There have been many analyses of the economic effects of Brexit, both before the referendum and at various times since, including analyses of the effects of the deal negotiated by Theresa May’s government and the EU. But with the prospect of a no-deal Brexit on 31 October under the new Boris Johnson government, attention has turned to the effects of leaving the EU without a deal.
There have been two major analyses recently of the likely effects of a no-deal Brexit – one by the International Monetary Fund (IMF) and one by the Office for Budget Responsibility (OBR).
The first was in April by the IMF as part of its 6-monthly World Economic Outlook. In Scenario Box 1.1. ‘A No-Deal Brexit’ on page 28 of Chapter 1, the IMF looked at two possible scenarios.
Scenario A assumes no border disruptions and a relatively small increase in UK sovereign and corporate spreads. Scenario B incorporates significant border disruptions that increase import costs for UK firms and households (and to a lesser extent for the European Union) and a more severe tightening in financial conditions.
Under both scenarios, UK exports to the EU and UK imports from the EU revert to WTO rules. As a result, tariffs are imposed by mid-2020 or earlier. Non-tariff barriers rise at first but are gradually reduced over time. Most free-trade arrangements between the EU and other countries are initially unavailable to the UK (see the blog EU strikes major trade deals) but both scenarios assume that ‘new trade agreements are secured after two years, and on terms similar to those currently in place.’
Both scenarios also assume a reduction in net immigration from the EU of 25 000 per year until 2030. Both assume a rise in corporate and government bond rates, reflecting greater uncertainty, with the effect being greater in Scenario B. Both assume a relaxing of monetary and fiscal policy in response to downward pressures on the economy.
The IMF analysis shows a negative impact on UK GDP, with the economy falling into recession in late 2019 and in 2020. This is the result of higher trade costs and reduced business investment caused by a poorer economic outlook and increased uncertainty. By 2021, even under Scenario A, GDP is approximately 3.5% lower than it would have been if the UK had left the EU with the negotiated deal. For the rest of the EU, GDP is around 0.5% lower, although the effect varies considerably from country to country.
The IMF analysis makes optimistic assumptions, such as the UK being able to negotiate new trade deals with non-EU countries to replace those lost by leaving. More pessimistic assumptions would lead to greater costs.
Building on the analysis of the IMF, the Office for Budget Responsibility considered the effect of a no-deal Brexit on the public finances in its biennial Fiscal risks report, published on 17 July 2019. This argues that, under the relatively benign Scenario A assumptions of the IMF, the lower GDP would result in annual public-sector net borrowing (PSNB) rising. By 2021/22, if the UK had left with the deal negotiated with the EU, PSNB would have been around £18bn. A no-deal Brexit would push this up to around £51bn.
According to the OBR, the contributors to this rise in public-sector net borrowing of around £33bn are:
- A fall in income tax and national insurance receipts of around £16.5bn per year because of lower incomes.
- A fall in corporation tax and expenditure taxes, such as VAT, excise duties and stamp duty of around £22.5bn per year because of lower expenditure.
- A fall in capital taxes, such as inheritance tax and capital gains tax of around £10bn per year because of a fall in asset prices.
- These are offset to a small degree by a rise in customs duties (around £10bn) because of the imposition of tariffs and by lower debt repayments (of around £6bn) because of the Bank of England having to reduce interest rates.
The rise in PSNB would constrain the government’s ability to use fiscal policy to boost the economy and to engage in the large-scale capital projects advocated by Boris Johnson while making the substantial tax cuts he is proposing. A less optimistic set of assumptions would, of course, lead to a bigger rise in PSNB, which would further constrain fiscal policy.
- What are the assumptions of the IMF World Economic Outlook forecasts for the effects of a no-deal Brexit? Do you agree with these assumptions? Explain.
- What are the assumptions of the analysis of a no-deal Brexit on the public finances in the OBR’s Fiscal risks report? Do you agree with these assumptions? Explain.
- What is the difference between forecasts and analyses of outcomes?
- For what reasons might growth over the next few years be higher than in the IMF forecasts under either scenario?
