Interest rates and inflation
Higher interest rates raise borrowing costs and weaken demand; inflation raises costs and creates uncertainty.
Interest rates are the cost of borrowing money (and the reward for saving).
When interest rates rise:
- Loans and overdrafts cost more → higher costs for businesses with borrowing (especially highly-geared firms).
- Consumer demand falls, particularly for goods bought on credit (cars, houses, big appliances) — repayments rise and saving becomes more attractive.
- Investment falls — firms delay borrowing to expand, as projects must clear a higher return.
When rates fall, the reverse: cheaper borrowing, stronger demand, more investment.
Inflation is a sustained rise in the general price level.
- ✅/❌ It raises a firm's costs (materials, wages as workers demand pay rises) → squeezed margins or higher prices.
- ❌ It creates uncertainty, making planning and pricing harder, and can make exports less competitive if a country's inflation is higher than rivals'.
- ✅ It erodes the real value of debt — a fixed loan is easier to repay in inflated money — and firms may raise prices ahead of costs.
The link to interest rates: central banks often raise interest rates to control inflation — so the two frequently move together, both dampening demand.
- Interest rates = the cost of borrowing.
- Higher rates → costlier loans, weaker demand (esp. credit goods), less investment.
- Inflation = sustained rise in the general price level.
- Inflation raises costs and uncertainty but erodes the real value of debt.
- Central banks often raise rates to control inflation — the two move together.
