Trade balance
Hypothetical goods exports are 120 billion and imports 100 billion in the same currency and period. The balance is +20 billion. This does not imply an identical purchase of domestic currency: invoicing, hedging and use of receipts can differ.
Statistical coverage
Trade balance often refers to goods; check the release's terminology. Goods-and-services balance is broader, and the current account also includes income and transfers. Do not compare these without matching coverage.
Prices, volumes and invoicing
Commodity-price changes can alter the balance without volume growth. An exporter may receive USD and retain it or have sold it forward. The buyer need not always purchase the exporter's currency directly.
The exchange-rate relationship
Financial flows, expectations and hedging can outweigh trade. Depreciation may initially increase import costs before volumes adjust. A surplus guarantees neither appreciation nor precise timing.
FAQ
Does a trade surplus imply a current-account surplus?
Not always. Services, income and transfers can change the overall balance.
Does every deficit automatically weaken a currency?
No. Financing, capital flows and expectations also matter.
