Critics of the current approach argue that relying too heavily on the Overnight Policy Rate ignores the structural limitations of Malaysia's economy. While interest rate hikes are intended to curb inflation, they often disproportionately affect low-to-middle-income households who are already struggling with the rising cost of living. When mortgage and loan repayments increase, these families have less money to spend on essential goods, which can inadvertently dampen domestic demand and slow down the very growth the central bank aims to protect.
There is also a concern that the OPR is a blunt instrument that does not address the root causes of inflation, such as supply chain disruptions or food security issues. Raising rates does little to lower the price of imported goods or fix logistical bottlenecks. Instead, it creates a scenario where businesses are penalized for borrowing to innovate or expand, even when their challenges are not related to excessive demand but rather to high input costs and labor shortages.
Furthermore, the focus on interest rates may distract from the need for more targeted fiscal policies. Critics suggest that the government should take a more active role in addressing productivity and supply-side constraints rather than leaving the burden of economic management entirely to the central bank. Over-tightening monetary policy risks pushing the economy into a period of stagnation, where growth remains sluggish despite inflation being brought under control.
Moving forward, there is a call for a more nuanced approach that considers the social impact of monetary policy. Policymakers should be cautious about the cumulative effect of rate hikes on the average citizen. If the OPR is pushed too high, the resulting economic slowdown could lead to job losses and reduced business activity, proving that there are clear limits to what interest rate manipulation can achieve in a complex, modern economy.
