Why Creating More Money Can Weaken a Currency
Printing banknotes is not the same as expanding the money supply. Currency weakness becomes more likely when money and spending grow persistently faster than an economy’s capacity.
Most money is not physical cash
The phrase “printing money” is often misleading. In modern economies, most money is held as commercial-bank deposits, and banks create deposits when they make loans. Central banks issue physical currency and influence monetary and credit conditions through policy rates, liquidity operations and other tools.
Printing replacement notes or meeting normal demand for cash does not by itself create inflation. The economic question is whether total money, credit and spending are expanding relative to the supply of goods and services.
Too much demand can push prices higher
When households, firms and government can spend more but the economy cannot increase production at the same pace, competition for available goods and services can lift the general price level. The IMF notes that long episodes of high inflation are often associated with money supply growing too large relative to the economy.
The relationship is not mechanical in the short run. People may hold additional balances, banks may reduce lending, or unused production capacity may respond. Supply disruptions, taxes, wages, expectations and fiscal policy also affect inflation.
How inflation can pressure the exchange rate
If domestic prices rise persistently faster than prices abroad, the currency’s purchasing power falls at home and its international competitiveness can weaken. Residents and investors may seek foreign currency to protect value, increasing demand for it and putting pressure on the domestic exchange rate.
Lower confidence, negative real interest rates and expectations of further inflation can reinforce the move. But exchange rates also respond to exports, imports, remittances, capital flows, reserves, global interest rates and political risk.
Money creation can be useful when disciplined
Central banks sometimes supply liquidity to keep payment systems working or prevent a severe fall in demand. Bank credit can finance productive investment that expands future capacity. The effect depends on scale, timing, economic conditions and whether policy remains credible.
The dangerous pattern is persistent monetary financing or credit expansion without matching output and confidence. That can turn a temporary price increase into continuing inflation and currency substitution.
Ethiopia’s policy framework
NBE introduced an interest-rate-based monetary policy framework in 2024, supported by open-market operations and facilities for managing banking-system liquidity. Its stated primary objective is low and stable inflation.
