Policies to correct imbalances in the current account of the balance of payments

👋 Welcome to the Current Account Policy Toolkit!

The current account (CA) of the balance of payments acts like a country's trade scorecard. When this score is unbalanced (a large deficit or surplus), governments need to step in.

In this chapter, we explore the powerful tools governments use to fix these imbalances. Don't worry if international economics seems complicated—we’ll break down these policies into simple actions and see their real-world trade-offs!

🧐 Quick Review: What is a Current Account Imbalance?

An imbalance occurs when the total value of money flowing into a country from trade (exports, primary income, secondary income) does not equal the money flowing out (imports, etc.).

• Current Account Deficit: Outflows > Inflows. The country is buying more than it is selling internationally. This must be funded by borrowing or selling off financial assets (Financial/Capital Account surplus).
• Current Account Surplus: Inflows > Outflows. The country is exporting more than it is importing. While seemingly good, a sustained large surplus can cause inflationary pressure and lead to political tensions with trading partners.

The primary government objective here (6.5.1) is stability of the current account, meaning keeping it near balance or correcting chronic deficits and unsustainable surpluses.

Section 1: The Two Key Policy Approaches (6.5.2)

When tackling a current account deficit, governments use two main strategic types of policy. It is vital to distinguish between these two groups, as they aim to solve the problem in fundamentally different ways.

1. Expenditure-Reducing Policies

These policies aim to reduce overall Aggregate Demand (AD) in the economy. Why? Because when people have less income or find it more expensive to borrow, they spend less, and specifically, they buy fewer imported goods.
(Analogy: If your bank account balance goes down, you stop shopping online and buying things from abroad.)

Tools used: Contractionary Fiscal Policy and Contractionary Monetary Policy.

2. Expenditure-Switching Policies

These policies aim to change the pattern of spending. They encourage consumers (domestic and foreign) to buy domestically produced goods instead of imported goods. Total AD might stay the same, but the mix changes.
(Analogy: You still want a new phone, but you decide to buy the local brand instead of the foreign import.)

Tools used: Exchange Rate Adjustments (Depreciation/Devaluation) and Protectionist Measures (tariffs, quotas, subsidies).

Section 2: Policy Effects in Detail (6.5.2)

A. Fiscal Policy

Correcting a Deficit (Expenditure-Reducing): The government uses Contractionary Fiscal Policy.

• Raise Direct Taxes (e.g., Income Tax): Reduces disposable income (\(Y_d\)).
• Cut Government Spending (\(G\)): Directly reduces a component of AD.
• Impact: A fall in AD leads to a fall in national income (\(Y\)). Since imports (\(M\)) depend on income, \(M\) falls, improving the current account balance.

Correcting a Surplus (Expenditure-Increasing): The government uses Expansionary Fiscal Policy (cutting taxes, raising \(G\)) to increase national income, stimulating spending on imports and reducing the surplus.

Evaluation and Trade-offs

• Pro: Can be highly effective in reducing import consumption rapidly.
• Con: Creates policy conflicts! Cutting AD to fix a deficit conflicts with economic growth and low unemployment.
• Analytic Point: If the marginal propensity to import is low, large cuts in AD (risking recession) are needed for only a small current account improvement.

B. Monetary Policy

Correcting a Deficit (Expenditure-Reducing): The Central Bank uses Contractionary Monetary Policy by increasing the rate of interest.

• Higher interest rates increase borrowing costs and reward saving, reducing Consumption (\(C\)) and Investment (\(I\)), shifting AD left.
• Import spending falls as domestic demand contracts, improving the current account balance.

Correcting a Surplus (Expenditure-Increasing): Lowering interest rates boosts domestic spending, increasing import demand and reducing the surplus.

Evaluation and Trade-offs

• Pro: Can be implemented relatively quickly compared to large infrastructure projects.
• Con (Growth/Unemployment Conflict): Contractionary monetary policy slows growth and raises cyclical unemployment.
• Con (Exchange Rate Risk): Higher domestic interest rates attract hot money inflows, causing currency appreciation. This makes exports dearer and imports cheaper, potentially worsening the current account balance over time.

C. Exchange Rate Policy

Correcting a Deficit (Expenditure-Switching): Allowing the currency to depreciate (floating rate) or actively implementing a devaluation (fixed/managed rate).

• A weaker currency makes imports more expensive in local currency (\(M\) falls) and exports cheaper in foreign currency (\(X\) rises), switching spending to domestic goods.

Correcting a Surplus: Currency appreciation or revaluation makes exports more expensive and imports cheaper, reducing the net surplus.

Evaluation: Key Conditions & Time Lags (A Level Link: Topic 11.2.5)

• Marshall-Lerner Condition: For depreciation/devaluation to improve the current account balance, the sum of price elasticities of demand for exports and imports must exceed 1: \(PED_X + PED_M > 1\).
• The J-Curve Effect: In the short run, demands for \(X\) and \(M\) are relatively price-inelastic due to existing contracts and habit persistence. The current account balance may initially worsen before improving over the medium to long run.
• Inflation Risk: Depreciation increases the cost of imported raw materials and consumer goods, risking cost-push inflation.

D. Protectionist Policies

Mechanism: Measures such as tariffs (taxes on imports), quotas (physical limits on imports), or subsidies to domestic producers.

Impact on Current Account: Tariffs and quotas restrict import volumes and raise import prices, while subsidies lower domestic production costs, boosting exports and switching domestic demand to local alternatives.

Evaluation and Trade-offs

• Pro: Directly targets specific deficit-causing imports quickly.
• Con (Retaliation Risk): Trading partners may retaliate with reciprocal trade barriers, harming export sectors.
• Con (Efficiency & Rules): Distorts resource allocation, shields inefficient domestic firms, and may breach international trade commitments.

E. Supply-Side Policies (Long-Term Solution)

Mechanism: Policies that expand productive capacity (shifting LRAS right) and improve quality, productivity, and international competitiveness (e.g., education/training, infrastructure investment, deregulation, and R&D incentives).

Impact on Current Account: Higher productivity and lower unit costs make domestic goods more competitive globally, sustainably increasing exports (\(X\)) and reducing reliance on imports (\(M\)).

Evaluation and Trade-offs

• Pro: Addresses the root structural causes of uncompetitiveness without conflicting with growth or employment goals.
• Con (Time Lag & Cost): Takes years to yield results and incurs high opportunity and fiscal costs.

Section 3: Policy Conflicts and Summary

• Internal vs External Balance: Expenditure-reducing policies (deflating AD) improve the current account but conflict with full employment and economic growth.
• Monetary Policy vs Current Account: Raising interest rates to control inflation can cause currency appreciation, which harms export competitiveness.
• Short-Run vs Long-Run: Expenditure-reducing and protectionist measures provide quick short-term relief with high side effects, whereas supply-side policies provide lasting structural solutions over the long run.
