The Treasury has published a paper analysing the costs of Britain leaving the EU. Its central assumption is that the UK would negotiate a bilateral trade deal with the EU similar to that between Canada and the EU. Under this assumption the Treasury estimates that, by 2030, GDP would be 6.2% lower than if the UK had remained in the EU, meaning that the average household would be £4300 per year worse off than it would otherwise have been. The analysis also finds that there would be a total reduction in tax receipts of £36 billion per year – far greater than any savings from lower contributions to the EU budget.
Not surprisingly the ‘Vote Remain’ campaign for the UK to stay in the EU has welcomed the analysis, seeing it as strong evidence in support of their case. Also, not surprisingly, the Vote Leave campaign has questioned both the analysis and the assumptions on which it is based.
The Treasury analysis looks at three possible scenarios: (a) a Canada-style bilateral arrangement (the central estimate); (b) the UK becoming a member or the European Economic Area – the ‘Norwegian model’ (according to the Treasury, this would reduce GDP by 3.8%); (c) no specific deal with the EU, with the UK simply having the same access to the EU as any other country that is a mamber of the WTO (this would reduce GDP by 7.5%). Thus the Norwegian model would probably result in a smaller reduction in growth, but the UK would still continue to make contributions to the EU budget and have to allow free movement of labour. Only in option (c) would it have total control over migration. Each of the estimates has a margin of error, giving a range for the reduction in GDP across the three scenarios from 3.4% to 9.5%.
The Treasury used a three-stage process to arrive at its conclusions, as explained in the FT article below:
First, it uses gravity models to estimate the effect of different trade relationships on the quantity of trade and foreign direct investment. Gravity models take into account how close countries are to each other geographically, as well as their historical links, rather than assuming that trade flows to wherever the lowest tariffs are.
Second, it uses external academic results to estimate the consequences for productivity – the efficiency of the UK economy – from different levels of trade and foreign direct investment.
Third, it plugs the productivity numbers unto a global economic model run by the National Institute of Economic and Social Research to estimate the long-run differences in national income and prosperity.
Clearly there is large-scale uncertainty over any forecasts 14 years ahead, especially when the relationship with the EU and other countries post-EU exit can only be roughly estimated. The question is whether the assumptions are reasonable and whether there would be substantial costs from Brexit, but not necessarily of £4300 per household.
The following articles look at the analysis and its assumptions. Unlike many newspaper articles, which clearly have an agenda, these articles are relatively unbiased and try to assess the arguments. Of course, it would be difficult to be totally unbiased and it would be a good idea to try to spot any biases in each of the articles.

The latest Bank of England’s Money and Credit release shows net lending (lending net of repayments) by Monetary Financial Institutions (MFIs) to individuals in February was £4.9 billion. Although down on the £5.4 billion in January, it nonetheless means that over the last 12 months the flow of net lending amounted to £52.8 billion. This is the highest 12-month figure since October 2008.
The latest credit data raise concerns about levels of lending and their potential to again impact on the financial well-being of individuals, particularly in light of the falling proportion of income that households are saving. As we saw in UK growth fuelled by consumption as households again lose affection for their piggy banks the saving ratio fell to an historic low of 4.2 per cent for 2015.
An important factor affecting the financial well-being of individuals and households is the extent of their indebtedness. Flows of credit accumulate to become stocks of debt. Stocks of debt affect the extent to which household incomes becomes prey to debt servicing costs. Put simply, more and more income, all other things being equal, is needed for interest payments and capital repayments as debt stocks rise. Rising stocks of debt can also affect the ability of people to further fund borrowing, particularly if debt levels grow more quickly than asset values, such as the value of financial assets accumulated through saving. Consequently, the growth of debt can result in households incurring what is called balance sheet congestion with deteriorating financial well-being or increased financial stretch.
Chart 1 shows the stocks of debt acquired by individuals from MFIs, i.e. deposit-taking financial institutions. It shows both secured debt stocks (mortgage debt) and unsecured debt stocks (consumer credit). The scale of debt accumulation, particularly from the mid 1990s up to the financial crisis of the late 2000s is stark.
At the start of 1995 UK individuals had debts to MFIs of a little over £430 billion, the equivalent of roughly 55 per cent of annual GDP (Gross Domestic Product). By the autumn of 2008 this had hit £1.39 trillion, the equivalent of roughly 90 per cent of annual GDP. At both points around 85 per cent of the debt was secured debt, though around the start of the decade it had fallen back a little to around 80 per cent. (Click here to download a PowerPoint of Chart 1.)

