This paper considers a portfolio model of exchange rate determination and focuses on endogenous sources of exchange rate volatility. We show that, in addition to volatility transmitted by conditionally heteroskedastic interest rates, the larger the serial correlation in interest rates the stronger the effect of interest rate differentials on exchange rate volatility. These features are supported by the data. We also look at the volume-volatility relationship implied by the model.
