Exchange Rates and Currency Regimes

This section now focuses on the economics of exchange rates and currency regimes instead of acting as a flat catch-all for every FX-related term.

Use it for exchange-rate measurement, real and nominal rates, currency regimes, pegs and floats, appreciation and devaluation, monetary standards, currency unions, convertibility, and capital controls.

Trading conventions, currency pairs, FX derivatives, hedging tools, benchmark rates, Eurocurrency markets, and low-value individual currency stubs have been moved, merged, or removed so this branch stays policy and economics focused.
