A further case for the interest rate system

In-Depth Analysis

Continuing the exploration of arguments supporting the interest rate regime, this article delves into the macroeconomic functions that interest supposedly serves. The advocates claim that interest plays a crucial role in the allocation of scarce capital resources. The capital allocation argument states that interest rates act as a price mechanism for money, directing capital toward its most productive uses. Higher interest rates are supposed to ensure that only projects with returns exceeding the cost of capital receive funding, thereby maximizing economic efficiency. In theory, this creates an optimal distribution of resources across the economy. The savings-investment equilibrium argument posits that interest rates balance the supply of savings with the demand for investment. When savings exceed investment demand, rates fall to encourage more borrowing. When investment demand exceeds savings, rates rise to attract more deposits. This self-correcting mechanism supposedly maintains economic stability. However, the author sets the stage for the Islamic counter-perspective by noting that these theoretical models often fail in practice — during financial crises, interest rate mechanisms can exacerbate problems rather than solve them, as witnessed during the 2007-08 global financial crisis where zero or near-zero interest rates failed to stimulate adequate economic recovery in many economies.
