Understanding Exchange Rate Regimes

Understanding Exchange Rate Regimes

Almost every exchange rate regime has its flaws, virtues, and particularities. Since exchange rates in different currencies fluctuate due to the influence of market forces, some nations peg their currencies on other currencies. Others, still, have market-determined floating rate regimes. That said, exchange rate arrangements are mainly used by developing economies.

Floating Exchange Rate

Most medium-sized nations have successfully managed to maintain floating exchange rate regimes over long periods of time. Floating exchange rate regimes use the market forces to dictate their currencies’ exchange rates.

Pegged Currencies

The monetary systems of some nations, for example, China, use pegged exchange rate regimes. This means exchange rates are fixed to other currencies for a certain period of time. In the case of China, the yuan is pegged on the US dollar. The cornerstone of China’s economic policy is managing the yuan exchange rate to benefit its exports.


Dollarization refers to a case in which a foreign currency is used as legal tender in addition to or instead of the domestic currency. This is mostly the case for small (and sometimes unstable) countries such as Ecuador, El Salvador, the British Virgin Islands, and Zimbabwe, which use the U.S. dollar instead of their own currency. Other examples include Kosovo and Montenegro, which use the Euro without being part of the Eurozone.


If the fluctuation of a country’s currency is exactly in tune with the US dollar because of central bank interventions, it would most likely be an example of:

A. dollarisation.

B. a pegged currency.

C. a floating exchange rate regime.


The correct answer is B.

If a country has it’s own currency and its fluctuation is in tune with the US dollar, then it’s an example of a currency that is pegged on the US dollar. China is a good case in point.

A is incorrect. Dollarization refers to a case in which a foreign currency is used as legal tender instead of the domestic currency.

 C is incorrect. Floating exchange rate regimes simply use the forces of the market to dictate their currencies’ exchange rates.

    Excelente para el FRM 2 Escribo esta revisión en español para los hispanohablantes, soy de Bolivia, y utilicé AnalystPrep para dudas y consultas sobre mi preparación para el FRM nivel 2 (lo tomé una sola vez y aprobé muy bien), siempre tuve un soporte claro, directo y rápido, el material sale rápido cuando hay cambios en el temario de GARP, y los ejercicios y exámenes son muy útiles para practicar.
    So helpful. I have been using the videos to prepare for the CFA Level II exam. The videos signpost the reading contents, explain the concepts and provide additional context for specific concepts. The fun light-hearted analogies are also a welcome break to some very dry content. I usually watch the videos before going into more in-depth reading and they are a good way to avoid being overwhelmed by the sheer volume of content when you look at the readings.

    A great curriculum provider. James sir explains the concept so well that rather than memorising it, you tend to intuitively understand and absorb them. Thank you ! Grateful I saw this at the right time for my CFA prep.

    Professor James' videos are excellent for understanding the underlying theories behind financial engineering / financial analysis. The AnalystPrep videos were better than any of the others that I searched through on YouTube for providing a clear explanation of some concepts, such as Portfolio theory, CAPM, and Arbitrage Pricing theory. Watching these cleared up many of the unclarities I had in my head. Highly recommended.
