FX options flag uncertainty before US midterm election

New York

CURRENCY options investors are bracing for increased volatility and possible US dollar weakness going into the US midterm elections next month.

But in the bond market, investors don't see the midterm election as a major catalyst for moves in interest rates.

Hedging activity increased in October in the yen, Australian and New Zealand dollars versus the greenback for maturities as far out as one year, strategists said.

Control of the US Congress is at stake in the Nov 6 election. Polls suggest the most likely outcome will be Democrats winning control of the House of Representatives with Republicans retaining the Senate.

A divided Congress could mean government gridlock, and this prospect has spawned some complacency in the bond market. Investors believe this outcome would not change the underlying upward trajectory of US economic growth nor the pace of interest rate increases by the Federal Reserve, analysts said.

It's a different story, however, for the currency market where investors are pricing in election-related risks.

"There has been a rise in hedging activity across all tenors for dollar/yen in October from the previous month that may be related to the US midterm elections," said Alice Leng, quantitative strategist at Bank of America Merrill Lynch in New York. "The sharpest rise in volume is between six months to one-year. So the market right now is looking at longer-term risks," she added.

To be sure, there are other factors contributing to a rise in hedging such as the escalating trade conflict between the US and China. Investors use options to protect positions or simply bet on event risk within certain periods of time.

The implied volatility or "vol" used by banks to price one-month options on dollar/yen rose as high as 6.8 on Friday. The metric reached 7.57 the previous week after hitting a nine-month low in September. Implied volatility measures expectations of increased moves in a currency pair in either direction.

Implied vols on six month to one-year maturities on dollar/yen also showed a pick-up, data showed.

Aside from increased volatility, dollar/yen's one-month risk reversal, an option market signal used to measure sentiment on currencies, showed bearish bets.

One-month risk reversals on dollar/yen showed bets for a drop in the dollar against the yen, although bearish sentiment has eased a little bit.

Mark McCormick, head of North American FX strategy at TD Securities in Toronto, said there is a bit of "a skew to the downside in the dollar" ahead of the elections.

"A divided Congress could see the market start to question how much longer US assets can outperform the rest of the world," Mr McCormick said.

He cited the rising correlation between the strength in the dollar and the outperformance of US equities the last few months, which he said could be highly sensitive to the US midterms.

Hedging volume activity has also picked up in the longer-term options of the Australian and New Zealand dollars. Investors buy the Aussie and New Zealand dollar when they have a higher risk appetite, and they tend to sell them in times of market uncertainty. One-year Australian and New Zealand dollar implied vols have tracked an upward trend since early August. REUTERS
