Performance of the NSE under his tenure: Mwiti took over at a time when the NSE was experiencing one of its worst market routs in years, with delistings, foreign-investor exits and low trading volumes. Media and analyst commentary closely track whether his strategies on new products, data, derivatives and regional positioning can reverse the downturn; this is scrutiny on performance rather than allegations of misconduct.

Pressure to attract new listings and deepen liquidity: As CEO, he faces persistent questions from issuers, investors and policymakers about the slow pipeline of new IPOs and the need to make the exchange more attractive relative to regional and global alternatives. Critics often frame this as a systemic challenge for Kenyan capital markets rather than a personal failing, but he is now the public face of the effort.

Legacy of earlier governance issues at the bourse: Prior corporate-governance and market-structure debates (e.g., on broker collapses, market transparency, and regulation) pre-date his tenure but still shape public perceptions of the NSE. His leadership is therefore judged, in part, on how effectively he can reassure investors and regulators that the exchange is modern, well-governed and resilient.

High expectations around transformation narrative: Through speeches, interviews and social-media presence, Mwiti positions his purpose as providing “transformative leadership to inspire Africa’s transformation.” This bold framing raises expectations that he must deliver visible, measurable improvements at the NSE and in regional market development; any perceived shortfall is likely to draw sharper public critique, even in the absence of ethical or legal controversy.
