## Abstract

This paper examines the link between exchange rate volatility and economic fundamentals. In the framework of a multivariate volatility model that allows volatility spillover, we develop a new impulse response analysis to estimate and decompose the simultaneous effect of macroeconomic news surprises on the foreign exchange volatility. We show that news announcement effects include two components: a direct and an indirect effect induced by volatility spillover. We show that more than 50 % of the total accumulated news effect on the Pound and the Yen is due to volatility transmission from the two major currencies and mainly from the Euro.
