Chapter 2 Balance of Payments and Current Account — Comprehensive Study Notes

International Flow of Funds — Chapter Objectives

• International Flow of Funds topics: A) Balance of Payments (BOP), B) The international flow of goods and services, C) The international flow of capital, D) Current account deficit.

Balance of Payments (BOP) — Definition and Formula

• BOP is the measurement of all international transactions between residents of a country and foreigners; it records a country’s international economic transactions with the rest of the world.

• Core accounting equation (the BOP): $\text{BOP} = (X - M) + (CI - CO) + (FI - FO) + FXB$

  • $X$ = exports of goods and services

  • $M$ = imports of goods and services

  • $CI$ = capital inflows

  • $CO$ = capital outflows

  • $FI$ = financial inflows

  • $FO$ = financial outflows

  • $FXB$ = official monetary reserves

• BOP encompasses the trade balance, foreign investments, and investments by foreigners.

• It records the value of all goods, services, income and transfers across borders.

• Deficit vs. surplus:

  • Deficit (BOP negative) = more money flowing out than in.

  • Surplus (BOP positive) = more money flowing in than out.

• Example mentions: Malaysia exports palm oil to the US; Malaysia imports chemical products from the US.

Structure of the BOP — Sub-Accounts

• BOP is comprised of three main sub-accounts plus official reserve changes:

  • Current account: records trade in goods and services, income on financial assets, and unilateral transfers.

  • Capital account: records capital transfers (offsets in fixed assets or their financing).

  • Financial account: records net purchases of financial assets (long-term and short-term), including direct investment, portfolio investment, and other investment.

  • FXB (official monetary reserves): official reserve assets/transactions used to balance the BOP.

• Overall BOP identity (reiterated):
  $\text{BOP} = (X - M) + (CI - CO) + (FI - FO) + FXB$

• Current account, capital account, and financial account balances should sum with changes in official reserves to equal zero in a complete BOP statement.

Double-Entry Bookkeeping and the Zero-Balance Property

• BOP follows double-entry bookkeeping: every inflow has a corresponding outflow, so the overall BOP sums to zero when FXB is included.

• Conceptual mapping:

  • Currency inflows are credits (earn foreign exchange).

  • Currency outflows are debits (spend foreign exchange).

• Example (from transcript): A British person sells a painting to a Malaysian resident for RM1,000,000; payment via a cheque drawn on a Malaysian bank.

  • Balance of Payments Debit: Private liability to foreigner RM1,000,000; Malaysian imports RM1,000,000; Debit on Malaysian current account.

  • Balance of Payments Credit: RM1,000,000 of foreign exchange inflow/creditable entry (as a receipt) — illustrating the offsetting nature of the BOP entries.

Current Account

• Current Account records inflows and outflows of goods and services, income on financial assets, and unilateral transfers.

• Components:

  • 1) Merchandise (goods): tangible products moved between countries.

  • Examples: Computers, clothes.

  • 2) Services: non-tangible services crossing borders.

  • Examples: Tourism, legal, insurance, consulting services.

  • 3) Income: receipts/payments on foreign investments (interest, dividends, compensation).

  • 4) Unilateral transfers: one-way transfers with no services rendered (pensions, remittances, humanitarian aid, gifts).

Capital Account

• Capital Account records capital transfers that offset transactions in fixed assets or their financing; considered a minor component.

• Key examples:

  • Debt forgiveness (borrower no longer has to repay).

  • Conditional grants for capital projects (foreign aid to build roads, schools).

  • Transfer of assets between residents and non-residents.

• Capital transfer (definition): one party transfers ownership of an asset to another without receiving something in return.

Financial Account

• Financial Account records net purchases of financial assets.

• It consists of three components:

  • Direct Investment (FDI): ownership/control in a business; management control is exerted (typically at least 10% equity ownership).

  • Portfolio Investment: purchases of long-term financial assets like stocks and bonds that do not entail control over the entity (maturity typically > 1 year).

  • Other Investment: various financial instruments not covered by FDI or portfolio investment (loans, deposits, currency holdings, etc.).

• Summary: Financial Account tracks cross-border capital flows related to ownership of financial assets and changes in financial positions across borders.

