The KSE-100 shed 4,817 points over the week of 7–11 September, closing at 170,512 - a loss of 2.75% that pushed the month-to-date return to –3.65% and the calendar-year figure to –2.04%. The week's closing range of 4,771 points, between a Thursday trough of 168,865 and the prior Friday's close of 175,329, made it the sharpest weekly drawdown since mid-July.
The damage accumulated steadily across four sessions before reversing on the fifth. Monday opened the week with broad selling in banks, oil and gas, and cement as the market priced in rising geopolitical tension. Tuesday and Wednesday drifted lower as Iran's rhetoric hardened and Brent crude climbed toward $100 - each session giving back ground without a single decisive catalyst. Thursday crystallised the fear: Iran launched its largest attacks on Gulf shipping since the conflict began, and the index fell 3,079 points in a single session, the worst day of the year to that point, with the index touching 168,865. Then Friday turned. Reports emerged of Gulf–Iran diplomatic contacts, and bargain hunters moved in across beaten-down names, adding 1,647 points to close the week at 170,512 - a recovery that erased about a quarter of the four-day loss.
The Friday rebound was the silver lining, but context matters: 1,647 points returned against 6,464 lost. The recovery nonetheless confirmed that 168,000–169,000 is a zone where buyers step in, and the market's ability to close the week above 170,000 preserved the broader technical structure.
At 170,512 the KSE-100 sits roughly 8% below its July record, calendar 2026 is now marginally negative, and the dominant variable remains the same one it has been all quarter: whether US–Iran diplomacy produces a durable Hormuz framework or continues to oscillate between flare-up and rumour. Until that resolves, every session with an oil headline carries outsized weight — and Thursday this week was the clearest proof of that yet.
KSE-100 closed at 168,155 on 2 October 2026. It was down 1.53% on the week, 3.96% for September and 3.39% for 2026 so far.
