Exchange Rate Fluctuations (SPICED), Free Trade vs Protectionism & Current Account

1

International Trade, Exports & Imports

Exports are goods and services produced domestically (in the UK) and sold to buyers in other countries (bringing money into the country). Imports are goods and services produced overseas and bought by domestic (UK) residents and firms (sending money out of the country). Free trade (trade without tariffs or quotas) gives consumers lower prices and wider choice, allows firms to exploit economies of scale in a global market, and increases world output via specialisation.

The Exchange Rate & Currency Conversions

The exchange rate is the value of one currency expressed in terms of another currency (e.g., £1 = €1.18). Determined by the interaction of demand for Pounds (from foreigners buying UK exports, visiting the UK as tourists, or saving in UK banks when UK interest rates rise) and supply of Pounds (from UK residents buying foreign imports, holidaying abroad, or investing overseas). Rule: £ to Foreign = Multiply by rate; Foreign to £ = Divide by rate.

Appreciation (SPICED) vs Depreciation (WPIDEC)

1. Appreciation (Strong Pound: Imports Cheap, Exports Dear): The value of £1 rises against other currencies. UK exports become more expensive for foreign buyers (quantity demanded of exports falls), while foreign imports become cheaper for UK buyers (imports rise, worsening the trade balance, but reducing imported cost-push inflation for UK firms buying foreign raw materials). 2. Depreciation (Weak Pound: Imports Dear, Exports Cheap): The value of £1 falls. UK exports become cheaper abroad (export sales rise, creating UK jobs and improving the current account), while imports become more expensive (causing cost-push inflation).

The Current Account of the Balance of Payments

Records all payments for trade in goods (visibles), trade in services (invisibles), primary income (investment profits/dividends/interest), and secondary income (government foreign aid and worker remittances). Current Account Balance = Total Credits (money inflows): Total Debits (money outflows). If Credits > Debits, there is a Current Account Surplus; if Debits > Credits, there is a Current Account Deficit.

Causes & Consequences of a Current Account Deficit

Causes of a persistent UK Current Account Deficit: 1. Deindustrialisation (loss of UK manufacturing means the UK must import cars, electronics, and clothing). 2. Low labour productivity / poor quality or high inflation relative to competitors (making UK exports uncompetitive). 3. A strong exchange rate (SPICED). 4. High domestic consumer spending sucking in imports. Consequences: Can indicate uncompetitive domestic industries, reduces Aggregate Demand and jobs in export sectors, and must be financed by borrowing from abroad or selling UK assets, which can weaken confidence in the Pound.

Globalisation: Drivers, Benefits & Costs

Globalisation is the process of increasing integration and interdependence of the world's economies through cross-border trade, capital flows, migration, and technology. Driven by: containerisation (cheap shipping), internet/communications, removal of trade barriers (WTO), and the growth of Multinational Corporations (MNCs/TNCs). In developed countries (HICs), consumers benefit from cheap imported goods and skilled workers gain high-paid finance/tech jobs, while low-skilled manufacturing workers suffer structural unemployment. In developing countries (LICs/NEEs), FDI creates millions of factory jobs and reduces extreme poverty, though it can cause sweatshop exploitation and environmental pollution.

1. Q1

   A British bicycle manufacturer imports carbon-fibre frames from Taiwan priced at $300 each, and exports finished bicycles to the USA at a UK price of £1,200 each. The exchange rate falls from £1 = $1.50 to £1 = $1.20. (a) Calculate the change in the £ cost of importing one frame, and the change in the $ price of one exported bicycle. (b) Explain how this exchange rate change affects the firm's costs and export sales. [5 marks]

(a) Import cost in £ (divide $300 by rate): At £1 = $1.50, cost = 300 ÷ 1.50 = £200; at £1 = $1.20, cost = 300 ÷ 1.20 = £250 (import cost rises by £50 per frame) [1 mark]. 2. Export price in $ (multiply £1,200 by rate): At £1 = $1.50, price = 1,200 x 1.50 = $1,800; at £1 = $1.20, price = 1,200 x 1.20 = $1,440 (export price falls by $360 per bicycle) [1 mark]. 3. (b) The fall in the exchange rate from $1.50 to $1.20 is a depreciation of the Pound (Weak Pound: Imports Dear, Exports Cheap - WPIDEC) [1 mark]. 4. Because imported carbon-fibre frames now cost £50 more each in Sterling, the manufacturer's variable costs of production increase, squeezing its profit margins (or forcing it to raise UK prices) [1 mark]. 5. However, because the finished bicycle is now $360 cheaper for American customers, the firm is much more price-competitive in the US market, so the quantity of bicycles exported to the USA should increase [1 mark].

