What you will learn

  • Map policy rate changes to lending benchmarks
  • Interpret yield curve movements
  • Assess quantitative easing and tightening footprints

Start with a real question

Why does a central-bank rate increase affect mortgages, investment, jobs, and inflation?

Core concept

Policy rates influence market borrowing costs, asset prices, exchange rates, expectations, spending, and ultimately inflation with variable lags.

Cause→Economic mechanism→Observed outcome

Data connection

Real rates chart the stance of monetary policy.

Real interest rate (%) · FR.INR.RINR

Worked example

Step through it

A 0.5-point hike raises variable borrowing costs quickly, while fixed mortgages reset later. Investment and consumption soften before lower demand feeds into hiring and price pressure.

Mini practice

  1. Trace one channel from a rate hike to inflation.
  2. Why are policy lags uncertain?
  3. How might a recession change the effect of a hike?

Common mistake

Assuming the policy rate changes every household's loan rate immediately and equally.
