Senior Bank of England officials appeared before the House of Commons’ Treasury Select Committee on 21 February to report on the state of the economy and the future path for inflation and interest rates. One topic considered was the role of depreciation.
The pound has depreciated since the referendum on EU membership in June 2016. The exchange rate index today is some 9% below that before the referendum and 15% below the peak a year before the referendum.
It had fallen as much as 14% by October 2016 below the level before the referendum and 20% below its peak, pushed down partly by the cut in Bank Rate from 0.5% to 0.25% following the referendum. In November 2017, the Bank’s Monetary Policy Committee raised Bank Rate back to 0.5%. Two or three more rises of 25 basis points are expected over the next couple of years. This has helped to strengthen sterling somewhat. (Click here for a PowerPoint of the chart below.)
But has the depreciation been advantageous or disadvantageous to the economy? Here the Governor (Mark Carney) and the Chief Economist (Andy Haldane) appeared to differ. Andy Haldane said:
A combination of the weaker pound and a stronger global economy has worked its magic. That has meant that net trade has been a significant contributor, and we expect those effects to continue over the next two or three years. … Depreciations work, and that’s how they work.
By contrast, Mark Carney said:
Depreciations don’t work. They have an economic effect, but they’re not a good economic strategy. They may be an outcome of various things … but it’s how you make yourself poorer.
Are these statements contradictory or are they simply emphasising different effects of depreciation?
Both Andy Haldane and Mark Carney would accept that a depreciation makes imports more expensive and thus reduces real incomes (at least in the short run). They would also accept that a depreciation makes exports priced in pounds cheaper in foreign currency terms and thus can boost the demand for exports.
There is disagreement over two things, however. The first is the effect on people’s real incomes in the long run. Will any fall in real incomes from higher-priced imports in the short run be offset in the long run by higher economic growth?
This relates to a second area of disagreement. This is whether a depreciation can act as a significant driver for exports over the longer term. The increased incentive on the demand side (from consumers abroad to buy UK exports) could be offset by a disincentive for exporters to become more efficient and/or to compete in terms of quality. In other words, although it can give exporters a price advantage, the crucial question is the extent to which they take advantage of this, or merely take higher profits.
The disagreements thus relate primarily to the incentive effects over the longer term.

One of President Trump’s main policy slogans has been ‘America first’. As Trump sees it, a manifestation of a country’s economic strength is its current account balance. He would love the USA to have a current account surplus. As it is, it has the largest current account deficit in the world (in absolute terms) of $481 billion in 2016 or 2.6% of GDP. This compares with the UK’s $115bn or 4.4% of GDP. Germany, by contrast, had a surplus in 2016 of $294bn or 8.5% of GDP.
However, he looks at other countries’ current account surpluses suspiciously – they may be a sign, he suspects, of ‘unfair play’. Germany’s surplus of over $50bn with the USA is particularly in his sights. Back in January, as President-elect, he threatened to put a 35% tariff on imports of German cars.
In practice, Germany is governed by eurozone rules, which prevent it from subsidising exports. And it does not have its own currency to manipulate. What is more, it is relatively open to imports from the USA. The EU imposes an average tariff of just 3% on US imports and importers also have to add VAT (19% in the case of Germany) to make them comparably priced with goods produced within the EU.
So why does Germany have such a large current account surplus? The article below explores the question and dismisses the claim that it’s the result of currency manipulation or discrimination against imports. The article states that the reason for the German surplus is that:
… it saves more than it invests. The correspondence of savings minus investment with exports minus imports is not an economic theory; it’s an accounting identity. Germans collectively spend less than they produce, and the difference necessarily shows up as net exports.
But why do the Germans save so much? The answer given is that, with an aging population, Germans are sensibly saving now to support themselves in old age. If Germany were to reduce its current account surplus, this would entail either the government reducing its budget surplus, or people reducing the amount they save, or some combination of the two. This is because a current account surplus, which consists of exports and other incomes from abroad (X) minus imports and any other income flowing abroad (M), must equal the surplus of saving (S) plus taxation (T) over investment (I) plus government expenditure (G). In terms of withdrawals and injections, given that:
I + G + X = S + T + M
then, rearranging the terms,
X – M = (S + T) – (I + G).
If German people are reluctant to reduce the amount they save, then an alternative is for the German government to reduce taxation or increase government expenditure. In the run-up to the forthcoming election on 24 September, Chancellor Merkel’s centre-right CDU party advocates cutting taxes, while the main opposition party, the SPD, advocates increasing government expenditure, especially on infrastructure. The article considers the arguments for these two approaches.