The path of debt at the start of the 2010s is consistent with a story of consolidation. Both financially-distressed individuals and MFIs took steps to repair their balance sheets following the financial crisis. These steps, it is argued, are what resulted in a balance sheet recession. This saw the demand for and supply of additional credit wane. Consequently, as Chart 1 shows debt accumulation largely ceased.
More recently the indebtedness to MFIs of individuals has started to rise again. At the end of February 2014 the stock of debt was just shy of £1.4 trillion. By the end of February 2016 it had risen to £1.47 trillion (a little under 80 per cent of annual GDP). This is an increase of 4.7 per cent. Interestingly, the rise was largely driven by unsecured debt. It rose by 13.4 per cent from £159.4 billion to £180.7 billion. Despite the renewed buoyancy of the housing market, particularly in South East England, the stock of secured debt has risen by just 3.6 per cent from £1.24 trillion to £1.28 trillion.
Chart 2 shows the annual flow of lending extended to individuals, net of repayments. (Click here to download a PowerPoint of Chart 2.) The chart provides evidence of cycles both in secured lending and in consumer credit (unsecured lending).
The growth in net lending during the 2000s was stark as was the subsequent squeeze on lending that followed. During 2004, for example, annual net flows of lending from MFIs to individuals exceeded £130 billion, the equivalent of close on 10.5 per cent of annual GDP. Secured lending was buoyed by strong house price growth with UK house price inflation rising above 14 per cent. Nonetheless, consumer credit was very strong too equivalent to 1.8 per cent of GDP.
Net lending collapsed following the financial crisis. In the 12 months to March 2011 the flow of net lending amounted to just £3.56 billion, a mere 0.2 per cent of annual GDP. Furthermore, net consumer credit was now negative. In other words, repayments were exceeding new sums being extended by MFIs.
Clearly, as Chart 2 shows, we can see that net lending to individuals is again on the rise. As we noted earlier, part of this this reflects a rebound in parts of the UK housing market. It is perhaps worth noting that secured lending helps individuals to purchase housing and thereby acquire physical wealth. While secured lending can find its way to fuelling spending, for example, through the purchase of goods and services when people move into a new home, consumer credit more directly fuels spending and so aggregate demand. Furthermore, consumer credit is not matched on the balance sheets by an asset in the same way that secured credit is.
Chart 3 shows the annual growth rate of both forms of net lending by MFIs. In essence, this mirrors the growth rate in the stocks of debt though changes in the stocks of debt can also be affected by the writing off of debts. What the chart nicely shows is the strong rates of growth in net unsecured lending from MFIs. In fact, it is the strongest annual rate of growth since January 2006 (Click here to download a PowerPoint of the chart.)
The growth in consumer credit, the fall in the saving ratio and the growth in consumer spending point to a need for individuals to be mindful of their financial well-being. What is for sure, is that you can expect to see considerable comment in the months ahead about consumption, credit and income data. Fundamental to these discussions will be the sustainability of current lending patterns.

