Why the hung parliament spells economic turbulence for Britain

Theresa May’s snap election wager has backfired. The supposed “Brexit election” was intended to signal the public’s support for the prime minister’s approach to the UK’s departure from the European Union

Instead, it has left her incredibly weak, without even a majority in government and her future as leader is uncertain. And the economic data reflects this.

Markets hate uncertainty. One measure that tracks this is the UK’s index of Economic Policy Uncertainty, which shows diminishing confidence around the country’s economic resilience. It is calculated by tracking daily articles relating to economic and political unrest in more than 650 newspapers in the UK. The higher the number, the more turbulent the economic outlook. The index surged from 286 on 18 May, 2017 to a staggering peak of 521 on 8 June, the day of the general election.

This is significant because higher levels of uncertainty are associated with greater stock price volatility and reduced investment and employment in key areas of the economy like healthcare and infrastructure.

The UK’s rising uncertainty levels stretch back to its EU referendum on 23 June, 2016. Since then, GDP growth increased by only 0.84% while inflation rose by 1.09%. Uncertainty around the UK’s future relationship with the EU and the Brexit negotiations has caused sharp movements in currency markets as a result of investors hedging their bets and speculating on trades. The day after the referendum, the euro to sterling exchange rate fell by a massive 6.2% overnight, while economic policy uncertainty hit a record value of 2,661. It fell a further 5.1% from June 2016 to May 2017 and 3.42% during the month of May 2017, alone.

It is clear that the negative relationship between policy uncertainty and the euro to sterling exchange rate is intensifying. This implies that increases in economic policy uncertainty are met with depreciations in the sterling to euro exchange rate running up to 9 June, 2017.

Downward direction

Amid the result of a hung parliament, the euro to sterling exchange rate changed from €1.154/£1 on 8 June (the day of the election) to €1.139/£1 on 9 June, 2017 (when the result became clear); an overnight plummet of over 1.25%. When comparing this change with 24 June, 2016, the fall does not seem too severe, but the key issue is whether sterling will continue to depreciate against the euro.

Although forecasts suggest the possibility that sterling could bounce back, there is also the risk that by 14 June, sterling could be as much as 2.3% lower – relative to the euro – than the day before. The fact that sterling has been falling – reaching a low of €1.131/£1 just before midday – since markets opened on 12 June, suggests that it is going in one direction. Down.

Brexiteers argue that export-led businesses in the UK will benefit from a favourable exchange rate. Indeed, the UK exports 44% of its goods and services to the euro area and with persistent depreciations in sterling relative to the euro, this makes UK exports more competitive.

This is all well and good while the UK is still a member of the single market. In the longer-term, the absence of free trade, coupled with the possibility of a sour deal, points toward the imposition of tariffs on UK exports. In turn, euro area nations may be encouraged to (freely) trade with remaining EU member states for comparable goods and services; a threat that businesses regard a risk at a three year horizon.

A lack of credibility

So the markets are clearly unconvinced of the prime minister’s message of strength and stability. The daily volatility of exchange rate changes on 9 June, the day after the election, was 0.35%, a staggering 0.2 percentage points higher than a month earlier. The markets are worried.

This rising exchange rate volatility also hurts export-led firms. It results in them acting cautiously, as their future earnings and investments remain exposed to the risk of exchange rate fluctuations.

The ConversationThe implication here is that currency markets do not feel the government’s current position for Brexit negotiations is strong. This, coupled with May’s lack of support in the general election, should put her leadership into question, particularly when it comes to entering divorce talks with the EU. The very fact that the domestic political landscape of the UK is shrouded by yet another layer of uncertainty suggests that economic policy, the exchange rate, and indeed the wider economy, is in for a rough ride.
