem to be any kind of stresses in the market or big asset allocation flows," said Chris Iggo, chief investment officer of core investments at AXA Investment Managers.
"For the moment I think most investors are just waiting to see what happens."
