The government and the Bank of England have both said that a Brexit would hurt the economy. Moody’s also warned that it could downgrade U.K.’s credit rating if the country leaves the union. By leaving the union, the UK would need to negotiate a new trade agreement with the EU that would preserve some of the trade benefits of EU membership.

“Looking at the Implied Volatility (IV) curve, we see that the IV30 is greater than the IV60, which is greater than the IV90. The implied volatility on the British Pound ETF is in steep backwardation. This means volatility is particularly expected in the near term.

Clearly, this news announcement is driving options pricing in the British Pound ETF and trading positioning in the GBPUSD,” according to See It Market.