Basic BOP Statement — Summary of Major Categories

• Current Account:

  • Balance on goods (exports − imports)

  • Balance on services (exports − imports)

  • Income receipts/payments

  • Unilateral transfers (receipts − payments)

• Capital Account:

  • Capital transfers (receipts − payments)

• Financial Account:

  • Portfolio investment (in the U.S./overseas) – credit and debit entries

  • Direct investment (in the U.S./overseas) – credit and debit entries

  • Government investment (in the U.S./overseas)

  • Changes in reserve assets

• Additional aggregates often shown:

  • Balance on reserve assets, balance on other investments, balance on financial assets, balance on current account, and the overall balance (surplus or deficit)

• An overall balance includes a statistical discrepancy to reconcile measurement differences.

Basic BOP Definitions — Balance Concepts

• Basic balance: transactions fundamental to the currency’s health; includes the current account and long-term capital accounts but excludes ephemeral items.

• Official reserve transactions balance: measures adjustment required in official reserves to achieve BOP equilibrium.

Usefulness and Policy Relevance of the BOP

• Governments use BOP to:

  • Measure economic activity and competitiveness of domestic industries.

  • Inform exchange rate and interest rate policies; set goals for macro policy.

  • Estimate growth and health of trade/financial transactions by country and region.

  • Anticipate changes in host country policies driven by BOP dynamics.

Macroeconomic Identities — Linkages Across Accounts

• Core identities link spending, production, savings, and investment to CA and FA balances.

• Domestic income and expenditure relations:

  • National Income: $NI = C + S$ where $C$ is consumption and $S$ is savings.

  • National Expenditures: $NE = C + I$ where $I$ is investment.

  • Therefore: $NI - NE = S - I$ (Identity 5.1)

• Exports and imports relation:

  • National Income in terms of output and exports: $NI = ( ext{domestic goods/services}) + X$

  • National Expenditure in terms of output and imports: $NE = ( ext{domestic goods/services}) + M$

  • Therefore: $NI - NE = X - M$ (Identity 5.2)

• Combining (5.1) and (5.2):

  • $S - I = X - M$ (Identity 5.3)

  • This links the current account (via exports/imports) to the financial account (via net foreign investment).

• Current Account and Financial Account linkage (Identity 5.4 to 5.6):

  • Current Account balance equals Exports − Imports:
    $CA = X - M$

  • Net Foreign Investment (NFI) equals Exports − Imports:
    $NFI = X - M$

  • Therefore, $CA = NFI$ and the Financial Account must offset the Current Account to balance the BOP.

• Implications:

  • If income exceeds expenditures, savings exceed investment, creating a capital surplus; surplus capital is invested abroad (net foreign investment positive).

  • If saving > investment, net exports are positive and the Current Account runs a surplus; this implies a Financial Account deficit (capital outflow financed by foreign investments).

  • Conversely, if savings < investment, there is a Current Account deficit financed by capital inflows (Financial Account surplus).

• Net Foreign Investment identity (Identity 5.5):

  • $\text{Net Foreign Investment} = X - M$

• When CA is in surplus or deficit, the sign and magnitude of NFI/FA reveal the cross-border capital position and the financing of external imbalances.

Practical Implications of CA and FA Balances

• The two balances must offset each other: CA surplus implies capital outflow (FA deficit); CA deficit implies capital inflow (FA surplus).

• Scenarios:

  • If CA is in surplus, nation is a net exporter of capital.

  • If CA is in deficit, nation is a major capital importer.

• The imbalance in the Current Account can be financed by the Financial Account; policy choices influence the size and direction of these flows.

Coping with the Current Account Deficit — Possible Solutions

• Currency Devaluation: making exports cheaper and imports more expensive to improve CA; however, in a floating-rate regime, exchange rates adjust to trade/ capital flows, and the effect may be lagged or offset.

• Protectionism: tariffs and quotas; tends to raise domestic prices, protect domestic producers, and can reduce import demand, but may not improve the trade balance in the long run; may hurt overall welfare.

• Ending Foreign Ownership of Domestic Assets: restrict foreigners from owning domestic assets; could eliminate the CA deficit but results in higher domestic interest rates and slower growth.

• Increase Saving & Reduce Government Budget Deficit: raise private saving and reduce government deficits; policies include tax-advantaged savings, switching to consumption taxes, and reducing fiscal deficits.

