The sharp fall in sterling over the past three years and the nascent signs of recovery in the global economy provide an opportunity for growth that the UK cannot afford to miss. With the household and corporate sectors weighed down by high levels of indebtedness, and the public sector about to embark on a substantial fiscal squeeze, the prospect of a meaningful recovery in domestic demand over the coming years is, we believe, limited. Instead, to achieve a reasonably strong and sustained rate of growth means it is not only desirable, but essential, that the UK rebalances away from debtdriven domestic demand towards net exports. The competitive boost provided by the fall in sterling, and the steady recovery in global demand, provide this opportunity.

Since peaking in January 2007, sterling’s tradeweighted index has fallen by around twenty-five percent. While the trade-weighted exchange rate has recovered a little over the past year, the overall decline over the past three years represents the largest correction in the exchange rate since the UK withdrew from the ERM in the early 1990s. As chart a shows, the decline in sterling has been most acute against the yen, with GBP/YEN having dropped by around almost 70% over this period. Nonetheless, against the US dollar, euro, Swiss franc, and a host of emerging market currencies, sterling has also fallen sharply.

To the extent that a fall in the exchange rate raises import prices and lowers export prices, one might expect the fall in sterling to be associated with a marked improvement in the UK’s trade position (the difference between the amount we export and import, in current prices). But, as chart b shows, the improvement in the UK’s trade balance in recent years has been relatively modest.

Since early 2007, the UK’s total trade deficit in goods and services as a proportion of gdp has improved by just over 1 percentage point (pp) to 2.2%, driven by a reduction in the visible (goods) trade deficit. While the current trade deficit is not out of line with the experience of the last decade, it remains troubling that the UK export sector has not yet responded more strongly to the fall in the exchange rate, particularly given the fragile backdrop to domestic demand. This is particularly so, as a large part of the improvement in the UK’s trade deficit has been the result of a sharp fall in imports, reflecting weak demand conditions at home. This source of improvement cannot be sustained indefinitely, and a meaningful recovery in the UK’s export performance will be required if the trade balance is ultimately to move back into surplus territory - as it did briefly in the mid-1990s, following sterling’s exit from the ERM.

So why has the UK’s trade position not improved more sharply? Part of the reason may be that the competitive boost has occurred against the currencies of those countries which undertake relatively little trade with the UK (see chart c). For example, UK exports to Japan, Switzerland and Brazil account for only 4% of total exports.

However, against the currencies of our largest trading partners - the major euro zone countries and the US - the drop in the exchange rate has still been substantial. Against the euro and US dollar, sterling has dropped by around 25-30% since earlty 2007 - far more than it has against many of the developing economy currencies. It seems that rather than increasing market share, therefore, UK exporters have used the opportunity of the weaker exchange rate to rebuild profit margins. Indeed, over the past three years, export prices have risen by almost 25% (se chart d).

The UK’s terms of trade is the ratio of its export prices to its import prices. As such, it measures how many units of imports the UK can buy with one unit of exports.

Other things being equal, a fall in the exchange rate might be expected to lead to a deterioration (i.e. fall) in the UK’s terms of trade, as import prices rise and export prices fall (and vice versa). As chart d shows, however, the UK’s terms of trade has actually improved slightly over the past three years. In other words UK export prices have risen relative to import prices, despite the fall in sterling’s exchange rate over this period. The improvement in the terms of trade, it seems, has limited the recovery in UK export volumes.

The experience of the past three years contrasts with the experience of the UK in the early 1990s, when export volumes responded more aggressively to the fall in the exchange rate. Indeed, it was the boost to UK net trade during this period that was instrumental in raising real incomes and bringing the UK out of recession. It remains to be seen whether the same will occur this time around. It may not if export prices do not fall.

However, the lags between exchange rate movements impacting on trade volumes can be substantial. Companies, for example, may be locked in to multiyear fixed price contracts; they may be wary about lowering their export prices for fear that the decline in the exchange rate could be short-lived; and/or they may need to widen margins to help protect their balance sheets.

Notwithstanding the above, we are hopeful that the UK will respond to the opportunities that arise from the fall in sterling and the signs of global economic recovery. Indeed, the marked improvement in the export orders balances of the latest CBI SME Trends and manufacturing PMI surveys provide grounds for optimism. According to the January PMI survey, manufacturing export orders are currently at their highest level since this data were collected in 1996.

Although the share of manufacturing in gdp has fallen markedly over the past thirty years, there remain many industries, in both the goods and services sectors, in which the UK has a comparative advantage - chemicals, business & financial services, engineering and biosciences, to name but a few. If the UK is emerge from the downturn with a stronger and more stable economy over the medium to longer term, it is essential that this rebalancing away from domestic consumption towards net exports occurs.
