UK Referendum: The Calm Before The Storm Or Another Y2K?

 | Jun 23, 2016 02:15AM ET

GBP/USD has stormed to the highest level of the year, taking the gains in the last five days close to 6% and has $1.5000 firmly in its sights. GBP/JPY has pushed up a lazy 900 pips in the same time, but yet if we look at GBP/USD risk reversals (these measure the skew of put optionality over calls) we can see they are still at record lows. GBP may have moved, but there is still plenty of juice in the tank as ‘Brexit’ hedges are still very much in the market.

With GBP/USD spot trading shy of $1.4800 we can buy a $1.4800 call and put (expiring this Friday) for a cost of 748 points. To breakeven on ‘buying volatility’ (using a ‘strangle’ strategy) we need GBP/USD to close above $1.5548 or below $1.4052. Of course GBP/USD implied volatility being near all-time highs is a key input in options pricing, but the mentioned range is a huge consideration and gives an idea on the potential moves by the end of the week. Clearly if you are of the view that the UK referendum is the next Y2K then selling volatility is probably a compelling trade. With unlimited risk in selling volatility this is a strategy I will not go near!

The divergence between the bookies and polls is something that many focus on. Taking into consideration what we have seen with the overnight night’s polls we are staring at something very close indeed. The poll of polls, which accounts for the average of the last six polls is literally 50:50. Britain Elects (follow them on Twitter) has the ‘remain’ vote just ahead at 50.8% to 49.2%, if one is to exclude the ‘don’t know’ vote. The polls are tight.
