The accounts in the balance of payments

The balance of payments records transactions between residents of one economy and the rest of the world over a period. Receipts are credits and payments are debits.

Account Main recorded flows
current account trade in goods and services; primary income such as profit, interest and compensation; secondary income such as transfers
capital account capital transfers and transactions in non-produced, non-financial assets
financial account foreign direct investment, portfolio investment, other financial flows and changes in reserve assets

A current-account deficit must be matched by net financing, reserve changes and the other accounting entries, allowing for errors and omissions. For example, lower inward FDI or portfolio investment weakens the financial-account position, not the current account directly.

The balance of trade in goods and services is only part of the current account. Government borrowing is not automatically a balance-of-payments entry unless it involves a non-resident transaction.

Why current-account deficits and surpluses arise

A current-account deficit means total current-account debits exceed credits; a surplus means credits exceed debits. The balance reflects trade, income and transfers, not exports and imports alone.

Change Route towards deficit Reverse route towards surplus
relative productivity/cost low productivity raises unit cost and export price strong productivity lowers unit cost and supports exports
relative inflation/exchange rate high inflation or an overvalued currency weakens price competitiveness low relative inflation or depreciation can strengthen it
domestic and foreign income rapid domestic growth raises import demand strong foreign growth raises export demand
structure and non-price quality weak skills, capacity, quality or infrastructure limit exports specialisation, reliability and innovation support exports
commodity prices a fall in a main export price cuts receipts a rise in a main export price raises receipts
income and transfers profit, interest or transfer outflows exceed inflows net income or transfer inflows strengthen the account

Diagnose the component, duration and size relative to GDP. A one-year deficit may reflect investment-related imports, whereas a persistent deficit linked to weak productivity suggests a deeper competitiveness problem.

A deficit is not caused by one factor in every country, and a surplus is not proof of higher living standards. The current account is a flow measured over time.

Correcting a current-account imbalance

Measure for a deficit Transmission route Main cost or condition
deflationary fiscal or monetary policy lower income and spending reduce import demand weaker growth and higher unemployment; higher interest may appreciate the currency
currency depreciation/devaluation exports become cheaper abroad and imports dearer domestically improvement depends on elasticities and may follow a J-curve
education, infrastructure and investment support productivity, quality and capacity improve export competitiveness long time lags, fiscal cost and uncertain response
diversification and innovation wider, higher-value exports reduce dependence requires skills, finance and market access
tariffs, quotas or import substitution import spending is restrained retaliation, higher input prices and distorted comparative advantage

To reduce an excessive surplus, the reverse adjustment may include currency appreciation, stronger domestic demand or investment, higher imports and policies that raise household consumption. Adjustment can be shared between surplus and deficit economies.

Use a policy mix matched to the cause: demand restraint addresses excessive import demand, while supply-side policy addresses weak long-run competitiveness.

Reducing a deficit is not automatically welfare-improving. A smaller deficit achieved through recession differs from one achieved through productivity-led export growth.

Why global trade imbalances matter

Global trade imbalances are persistent current-account surpluses in some economies mirrored by deficits elsewhere. They link trade flows to international borrowing, lending and asset ownership.

Persistent deficit risk Persistent surplus risk or counterpart
reliance on continued foreign financing and confidence reliance on external demand and accumulation of foreign assets
growing foreign liabilities and income outflows exposure to debtor default, currency loss or weak overseas demand
pressure for depreciation, higher interest rates or policy restraint pressure for appreciation or international demands to expand domestic demand
weak competitiveness and structural unemployment when the cause is supply-side subdued domestic consumption or investment when saving is persistently high

Significance depends on duration, the balance as a share of GDP, reserve holdings, currency denomination, what financing funds and whether adjustment is orderly. Capital-goods imports that raise future capacity can make a deficit more sustainable than consumption financed by unstable short-term inflows.

Every deficit needs a counterpart flow, but it is not automatically a crisis. Financing quality, productive use and investor confidence matter more than the cash total alone.

Fixed, managed and floating exchange rates

An exchange rate is the price of one currency in terms of another. Regimes differ by how that price is determined and how strongly authorities commit to influence it.

Regime How the rate is determined Policy requirement/trade-off
floating market demand and supply determine the rate automatic movement but possible volatility
managed float market sets the rate, with occasional official intervention discretion can smooth or steer movements but uses policy tools/reserves
fixed authority commits to a stated rate or narrow band against another currency/basket intervention, reserves and compatible monetary policy are needed to defend it

A floating rate can still be influenced by interest rates or intervention; it is managed only when authorities deliberately steer it. A fixed rate may be adjusted officially but is not continuously market-clearing.

