The price of road fuel is falling. Petrol and diesel prices in the UK are now at their lowest level since February 2011. The average pump price for a litre of unleaded petrol has fallen to 130.44p in November – down nearly 8p per litre since September.

According to the AA, the reduction in price equates to a fall in the average monthly expenditure on petrol of a two-car family of £14.49 – down from £252.54 to £238.05. This saving can be used for spending on other things and can thus help to boost real aggregate demand. The fall in price has also helped to reduce inflation.

But will lower fuel prices lead to a rise in fuel consumption? In other words, will some of the savings people make when filling up be used for extra journeys? If so, how much extra will people consume? This, of course depends on the price elasticity of demand.

The following articles explain why the price of road fuel has fallen and look at its consequences.

Compared with pre-financial crisis levels, the British pound is significantly weaker when measured against a basket of foreign currencies. In this blog we provide a further update of Appreciating a depreciating pound which was published back in early December 2012. The significance of the depreciation should be seen in the context of the UK as an open, island-economy where the ratio of exports to GDP in 2012 was close to 32%.

The competitiveness of our exports is, in part, affected by the exchange rate. Floating exchange rates are notoriously volatile. For example, some of the articles below show how sensitive the British pound can be latest news on the economy. However, since the autumn of 2007 we have observed a significant depreciation of the UK exchange rate. A depreciation helps to make our exports more competitive abroad and can potentially boost aggregate demand.

Rather than simply focus on bilateral exchange rates and so at the British pound separately against other foreign currencies, we can estimate an average exchange rate against a whole bundle of currencies. The average rate is calculated by weighting the individual exchange rates by the amount of trade between Britain and the other countries. This trade-weighted exchange rate is known as the effective exchange rate.

In analysing the competitiveness of the exchange rate, we can go one step further and adjust for the average (domestic currency) price of our exports relative to the average (foreign currency) price of those goods we import. Therefore, as well as the nominal (actual) effective exchange rate we can calculate a real effective exchange rate. If the average price of our exports rises relative to the average price of imports, the real effective exchange rate rises relative to the nominal rate. It means that we are able to obtain a larger volume of imports from selling a given volume of exports.

The chart shows the nominal (actual) and real effective exchange rate for the British pound since 2001. The chart shows clearly how from the autumn of 2007 the effective exchange rate fell sharply both in nominal and real terms.

Over the period from July 2007 to January 2009 the nominal effective exchange rate fell by 26.8 per cent while the real effective exchange rate fell by 26.6 per cent. In other words, the British pound depreciated more than one-quarter over an 18-month period. In comparison, the American dollar rose by 5.3 per cent in nominal terms and by 1.9 per cent in real terms. (Click here to download a PowerPoint of the chart.)

If we move the clock forward, we observe an appreciation of the British pound between July 2011 and September 2012. Over this period, the British pound appreciated by 7.0 per cent in nominal terms and by 7.3 per cent in real terms. However, this appreciation had effectively been wiped-out when by March 2013 the nominal rate had depreciated by 6.1 per cent and by 5.6 per cent in real terms. Subsequently, there has been a slight appreciation once more. As of September, the nominal rate had risen by 4.5 per cent and the real rate by 4.8 per cent.

While, as recent figures help to demonstrate, the British pound continues on its roller-coaster ride, there has been a very marked depreciation since the giddy-days prior to the financial crisis. The facts show that when comparing the effective exchange rate in September 2013 with July 2007 the British pound was 21.8 per cent lower in nominal terms and 18.3 per cent in real terms. Over the same period, the US dollar, for example, was only 1.3 per cent lower in nominal terms and 6.1 per cent in real terms. This constitutes a major competitive boost for our exporters. Nonetheless, there remain uncertainty about just how much British exporters can take advantage of this, the amount that it will boost British growth and the impact it will make on the country’s chronic balance of trade deficit in goods which was close to 7 per cent of GDP in 2012.

The rate of growth in India has fallen to its lowest level since the first three months of 2009 – the period when many countries were plunging into recession. Although the annual rate was still 4.4% in Q2 2013 (a rate most Western governments would love to achieve!), it had averaged 8.2% from 2003 to 2007 and 9.5% from 2010 to 2011 (see).

And the rupee has been falling in value (see chart below). The exchange rate of the rupee to the dollar has depreciated by 21% since the start of the year and by 14% since the beginning of August (click here for a PowerPoint of the chart). This has pushed up the price of imports and raised fears that inflation, already approaching 10%, will rise.

There have also been concerns about the health of India’s banking sector, with worries over the possible rise in bad loans.

One result of all these factors is that the confidence of investors has been shaken. Bond prices have fallen and so too have share prices. The Mumbai Sensex index fell by 11.5% from 22 July to 27 August. Worried about possible capital flight, the Indian government imposed capital controls on Indian residents on 14 August. It has, however, since ruled out limiting the outflow of funds by foreign investors.