According to the law of comparative advantage, trade can benefit all countries if they export goods which they can produce at lower opportunity costs than their trading partners. Trade enables all countries to consume beyond their production possibility frontier. What is more, trade can increase competition, which encourages firms to be more efficient.
That trade is beneficial has been generally accepted by governments around the world since the Second World War, with the General Agreement on Tariffs and Trade (GATT) and then the World Trade Organization (WTO) advocating the dismantling of trade barriers. Countries have participated in a series of trade ’rounds’, such as the Uruguay Round (1986–94) and most recently the Doha Round (2001–15). But since the financial crisis of 2008, there has been waning enthusiasm for freer trade and growing calls to protect strategic and/or vulnerable industries. To some extent this mirrors the growth in protection after the Great Depression of the early 1930s as countries sought to boost their own industries.
After some progress in the Doha round talks in Nairobi in December 2015, the talks effectively marked the end of a fourteen-year road for the round (see also). There was a failure to agree on a number of items and chances of resurrecting the talks seem slim.
The classic response to calls for protection is that it can lead to a trade war, with a net loss in global output as less efficient domestic industries are shielded from competition from lower-cost imports. Consumers lose from no longer having access to cheaper imported goods. Trade wars, it is argued, are a negative sum game. Any gains to one country are more than offset by losses elsewhere. In fact, it is likely that all countries will lose.
One argument for protection recognises the efficiency gains from free trade, but argues that current trade is distorted. For example, countries may subsidise the export of products in which they have a comparative disadvantage and dump them on the rest of the world. The WTO recognises this as a legitimate argument for tariffs, if they are used to offset the effect of the subsidies and make import prices more reflective of the cost of production.
But increasingly arguments go beyond this. Industries that are regarded as strategic to a country’s future, such as the steel industry or agriculture, are seen as warranting protection. With protection, investment may flow to such industries, making them more efficient and even gaining a comparative advantage at some point in the future.
Then there is the question of income distribution. Trade with poor countries may help to close the gap somewhat between rich and poor countries. The reason is that poor countries, with an abundance of labour, are likely to have a comparative advantage in labour-intensive products. The demand for exports of such products will help to drive up wages in such countries. However, income distribution within the rich countries may become less equal. Cheap imports from developing countries may depress the wages of unskilled or low-skilled workers in the rich countries.
Another argument concerns the devastation caused to communities by the closure of plants which are major employers. Workers made redundant may find it hard to find alternative employment, especially if their skills are specific to the plant that has closed. At least in the short term, it is argued that such industries warrant protection to allow time for alternative employers to be attracted into the area.
Arguments such as these are being used today in many countries as they struggle with slowing growth in China, a glut of global resources and overcapacity in certain industries.
The steel industry is a case in point. The announcement by Tata Steel that it intends to close the Port Talbot steel works has been met with consternation and calls for protection against subsidised Chinese steel imports. The USA already imposes tariffs of 256% on corrosion-resistant Chinese steel. The EU has proposed raising tariffs on Chinese steel to the full amount of the subsidy, but the UK has blocked this, not wishing to trigger a trade war with China. In the meantime, China has announced the imposition of a tariff of 46% on a particular type of hi-tech steel imported from the EU.
On the other side of the Atlantic, there have been growing protectionist calls from presidential front runners. Donald Trump and Ted Cruz on the Republican side, and Bernie Sanders and now Hilary Clinton on the Democratic side, are opposed to the trade agreement that President Obama has been seeking with the EU – the Transatlantic Trade and Investment Partnership (TTIP). Donald Trump has proposed imposing tariffs of 45% on all Chinese imports.

The following articles look at the growing calls for protection, especially against China, and at the arguments about what should be done to protect the UK and EU steel industry.

