Is your AI investment expanding your margins or just your vendor’s R&D budget? We dive into the "Jevons Paradox" facing modern finance leaders and why protecting your strategic "exclusion zone" is the only way to navigate current transatlantic volatility.
The promise of the last 24 months was simple: automate the routine to liberate the bottom line. Yet, as we move through the second quarter of 2026, many CFOs are finding themselves in the grip of the Jevons Paradox. In economics, this occurs when an increase in the efficiency of a resource, in this case, “intelligence” or “output” actually leads to a rise in its total consumption, driving overall costs up rather than down.
This has created a sharp divergence for CFOs. We are seeing more tasks automated than ever before, but the “cost to serve” is climbing. Licensing fees, compute demand, and the legal complexity of managing AI-driven systems are eating the very margins that automation was supposed to protect.
On paper, the UK economy is showing signs of a “soft landing,” with headline inflation cooling to 2.8% in April. However, for a treasurer or CFO, this is a misleading figure. Sticky services inflation and a surge in public sector borrowing, hitting £24.3bn this April have kept bond yields high. The Bank of England has held the base rate at 3.75%, but with Middle Eastern geopolitical shocks impacting energy markets, the path to lower borrowing costs is narrowing.
Across the Atlantic, the regulatory landscape for US CFOs has become a patchwork. While the SEC formally retreated from its landmark climate disclosure rule in early 2025, shifting toward a voluntary, principles-based framework, the vacuum has been filled by state-level mandates. California’s SB 253 and 261 remain in full effect, carrying penalties of up to $500,000 for reporting failures.
The Insight: Compliance is no longer a federal baseline; it is a geographic strategy. The firms maintaining their margins are those that have stopped waiting for regulatory clarity and have instead adopted a “global-first” reporting standard to satisfy both California’s strictness and the EU’s CSRD requirements.
We are seeing a seismic shift in how technology services are priced a trend that serves as a bellwether for any enterprise heavily reliant on vendors.
Industry leaders like Cyient and Mastek have recently restructured their leadership and delivery models to move away from traditional “time-and-material” billing. In early 2026, Cyient pivoted its entire operational structure to be “AI-led,” focusing on platform-driven growth rather than billing by the hour.
The Warning for CFOs: If your vendors are moving to outcome-based pricing, they are betting that they can capture the efficiency gain for themselves. A Gartner survey found that while 58% of finance functions have now integrated AI, the actual adoption rate has leveled off as leaders struggle to prove a tangible impact on the P&L.
If you are still paying for “man-hours” on a project that a vendor is now completing in minutes with an LLM, you are subsidizing their R&D. The priority now is to audit every service contract signed in the last 18 months and pivot toward fees that reflect results, not time spent.
In strategy, as in design, clarity requires space. We advocate for what we call a Strategic Exclusion Zone: a calculated buffer around your core revenue-driving assets that protects them from being crowded by “fashionable” but low-impact projects.
Currently, too many finance departments are “crowding” their strategy with dozens of minor AI pilots. To regain clarity, we suggest a radical reallocation of focus:
The Core (70%): Protect the assets that provide stability and 30%+ margins. These require the majority of your capital and attention.
The Highlights (10%): Limit high-growth, high-risk bets (like generative AI integrations) to a strictly capped 10% of your resource allocation.
When the “Highlights” start bleeding into the “Core,” you don’t have a transformation strategy you have a margin leak.
The theme for the remainder of the year is “Discipline over Hype.” Consistency builds trust with your board and your investors.
Contractual Renegotiation: Transition your IT and service contracts from “Headcount/Hour” models to “Unit/Outcome” models. Ensure the efficiency gains stay on your balance sheet.
Treasury Hedging: With USD/GBP volatility expected to persist due to international conflict, review your cross-border intercompany loans. Ensure you aren’t over-exposed to a currency swing that could wipe out your Q4 earnings.
Reporting Legibility: If your departmental heads cannot explain their “AI Compute” budget in a single slide without jargon, freeze the funding. In 2026, complexity is where waste hides.
As you look at your 2027 forecasts, are you finding that your “Cost to Serve” is actually decreasing with AI, or is the complexity of the tech eating up the savings?
