Abstract Prior to May 22, 2017, price information displayed on stock exchanges on certain days and on days prior to market-closed holidays required investors in exchange-traded repos to infer repos' actual maturities to place orders at appropriate rates. Repo rates on these days exhibited remarkable seasonalities. On May 22, 2017, the displayed information was modified so investors no longer had to infer actual maturities. Thereafter, the seasonalities disappeared. We ascribe the seasonalities to investors employing an ease-of-processing heuristic that failed to decipher repos’ actual maturities. Disappearance of the mispricing gives greater assurance to investors of securing competitive repo rates.
