As inflationary pressures persist and the yield gap widens, CFOs can no longer afford to manage cash defensively. Neil Gallacher, Co-Head of Cash Solutions at MillTech, explains why the transition to a "Total Optimization" model leveraging AI, bank APIs, and asset tokenization is now the only way to safeguard purchasing power and eliminate the silent erosion of idle capital.
As we navigate the mid-point of 2026, the mandate for the modern Chief Financial Officer has undergone a radical transformation. For decades, the treasury function was viewed through a defensive lens: safeguarding assets and ensuring just enough liquidity to meet immediate obligations. However, in an era defined by persistent inflationary pressures and rapid technological breakthroughs, “safe” is no longer a sufficient strategy.
According to Neil Gallacher, Head of Cash Solutions at MillTech, we have officially entered the age of Total Optimization. In this new paradigm, idle cash is not merely a missed opportunity; it is a measurable, unacceptable risk that directly undermines corporate value. For the US and UK-based CFOs who form our core readership, the message is clear: the cost of inertia has never been higher.
The primary driver behind this shift is what Gallacher calls the “silent erosion” of value. While central banks in both the US and UK have fought to bring inflation back to long-term targets, the reality on the ground remains a significant headwind for liquidity managers.
In the UK, inflation remained stubbornly above the 2% target for years, at one point peaking at a staggering 11.1%. As of December 2025, the latest figures sat at 3.4%, still significantly outpacing the Bank of England’s goals. For a US-based CFO managing global sterling balances, or a UK treasurer looking at domestic reserves, the math of holding cash in traditional low-interest accounts simply doesn’t add up.
“Consider a company with £100 million in idle cash,” Gallacher explains. “With inflation at 3.4% and a typical low-interest account yielding just 3%, the business is effectively losing around £400,000 in purchasing power each year. That’s value quietly eroded without a single transaction taking place.”
Beyond the inflation gap, there is the hidden “operational tax” of manual processes. Increasingly complex Know Your Customer (KYC) requirements and onboarding hurdles have historically forced firms to rely on just one or two counterparties. This creates a dangerous overconcentration of risk. In 2026, relying on a limited pool of banks doesn’t just limit your yield; it exposes the enterprise to avoidable counterparty risks that can undermine the very stability the treasury is meant to protect.
The transition from a defensive posture to an optimized one is being fueled by a “triple threat” of technology: Artificial Intelligence (AI), APIs, and Large Language Models (LLMs). Historically, treasury teams spent the vast majority of their time on manual data aggregation, tasks that were inherently reactive and prone to human error. In 2026, MillTech is seeing a massive shift as AI-powered engines begin scraping data sources and documents in real-time. This allows CFOs to move from looking at what happened last month to predicting what will happen tomorrow.
Before the integration of these tools, such tasks were time-consuming and relied heavily on individual interpretation. Now, they are becoming standardized, instantaneous, and highly scalable.
One of the most significant shifts in 2026 is the rise of advanced Treasury Management Systems (TMS) that offer a “Single Pane of Glass” view. For global teams managing portfolios across the US and UK, fragmentation is the enemy of agility.
A unified interface now provides a consolidated view of everything from traditional cash deposits and Money Market Funds (MMFs) to T-Bills and even tokenized assets. Through Bank APIs, these systems eliminate the friction of siloed workflows and outdated manual entry. This convergence has birthed rules-based trading, where liquidity is moved automatically based on pre-set parameters.
“Treasurers can now allocate positions based on cash forecasts alongside real-time data points such as counterparty exposure limits, daily yield, and relationship bias,” says Gallacher. This level of automation does more than just capture yield; it provides a full audit trail and built-in regulatory compliance, helping CFOs meet internal governance standards and external reporting requirements without adding to the headcount.
Perhaps the most transformative trend that is gaining momentum is the mainstreaming of tokenized investment products. By tokenizing MMFs, deposits, and T-bills, corporate treasurers may be able to gain meaningful, practical benefits:
Gallacher suggests that treasurers must manage their risk-return profiles dynamically instead of defensively. The ability to fine-tune duration and credit exposure in real-time allows a treasury to act as a profit center rather than a cost center.
The final hurdle in 2026 is not technological; it is cultural. The role of the treasurer has officially moved from the back office to the strategy room. The single biggest mindset shift required this year is for CFOs to think optimally about making cash work harder.
“The role of a treasurer is no longer transactional but strategic,” Gallacher concludes. “By adopting smarter tools, CFOs can turn cash management into a lever for performance, helping to optimize liquidity and contribute directly to the company’s bottom line.”
No longer bound by slow systems and siloed information, treasury teams now have the tools to act with agility, precision, and control. Those who fail to evolve risk watching their corporate value quietly erode. In 2026, the mandate is clear: Performance is the only true protection.
