UK SMEs Market Watch: March 2026
 

UK SMEs are heading into April navigating what increasingly feels like a perfect storm: the growing likelihood of high-impact Black Swan events colliding with mounting cost pressures and subdued economic momentum. From cyber-driven systemic shocks to tightening fiscal conditions at home, businesses are being tested on multiple fronts.

Fiscal tightening and geopolitical volatility are taking their toll on the UK economy. Following a stronger than expected first half of the year in 2025, growth in GDP slowed in the year’s final quarter to just +0.1%, resulting in overall annual growth of 1.3%. This March, the OBR forecasted GDP growth to slow to 1.1% in 2026.

Furthermore, the Federation of Small Businesses (FSB) recently wrote to the Chancellor warning that small businesses face a “perfect storm” of cost pressures, from high energy costs, business rate increases and high employment costs. As a result, over a third (35%) are planning to close their operations or reduce their output in the coming year.

Payroll expenses are again set to rise again in April, with a planned increase in the national living wage (NLW) and the removal of exemptions on statutory sick pay. These follow last year’s hike in employer National Insurance contributions (NICs), which is expected to raise an additional £25bn per year. In addition, many small businesses in England will see their business rates bills rise next month: retail, hospitality and leisure firms will face an average 52% increase over the next three years, according to the FSB.
 

Small businesses are also grappling with a crisis in late payment. UK firms were owed £112 billion in unpaid invoices at the end of 2024, while nearly half (44%) of all invoices are paid late, according to a recent report from the House of Commons Business and Trade Committee. Overall, UK business insolvencies have broadly stabilised since 2024 but remain at an elevated level, according to Allianz Trade data. We expect a decline in overall insolvencies through 2027, but insolvencies are expected to remain above pre-pandemic (2012-2019) averages.
 

Already under pressure, UK businesses face a growing threat from rare, high-impact Black Swan events, according to a recent paper from Allianz Commercial. UK companies rank a global internet outage caused by a major cyber-attack or communication failure, as the most plausible Black Swan scenario for their business in the next five years. This was followed by global supply chain paralysis due to a geopolitical conflict halting the movement of goods and raw materials.

Michael Bruch, Global Head of Risk Consulting Advisory Services, Allianz Commercial: “Black Swan events are now more likely – and far more consequential – than a decade ago. As physical and digital supply become tightly interwoven, disruptions now cascade at unprecedented speed. In today’s fragmented geopolitical environment, companies must strengthen resilience and integrated risk management to withstand the next systemic shock.”

Ranking third in the survey, the sudden collapse of a major financial institution is also a Black Swan scenario concerning UK companies, especially small and mid-sized companies, which rate this risk higher than large companies. Potential triggers for financial market turbulence include geopolitical risks, crises in sovereign debt and/or private credit markets, and a possible AI-equity correction.

“The survey highlights how deeply interconnected today’s global economy has become. A single Black Swan event can trigger cascading effects across businesses, financial markets and economies around the world. Digitalisation continues to intensify these interdependencies,” says Bruch.

Concerningly, just 2% of UK companies consider their supply chains “very resilient”, according to the report. Smaller businesses often lack the resources to build resilience to Black Swan events, yet they are particularly vulnerable to the impacts, says Daniel Muller, Head of Emerging Risks and Trends, Allianz Commercial.

“Smaller companies often find it difficult to invest in resilience to the same extent as larger organisations, because they lack dedicated resources and specialised expertise in areas such as cyber security and supply chain management. As a result, they remain more vulnerable to prolonged digital or operational disruptions. Insurers can play a critical role by helping these businesses strengthen their cyber resilience and make more informed decisions when assessing and selecting critical suppliers,” he says.

While not quite green shoots, there have been some positive signs emerging at the start of 2026. Inflation fell to 3% in January from 3.4% in December, according to the ONS. We also remain more positive on consumer spending thanks to easing inflation, while public infrastructure spending should keep solid momentum.

However, geopolitical events continue to create uncertainty for UK SMEs in areas like energy costs, supply chain disruption and inflation. We expect UK growth to cool in 2026 before picking up slightly in 2027, supported by past monetary easing.
