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.
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.
| 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.
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.
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.
| 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.
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.
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 0.80to0.90, it appreciates. If a government changes a fixed parity from 0.80to0.90, 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.
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 1.20to1.05 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.
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.
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.
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.
| 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.
| 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.
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.
