Elections and Political Risk: Trading Uncertainty Without Guessing Winners

Elections create uncertainty, and currencies dislike uncertainty. But predicting the effect is harder than it looks.

Markets price in expectations ahead of time. If polls show a clear favorite, the outcome may already be reflected in prices, and a win produces little movement. The surprise, when a result differs from polls, moves markets. The 2016 Brexit referendum showed this: the pound fell sharply overnight when the result defied expectations, hitting levels not seen in decades.

What matters is not who wins but what the policies imply: for trade, spending, taxes, and central bank independence. A pro-growth, market-friendly result may support a currency, while one raising fiscal or political concerns may weigh on it.

Volatility tends to build before major events as traders hedge, and implied volatility in options markets rises. After the result, there is often a sharp move followed by a gradual reassessment.

Practical caution: spreads widen and slippage rises on election nights, and results may take hours to emerge, creating erratic price action.

Many experienced traders reduce size or stay out around major political events. Their reason is that the outcome is unknowable, and trading it is closer to a bet than an analysis.

Practical step: mark major elections and referendums in the countries behind your pair, and decide in advance how you will handle open positions.

Personally I flatten before big results. The way I see it, there's no setup on a chart that tells you how millions of people will vote, and the spread on the night can be ugly.

If you do want exposure, the reassessment phase after the result is usually more tradeable. Once the initial spike is in and spreads normalize, the market starts pricing the actual policies, and that's slower and more readable.

For UK elections the key moment is easy to schedule: the broadcasters' exit poll at 22:00 on the night polls close. It has usually been close to the final result, and sterling reacts within seconds, at a time when liquidity is already thin after the New York close. The 2017 exit poll pointing to a hung parliament knocked cable down roughly two big figures almost immediately.

So for anyone holding GBP into an election, the risk isn't spread across the whole night. It's concentrated in that one minute, with the worst liquidity of the day, which makes the case for flattening beforehand even stronger.
