Interest Rate

The cost of borrowing money, set by the State Bank of Pakistan through the policy rate. Rising interest rates generally weigh on equity valuations by increasing the discount rate applied to future earnings.

01What is Interest Rate?

The definition — and what it means in practice.

An interest rate is the cost of borrowing money, expressed as a percentage. In Pakistan, the State Bank of Pakistan sets a benchmark through the policy rate, which influences the wider rates charged on loans and paid on deposits. For investors, interest rates also affect how future company cash flows are valued: when rates rise, the discount rate used in valuations typically rises too, which can lower the present value of future earnings.

Interest rates matter because they shape both company performance and market pricing. Higher borrowing costs can reduce profits for businesses with significant debt, while also making fixed-income alternatives more competitive versus equities. Lower rates can support valuations by reducing the discount rate and easing financing conditions. Changes in interest rates can therefore influence sector leadership, risk appetite, and the valuation multiples investors are willing to pay for PSX-listed shares.

In plain English

If the interest rate rises, future profits are valued less today, so a share priced at Rs 100 may look expensive at the same earnings outlook.

  • The SBP policy rate is the key benchmark for borrowing costs in Pakistan.
  • Rising rates generally increase discount rates, which can pressure equity valuations.
  • Rates influence company profits through financing costs, especially for leveraged firms.
  • Interest rates affect relative attractiveness of equities versus fixed-income instruments.
  • Market reactions often reflect expectations of future rate changes, not only current levels.

02How interest rate works on the PSX

The Pakistan-specific rules, conventions, and numbers.

On the PSX, investors commonly link interest-rate moves to changes in equity valuation and sentiment. A higher policy rate can translate into higher financing costs for companies and a higher discount rate used by analysts when valuing future earnings. A lower policy rate can have the opposite effect, potentially supporting valuation multiples when other factors are unchanged.

Retail investors also meet interest-rate concepts through Pakistani money-market benchmarks such as KIBOR (Karachi Interbank Offered Rate), which is published each business day under State Bank of Pakistan oversight. While KIBOR is not the policy rate, it is a widely referenced market rate and can be used in loan pricing and valuation work. In practice, PSX commentary may compare equity prospects with returns available on government securities.

If you use regulated leverage in equities, interest rates can matter indirectly through the cost of financing within structures such as the Margin Trading System (MTS) and broker Margin Financing (MFS). Even without borrowing, interest rates can influence how investors interpret dividend yields and earnings prospects, especially when comparing stocks across sectors and risk profiles.

03Common misconceptions

Where investors most often get this wrong.

Myth

If interest rates rise, every PSX stock must fall.

Reality

Rate changes affect companies differently. Debt-heavy firms may feel more pressure, while others may be less sensitive. Prices also depend on earnings, growth, and expectations.

Myth

The SBP policy rate and KIBOR are the same thing.

Reality

The policy rate is set by the State Bank of Pakistan. KIBOR is a market benchmark published under SBP oversight and can move differently from the policy rate.

Myth

Interest rates only matter if you trade on margin.

Reality

Even cash investors are affected because interest rates influence valuation discount rates, business borrowing costs, and the competition between equities and fixed-income returns.
