In recent years there has been a lot of talk about how badly wrong pollsters can get it. Nobody thought Trump would win, nobody thought Leave would win the referendum, indeed even elections have been too close to call.\r\n\r\n\r\n\r\nThough it now feels like a different historical epoch to look back to 2010, then the pollsters were predicting a Conservative landslide that did not materialise \u2013 remember Clegg and Cameron having to do their Morecambe and Wise act in the rose garden?\r\n\r\nThis election, there are twin tenets of received wisdom. First is that the Tories are on for a comfortable win, second is that the election is volatile and we cannot be sure.\r\n\r\nNot very helpful, is it? So where to look for something more concrete, a better bellwether on which to make your decision down at the bookies? My recommendation would be the pound sterling.\r\n\r\nIt\u2019s important to remember that the City of London\u2019s financial services industry employs armies of \u2018analysts\u2019, whose job it is to read the runes all day and provide the trading floor with some mathematically sound, triangulated predictions and probabilities of what will happen next. That helps them make decisions about what stock and commodities to buy or offload.\r\n\r\nWhen it\u2019s not an election, this information can be anything from a major manufacturer going bust somewhere else in the world affecting the supply chain for a business they are invested in, or a Middle Eastern country descending into political turmoil affecting the oil price.\r\n\r\nI am no psephologist, so like most people I cannot completely get my head around how \u2018swing\u2019 works in elections, or how 42% of the national vote can deliver a thumping majority for one PM, but a hung parliament for another.\r\n\r\nAlso like most people, I do not have time to try to divine how a party is performing in all the marginal seats they need over the course of the election campaign, and as I\u2019ve said, polls are often wrong even when the race does not appear that close. This is where the pound sterling comes in handy.\r\n\r\nRight now, it\u2019s at a 31-month high against the euro, touching \u20ac1.19 for the first time since May 2017, just before the Tories lost their majority in Theresa May\u2019s snap election. This suggests unmistakably that the City is confident of a Boris Johnson victory.\r\n\r\nTo reiterate, it means traders both at home and internationally have been willing to buy British currency at higher prices than any other time in almost three years. Currency value is seen as the ultimate measure of investors\u2019 confidence in the future performance of a nation\u2019s economy. So if they\u2019re buying, and the price is climbing, it means they think the future is rosy. Or rosier than it was anyway.\r\n\r\nSo with that, I will throw my hat in the ring. My money\u2019s on a solid Boris Johnson majority on Thursday. Whatever your politics, the City thinks a Tory win will be good for business, and a win on Thursday may bode well for your bottom line in the coming five years.
