Explanation / Answer
using interest rate parity the formula for forward rate = spot rate *(1+interest rate in foreign currency)^n / (1 + interest rate in home)^n
here,
US is home
Singapore is abroad.
n is number of years, since nothing is given we assume it to be 1 year.
now,
forward rate = 1.36 * (1.06)^1 / (1.03)^1
=>SGD 1.40 /USD.
the forward rate to prevent interest rate arbitrage = SGD1.40 per USD.
