4.6.4 Policies to Correct Imbalances

Addressing the nuances of balance of payments (BOP) imbalances is fundamental for maintaining economic stability and sustaining growth, involving meticulous applications of monetary policy, fiscal policy, and exchange rate adjustments.

Monetary Policy

Monetary policy, orchestrated by a country’s central bank, aims to regulate the money supply within an economy, with the objectives of maintaining price stability and sustaining high levels of economic growth and employment.

Interest Rate Adjustments

Interest rates are paramount in regulating foreign investment flows and currency values.

  • Increasing Interest Rates: By elevating interest rates, countries can allure foreign capital, enhancing the financial account and potentially mitigating a BOP deficit.
    • Benefits:
      • Foreign Investment: Increased interest rates can attract foreign investors seeking higher returns.
      • Currency Appreciation: A stronger currency can decrease the cost of imports and elevate export prices.
    • Drawbacks:
      • Economic Slowdown: Higher borrowing costs can suppress domestic investment and consumption, leading to reduced economic activity.
      • Unemployment: Reduced economic activity can result in increased unemployment.
  • Decreasing Interest Rates: A reduction in interest rates can discourage foreign capital inflows, mitigating a BOP surplus.
    • Benefits:
      • Domestic Investment: Lower borrowing costs can stimulate domestic investment and consumption.
      • Currency Depreciation: A weaker currency can augment the competitiveness of domestic exports and elevate the cost of imports.
    • Drawbacks:
      • Inflationary Pressures: Elevated demand due to increased spending can instigate inflation.
      • Asset Bubbles: Excessive liquidity can lead to the formation of asset bubbles in property and stock markets.

Money Supply Control

Control over the money supply is crucial for maintaining economic stability.

  • Contractionary Monetary Policy: By reducing the money supply, countries can appreciate their domestic currency and improve the BOP.
    • Impact:
      • Reduced Inflation: A smaller money supply can curtail inflationary pressures.
      • Reduced Aggregate Demand: Contraction in money supply can lead to reduced consumption and investment.
  • Expansionary Monetary Policy: Increasing the money supply can depreciate the domestic currency and support export competitiveness.
    • Impact:
      • Increased Inflation: An augmented money supply can induce inflation.
      • Elevated Aggregate Demand: Expansion in money supply can boost consumption and investment.

Fiscal Policy

Fiscal policy employs adjustments in government spending, taxation, and borrowing to rectify imbalances in the BOP, affecting aggregate demand, economic activity, and trade balances.

Government Spending

  • Reducing Government Expenditure: Curtailing government spending can alleviate a deficit in the BOP by reducing aggregate demand and import expenditure.
    • Impact:
      • Economic Contraction: Can lead to reduced economic activity and employment.
      • Improved Current Account: Lower import volumes can ease pressures on the current account.
  • Increasing Government Expenditure: Escalating government spending can counter a surplus by boosting aggregate demand and import expenditure.
    • Impact:
      • Economic Expansion: Can stimulate economic activity and employment.
      • Worsened Current Account: Elevated import volumes can intensify pressures on the current account.


  • Increasing Taxes: Augmenting tax rates can help rectify a deficit in the BOP by diminishing disposable income and import demand.
    • Impact:
      • Reduced Consumption: Lower disposable income can suppress consumer spending and import volumes.
      • Improved Trade Balance: Reduced import demand can ameliorate the trade balance.
  • Reducing Taxes: Lowering taxes can address a surplus by increasing disposable income and import demand.
    • Impact:
      • Boosted Consumption: Enhanced disposable income can spur consumer spending and import volumes.
      • Deteriorated Trade Balance: Augmented import demand can impair the trade balance.


  • Reducing Borrowing: A decline in government borrowing can elevate interest rates and attract foreign capital, thereby improving the financial account.
    • Impact:
      • Attracted Foreign Capital: Higher interest rates can draw foreign investors.
      • Suppressed Domestic Investment: Elevated borrowing costs can hamper domestic investment.
  • Increasing Borrowing: An uptick in government borrowing can depress interest rates, dissuading foreign capital inflows and addressing a surplus in the financial account.
    • Impact:
      • Detracted Foreign Capital: Lower interest rates can repel foreign investors.
      • Stimulated Domestic Investment: Reduced borrowing costs can encourage domestic investment.

Exchange Rate Adjustments

Exchange rate adjustments are pivotal in rectifying BOP imbalances, affecting the competitiveness of domestic goods and the cost of imports.


  • Objective: To ameliorate a BOP deficit
    • Method: A deliberate reduction in the value of the domestic currency renders exports cheaper and imports pricier.
    • Impact:
      • Enhanced Trade Balance: Augmented export competitiveness and reduced import volumes improve the trade balance.
      • Inflationary Pressures: More expensive imports can instigate inflation.

