The Nairobi Securities Exchange (NSE) has significantly revised its derivatives market structure, reducing contract sizes for single stock futures and adjusting margin requirements to improve accessibility for retail investors and smaller institutions.

• Contract sizes for most equity futures were reduced tenfold, effective October 1, 2025.
• The changes aim to lower the cash outlay per contract without diminishing risk-based exposure per share, following a prior review on September 18, 2025, that had increased margins.
• For instance, the contract size for Safaricom has been reduced from 1,000 shares to 100 shares, with the new initial margin for Safaricom at KES 350 for December 2025.
