at the end of the lesson u should be able to: understand • meaning of exchange rate (ER) • meaning of Nominal ER • meaning and formula of Effective ER • meaning of Trade Weighted ER • calculate Trade Weighted ER • meaning of Real ER • identify items that create a demandfor a currency • identify items that create a supply for a currency
Exchange Rate • Price of one currency in terms of another • The rate at which one currency can be exchanged for another e.g. • £1 = $2.00 • £1 = €1.50
£ Supose exchange rate is $2.00/ £ £ 10 40,000 $20 $80,000
Nominal exchange rate • ER of £1 =RM5.80 means need RM5.80 to buy £1 • are quoted in national newspapers • Since one currency is expressed against another, nominal ERs are bilateral rates. • €/$ • £/$ • ¥/$
Effective Exchange Rate • measures the value of a currency against a basket/group of currencies • multilateral rate • Trade Weighted Exchange Rate is used • in index form • the weight accorded to each currency depends on the proportion of trade done with the country. • the larger the size of the trade, the larger the weightage.
The weights of the currencies of various countriesin the sterling exchange rate index
Trade WeightedIndex (TWI) • UK’s trade with US – 70% trade with France – 30% • If £ 10% against USD • £ 20% against € • % = (-10% x 0.7) + (-20% x 0.3) = - 7% - 6% = - 13% TWI = 100 - 13 = 87
Real Effective ER • Real ER takes price changes into account • = effective ER X Domestic Price level Foreign Price level
DD & SS of Currencies • Exchange rates are determined by the demand for and the supply of currencies on the foreign exchange market (forex) • The demand and supply of currencies is in turn determined by: • International Trade in G & S • Investments • Speculation
