Balance of Payments: Keeping Score Internationally

Every transaction between a UK resident and the rest of the world is recorded in the Balance of Payments. It is like a giant bank statement for the whole country — money flowing in for exports, money flowing out for imports, loans given and received, investments made abroad and attracted from abroad.

💳 The Personal Bank Statement Analogy: Your bank statement records every pound coming in (salary, gifts) and going out (shopping, bills). A deficit means you're spending more than you earn — and covering it by borrowing or dipping into savings. The UK's current account deficit works the same way: we buy more from the world than we sell to it, and must finance the gap by borrowing from abroad or selling UK assets to foreign investors.

📦 Current Account

Trade in goods (visible) + trade in services (invisible) + income flows + current transfers. UK typically runs a deficit here.

💼 Capital Account

Capital transfers (debt forgiveness, migrant transfers) and non-financial assets. Relatively small.

🏦 Financial Account

FDI, portfolio investment (shares/bonds), reserve changes. A current account deficit is financed here — foreigners invest in UK assets.

⚖️ Overall Balance

Always balances to zero in theory (current + capital + financial + errors/omissions = 0). Any deficit in one section is a surplus in another.

Marshall-Lerner Condition:
Depreciation only IMPROVES the current account if:
|PED exports| + |PED imports| > 1
(i.e., if demand for exports and imports is sufficiently price elastic)

💡 How to read economic diagrams: Always label axes (Price on Y-axis, Quantity on X-axis for most diagrams). Shifts represent changes in non-price factors; movements along a curve represent price changes. Equilibrium is where curves intersect.
