Why Do Central Banks Raise Interest Rates?
Cooling inflation, and the trade-offs that come with it.
Central banks raise their policy interest rate mainly to slow inflation. Higher rates make borrowing more expensive and saving more attractive, which cools spending and, over time, eases pressure on prices.
The policy rate
A central bank sets a short-term benchmark rate that influences what banks charge each other and, in turn, rates on mortgages, loans and savings.
Changes ripple through the economy gradually, often over many months.
How higher rates slow inflation
When loans cost more, households buy fewer homes and cars, and businesses delay expansion. Less demand means less pressure to raise prices.
Higher rates can also strengthen the currency, making imports cheaper.
The trade-off
Raising rates too much or too fast can slow the economy sharply and increase unemployment.
That’s why central banks move in steps and watch data closely, trying to bring inflation down without causing a recession.
If you have variable-rate debt, rate changes reach your payments quickly. Knowing which of your loans are variable helps you plan.
Frequently asked questions
Do higher rates help savers?
Usually, as banks raise rates on savings accounts and deposits, though often with a lag.
Why not just keep rates low forever?
Very low rates for too long can fuel inflation and asset bubbles.
