The pressure came as oil prices retreated on Wednesday following an unexpectedly large build-up in United States crude inventories. However, supply disruptions in the Middle East continued to linger across Asian markets, keeping global energy markets unsettled.

During the session, automobile assemblers, cement companies, commercial banks, oil and gas exploration firms and oil marketing companies came under selling pressure, weighing on the broader index.

The KSE-100 had closed at 169,392.32 in the previous session.