• The effectiveness of these policies depends on the specific country context and the state of the external sector.

Currency Devaluation — Mechanisms and Limitations

• Concept: devaluing the currency makes exports cheaper and imports more expensive, which should improve the current account.

• Why it may be unlikely to work in practice:

  • In a floating exchange rate system, currency supply/demand from trade and capital flows adjust; the expected improvement may be delayed or negated.

• J-Curve Theory:

  • As a currency depreciates, the trade balance may initially worsen before it improves over time due to price and volume effects; purchases of imports remain sticky in the short run leading to a temporary deficit widening before improvement.

• Example explanation: U.S. trade balance shows delayed improvement after a dollar depreciation due to lagged effects and changes in import/export volumes.

J-Curve—Explanation and Implications

• Lagged effects: time required for price and quantity adjustments to affect trade balances following a currency move.

• J-Curve shape: initial deterioration followed by improvement in the trade balance after depreciation.

• Two factors contributing to J-Curve outcomes:

  • Relative price effect: prices of imports/exports respond differently to currency changes.

  • Volume effect: quantity demanded for imports/exports adjusts over time as prices evolve.

Protectionism — Tariffs, Quotas, and Welfare Effects

• Tariffs increase import prices, encouraging domestic substitution and domestic producers; protective but may reduce purchasing power and living standards.

• Quotas limit supply of imports, raise domestic prices, and promote domestic substitutes.

• Effects on trade balance are not straightforward; overall welfare effects are ambiguous and may shift but not necessarily improve the trade balance in the short or long run.

• Example: restrictions on steel imports can raise the domestic price level and affect other sectors through related price changes.

Ending Foreign Ownership of Domestic Assets — Trade-offs

• Policy: prohibit foreigners from owning domestic assets.

• Potential outcome: foreign capital inflows/outflows collapse; CA deficit could be eliminated if foreigners reduce demand for domestic assets.

• Major downside: higher domestic interest rates, reduced investment, and slower growth due to loss of foreign capital and higher financing costs.

Increasing Saving & Reducing Government Budget Deficit — Policy Measures

• Increase saving through policy changes:

  • Promote tax-advantaged saving vehicles.

  • Switch from income tax to consumption tax to encourage saving.

• Reduce government budget deficit: reduce government spending or increase taxes to lower public deficits.

• Resulting identities:

  • $\text{Savings} - \text{Investment} = X - M$

  • $\text{Govt. Budget Deficit} = \text{G} - \text{T}$ (government spending minus taxes)

• Goal: raise national saving relative to investment to improve the Current Account position.

Key Takeaways — Connections and Intuition

• The Balance of Payments must balance: current account, capital account, and financial account balance with reserve changes sum to zero (the BOP is a bookkeeping identity).

• The Current Account reflects a nation’s net exports of goods and services plus net income and net unilateral transfers; its balance is closely tied to savings and investment behavior.

• The Financial Account captures cross-border ownership of financial assets and capital flows; it must offset the current account (in the sense that a CA deficit is financed by FA inflows, and vice versa).

• Identities link the macro aggregates: Savings, Investment, Exports, and Imports determine CA and FA positions; government deficits interact with private saving and investment to affect the CA.

• Policy responses to CA imbalances must consider the broader consequences (growth, employment, welfare) and the lagged effects of exchange rate changes, capital mobility, and price adjustments.

Useful Formulas (for quick reference)

• Balance of Payments: $\text{BOP} = (X - M) + (CI - CO) + (FI - FO) + FXB$

• Current Account components: $CA = (X - M) + (Income) + (Unilateral\ Transfers) + (Balance\ on\ Services)$

• Current Account balance vs. Financial Account balance linkage (identity):

  • $CA = X - M$

  • $NFI = X - M$

  • Hence $CA = NFI$ and the Financial Account must offset this movement to balance the BOP.

• National Income and Expenditure identities:

  • $NI = C + S$

  • $NE = C + I$

  • $NI - NE = S - I$

  • $NI = (domestic\ goods/services) + X$

  • $NE = (domestic\ goods/services) + M$

  • Therefore $NI - NE = X - M$

• Key policy relationships:

  • If savings > investment, capital surplus, net foreign investment positive, CA surplus, FA deficit.

  • If savings < investment, capital shortage, net foreign investment negative, CA deficit, FA surplus.
