When the Bench Runs Dry: Why Boards Are Reaching Back for Yesterday’s CEOs

One in three new chief executives appointed to S&P 500 companies in the first half of 2026 previously ran another public company.

That figure — surfaced by Russell Reynolds Associates and reported by Fortune this month — is not a tribute to the enduring value of experience. It is a distress signal. And it is arriving at a moment when boards everywhere, including in India, need to ask an uncomfortable question: have we done the real work of building a succession pipeline, or have we only done the paperwork?

Pressing the easy button is not succession planning.

When a succession chair falls vacant under pressure, boards face a convergence of risks — governance risk, shareholder confidence risk, operational continuity risk — all at once. Reaching for a retired chief executive who has navigated a public company before feels like the responsible, defensible choice.

It rarely is.

Shawn Cole, president of executive search firm Cowen Partners, described the trend bluntly: bringing back a retired CEO “feels like the easy button to press because conducting a search — if a bench doesn’t exist — is a lot of hard work.” The candour is striking. It reveals something boards seldom acknowledge publicly: many have allowed the bench to go empty.

Part of the explanation is structural. The average tenure of CEOs who departed S&P 500 firms in 2026 reached nine years — up from 6.6 years in the same period last year. Longer tenures are good for continuity. They are corrosive to the pipeline. When the top job is occupied for a decade, the executives who might have grown into it grow impatient. Many leave. The bench does not just thin — it disappears.

The costs of looking backwards are higher than they appear.

Every returning veteran occupies a seat that might otherwise have launched the next generation of leadership. A new CEO appointment cascades: it creates openings at the COO, president, and divisional head levels that become development opportunities for those two rungs below. When an external appointment or a returning retiree fills the top role, those cascading opportunities vanish.

There is a diversity dimension that boards rarely factor in explicitly. The pool of retired Fortune 500 CEOs was shaped largely by the hiring norms of a different era. When boards treat prior CEO experience as the default safety credential, they are often, inadvertently, narrowing their aperture — drawing from a leadership cohort that reflects the demographics and strategic assumptions of decades past.

And there is a strategic fit question. A leader who excelled in a specific competitive cycle brings instincts calibrated to that cycle. In industries being reshaped by technology, regulation, or geopolitical shifts, those instincts may be precisely wrong.

India’s succession gap is hiding in plain sight.

The challenge is not confined to American boardrooms. Across India, 78 per cent of organisations report having formal succession frameworks in place for leadership roles. Yet only 27 per cent describe their succession planning as effective. At the CXO level specifically, the effectiveness rate falls to 18 per cent.

These numbers deserve to sit with leaders for a moment. Nearly four in five organisations have the framework. Fewer than one in five are actually producing ready successors at the executive level.

The gap between having a succession plan and running a succession process is where organisations fail. An annual talent review that produces a slide deck of names is not succession planning. It is a governance gesture. True succession readiness requires candidates placed in stretch assignments, given board exposure, developed through executive coaching, and assessed against the specific capabilities the organisation will need — not the ones that served it in the past.

India’s family-run businesses face this acutely. Only 30 per cent of family businesses globally transition successfully to the second generation; a mere 12 per cent reach the third. Given that family-owned enterprises contribute over 75 per cent of India’s GDP, the succession question is not a boardroom governance issue alone — it is a national economic one.

The Succession Readiness Gap: Two Modes of Board Behaviour

Reactive Boards	Disciplined Boards
Succession reviewed annually in HR cycle	Succession reviewed at every board meeting
Candidates identified, not developed	Candidates placed in stretch roles, coached actively
Pipeline thinned by long CEO tenures	Pipeline refreshed through deliberate rotation
Default to external hire or returning veteran	Strong internal candidates with measurable readiness
Succession seen as an HR responsibility	Succession owned jointly by board and CEO

The board’s accountability is not optional.

Boards that take succession seriously hold themselves accountable for pipeline health the way they hold management accountable for revenue. That means naming two or three credible candidates for each critical role. It means reviewing their development progress — not just their names — at every board meeting. And it means accepting that if the internal answer is repeatedly ‘not ready,’ the board has a governance problem that no external hire will solve.

The decision to appoint an external candidate, or a returning veteran, should be a deliberate strategic choice made from a position of strength — not the only available option when the pipeline fails.

The question worth sitting with is not ‘Who can take over if our CEO leaves tomorrow?’ It is: ‘What have we done in the past twelve months to ensure that question has a strong, internal answer?’ If the honest response is ‘not enough’ — now is the time to act, not when the chair is already empty.
