The Brazilian experience in managing interest exchange rate nexus
The interest-exchange rate nexus has been the paramount determinant of the course
of the exchange rate in contemporary Brazil through the operation of carry trade which has
different forms, all related to the interest rate differential. To explain how this works in
Brazil and how the Government has been dealing with it through the exchange rate policy
this paper addresses four main questions: firstly, it discusses some theoretical background
related to the interest-exchange rate nexus; secondly, it makes an attempt to explain why the
interest rate in Brazil is so high, examining briefly the main explanations for it; thirdly it
describes the Brazil’s foreign exchange markets, their size and hierarchy; lastly it explains
the carry trade dynamics in different foreign exchange markets and also the government
policies envisioned to curb it. In the final remarks, some recommendations to improve the
foreign exchange market regulation are made.
