The finance function has spoken. Deloitte’s Q1 2026 CFO Signals survey, which polls 200 CFOs at organisations with at least $1 billion in annual revenues, shows a decisive shift: cost management has become the top internal risk facing large enterprises, and automation is how leaders plan to address it.

This matters beyond finance. When the CFO starts treating AI and automation as the primary lever for controlling costs, it changes how every department justifies its spending.

What the Survey Found

Cost management jumped to first place among internal risks in Q1 2026, cited by 52% of CFOs, up from third place in Q4 2025. Efficiency and productivity, and talent challenges, each came in at 48%.

When asked which tools were most proven for controlling costs, respondents chose automation and technology upgrades at 53%. Increased productivity efforts came second at 43%. In other words, CFOs are not looking for another round of headcount cuts. They are looking for machines to do more.

The technology investment pressure is real on both sides. On the expense side, 49% of CFOs say pressure to invest in new technologies (specifically cloud and artificial intelligence) is one of the top drivers of their cost management efforts. They are spending more on AI while simultaneously expecting AI to save them money. That is a tighter feedback loop than most organisations have run before.

Externally, supply chain disruption topped the list of risks at 52%, just ahead of inflation at 51%, a significant jump from 35% in the previous quarter. CFOs are trying to squeeze costs at exactly the moment when global supply chains are raising them.

The Barriers Getting in the Way

When asked what was standing between their intention to control costs and their ability to actually do it, CFOs pointed to:

• Siloed departments or autonomous business units: 46%
• Outdated technology and tools: 39%

These two obstacles are directly connected. Siloed departments usually run siloed systems. Automation does not work across systems that do not talk to each other. Companies trying to deploy AI agents across fragmented infrastructure are going to hit both problems simultaneously.

This is not a funding problem. These are $1 billion-plus companies. This is a data foundation and change management problem.

What This Means for Business

There are a few things worth unpacking here.

The CFO is now the internal sponsor of AI investment. Historically, AI and automation spending was championed by the CTO or Chief Digital Officer and approved reluctantly by finance. That dynamic is shifting. CFOs are now the ones pushing for automation because they are accountable for costs. This makes the ROI conversation much more direct.

AI has to earn its seat at the table. When automation is your #1 cost control tool, the expectation is that it delivers measurable results. Not productivity scores. Not hours saved in theory. Actual cost reduction that shows up in a quarterly report. Businesses that deploy AI without a clear measurement framework are going to face hard questions from finance leaders by Q3.

The siloed data problem is the real blocker. 46% of CFOs point to organisational silos as their top obstacle. This is almost always a data architecture problem underneath. Teams that cannot share real-time data cannot automate across business functions. Before a company can automate, it usually needs to get its data house in order. The survey does not say that explicitly, but it is what the numbers describe.

SMBs face the same pressures with fewer resources. The Deloitte survey covers companies above $1 billion. But inflation, supply chain volatility, and the pressure to invest in AI are not exclusive to large enterprises. Smaller businesses face the same cost squeeze with less capital to absorb it. The urgency to find efficiency through automation is actually higher at the SMB level.

The Automation Opportunity Is Not Neutral

It is worth being honest about what this survey represents. When 53% of large-company CFOs say automation is their top cost tool, some of those cost savings will come from labour. Not all of them. The survey also shows talent retention as a top risk, which suggests CFOs are not simply planning to replace everyone. But workforce mix will change.

The businesses that will navigate this well are the ones that automate the work that should be automated while upskilling the people who can run, manage, and improve those automated systems. That combination (fewer manual processes, more capable people) is what separates the companies that cut their way to survival from the ones that grow through the transition.

Deloitte will publish a full CFO Signals report in the coming weeks. The Q1 spotlight confirms what most business leaders have already felt: the pressure to do more with less is not easing, and AI automation has become the board-level answer to that question.

The question is no longer whether to automate. It is whether you are doing it in a way that actually compounds your advantage.
