Abstract

To attract time deposits, more than 6,000 banks post their offer rates. I document a large cross-sectional dispersion, negative spreads over Treasuries, and upward rigid adjustments in these rates following federal funds rate increases. Estimates of an oligopoly model reveal a large fraction of high-search-cost and a small declining fraction of low-search-cost investors that can rationalize the observed pricing. Despite high intertemporal elasticity of substitution and technological innovations over the last two decades, the stable large fraction of high-search-cost depositors, mostly elderly households, grants banks significant monopoly power and allows for the sluggish pass-through of increases in the federal funds rate into deposit rates.

Keywords: Deposit rates, Search Costs, Rate rigidity, Rate dispersion, Interest rate pass-through, Coefficient of intertemporal elasticity of substitution, Bank-affiliated money market mutual funds, Limited deposit insurance
