Interbank Rate

The interbank rate is the short-term interest rate at which banks lend funds to one another.

It is a core money-market rate because it reflects liquidity conditions inside the banking system and often influences broader short-term borrowing costs.

Why It Matters

Interbank rates help transmit monetary policy into the financial system.

When liquidity tightens or credit concerns rise, these rates can move, and those moves often affect other short-term funding costs across markets.

Worked Example

If banks become more cautious about lending to one another, the interbank rate may rise even before households or businesses see the full effect in their own borrowing conditions.

That makes the interbank market a useful early signal of funding stress.

Scenario Question

A borrower says, “Interbank rates only matter to large banks, not to the rest of the economy.”

Answer: No. These rates often influence broader money-market pricing and the transmission of policy into credit conditions.