Fixed does not mean immovable forever, and floating does not mean free of government influence. Classify the mechanism, not the temporary stability of the observed rate.

How authorities intervene in currency markets

Tool To support/raise the currency To reduce the currency
foreign-currency transactions buy domestic currency and sell foreign reserves, raising domestic demand sell domestic currency and buy foreign assets, raising domestic supply
interest rate raise the relative return on domestic assets, tending to attract capital lower the relative return, tending to reduce capital inflow
quantitative easing reduce or reverse asset purchases, limiting money/liquidity expansion buy assets and expand liquidity, tending to lower yields and currency demand

Intervention can be limited by finite reserves, speculative pressure and conflict with inflation, growth, employment or financial-stability goals. Interest-rate effects depend on relative rates, risk and expectations; QE does not mechanically set an exchange rate.

To support a falling peso against the dollar, a central bank can sell dollars and buy pesos. The transaction simultaneously increases demand for pesos and supplies dollars.

Buying the foreign currency while selling the domestic currency lowers, rather than supports, the domestic currency. State both sides of the transaction.

What moves a floating exchange rate

A floating currency appreciates when demand rises relative to supply and depreciates when demand falls or supply rises. Each factor works through trade or capital flows and expectations.

Specified factor Typical route to appreciation Reverse route to depreciation
relative interest rates higher risk-adjusted return attracts financial inflows lower return encourages outflow
relative inflation (PPP) lower inflation preserves purchasing power and competitiveness higher inflation weakens purchasing power and export demand
current account stronger export/income receipts raise currency demand persistent deficit raises supply relative to demand
strength of economy confidence, profits and investment attract capital recession, debt/default fear or instability deters it
capital flight reversal or repatriation restores demand residents/investors sell domestic assets and currency
expectations/speculation expected rise causes buying now expected fall causes selling now
global/commodity factors higher key export prices raise receipts for an exporter lower commodity prices weaken a commodity exporter's currency

The effect is relative and conditional: a higher interest rate may signal risk, while strong growth can raise imports. Short-run financial flows can outweigh current-account flows.

Revaluation versus appreciation

Both revaluation and appreciation mean that a currency buys more foreign currency. The difference is the exchange-rate regime and the cause of the rise.

Term Regime Cause
appreciation floating or managed-floating rate market demand rises relative to supply
revaluation fixed-rate system the authority officially raises the currency's fixed value

If a floating rate moves from 1 domestic unit buying 0.80to0.80 to0.90, it appreciates. If a government changes a fixed parity from 0.80to0.80 to0.90, it revalues the currency.

A rise in a quoted number means appreciation only when the quote states foreign currency per unit of domestic currency. Always read the quotation direction before naming the movement.

Devaluation versus depreciation

Both devaluation and depreciation mean that a currency buys less foreign currency. The difference is whether the fall is an official parity decision or a market movement.

Term Regime Cause
depreciation floating or managed-floating rate market supply rises relative to demand
devaluation fixed-rate system the authority officially lowers the currency's fixed value

If a floating currency falls from 1.20to1.20 to1.05 per domestic unit, it depreciates. If an authority lowers a fixed parity by the same amount, it devalues the currency.

A government can influence a floating rate, but a market fall is still depreciation. Devaluation refers specifically to an official reduction under a fixed regime.

How an exchange-rate change affects the economy

A depreciation makes exports cheaper to foreign buyers and imports dearer domestically; appreciation reverses these price effects. Quantities, contracts, capacity and expectations determine the final outcome.

Area after depreciation Likely channel Key condition
current account export volume rises and import volume falls Marshall-Lerner: the sum of export and import demand elasticities exceeds 1
J-curve import bill rises before quantities adjust, then the balance may improve contracts and low short-run elasticities delay adjustment
capital/financial accounts and FDI domestic assets become cheaper, but returns/confidence and expected further changes matter inflows are not guaranteed; profit repatriation affects primary income
growth and employment stronger net exports raise AD, output and derived demand for labour spare capacity, multiplier and supply response matter
inflation dearer imports cause cost-push pressure; higher AD can add demand-pull pressure pass-through, margins and productivity affect scale

Appreciation tends to weaken net exports, growth and employment but lowers import costs and inflationary pressure. It can also make foreign assets cheaper for domestic investors.

A depreciation does not automatically improve the current account or attract FDI. The Marshall-Lerner condition, J-curve timing, confidence and non-price competitiveness control the result.

Competitive depreciation and devaluation

A competitive depreciation or devaluation is an attempt to lower a currency to gain export price competitiveness and redirect demand towards domestic output, sometimes described as a beggar-thy-neighbour policy.