The latest data in the Quarterly National Accounts show that UK households in 2015 spent £1.152 trillion, the equivalent of 62 per cent of the country’s Gross Domestic Product (GDP). In real terms, household spending rose by 2.8 per cent in 2015 in excess of the 2.3 per cent growth observed in GDP. In the final quarter of 2015 real household spending rose by 0.6 per – the same rate of growth as that recorded for the UK economy. This was the tenth consecutive quarter of positive consumption growth and the twelfth of economic growth.
It is the consistent growth seen over the recent past in real household spending that marks it out from the other components of aggregate demand. Consequently, household spending remains the bedrock of UK growth.
Chart 1 helps to evidence the close relationship between consumption and economic growth. It picks out nicely the stark turnaround both in economic growth and consumer spending following the financial crisis. Over the period from 2008 Q1 to 2011 Q2, real consumer spending typically fell by 0.4 per cent each quarter. This weakness in consumption was mirrored by economic growth. Real GDP contracted over this period by an average of 0.2 per cent each quarter. (Click here to download a PowerPoint of the chart.)
Since 2011 Q3 real consumption growth has averaged 0.6 per cent per quarter – the rate at which consumption grew in 2015 Q4 – while, real GDP growth has averaged 0.5 per cent per quarter. Over this same period the real disposable income (post-tax income) of the combined household and NPISH (non-profit institutions serving households), has typically grown by 0.4 per cent per quarter. (NPISHs are charities and voluntary organisations.)
The strength of consumption relative to income is evidenced by the decline in the saving ratio as can be observed in Chart 2. The ratio captures the percentage of disposable income that households (and NPISHs) choose to save. In 2010 Q3 the proportion of income saved hit 11.9 per cent having been as low as 4.5 per cent in 2008 Q1. By 2015 Q4 the saving ratio had fallen to 3.8 per cent, the lowest value since the series began in 1963 Q1. (Click here to download a PowerPoint.)
The historic low in the saving ratio in the final quarter of 2015 reflects the strength of consumption alongside a sharp fall in real disposable income of 0.6 per cent in the quarter. However, the bigger picture shows a marked downward trend in the saving ratio over the period from 2012.
When seen in a more historic context the latest numbers taken on even greater significance. Chart 3 shows the annual saving ratio since 1963. From it we can see that the 2015 value of 4.2 was the first year when the ratio fell below 5 per cent. With 2014 being the previous historic low, there must be some concern that UK consumption growth is not being underpinned by income growth. (Click here to download a PowerPoint.)
Of course, consumption theory places great emphasis on expected future income in determining current spending. To some extent it may be argued that households were liquidity-constrained following the financial crisis. They were unable to borrow to support spending and, as time moved on, to borrow against the expectation of stronger income growth in the future. This would have depressed consumption growth. But, there may also have been a self-imposed liquidity constraint as the financial crisis unfolded. Heightened uncertainty may have led households to be more prudent and divert resources to saving. Such precautionary saving would tend to boost the saving ratio and so may be a factor in the sharp rise we observed in the ratio.
The easing of credit constraints as we headed through the early 2010s allied with stronger economic growth may help to explain the strength of the recovery in consumption growth. However, it is the extent and, in particular, the duration of this strong consumption growth that is fuelling a debate over its sustainability. The current uncertainty around future income growth and the need for households to be mindful of the indebtedness built up prior to the financial crisis point to households needing to retain a degree of caution. Consequently, the debates around the financial well-being of households and the need to rebalance the UK economy away from consumer spending are likely to be further intensified by the latest consumption and saving data.

On 20 February, the UK Prime Minister, David Cameron, announced the date for the referendum on whether the UK should remain in or leave the EU. It will be on 23 June. The announcement followed a deal with EU leaders over terms of UK membership of the EU. He will argue strongly in favour of staying in the EU, supported by many in his cabinet – but not all.
Two days later, Boris Johnson, the Mayor of London, said that he would be campaigning for the UK to leave the EU.
In the meantime, Mr Johnson’s announcement, the stance of various politicians and predictions of the outcome of the referendum are having effects on markets.
One such effect is on the foreign exchange market. As the Telegraph article below states:
The pound suffered its biggest drop against the dollar in seven years after London Mayor Boris Johnson said he will campaign for Britain to leave the European Union [‘Brexit’].
Sterling fell by as much as 2.12pc to $1.4101 against the dollar on Monday afternoon, putting it on course for the biggest one day drop since February 2009. Experts said the influential Mayor’s decision made a British exit from the bloc more likely.

The pound also fell by as much as 1.2pc to €1.2786 against the euro and hit a two-year low against Japan’s yen.
This follows depreciation that has already taken place this year as predictions of possible Brexit have grown. The chart shows that from the start of the year to 23 February the sterling trade weighted index fell by 5.3% (click here for a PowerPoint).
But why has sterling depreciated so rapidly? How does this reflect people’s concerns about the effect of Brexit on the balance of payments and business more generally? Read the articles and try answering the questions below.