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 pound has fallen to its lowest rate against the euro since July 2013 and the lowest rate against the US dollar since 1985. Since August 2015, the pound has depreciated by 23.4% against the euro and 22.2% against the dollar. And since the referendum of 23 June, it has depreciated by 15.6% against the euro and 17.6% against the dollar.
On Sunday 2 October, at the start of the Conservative Party conference, the Prime Minister announced that Article 50, which triggers the Brexit process, would be invoked by the end of March 2017. Worries about what the terms of Brexit would look like put further pressure on the pound: the next day it fell by around 1% and the next day by a further 0.5%.
Then, on 6 October, it was reported that President Hollande was demanding tough Brexit negotiations and the pound dropped significantly further. By 7 October, it was trading at around €1.10 and $1.22. At airports, currency exchange agencies were offering less than €1 per £ (see picture).
With the government implying that Brexit might involve leaving the Single Market, the pound continued falling. On 12 October, the trade-weighted index reached its lowest level since the index was introduced in 1980: below its trough in the depth of the 2008 financial crisis and below the 1993 trough following Britain’s ejection from the European Exchange Rate Mechanism in September 1992.
So just why has the pound fallen so much, both before and after the Brexit vote? (Click here for a PowerPoint of the chart.) And what are the implications for the economy?
The articles explore the reasons for the depreciation. Central to these are the effects on the balance of payments from a possible decline in inward investment, lower interest rates leading to a net outflow of currency on the financial account, and stimulus measures, both fiscal and monetary, leading to higher imports.
Worries about the economy were occurring before the Brexit vote and this helped to push sterling down in late 2015 and early 2016, as you can see in the chart. This article from The Telegraph of 14 June 2016 explains why.
Despite the short-run effects on the UK economy of the Brexit vote not being as bad as some had predicted, worries remain about the longer-term effects. And these worries are compounded by uncertainty over the Brexit terms.
A lower sterling exchange rate reduces the foreign currency price of UK exports and increases the sterling price of imports. Depending on price elasticities of demand, this should improve the current account of the balance of payments.
These trade effects will help to boost the economy and go some way to countering the fall in investment as businesses, uncertain over the terms of Brexit, hold back on investment in the UK.

In a recent blog, Falling sterling – bad for some; good for others, we looked at the depreciation of sterling following the Brexit vote. We saw how it will have beneficial effects for some, such as exporters, and adverse effects for others, such as consumers having to pay a higher price for imports and foreign holidays. The article linked below examines these effects in more depth.
Just how much the quantity of exports will increase depends on two main things. The first is the amount by which the foreign currency price falls. This depends on what exporters choose to do. Say the pound falls from €1.30 to €1.18. Do exporters who had previously sold a product selling in the UK for £100 and in the eurozone for €130, now reduce the euro price to €118? Or do they put it down by less – say, to €125, thereby earning £105.93 (£(125/1.18)). Their sales would increase by less, but their profit margin would rise.
The second is the foreign currency price elasticity of demand for exports in the foreign markets. The more elastic it is, the more exports will rise for any given euro price reduction.
It is similar with imports. How much the sales of these fall depends again on two main things. The first is the amount by which the importing companies are prepared to raise sterling prices. Again assume that the pound falls from €1.30 to €1.18 – in other words, the euro rises from 76.92p (£1/1.3) to 84.75p (£1/1.18). What happens to the price of an import to the UK from the eurozone whose euro price is €100? Does the importer raise the price from £76.92 to £84.75, or by less than that, being prepared to accept a smaller profit margin?
The second is the sterling price elasticity of demand for imports in the UK. The more elastic it is, the more imports will fall and, probably, the more the importer will be prepared to limit the sterling price increase.
The article also looks at the effect on aggregate demand. As we saw in the previous blog, a depreciation boosts aggregate demand by increasing exports and curbing imports. The effects of this rise in aggregate demand depends on the degree of slack in the economy and the extent, therefore, that (a) exporters and those producing import substitutes can respond in terms of high production and employment and (b) other sectors can produce more as multiplier effects play out.
Finally, the article looks at the effect of the depreciation of sterling on asset prices. UK assets will be worth less in foreign currency terms; foreign assets will be worth more in sterling. Just how much the prices of internationally traded assets, such as shares and some property, will change depends, again, on their price elasticities of demand. In terms of assets, there has been a gain to UK balance sheets from the depreciation. As Roger Bootle says:
Whereas the overwhelming majority of the UK’s liabilities to foreigners are denominated in sterling, the overwhelming bulk of our assets abroad are denominated in foreign currency. So the lower pound has raised the sterling value of our overseas assets while leaving the sterling value of our liabilities more or less unchanged.