Intended domestic gain Wider consequence or limit
cheaper exports and dearer imports raise net exports partners lose demand and may retaliate with intervention or trade barriers
higher AD supports growth and employment imported inflation and dearer inputs squeeze real income and supply
current account may improve Marshall-Lerner may fail and the account may first worsen along a J-curve
lower rate attracts some cost-sensitive FDI instability and fear of further falls can deter capital

If many countries try to depreciate together, they cannot all improve relative competitiveness. Repeated intervention can create currency conflict, volatile capital flows, protectionism and weaker international cooperation.

A lower exchange rate is a relative price, not a source of global aggregate demand by itself. One country's trade gain can be another's loss.

Measuring international competitiveness

International competitiveness is an economy's ability to sell goods and services in world markets on price and non-price terms while sustaining productive performance. The syllabus measures focus on relative, not absolute, performance.

Measure Interpretation
relative productivity growth faster output per worker/hour growth can lower resource cost per unit
relative unit labour cost labour cost per unit of output compared with trading partners; lower growth strengthens cost competitiveness
relative export prices export-price movement compared with competitors; lower relative prices strengthen price competitiveness, other things equal

$Unit\ labour\ cost=\dfrac{labour\ cost}{units\ of\ output}\quad\text{(approximately wage\ cost/productivity)}$

If wages rise 3% while productivity rises 5%, unit labour cost tends to fall. If productivity falls with unchanged wages, unit labour cost tends to rise and firms may raise export prices.

A lower export price is not complete evidence of competitiveness: quality, reliability, design and service can support demand even at a higher price.

What determines international competitiveness

Factor Competitiveness channel
productivity and human capital skills, organisation and technology raise output/quality per input and lower unit cost
exchange rate depreciation lowers foreign-currency export prices but raises imported-input costs
wage and non-wage costs pay, payroll charges and employment costs affect unit cost relative to productivity
regulation well-designed rules can build quality/trust; burdensome compliance can raise cost and delay entry
infrastructure reliable transport, energy and digital networks reduce time, loss and logistics cost
non-price factors quality, design, innovation, reliability, branding and after-sales service sustain demand

The factors interact: high wages can coexist with strong competitiveness when productivity and non-price quality are high, while depreciation cannot repair weak infrastructure or unreliable products.

Assess goods and services separately and compare with trading partners. A domestic improvement is not a relative gain if competitors improve faster.

Low wages are not the same as low unit labour costs. Divide labour cost by output, and include quality and productivity before judging competitiveness.

Policies to raise international competitiveness

Specified measure Intended route Main trade-off
education and training stronger human capital raises productivity, innovation and quality fiscal cost, time lag and risk skills do not match jobs
investment incentives tax relief, finance or grants raise capital, technology and capacity deadweight cost and dependence on business confidence
privatisation and deregulation competition and incentives can reduce inefficiency and entry cost market power, service quality or external costs may worsen
reduce the exchange rate foreign-currency export prices fall imported-input inflation and retaliation; effect may be temporary
trade liberalisation import competition and wider markets encourage efficiency and scale adjustment losses and exposure to external shocks

Infrastructure, health, innovation and reduced administrative delay can reinforce the specified policies by improving productive reliability and non-price performance.

Choose measures to match the diagnosed weakness and compare short-run price effects with long-run productivity and quality. A coordinated package may work better than an isolated subsidy or exchange-rate move.

Privatisation, deregulation or depreciation does not guarantee lower unit cost. Competition, institutions, pass-through, confidence and implementation determine the outcome.

Why international competitiveness matters

An internationally competitive economy can sustain demand for its goods and services against foreign alternatives. Significance runs through exports, investment, productivity and employment, not ranking tables alone.

Competitive economy: possible advantage Uncompetitive economy: possible problem
stronger exports and current-account position weak exports and persistent current-account deficit
higher AD, growth and employment slower growth and structural unemployment in exposed sectors
scale, innovation and investment from access to wider markets low investment, lost market share and slower productivity growth
attractive price/quality offer can draw FDI FDI may locate in more productive, reliable or lower-cost economies
efficiency supports real wages and tax capacity depreciation or wage restraint may be used defensively, lowering real purchasing power

Benefits depend on productive capacity, income distribution, import content and environmental costs. Strong domestic demand, services or capital inflows can make a temporary trade deficit manageable, while export success based only on low wages may not raise living standards.

Competitiveness is relative and multidimensional. A lower currency or lower wage can improve price competitiveness while worsening import costs, inflation or worker welfare.
