150 Bahts – Thailand

In 1978, Thailand's currency situation was characterized by relative stability under a fixed exchange rate regime, managed by the Bank of Thailand. The Thai baht was pegged to a basket of currencies, heavily weighted toward the U.S. dollar, which provided a predictable environment for trade and investment during a period of significant economic transition. This stability was a cornerstone of the government's strategy to promote export-oriented industrialization, a shift from the previous agricultural focus, and it supported the country's integration into the global economy.

This period followed the major devaluation of the baht in 1975, when it was adjusted from approximately 20 baht to 20.50 baht per U.S. dollar. By 1978, the rate had settled around 20.25 baht per dollar, reflecting a managed adjustment. The fixed peg helped control inflation and provided certainty for foreign businesses, which was crucial as Thailand began to attract manufacturing investment, particularly from Japan. However, maintaining the peg required consistent foreign exchange reserves and careful monetary policy to manage the balance of payments.

The stability of 1978, however, existed against a backdrop of regional volatility and internal pressures. The collapse of the Bretton Woods system earlier in the decade and the second oil shock of 1979 would soon test the sustainability of the fixed rate. Furthermore, Thailand's growing current account deficits, driven by imports of capital goods for industrialization, hinted at future pressures that would eventually lead to a series of gradual devaluations in the early 1980s, setting the stage for the more dramatic financial challenges decades later.
