📊 Debate Revived: The True Price of Exchange Rate Stability

A renewed economic policy debate in Sri Lanka compares the merits of a currency board against the current central banking framework, especially regarding reserve accumulation and liquidity. • The Current Framework: Following the 2022 crisis, the Central Bank no longer finances government expenditure. Instead, it buys foreign exchange to rebuild vital reserve buffers post-default. While this creates rupee liquidity, it is backed by foreign assets rather than direct monetary financing of fiscal deficits. • The Core Risk: Critics note that unconstrained reserve accumulation risks expanding domestic liquidity. If credit growth outpaces the economy’s capacity to earn foreign exchange, it triggers pressure on imports, inflation, and the exchange rate. Recent rupee volatility highlights how external shocks (e.g., Middle East tensions affecting fuel and tourism) drive importer demand. • The Currency Board Alternative: Proponents argue a currency board ensures stability by stripping away policy discretion. Under this system: • External shocks automatically drain domestic liquidity as reserves exit. • Interest rates rise and credit conditions tighten automatically to adjust the economy. • Discretionary monetary expansion is prevented from turning balance-of-payments pressures into currency crises. • The Trade-off: While a currency board guarantees greater exchange-rate stability, it shifts the entire burden of external shocks onto the domestic economy. Governments must face hard budget constraints, banks lose liquidity support, and households must absorb higher interest rates and weaker economic activity. The ultimate question is whether Sri Lanka is ready to absorb these strict economic costs for guaranteed stability.
