Exposure is a measure of the sensitivity of the value of a financial item (asset, liability or cash flow) to changes in the relevant risk factor while risk is a measure of variability of the value of the item attributable to the risk factor. Let us understand this distinction clearly. April 1993 to about July 1995 the exchange rate between rupee and US dollar was almost rock steady. Consider a firm whose business involved both exports to and imports from the US. During this period the firm would have readily agreed that its operating cash flows were very sensitive to the rupee-dollar exchange rate, i.e.; it had significant exposure to this exchange rate; at the same time it would have said that it didn’t perceive significant risk on this account because given the stability of the rupee-dollar fluctuations would have been perceived to be minimal. Thus, the magnitude of the risk is determined by the magnitude of the exposure and the degree of variability in the relevant risk factor.
