Rachel Whelan sees treasury transformation less as a technology story than as a redesign of how treasury supports the business. As head of corporate cash management for Asia Pacific, the Middle East and Africa, and global head of payments and transactional foreign exchange (FX) at Deutsche Bank, she works at the intersection of payments infrastructure, liquidity management and cross-border execution. In her view, what has changed most materially is not simply the tools available to treasurers, but the role treasury is now expected to play inside the business.

“Treasurers are now being asked to be strategic partners for the businesses they support,” she said. That marks a meaningful departure from a treasury agenda historically centred on efficiency, control and operational processing.

The underlying environment has changed. Commerce increasingly operates around the clock. Funding costs are more sensitive. Cross-border operating environments are more fragmented. End consumers expect immediacy, while businesses expect treasury to support decision-making rather than simply administer transactions.

That changes how treasury functions are organised. Payments, liquidity and FX are no longer treated as separate treasury functions. The distinctions between execution, liquidity mobilisation and risk management are becoming less rigid as treasury workflows become more integrated.

For Whelan, this is not simply another digital transformation cycle. It is a structural redesign of how treasury operates, how transaction banks support clients and how execution itself is being re-engineered for a faster and more interconnected environment. The larger ambition is real-time treasury rather than faster versions of legacy processes.

Why is treasury moving beyond process efficiency?

For much of the last decade, treasury transformation was closely associated with automation, standardisation and workflow efficiency.

“Before, treasurers were really looking at process automation to get incremental benefits and efficiency,” Whelan said. The focus was operational improvement: reducing manual work, improving visibility and creating more efficient transaction processing.

That agenda has not disappeared. Efficiency still matters, particularly in an environment where liquidity has become more expensive and operating costs remain under pressure.

But Whelan sees a more material shift in priorities. “Now they’re really looking at decision automation linked to business outcomes.”

That distinction matters. Treasury is increasingly expected to support faster and more strategic decision-making rather than simply execute established processes more efficiently.

“They’re using real-time data and richer data to get better insights,” she said. That richer data increasingly comes from payment standardisation efforts, including ISO 20022-driven improvements in payment messaging and structured information quality. Treasury becomes more closely tied to business responsiveness, funding decisions and operational agility.

Why are payments, liquidity and FX becoming one workflow?

One of the clearest structural changes Whelan describes is the collapse of traditional product silos.

“Clients before would have looked at payments, liquidity and FX separately. Now they’re really looking at it together.”

That reflects the practical reality of how businesses now operate. Payments trigger liquidity consequences. Liquidity decisions affect FX exposure. FX execution increasingly needs to happen in line with payment timing and collections flows rather than as a separate treasury activity.

“FX is something treasurers want to see seamlessly embedded into the payments and collections story,” Whelan said.

That changes how treasury infrastructure is designed. Rather than separate systems and distinct operating processes, treasury increasingly requires integrated workflows capable of supporting execution, conversion and liquidity management as part of a connected operating environment.

The implications extend beyond efficiency. Integrated workflows create greater control, faster execution and stronger visibility across treasury activities that were historically managed in more fragmented ways.

Why are cross-border payments being rebuilt through interoperability?

Cross-border payments remain one of the most visible areas of transaction banking transformation, but Whelan’s perspective is notably pragmatic.

Despite enthusiasm around newer infrastructures, digital currencies and blockchain-enabled models, she does not see wholesale replacement of existing payment rails as the most realistic path.

“We are not throwing away the old rails and rebuilding everything.”

Instead, interoperability becomes the more credible operating model.

“It needs to be fully interoperable.”

That reflects how treasury clients actually think about payments. For most, the strategic objective is not adopting a particular technology architecture. It is ensuring that payments move reliably, transparently and efficiently to the right destination.

“Clients want us as a trusted bank to take their payments and route them as efficiently, cheaply and securely as possible,” Whelan said.

Stablecoins may find selective use cases, particularly in more difficult endpoint markets, but her broader argument is that interoperability across legacy and newer infrastructures matters more than technology-led assumptions about wholesale replacement.

Why is embedded treasury becoming more important?

Treasury execution is increasingly moving closer to where business activity actually happens.

“The whole end-to-end ecosystem now has to integrate seamlessly into the client’s systems,” Whelan said.

That reflects broader changes in enterprise operating models. Treasury no longer sits as a detached back-office control function. Payments, collections, FX execution and liquidity decisions increasingly need to connect directly into enterprise resource planning (ERP) environments, operating workflows and business platforms.

Client interaction models are changing accordingly. “Some of our clients are moving towards more APIs,” she said.

That does not imply a single future interaction model. Whelan explicitly describes a multi-channel environment in which banks need to support clients through different integration pathways, depending on how their operating ecosystems evolve.

She also sees banks moving beyond traditional product delivery towards more embedded finance capabilities delivered inside broader client platforms, workflows and commercial ecosystems.

The broader implication is clear. Transaction banks increasingly need to function as embedded infrastructure partners rather than simply transaction processors sitting outside the client’s operating environment.

What role does AI play in treasury decision-making?

Whelan’s perspective on artificial intelligence (AI) is practical rather than trend driven.

“Treasurers can get lost in the buzzword of AI,” she said.

Her focus is less on AI as a standalone technology theme and more on whether it improves decision quality. Treasury increasingly has access to richer structured payment data, stronger visibility and more real-time information. AI becomes useful when it helps convert that into better operational judgement.

“Before, the treasurer used to be reactive.”

“Now they can predict rather than react.”

That predictive capability creates obvious appeal, but Whelan also highlights governance concerns, particularly as more autonomous systems emerge.

“You still need the human in the loop.”

That point becomes even more important as agentic systems evolve. If clients deploy autonomous agents capable of initiating financial actions, while banks deploy their own automated execution layers, controls, accountability and operating safeguards will need to evolve accordingly.

Why does trust become the ultimate differentiator?

For all the structural change Whelan describes, one principle remains constant.

“Clients still need us to be a trusted partner.”

Speed matters, but not at any cost.

“Speed is an ask, but it doesn’t come at the cost of security and finality.”

That is particularly important in more fragmented payment environments where multiple rails, embedded interactions, fraud risks and changing infrastructures increase operating complexity.

Whelan describes the future through the image of a dynamic routing and orchestration layer capable of taking client instructions and determining the most appropriate execution path.

That is a useful description of how the transaction bank’s role is evolving. The differentiator is no longer simply processing payments efficiently. It is acting as the strategic partner providing the trusted orchestration layer between complexity and execution.

For Whelan, treasury’s future is not defined by a single technology or infrastructure shift. It is defined by the ability to combine speed, visibility, intelligence, interoperability and trust into a coherent operating model.
