Exchange rates, expected returns and
risk (PDF)
by Anella

According to theory, higher expected
foreign risk-free returns and foreign currency risk both
increase foreign yields, but have opposing effects on the
value of the foreign currency. This paper exploits that
relationship to jointly identify the unobserved risk-free
return and risk premium components of exchange rates and
expected relative returns. When risk and return are jointly
modelled over a 10-year horizon, UIP cannot be rejected for
any of the eight advanced country USD currency pairs
examined. Innovations in the currency premium are correlated
with 'speculative' positioning in foreign exchange markets,
and for non-reserve currencies, with 'VIX' risk aversion.
Innovations in the risk-free component are correlated with
changes in nominal short-term interest rates. Both expected
returns and risk play important roles in exchange rate
dynamics.
