Small to medium-sized business leaders are operating close to cognitive overload, with a growing focus on cashflow and global volatility adding further complexity as businesses navigate the current environment, according to research commissioned by HSBC UK.

The study of 1,200 business owners and senior decision-makers, conducted in partnership with Professor Pablo Muñoz of Durham University Business School, revealed near-maximum levels of ‘cognitive load’, a structured measure of the mental effort required to run a business across multiple domains including finance, operations and strategy, averaging 15.3 out of a possible 20.

Professor Pablo Muñoz, Professor of Entrepreneurship at Durham University Business School, said: “Running a business is an extreme occupation. It can be deeply rewarding, creative and meaningful, but it also exposes people to a level of responsibility that is difficult to switch off from.

“SME leaders are already operating at near-maximum mental load, meaning most are running close to capacity. When cashflow anxiety is added to that, it compounds the burden and crowds out the headspace needed for strategic thinking. That is not just a personal cost, it is a quiet drag on business potential.”

“If businesses can reduce friction around financial management and improve predictability, it can help ease that burden and give leaders more headspace to focus on their strategic priorities.”

More than half (55%) of SME leaders say cashflow concerns occupy their attention even when they are trying to focus on other responsibilities, while 53% say it makes it harder to concentrate on strategic priorities.

On average, SME leaders spend 43 working days a year thinking about cashflow, liquidity, or working capital, highlighting the scale of both the practical and mental burden associated with financial uncertainty.

This pressure is being amplified by current volatility in global trading conditions. Among internationally active SMEs, half (50%) report increased stress when cross-border conditions are volatile, while 43% cite cross-border cashflow as a source of strain.

The data show that this volatility feeds directly into cognitive overload amplifying the pressures already affecting SME leaders. Even businesses that trade internationally only occasionally report feeling this impact when conditions shift.

These pressures are limiting leaders’ capacity to focus on long-term business priorities and shaping how they make decisions.

As businesses look for ways to reduce this burden, improving how they access and manage working capital is becoming increasingly important. Six in ten (60%) say working capital constraints are holding back their growth ambitions, while over a quarter (27%) have postponed hiring, 22% have delayed investment, and 20% have postponed entering new markets.

SME leaders estimate that, with more predictable access to working capital, they could redirect an average of five hours per week towards growth-focused activity.

HSBC UK has launched TradePay to help address this challenge by simplifying access to working capital and streamlining supplier payments, reducing the day-to-day complexity of managing cashflow.

Stephanie Betant, Head of Trade and Working Capital Solutions, HSBC UK, said: “The international growth opportunity for SMEs is huge but we know they face barriers accessing the capital and support they need to release their full potential.

“It’s not just about access to finance – it’s about reducing complexity, improving visibility and giving business leaders the confidence to make decisions and focus on growth.

“The UK’s SMEs are incredibly resilient. By simplifying trade finance and payment processes, solutions like TradePay can help remove friction, reduce uncertainty and free up valuable time and headspace for businesses to grow and make faster, more confident decisions.”

HSBC customer Dessislava Bell, Co-CEO and Co-founder of Saint and Sofia, said: “As a growing business, managing cashflow and supplier payments is a core part of how we operate, particularly given the seasonal nature of the fashion industry and the need to respond quickly to changing demand. When you’re balancing multiple priorities, cashflow can quickly take up a lot of mental space.

“We work closely with small, independent suppliers, so maintaining strong relationships and paying them reliably is incredibly important to us. Using TradePay has allowed us to take a more proactive approach, giving us the flexibility to invest in inventory and respond to demand, while reducing administrative burden and freeing up time to focus on growing the business.”

Earlier this year, HSBC UK committed to taking its total lending for businesses through its work with UK Export Finance (UKEF) up to £3 billion. By extending its partnership with UKEF, the bank is helping UK SMEs to unlock global opportunities.

Top three tips for reducing business owners’ mental load

Professor Pablo Muñoz suggests there are key steps business owners can take to reduce the cognitive and emotional burden of running a business:

1. Reduce stress where possible through better visibility – Improving visibility over payments and access to working capital can help build financial confidence.
2. Reduce friction in financial management – Simplifying tasks such as payments, approvals and access to working capital – including through digital tools and AI-enabled automation – can ease the day-to-day mental burden on leaders.
3. Protect time for strategic thinking – Creating space for planning and decision-making helps ensure growth priorities are not crowded out by day-to-day financial pressures.
