Abstract
Properties of the 3-month Treasury bill rate changed on and around the listing date of the IRX options for which the Treasury bill rate is the underlying. The level of return declined, the volatility declined and dummy variables for the day of listing and the 2 days after are negative and significant in an econometric model. The changes are consistent with the option-listing effect observed with the listing of options on stocks and American Depositary Receipts (ADRs).
