This module explains the causes of persistent current account deficits and surpluses, and explores policy options to correct imbalances, including their impacts on domestic growth, inflation and employment.

**Prerequisites:** [Balance of Payments Accounting](https://www.owlsprep.com/study/cie-9708-u8-balance-of-payments/); [Exchange Rate Systems](https://www.owlsprep.com/study/cie-9708-u8-exchange-rate-systems/)

## Learning objectives

- Distinguish between current account deficits and surpluses, and identify their root causes
- Categorize correction policies into expenditure-switching and expenditure-reducing types
- Evaluate the advantages and disadvantages of each policy type for correcting imbalances
- Analyze trade-offs between correcting imbalances and meeting other macroeconomic objectives

## Nature and Causes of Current Account Imbalances

**Current account imbalance** — A persistent deviation from current account balance, where the value of exports plus net income flows does not equal the value of imports over multiple years. This can be a deficit (outflows exceed inflows) or a surplus (inflows exceed outflows).

*Example:* The US has run a persistent current account deficit since the 1990s, while China has run a persistent surplus over the same period.

Imbalances arise from a range of demand-side and supply-side factors, connected to a country's exchange rate, inflation rate, productivity, and growth rate. Common causes of deficits include overvalued exchange rates, higher domestic inflation than trading partners, low productivity, and strong economic growth that increases import demand.

**Worked example:** Explain why a country with a fixed exchange rate and persistent higher inflation than its trading partners will likely develop a current account deficit.

1. Higher domestic inflation increases the price of domestically produced exports relative to goods from lower-inflation trading partners.
2. This reduces foreign demand for exports, lowering export revenue, and makes imports relatively cheaper than domestic goods for domestic consumers.
3. Higher import volumes and lower export volumes lead to a fall in net trade (X-M), ceteris paribus, resulting in a current account deficit.

> **Exam tip:** Always link the cause of an imbalance to the policy solution you suggest in exam answers.

## Expenditure-Switching Policies

**Expenditure-switching policy** — Policy that aims to change the composition of domestic spending, switching demand away from imports towards domestically produced goods, and increasing foreign demand for domestic exports.

The main examples of expenditure-switching policies are currency devaluation (for fixed exchange rates) or depreciation (floating rates), and trade protectionism (tariffs, quotas on imports). These policies work by changing the relative price of imports and exports.

> Devaluation will only improve the current account if the Marshall-Lerner condition is met: the sum of the price elasticity of demand for exports and imports must be greater than 1.

**Worked example:** Evaluate the impact of a currency devaluation on correcting a current account deficit.

1. Devaluation lowers the foreign currency price of exports and raises the domestic price of imports, switching domestic and foreign spending towards domestic goods.
2. If the Marshall-Lerner condition is satisfied, net trade improves, reducing the current account deficit.
3. In the short run, the J-curve effect means the deficit may worsen first, because trade volumes take time to adjust to price changes.
4. Disadvantages: Higher import prices cause cost-push inflation, and may reduce pressure on domestic firms to improve productivity.

## Expenditure-Reducing Policies

**Expenditure-reducing policy** — Contractionary fiscal or monetary policy that reduces overall aggregate demand in the economy, leading to lower import spending because consumers and firms have less income to spend on foreign goods.

When a current account deficit is driven by strong domestic growth and high import demand, governments can use tax increases, spending cuts, or higher interest rates to slow down aggregate demand and reduce import consumption.

**Worked example:** A country has a current account deficit of 5% of GDP and high domestic inflation. Explain how contractionary fiscal policy can correct the deficit.

1. Contractionary fiscal policy cuts government spending or raises taxes, reducing household disposable income and firm profits.
2. Lower income reduces overall consumption and investment, including spending on imported goods and services, so import expenditure falls.
3. Lower aggregate demand also reduces domestic inflation, improving the international competitiveness of domestic exports over time.
4. Trade-off: Lower AD leads to slower economic growth and higher cyclical unemployment, which is politically unpopular.

## Supply-Side Policies for Long-Term Correction

Persistent current account deficits are often caused by long-term lack of competitiveness, from low productivity, high production costs, or poor infrastructure. Supply-side policies address these root causes to improve export performance and reduce import demand over time.

- Investment in education and infrastructure to lower production costs
- Labor market reform to increase flexibility and reduce wage costs
- Deregulation and tax cuts for firms to encourage investment and innovation

**Worked example:** Explain why supply-side policies are often preferred for correcting persistent current account deficits compared to contractionary demand policies.

1. Supply-side policies increase long-run productive capacity, lower production costs, and improve the quality of domestic goods.
2. This increases export competitiveness and reduces demand for cheaper imports, without the negative trade-off of lower growth and higher unemployment associated with expenditure-reducing policies.
3. Disadvantages: Supply-side policies take 5-10 years to have a measurable impact on current account imbalances, and require significant upfront government spending.

## Common pitfalls

- **Wrong:** Assuming all current account deficits are always harmful
  - Why it fails: Many developing countries run temporary deficits to fund productive investment that drives long-term economic growth
  - Correct: Evaluate the size, cause and financing of the deficit before concluding it is problematic
- **Wrong:** Forgetting the Marshall-Lerner condition when analysing devaluation
  - Why it fails: Devaluation will not improve the current account if the sum of elasticities is less than 1
  - Correct: Always reference the Marshall-Lerner condition and J-curve effect in devaluation questions
- **Wrong:** Confusing expenditure-switching and expenditure-reducing policies
  - Why it fails: Examiners require clear categorization of policies to award full marks
  - Correct: Remember: switching changes the composition of spending, reducing cuts the overall level of spending
- **Wrong:** Assuming all current account surpluses are desirable
  - Why it fails: Large persistent surpluses mean the country is consuming less output than it could, and cause trade tensions
  - Correct: Always evaluate the downsides of surpluses as well as deficits in exam answers

## Cheatsheet

| Policy Type | Examples | Key Advantage | Key Disadvantage |
| --- | --- | --- | --- |
| Expenditure-Switching | Currency devaluation | Fast acting if M-L holds | Causes cost-push inflation |
| Expenditure-Switching | Tariffs/quotas | Reduces imports quickly | Risk of retaliation, WTO violation |
| Expenditure-Reducing | Contractionary fiscal policy | Also reduces high inflation | Higher unemployment, slower growth |
| Expenditure-Reducing | Contractionary monetary policy | Reduces import demand quickly | Raises borrowing costs for firms |
| Supply-Side | Infrastructure/education investment | Improves long-term competitiveness | Slow to impact, high fiscal cost |

## What's next

Understanding current account imbalances and correction is core to open-economy macroeconomics, and links to all other topics in international finance and globalisation. Examiners regularly ask you to connect correction policies to broader macroeconomic objectives, like low unemployment, price stability and sustainable growth. Persistent global imbalances are also a key driver of trade disputes and changes to global trade rules, so this topic connects directly to the study of globalisation and development.
