Exchange rates may look like numbers for tourists and traders, but they affect the whole economy. The exchange rate shows how much one currency is worth compared with another. If the tenge weakens against the dollar, imported goods become more expensive in tenge terms. This can affect food, electronics, equipment, fuel, medicine and business inputs.

Currency depreciation can create inflation through import prices. If a country relies heavily on imported goods or imported components, a weaker currency increases costs across the economy. Businesses may raise prices. Households lose purchasing power. Inflation expectations may rise.

But a weaker currency can also help exporters. If local goods become cheaper for foreign buyers, exports may increase. Tourism can become more attractive. The trade-off depends on the structure of the economy: what the country imports, what it exports, and how quickly firms can adjust.

Central banks and governments can respond to currency pressure in several ways.

They can raise interest rates. Higher rates may attract capital and support the currency, but they also make loans more expensive and slow growth.

They can use foreign reserves to defend the currency. This can work temporarily, but reserves are limited. If markets believe reserves are too low, defending the currency can become unsustainable.

They can allow the currency to float. This preserves reserves but may increase inflation.

They can introduce capital controls. This may slow capital flight but can damage investor confidence and create problems for business payments.

Sri Lanka’s 2022 crisis is a powerful example of how currency, debt and imports are connected. The country faced a severe balance-of-payments crisis, foreign currency shortages and difficulties paying for essential imports. A currency crisis is not just a financial chart; it can affect fuel, medicine, food and social stability.

For students, exchange rates are important because they show that finance is interconnected. A government debt decision can affect investor confidence. Investor confidence can affect the currency. The currency can affect import prices. Import prices can affect inflation. Inflation can affect interest rates. Interest rates can affect loans and investment.

In a Phronesia scenario, a currency crisis should force players to make difficult choices:

  • defend the currency or save reserves;
  • raise interest rates or protect growth;
  • prioritize critical imports or debt payments;
  • accept external support or maintain policy independence.

There is no perfect answer. Every decision has a cost.

The key lesson: the exchange rate is not just a market price. It is a signal of trust, competitiveness and financial stability.
