Handling FX Volatility in an Age of Geopolitical Uncertainty
Published: February 10, 2026
Tom Hoyle, Head of Corporate Solutions, MillTech, explores how heightened and persistent geopolitical risk is feeding through into FX markets and what this means for treasury teams seeking to protect cash flow and margins in an uncertain environment.
Geopolitical uncertainty has always shaped the global economy, but for UK finance leaders, it is now much closer to home.
In 2026, geopolitics remains the top external risk facing large UK businesses, as it has been for the past three years. Concern levels continue to rise, reflecting a growing sense that political and policy uncertainty is here to stay.
For many businesses, FX is where uncertainty first shows up, turning what looks like a distant headline into a real challenge for cash flow and margins. As a result, FX volatility is increasingly shifting from a background treasury consideration to a core balance sheet risk.
Why geopolitical risk is reflected in FX
Periods of geopolitical tension tend to create uncertainty around trade flows, investment decisions, and future policy direction. Currency markets respond quickly as investors reassess risk and move capital. Faster information flows and automated trading have increased the speed and scale of these moves, often amplifying short-term swings.
For corporates, the challenge is not simply that currencies move, but that they often move before they have time to react. This can leave treasury teams explaining outcomes rather than influencing them.
As a result, FX volatility has moved higher up the agenda for finance leaders. What was once treated as a technical issue is now recognised as a material source of uncertainty, with a direct impact on cash flow, margins, and overall performance.
The impact on corporate performance
The financial consequences of geopolitically driven currency swings are becoming harder to ignore. Nearly half of UK firms reported losses linked to FX volatility over the past year. Trade tensions and tariffs have added to the strain, forcing many businesses to rethink their sourcing and manufacturing strategies in ways that directly affect currency exposure.
Even where underlying demand remains stable, exchange rate movements can quickly erode margins. Cash flow forecasting becomes less reliable, particularly for businesses with international supply chains or overseas revenue streams. Pricing assumptions that looked reasonable at the start of the year can quickly become outdated as currencies reprice.
As volatility becomes more structural rather than cyclical, FX risk is present more consistently, creating ongoing pressure for treasury teams to monitor exposures and respond to market moves with greater speed and confidence.
How businesses are adapting
Many UK businesses are responding by taking a more proactive approach to FX risk management. Hedging levels have continued to rise, with more than three-quarters of firms now hedging some form of exposure. Companies are also hedging a greater proportion of their risk and, in many cases, for longer periods, reflecting a desire for greater certainty over future cash flows.
At the same time, the cost of managing FX risk has increased significantly. This has made it harder for finance teams to rely on manual processes or static policies that struggle to keep pace with fast-moving markets. In response, attention is increasingly turning to technology and automation.
Recent research shows that automation is now one of the top priorities for UK corporates, second only to cost control. Finance teams are targeting automation across key areas of the FX workflow, including reporting, trade execution, and end-to-end risk management. This is about more than efficiency. It is about identifying risk earlier and responding faster when market conditions change.
AI is playing a growing role in this shift. Adoption is accelerating across finance functions, with organisations applying it to process automation, risk identification, and risk management. This trend reflects a broader change in sentiment among finance leaders. More than half have become more optimistic over the past year about AI's potential to improve organisational performance, and almost all expect investment in digital technology to continue rising.
Importantly, this interest in technology focuses on giving treasury teams better tools to see exposures as they build, test scenarios, and execute decisions more consistently. As FX volatility becomes more persistent, the ability to act quickly and with discipline is becoming just as important as the decision itself.
What this means for treasury teams
Geopolitical uncertainty shows little sign of easing, and currency markets are likely to remain unsettled as a result. For corporates, the question isn’t whether FX volatility will affect performance, but how prepared they are when it does.
Treasury teams that invest in better insight, clearer visibility, and faster decision-making will be better placed to manage risk in this environment. That increasingly means combining experience and judgment with technology that supports forward-looking analysis and timely execution.
In a world where uncertainty has become a constant, resilience in FX risk management is now a core requirement for businesses looking to protect cash flow, margins and confidence.
