Interest Rate Theory and Policy

Interest-rate theory, loanable-funds analysis, real and natural rate concepts, liquidity preference, and negative-rate conditions.

Interest rate theory and policy pages explain how rates are determined, how inflation affects borrowing costs, and how central banks and markets think about the price of money.

This section groups loanable-funds analysis, real and natural interest rate concepts, liquidity preference, the Fisher Effect, and high-rate or negative-rate conditions so readers can see the rate-determination story in one place.

It sits beside monetary policy because the pages here describe the theory behind rate setting and transmission, not just the policy tools themselves.