  • Objective: To mitigate a BOP surplus
    • Method: An intentional elevation in the value of the domestic currency makes exports pricier and imports cheaper.
    • Impact:
      • Impaired Trade Balance: Diminished export competitiveness and augmented import volumes deteriorate the trade balance.
      • Deflationary Pressures: Cheaper imports can induce deflation.

Managed Float

  • Objective: To maintain stability in exchange rates
    • Method: Central banks strategically intervene in foreign exchange markets to modulate the value of their currency.
    • Impact:
      • Exchange Rate Stability: Managed float can smoothen excessive exchange rate volatility, maintaining international competitiveness.
      • Preserved Foreign Reserves: Strategic interventions can help sustain foreign reserves, crucial for economic stability.

Fixed Exchange Rate Adjustments

  • Objective: To uphold a predetermined exchange rate
    • Method: Central banks leverage their foreign currency reserves to modulate the domestic currency’s value in the forex market.
    • Impact:
      • Stable Exchange Rates: Ensures predictability and stability in international trade.
      • Reserve Depletion Risks: Unsustainable interventions can lead to the exhaustion of foreign reserves, jeopardising economic stability.

The judicious and harmonious implementation of these policies is paramount for effectively rectifying BOP imbalances and fostering long-term economic prosperity and stability. Policy formulations should be meticulous, taking into account the prevailing economic conditions and potential ramifications, to ensure the efficacy and sustainability of economic interventions.


While monetary policy plays a critical role in addressing imbalances in the balance of payments by influencing interest rates and exchange rates, it often needs to be complemented with other policies for holistic economic stability. Effective coordination with fiscal policy is essential to manage government expenditure and taxation optimally. Structural reforms might be necessary to improve competitiveness and productivity, and trade policies can be adjusted to control the flow of imports and exports effectively. A multi-faceted approach ensures sustainable corrections in the balance of payments.

Managing exchange rates can address imbalances in the balance of payments by controlling the prices of exports and imports. A devalued currency can enhance export competitiveness and discourage imports, improving the trade balance. However, the drawbacks include possible retaliatory devaluations by trade partners and the risk of imported inflation due to higher prices of foreign goods and services. Furthermore, constant intervention in the foreign exchange market might lead to diminishing foreign exchange reserves and could undermine investor confidence due to perceived economic instability.

A balance of payments surplus implies that a country receives more money from abroad than it sends out. This can lead to an appreciation of the country's currency, making exports less competitive and imports cheaper. While it can help control inflation, it might impact domestic industries adversely. Appropriate policies to mitigate the impacts include expansionary fiscal policy to stimulate domestic demand and counteract the impacts of currency appreciation on exports and controlled intervention in the foreign exchange market to manage excessive currency appreciation.

Fiscal policy, encompassing government spending and taxation, influences the capital account by altering domestic investment levels. When government increases spending or reduces taxes, it can stimulate domestic economic activity, potentially attracting foreign direct investment, leading to a surplus in the capital account. However, excessive government expenditure might necessitate borrowing, impacting interest rates and possibly leading to capital flight, resulting in a deficit in the capital account. Hence, fiscal policy requires meticulous management to avoid undesired implications on the capital account in the balance of payments.

When a currency depreciates, the cost of imports becomes more expensive, leading to imported inflation. This can impact consumer spending, reducing the real income of individuals, and may lead to a contraction in aggregate demand if it leads to increased prices overall. On the other hand, a cheaper currency can stimulate exports as domestic goods and services become more competitively priced for foreign buyers, potentially improving the trade balance and thereby positively impacting the current account in the balance of payments.

Practice Questions

Evaluate how an increase in government borrowing can potentially impact the balance of payments, addressing both the financial and current account.

An adept increase in government borrowing can lead to a reduction in interest rates due to the increased supply of money in the economy, potentially deterring foreign investment and affecting the financial account adversely. This translates to a surplus in the domestic money market and thus, can lead to depreciation of the domestic currency, fostering export competitiveness. Consequently, the current account may witness improvement due to increased demand for relatively cheaper domestic goods. However, cheaper currency can increase import costs, causing inflationary pressures. Thus, a nuanced understanding of the economic context is essential for leveraging government borrowing effectively.

Discuss the implications of a contractionary monetary policy on a country experiencing a deficit in the balance of payments, focusing on the effects on the currency value and trade balance.

A contractionary monetary policy, marked by a reduction in money supply and elevated interest rates, can alleviate a deficit in the balance of payments by appreciating the domestic currency value. An appreciated currency makes domestic goods relatively more expensive, potentially reducing export volumes and improving the import bill by making foreign goods cheaper. However, this could exacerbate the trade balance, as decreased export competitiveness might suppress export revenues. Nevertheless, higher interest rates could attract foreign capital inflows, improving the financial account. Hence, while contractionary policy can address imbalances, its impact on trade balance necessitates cautious implementation.
