The Optimum Quantity of Central Bank Reserves

Staff working paper 2025-15 Jonathan Witmer
This paper analyzes the optimal quantity of central bank reserves in an economy where reserves and other financial assets provide liquidity benefits. Using a static model, I derive a constrained Friedman rule that characterizes the socially optimal level of reserves, demonstrating that this quantity is neither necessarily large nor small but depends on the marginal benefits of reserves relative to alternative safe assets.

Estimating Canada’s Effective Lower Bound

Recently, the Bank of Canada has estimated the effective lower bound (ELB) on its policy interest rate to be about -50 basis points. This article outlines the analysis that underpins that estimate by quantifying the costs of storing and using cash in Canada. It also explores how some international markets have adapted to negative interest rates, issues surrounding their implementation, as well as their transmission to other interest rates in the economy. Finally, it discusses theoretical ideas on how the ELB could be reduced further.
