What is FX Reserves?
FX reserves cover the foreign-currency-denominated component of total international reserves — typically USD, EUR, JPY, GBP and CNY assets held by the central bank. They exclude gold and IMF SDR positions.
Why it matters for FX
FX reserves are the main ammunition for currency-defence operations. Sharp drops can signal active intervention to support the home currency; rebuilds typically follow periods of capital inflow or post-intervention. The data are watched closely after any sharp FX move.
How to read this page
Read month-over-month change rather than the absolute level (which is dominated by valuation effects). Cross-reference with FX moves over the same period to corroborate intervention signals.
What to watch for
- Month-over-month change as intervention proxy
- Valuation vs flow effects
- Reserve-currency composition (COFER for cross-checks)
- Reserve-adequacy ratios
- Coincidence with FX-policy decisions
