More than a quarter of CEOs surveyed said their chief financial officer poses the greatest threat to their job security, ahead of every other C-suite role, according to a new BCG CEO Insomnia Index. The report finds CEOs are relying more heavily on CFOs for decision support, making it critical that finance chiefs are deeply integrated into strategy and execution. However, the CFO's regular interaction with the board can also build credibility and influence, potentially positioning them as a successor, which some CEOs view as a threat.

Why it matters

The pressure on CEOs is intensifying, with the report pointing to an average stress score of 66.7 out of 100, above the threshold typically used to indicate high stress. Growth targets and cost management rank among the top concerns, and a third say they have more to prove to their board now than they did just two quarters ago. This dynamic highlights the evolving role of the CFO and the increasing interdependence between the CEO and finance chief.

The details

The inaugural BCG CEO Insomnia Index, based on a survey of roughly 500 chief executives at companies with revenues ranging from $100 million to more than $5 billion, offers a window into how CEOs assess their stress levels and what's keeping them up at night. More than a quarter of CEOs surveyed said their chief financial officer poses the greatest threat to their job security, ahead of every other C-suite role, followed by the COO. Jody Foldesy, global chief operating officer of corporate finance and strategy at Boston Consulting Group (BCG), views the dynamic less as rivalry and more as interdependence, as CEOs are relying more heavily on CFOs for decision support, making it critical that finance chiefs are deeply integrated into strategy and execution.

What they’re saying

“It is critical that the CFO be deeply integrated into the development of their agenda and provide the right facts, data, and advice.”

The takeaway

This case highlights the evolving role of the CFO and the increasing interdependence between the CEO and finance chief, as CEOs become more reliant on their CFOs for strategic decision-making and execution. However, the CFO's growing influence and potential to be a successor can also be viewed as a threat by some CEOs, adding to the intense pressure they already face.
