Policy Rate
Definition
The benchmark interest rate set by a central bank that determines the cost at which commercial banks can borrow funds overnight, serving as the primary instrument of monetary policy.
Simple Explanation
The policy rate is the SBP's main lever for controlling the economy. When the SBP raises the policy rate, it becomes more expensive for banks to borrow — so they charge more for loans to businesses and consumers. This slows spending, which brings inflation down. When the SBP cuts the rate, borrowing becomes cheaper, stimulating the economy.
In Pakistan
The SBP's Monetary Policy Committee (MPC) reviews the policy rate every 8 weeks. Pakistan's policy rate cycle from 2022–2024 was one of the most dramatic in SBP history: from 7% in early 2022 to a peak of 22% in June 2023 (to combat 38% CPI inflation), then cut back to the low teens by end-2024 as inflation fell. The SBP operates a corridor system: the policy rate sits between the SBP's overnight lending rate (ceiling) and overnight deposit rate (floor).
Example
If the SBP sets the policy rate at 15%, a commercial bank might set its lending rate at 17–18% (policy rate + spread for credit risk and profit). A business borrowing at 18% for a year on PKR 1 million pays PKR 180,000 in interest — money that could otherwise have been invested.
Frequently Asked Questions
What is the 'real' policy rate?
The real policy rate = nominal policy rate − inflation. It shows what the policy rate actually means in purchasing power terms. A 22% nominal rate with 38% inflation gives a real rate of −16% — meaning monetary policy was still accommodative despite the high nominal rate. Central banks try to keep the real rate positive to genuinely tighten financial conditions.
