From landslide to upset defeat — scenarios for British election

British Prime Minister Theresa May’s narrowing lead in opinion polls ahead of the June 8 election has weakened sterling and raised questions over whether she will win the landslide predicted just a month ago.
The vote will decide whether May or her Labour Party rival Jeremy Corbyn takes control of Britain’s exit from the European Union — a two-year negotiation which will plot a new course for the $2.6 trillion economy.
The prime minister called the snap election in a bid to strengthen her hand in Brexit negotiations, to win more time to deal with the impact of the divorce and to strengthen her grip on the Conservative Party.
While she is still expected to win, with a lead of between five percentage points and 14 points in six polls released over recent days, financial markets are now digesting a bigger range of outcomes than they previously had considered.

Sterling rallied in April when May called the vote as investors bet her then large poll lead would translate into a big majority, reducing uncertainty over whether she would have the mandate required to negotiate on Britain’s behalf and then drive the deal through parliament.
The snap election pushes back the date of the next planned national election from 2020 — just after Britain is due to have quit the EU — to 2022, giving May more time to put the exit deal in place and potentially reducing political risk over how the deal is implemented.
Some also take the view that a big majority would allow her to make compromises with Brussels, in contrast to a hardline approach to date that has prioritised issues like immigration and trade over access to Europe’s lucrative single market.
That all helped push sterling to an eight-month high of $1.3048 last week.US bank Citi said a majority of more than 100 seats would lower the risk of a chaotic EU exit, but also reduce the chance that Britain could remain a member of the EU single market.
“Ultimately, with a big majority for the Conservatives confirming a ‘hard-but-smooth’ Brexit base case, we think that abating uncertainty risks could see GBP/USD head towards 1.34 in the near term,” Citi strategists said in a May 19 note.
The Conservatives’ lead fell sharply after May announced plans to make elderly voters pay more towards their old age care, while Corbyn has gained ground thanks to popular policies such as renationalisation and higher taxes for the rich.
Whilst still broadly predicting May will improve on the 12-seat victory her predecessor David Cameron won in 2015, the narrowing polls suggest a majority that might fall well-short of a 100-seat or more landslide.
Bank analysts said that would not undermine the central scenarios which have helped the pound in the past month but might still see it weaken from current levels.
“The correlation has been very clear in the past month: the bigger the (expected) majority, the firmer sterling has been,” said Adam Cole, head of G10 currency strategy at RBC Capital Markets in London.
“The current pricing is for a majority of more than 100, so I think the knee-jerk reaction to one of 50-100 (seats) would be lower.”
If May does not handsomely beat the 12-seat majority Cameron won in 2015, her electoral gamble will have failed, her ability to drive Brexit reform through parliament will be diminished and she will go into talks later this month looking weaker.
The converse view is that with less room for manoeuvre domestically, she will be able to reject compromises proposed by Brussels and drive a harder bargain, knowing that EU negotiators will not want May to execute her threat of leaving without a deal.
For investors the over-riding factor is likely to be greater uncertainty about whether there will be a deal on Brexit and what it will look like.
“May’s potential dependence on minorities such as hard Brexiteers or hard Remainers would raise the risk of ‘chaotic Brexit’, but also the chance of a much softer Brexit than she currently aims for,” Citi said.
If neither main party wins a clear majority, markets will have to deal with considerable uncertainty over who will form the next government and what compromises the eventual prime minister will have to make to get the support of other parties.
A clear win for Corbyn, whose less than two-year leadership has been marked by poor ratings, divisions among his party and a failed coup attempt, would force many investors to redraw their assumptions on both Brexit and the fiscal outlook.
History shows that sterling tends to weaken on big moves towards Labour in the polls. “In the event of such a ‘political earthquake’, the knee-jerk reaction would be a sharp move lower in sterling.
Under this scenario, we’d suggest the risks are to GBP/USD possibly touching $1.10,” Citi said earlier this month.
Longer term, analysts from a number of banks highlight the potential for both more borrowing to fund economic stimulus and the increased likelihood that Corbyn will negotiate a closer trading relationship with the EU than May would have done. — Reuters
