THE PRICE OF OPTIONS ILLIQUIDITY

Abstract

The purpose of this paper is to examine the effect of illiquidity on the value of currency options. We use a unique data set which allows us to explore this issue in special circumstances where options are issued by a central bank and are not traded prior to maturity. The value of these options is compared to similar options traded on the exchange. We find that the non-tradable options are priced about 21 percent less than the exchange traded options. This gap cannot be arbitraged away due to transactions costs and the risk that the exchange rate will change during the bidding process.
