Your Best Performers Aren't Your Future Leaders
Financial services firms are still spending most of their succession-planning effort on the wrong signal. Korn Ferry's 2026 global succession study found that half of boards admit succession planning began too late during their most recent CEO transition, and only 17% of organisations review succession plans as often as quarterly (Korn Ferry, CEO Succession Readiness Study, July 2026). Bain's latest CEO survey adds a sharper number: fewer than half of chief executives are confident they have the right people in the right roles, or a credible plan to close the gap (Bain & Company, The 2026 CEO Agenda: Where Ambition Outpaces Execution, June 2026).
KPMG's 2026 UK hiring survey shows where firms go instead: outside. Managing Director level is now the single biggest recruitment priority for UK financial services firms this year (KPMG, UK Financial Services Hiring Intentions 2026, April2026). Put simply, firms can't tell who inside the building is ready to lead so they go shopping for someone else's.
The fix isn't more performance data. It's a different definition of what "potential" looks like.
1. Performance Is Only the Starting Point
Strong delivery still gets people noticed, and it should. But it stops being useful as a leadership signal earlier than most talent frameworks assume. Korn Ferry's research is blunt about the consequence: half of organisations report they simply lack a pipeline of "ready now" candidates for their most critical roles, despite years of performance-linked development spend (Korn Ferry, CEO Succession Readiness Study, July 2026).
We see this constantly in the mandates we run. The strongest technical performer on a team is very often not the person who ends up leading it — the two things correlate closely at junior levels and drift apart the higher you go.
Re-ranking last year's appraisal scores and calling it a succession plan isn't planning. It's just paying out the bonuses twice.
2. The Behaviours That Tend to Give It Away
Deloitte's 2026 Human Capital Trends report puts a number on how uncommon genuine adaptability is at senior level: 85% of leaders say building organisational adaptability is critical, and only 7% say their organisation is actually leading effectively through continuous change (Deloitte, 2026 Global Human Capital Trends, March 2026). That's a 78-point gap between what leaders say matters and what they can actually do — and it's exactly the terrain future leaders make their name in. Leading is after all – guiding people through change.
Some people keep operating well when the mandate is vague, the team gets reshuffled, or the strategy changes shape mid-year. You can't see that on an appraisal form. What you're watching is someone who doesn't need certainty to function — and in an industry where restructurings and pivots are now the weather rather than the storm, it's a less common trait than it used to be, and a more valuable one.
Ask less often whether someone hit the number. Ask more often what they did the day the number changed.
3. Exposure Is Key to Understanding Leadership Chops
You cannot tell a strong technician from a genuine leadership prospect without giving them room to show it. Bain's CEO survey found that fewer than half of chief executives believe their organisation can adapt and execute at the speed the market now demands (Bain & Company, The 2026 CEO Agenda: Where Ambition Outpaces Execution, June 2026). No amount of individual talent fixes that if nobody in the building has client exposure, cross-team mandates, or a seat anywhere near where decisions actually get made.
This is also where judging talent purely from inside the firm runs out of road. A competency framework built entirely in-house can tell you how someone compares to their own peers. It has nothing to say about how they'd compare to the market you'll eventually be competing in for that same seat — and that comparison only comes into focus through the kind of original research most internal talent functions were never built to do: mapping who's actually doing comparable work across the market, not just querying who the firm already knows.
Try this test: could you say, with a straight face, how your top three internal candidates would fare against the market for that role? If not, you don't know they're ready. You know they're the best of what you've got.
4. People Leave Quietly, Then Suddenly
High-performance people are disproportionately mobile, and the data on how often firms check in on them isn't reassuring — just 17% review succession plans quarterly (Korn Ferry, CEO Succession Readiness Study, July 2026), which means most go the better part of a year between any real conversation about where someone's headed. Say nothing to a talented person for that long and they'll draw their own conclusion: either you haven't noticed, or you have and you're not moving. Neither reads as a firm worth waiting around for.
Protecting them takes a quarterly rhythm, not an annual one.
A Note of Balance
None of this is an argument for throwing out internal frameworks. Competency models, 360 feedback, and structured development conversations are still the backbone of any credible talent function, and a firm that judges leadership purely by external comparison will get cultural fit wrong just as often as an internal-only process gets capability wrong. The point isn't replacement. Left unchecked against the market, internal judgement tends to grade on a curve that only includes the people already on the payroll.
Conclusion
Identifying future leaders in 2026 means accepting that the firm's own data isn't enough on its own. Performance scores tell you who executed well under conditions you already understood. They say nothing about who'll lead well once those conditions change. The firms getting ahead of this are treating leadership identification like any other high-stakes hiring decision — with real market mapping and comparative research, not another read of the personnel file. In the teams we recruit for across the broader European market, that's usually the difference between a firm that promotes with confidence and one still asking, a year too late, why its best people left before anyone worked out they were ready.