- For what reasons might growth over the next few years be lower than in the IMF forecasts under either scenario?
- For what reasons might public-sector net borrowing (PSNB) over the next few years be lower than in the OBR forecast?
- For what reasons might PSNB over the next few years be higher than in the OBR forecast?
One of the key questions about Brexit is its effect on UK trade and cross-border investment. Once outside the customs union, will the freedom to negotiate trade deals lead to an increase in UK exports and GDP, as many who support Brexit claim; or will the increased frictions in trade with the EU, and the need to negotiate new trade deals with those non-EU countries which already have trade deals with the EU, lead to a fall in exports and in GDP?
Also, how will trade restrictions or new trade deals affect capital flows? Will there be an increase in inward investment or a flight of investment to the EU or elsewhere? Will many companies relocate away from the UK – or to it?
Although there has been a cost up to now from the Brexit vote, in terms of a depreciation in sterling and a fall in inward investment (see the first article below), the future effects have been hard to predict as the terms on which the UK will leave the EU have been unclear. However, with a draft withdrawal agreement between the EU and the UK government having been reached, the costs and benefits are becoming clearer. But there is still uncertainty about just what the effects on trade and investment will be.
- First, the 585-page draft withdrawal agreement is not a trade deal. It contains details of UK payments to the EU, commitments on the rights of EU and UK citizens and confirmation of the transition period – initially until 31 December 2020, but possibly extended with mutual agreement. During the transition agreement, the UK would remain a member of the customs union and single market and remain subject to rulings of the European Court of Justice. The withdrawal agreement also provides for a continuation of the customs union beyond the transition period, if no long-term trade agreement is in place. This is to prevent he need for a hard border between Ireland and Northern Ireland.
- Second, there is merely a 26-page ‘political declaration‘ about future trade relations. Negotiations on the details of these can only begin once the UK has left the EU, scheduled for 29 March 2019. So it’s still unclear about just how free trade in both goods and services will be between the UK and the EU and how freely capital and labour will move between them. But with the UK outside the single market, there will be some limitations on trade and factor movements – some frictions.
- Third, it is not clear whether the UK Parliament will agree to the withdrawal agreement. Currently, it seems as if a majority of MPs is in favour of rejecting it. If this happens, will the UK leave without an agreement, with trade based on WTO terms? Or will the EU be prepared to renegotiate it – something it currently says it will not do? Or will the issue be put back to the electorate in the form of a People’s vote (see also), which might contain the option of seeking to remain in the EU?
So, without knowing just what the UK’s future trade relations will be with (a) the EU, (b) non-EU countries which have negotiated trade deals with the EU, (c) other countries without trade deals with the EU, it is impossible to quantify the costs and benefits from the effects on trade and investment. However, the consensus among economists is still that there will be a net cost in terms of lost trade and inward investment.
Such as view is backed by a government analysis of various Brexit scenarios, released in time for the House of Commons vote on 11 December. This concludes that the UK will be worse off under all Brexit alternatives compared with staying in the EU. The main brake on growth will be frictions in trade from tariff and non-tariff barriers.
This analysis was supported by a Bank of England paper which modelled various scenarios based on assumptions about different types of Brexit deal. While recognising the inherent uncertainty in some of the empirical relationships, it still concluded that Brexit would be likely to have a net negative effect. The size of this negative effect would depend on the closeness of the new relationship between the UK and EU, the degree of preparedness across firms and critical infrastructure, and how other policies respond.
- Identify the main economic advantages and disadvantages for the UK from leaving the EU?
- How does the law of comparative advantage relate to the question of the relative trade gains from leaving and remaining in the EU?
- What is the difference between the following models of relationship with the EU: the Switzerland model; the Norway model; the Turkey model; the Canada (plus or plus, plus) model; trading on WTO terms?
- Why is the consensus among economists that there will be a net economic cost from leaving the EU, no matter on what terms?
- Is the UK likely to achieve more favourable trade deals with non-EU countries as an independent country or as a member of the EU benefiting from EU-negotiated trade deals with such countries?
