Nairobi Securities Exchange — Co-op Bank Jumps 5.7% on 2025 Earnings as Banks Drive a Flat Session
Co-operative Bank rose 5.7% to 28.55 KES on March 27, 2026 as a wave of bank earnings hit the NSE. In an otherwise flat market, results from Co-op, I&M, NCBA and DTB overshadowed Kenya Re’s decline and pressure from a weaker shilling at 129.75 per dollar.

The clearest signal from trading on Friday, March 27, 2026 at the Nairobi Securities Exchange did not come from the headline indices, which barely moved, but from bank stocks. Co-operative Bank of Kenya jumped 5.7% to KES 28.55, one of the day’s standout moves, as a flood of full-year 2025 earnings from Co-op Bank, I&M Group, NCBA and Diamond Trust Bank Kenya pulled the sector back to the center of the market.
That move mattered precisely because the broader tape looked frozen. The NASI closed at 706.42, the NSE 20 at 3,448.73 and the NSE 25 at 5,189.97, all unchanged on the day at 0.00%. Market breadth was weaker than the flat indices suggested, with 20 gainers, 26 losers and 10 unchanged out of 56 tracked counters. In other words, strength in a handful of financial names offset broader softness elsewhere.
Anyone checking the NSE Kenya today snapshot could be forgiven for thinking little happened. But the composition of the session tells a more interesting story. Among the top gainers were Africa Mega Agricorp, up 12.9% to KES 116.0, Eveready East Africa up 7.2% to KES 1.19, BOC Kenya up 6.2% to KES 127.5, then Co-op Bank and KenGen, which rose 4.5% to KES 9.2. On the downside, Sanlam Kenya fell 10.0% to KES 9.0, Eaagads lost 6.8% to KES 29.45, Kenya Re Insurance Corporation dropped 5.8% to KES 3.25, and TPS Eastern Africa Serena slid 5.6% to KES 16.05.
That cross-market dispersion was partly calendar-driven. According to official NSE announcements released on March 27, the market had to absorb audited 2025 results from I&M Group, Co-operative Bank, NCBA Group, Diamond Trust Bank Kenya, Kenya Re, Kenya Airways, Kakuzi and even NSE Plc in a single day. When several large issuers report at once, benchmark indices can stay flat even as capital rotates aggressively within sectors.
Macro also mattered. The Kenyan shilling weakened to 129.75 per dollar, a 0.78% daily move that keeps foreign-exchange pressure firmly in focus for banks, insurers and import-heavy businesses. At the same time, Brent crude fell 3.9% on the day to $103.82 a barrel, though it remained up 3.9% on the week. For Kenya, a net fuel importer, that daily drop offers some relief on energy costs, but the absolute oil level is still high. That is important for reading 2025 earnings: banks have generally held up better than sectors more exposed to fuel, logistics and claims inflation.
Bank earnings dominate as Co-op Bank leads the reaction
The most readable move was in lenders. The 5.7% rise in Co-operative Bank of Kenya suggests the market welcomed its audited 2025 numbers in an environment where Kenyan banks are still benefiting from relatively firm net interest margins, even as investors scrutinize credit costs and funding conditions more closely. The fact that Co-op outperformed in a flat market also points to demand for liquid, defensive names within the Kenya stock market.
This needs to be read as a sector story, not a single-stock one. NCBA Group, I&M Group and Diamond Trust Bank Kenya also released full-year 2025 results on the same day, while the exchange itself launched a Banking Sector Index, according to an NSE press release. That launch is more than a branding exercise. It formalizes the weight of banks in Kenyan equities and gives the market a new benchmark for a segment that already accounts for a large share of local liquidity.

Why are banks drawing this much attention now? First, they remain among the best-positioned listed companies to monetize still-elevated interest rates through lending spreads. Second, a weaker shilling at 129.75 can support institutions with regional operations, foreign-currency income streams or strong corporate franchises tied to cross-border trade. But the same FX weakness can also raise funding costs and increase stress for borrowers with dollar-linked obligations. That means the market is not simply rewarding revenue growth; it is differentiating between balance sheets that can absorb a tougher monetary backdrop and those that cannot.
That is also why search terms such as Equity Bank share price and KCB share price remain useful sentiment gauges for Nairobi even on days when those two groups are not reporting. At the NSE, banks often serve as a real-time read-through on the broader economy: asset quality, credit demand, household resilience, regional trade and the cost of dollars.
Kenya Re falls as investors separate winners from laggards
The flip side of the banking strength was visible in Kenya Re Insurance Corporation, which fell 5.8% to KES 3.25 after releasing its audited 2025 financial statements. Without the full income statement details in the data provided, it would be risky to overstate the reason. But the market reaction points to disappointment, whether on earnings quality, investment income, claims experience or capital allocation. In a high-rate, volatile financial environment, insurers and reinsurers are judged differently from banks: portfolio composition matters as much as underwriting growth.
Other earnings released on the day underscored how varied the drivers are across the Nairobi stock exchange today. Kenya Airways reported audited 2025 results in a context where jet fuel remains highly sensitive to Brent above $100. Even with the day’s 3.9% drop in oil, the weekly level remains demanding for airline margins. Kakuzi, by contrast, sits closer to the agricultural commodity cycle and export demand. Here, the signals were mixed: coffee fell 1.0% to 304.65, cocoa slipped 0.6% to 3,145.0, while wheat rose 0.9% to 610.75. That matters because listed agribusiness names are increasingly being read through a global commodity lens, not just a domestic one.
The exchange also pushed through several structural announcements. NSE launched the Banking Sector Index, said investors will soon gain access to global markets through a Satrix MSCI World Feeder ETF, and appointed Sterling Capital as a market maker in the NEXT derivatives market. These do not change 2025 profits, but they do matter for future market depth, price discovery and retail participation. On a day when aggregate NSE share prices barely moved, those infrastructure developments may prove more consequential over time than the flat close suggests.
Safaricom was not the story today, but it still shapes the market
Even without a fresh announcement from Safaricom on March 27, 2026, it is difficult to interpret Nairobi without accounting for its weight. The safaricom share price today was not the main driver in the data provided, but the company remains one of the exchange’s dominant index components, often accounting for more than 40% of benchmark weight depending on the measure. That means a flat NASI can still coexist with sharp moves in banks if Safaricom itself is steady.
