Why Exchange Rate Interventions Rarely Change the Bigger Picture

After government intervention, the exchange rate declined temporarily,
but soon returned to its previous range.
This pattern often creates confusion and frustration.

Many interpret this as a failure of policy.
However, foreign exchange intervention is not intended
to reverse long-term trends.
Its primary purpose is to reduce excessive volatility,
calm market sentiment, and buy time.

Exchange rates are ultimately shaped by structural factors
such as interest rate differentials, capital flows,
and the global strength of major currencies.
If these underlying conditions remain unchanged,
short-term intervention effects naturally fade.

Understanding this distinction helps set realistic expectations.
Rather than focusing on short-term movements,
it is more useful to ask whether the structure behind the exchange rate
has truly shifted.

In this sense, intervention is not about control,
but about managing instability within unavoidable limits.