2. Q2

   The UK has experienced a persistent deficit on the Current Account of its Balance of Payments for over twenty years. Explain two causes of the UK's Current Account deficit, and evaluate whether a depreciation of the Pound is the best way to reduce this deficit. [6 marks]

   Click “Check Mark Scheme” to compare your answer, 1. Cause 1 (Deindustrialisation & Structural shift): Over recent decades, the UK's manufacturing sector has shrunk while countries like China and Germany enjoy lower unit costs or higher productivity; consequently, the UK must import vast quantities of manufactured consumer goods (cars, clothing, electronics), creating a massive deficit on Trade in Goods that outweighs the UK's surplus on financial Services [1 mark]. 2. Cause 2 (Consumer spending & Low productivity): High UK household propensity to spend on imported goods combined with lower UK labour productivity and higher domestic inflation makes UK exports less competitive abroad [1 mark]. 3. How depreciation helps (WPIDEC): A depreciation (fall) in the value of the Pound makes UK exports cheaper in foreign currencies and makes foreign imports more expensive in Pounds, encouraging foreigners to buy more UK exports and UK consumers to switch to domestic goods [1 mark]. 4. Limitation 1 (Inelastic demand for imports): However, UK demand for many imports (such as crude oil, gas, food, and essential electronic components that are not made in the UK) is price inelastic; if the Pound falls, the UK still has to buy these imports at higher £ prices, which can actually worsen the import bill and cause cost-push inflation [1 mark]. 5. Limitation 2 (Non-price factors): If UK exports suffer from poor reliability, lack of innovation, or insufficient factory capacity, a cheaper currency will not persuade foreign buyers to switch in the long run [1 mark]. 6. Evaluation (Supply-side alternative): Therefore, while a weaker Pound provides a short-term boost to exporters, the best long-term solution to a structural Current Account deficit is Supply-Side Policy (investing in R&D, green technology, infrastructure, and skills training) to raise UK productivity and export quality without causing inflation [1 mark].

Benefits for consumers (Lower prices & Choice): Globalisation allows UK consumers to buy goods manufactured in lower-wage economies (like China, Vietnam, and Bangladesh) and out-of-season foods from around the world, significantly lowering the price of clothing, electronics, and food (increasing real disposable income and living standards) while expanding consumer choice [1 mark]. 2. Benefits for UK producers (Larger markets & Cheaper inputs): UK businesses (especially in pharmaceuticals, aerospace, higher education, and financial services) can export to billions of new middle-class consumers in emerging markets, achieving economies of scale, while sourcing cheaper raw materials and components globally [1 mark]. 3. Benefits for skilled workers & inward FDI: Globalisation attracts foreign Multinational Corporations (such as Nissan in Sunderland or tech firms in London) to invest in the UK, creating high-paid jobs, and enables firms to fill UK skill shortages (e.g., NHS nurses and software engineers) through international migration [1 mark]. 4. Costs for low-skilled UK workers (Structural unemployment): However, UK factories cannot compete with much lower unit labour costs in developing nations, causing deindustrialisation as manufacturing relocates abroad ('offshoring') and leaving former industrial towns with structural unemployment and depressed wages [1 mark]. 5. Costs for domestic producers (Intense competition & Supply chain vulnerability): Small UK manufacturers face fierce price competition from cheap imports, and globalised just-in-time supply chains leave UK firms vulnerable to global shocks (such as pandemics, wars, or shipping blockages in the Suez/Red Sea) [1 mark]. 6. Conclusion: Overall, globalisation generates a net economic gain for the UK as a whole (cheaper goods and booming service exports), but its costs fall heavily on low-skilled manufacturing workers, requiring government retraining and regional investment to support left-behind regions [1 mark].

4. Q4

   Explain why a government might choose to restrict free trade by placing protectionist tariffs on imported goods (such as imported electric cars or steel), and state two disadvantages of doing so. [4 marks]

   Check Mark Scheme

   Click “Check Mark Scheme” to compare your answer, 1. Reason 1 (Protecting domestic jobs & Infant/strategic industries): A tariff is a tax on imported goods that raises their price; this encourages domestic consumers to switch from foreign imports to domestically produced steel or electric cars, protecting domestic jobs from structural unemployment and allowing new domestic 'infant industries' to grow [1 mark]. 2. Reason 2 (Improving the Current Account & Preventing 'dumping'): Tariffs reduce the volume of imports entering the country (improving the Trade in Goods balance) and stop foreign producers who receive state subsidies from 'dumping' goods below cost to bankrupt domestic firms (plus tariffs raise tax revenue for the government) [1 mark]. 3. Disadvantage 1 (Higher prices & Cost-push inflation): Tariffs force domestic consumers to pay higher prices for imported cars and goods, and raise production costs for domestic firms that use imported steel as a raw material [1 mark]. 4. Disadvantage 2 (Retaliation / Trade war): Other countries will likely retaliate by placing their own tariffs on the country's exports, reducing export sales and hurting export industries [1 mark].
