Suppose the nominal interest rate in the U$.$S$.$ is $4\%$ per year, the nominal interest rate in Brazil is $12\%$ per year, and today's spot rate is $S(\frac{S}{B}RL)=0\mathrm{.}21.$ If the International Fisher Effect holds, what are the expected spot rates $S(\frac{\text{\$}}{B}RL)$ in three months, $6$ months, and $1$ year?
