What causes equilibrium interest rates to rise?

Equilibrium interest rates rise primarily due to an increase in demand for credit, which can occur when businesses and consumers seek to borrow more for investment and spending. Additionally, a decrease in the supply of available funds, such as when banks tighten lending standards or when savings decline, can also push rates higher. Inflation expectations may further contribute to rising rates, as lenders demand higher returns to compensate for the anticipated decrease in purchasing power. Lastly, shifts in monetary policy, such as central banks raising benchmark rates, directly influence equilibrium interest rates.