In the light of the Brexit vote and the government’s position that the UK will leave the single market and customs union, there has been much discussion of the need for the UK to achieve trade deals. Indeed, a UK-US trade deal was one of the key issues on Theresa May’s agenda when she met Donald Trump just a week after his inauguration.
But what forms can a trade deal take? What does achieving one entail? What are likely to be the various effects on different industries – who will be the winners and losers? And what role does comparative advantage play? The articles below examine these questions.
Given that up until Brexit, the UK already has free trade with the rest of the EU, there is a lot to lose if barriers are erected when the UK leaves. In the meantime, it is vital to start negotiating new trade deals, a process that can be extremely difficult and time-consuming.
A far as new trade arrangements with the EU are concerned, these cannot be agreed until after the UK leaves the EU, in approximately two years’ time, although the government is keen that preliminary discussions take place as soon as Article 50 is triggered, which the government plans to do by the end of March.

Theresa May has said that the UK will quit the EU single market and seek to negotiate new trade deals, both with the EU and with other countries. As she said, “What I am proposing cannot mean membership of the single market.” It would also mean leaving the customs union, which sets common external tariffs for goods imported into the EU.
The single market guarantees free movement of goods, services, labour and capital between EU members. There are no internal tariffs and common rules and regulations concerning products, production and trade. By leaving the single market, the UK will be able to restrict immigration from EU countries, as it is currently allowed to do from non-EU countries.
A customs union is a free trade area with common external tariffs and uniform methods of handling imports. There are also no, or only minimal, checks and other bureaucracies at borders between members. The EU customs union means that individual EU countries are not permitted to do separate trade deals with non-EU countries.
Once the UK has left the EU, probably in around two years’ time, it will then be able to have different trade arrangements from the EU with countries outside the EU. Leaving the customs union would mean that the UK would face the EU’s common external tariff or around 5% on most goods, and 10% on cars.
Leaving the EU single market and customs union has been dubbed ‘hard Brexit’. Most businesses and many politicians had hoped that elements of the single market could be retained, such as tariff-free trade between the UK and the EU and free movement of capital. However, by leaving the single market, access to it will depend on the outcome of negotiations.
Negotiations will take place once Article 50 – the formal notice of leaving – has been invoked. The government has said that it will do this by the end of March this year. Then, under EU legislation, there will be up to two years of negotiations, at which point the UK will leave the EU.
The articles look at the nature of the EU single market and customs union and at the implications for the UK of leaving them.

The 159 member countries of the World Trade Organisation have reached an agreement on liberalising trade. The deal, which was reached on 6 December 2013 at a meeting in Bali, is the first substantial agreement since the WTO was formed in 1995 (see Timeline: World Trade Organization for other agreements).
It involves simplifying customs procedures and making them more transparent, limited reductions in tariffs and quotas and allowing greater access to WTO members’ markets for exporters. It also permits developing countries to continue subsidising their agriculture in order to promote food security, provided the practice does not distort international trade. According to the WTO:
The trade facilitation decision is a multilateral deal to simplify customs procedures by reducing costs and improving their speed and efficiency. It will be a legally binding agreement and is one of the biggest reforms of the WTO since its establishment in 1995. …The objectives are: to speed up customs procedures; make trade easier, faster and cheaper; provide clarity, efficiency and transparency; reduce bureaucracy and corruption, and use technological advances. It also has provisions on goods in transit, an issue particularly of interest to landlocked countries seeking to trade through ports in neighbouring countries.
In a report published by the Peterson Institute in Washington, it is estimated that the extra trade will add some $960bn to world GDP and create some 20.6m extra jobs. But how fully does it meet the objectives of the Doha Development Agenda, the yet-to-be-concluded trade round started in Qatar in November 2001?
According to the EU’s trade commissioner Karel De Gucht, about one quarter of the goals set for the Doha Round have been achieved in this agreement. This, of course, still leaves a long way to go if all the Doha objectives are to be met. World trade, although now likely to be somewhat freer, is still not free; developing countries will still find restricted access for their agricultural products, and manufactures too, to many markets in the rich world; rich countries will still find restricted access for their manufactured products and services to many markets in the developing world.
