UK insolvency risk 2026: How to protect your business from the domino effect

The insolvency domino effect describes how the failure of one business can trigger a chain reaction of financial distress across the wider economy. When a company becomes insolvent, it can leave suppliers unpaid, disrupt customer relationships and reduce confidence across entire networks. In 2026, this risk is heightened by deeply interconnected global supply chains and a prolonged period of elevated insolvencies worldwide. Allianz Trade forecasts that global business insolvencies will rise by +6% in 2026, marking a fifth consecutive year of increases and reinforcing the risk of cascading failures across sectors.

As a result, even businesses with no direct relationship to the original failure can be affected, turning a single collapse into a widespread financial shock.

Despite stabilising after recent peaks, UK insolvency risk remains high in 2026, with around 26,550 companies expected to become insolvent, only a slight decline on previous years. Crucially, this remains around 30% above pre‑2020 levels, highlighting the lasting impact of economic shocks on UK businesses.

The underlying pressures are persistent. High input costs, rising wages and elevated interest rates continue to squeeze margins and limit access to affordable finance. At the same time, structural challenges such as trade barriers and skills shortages are weighing on long‑term growth potential.

While some sectors are beginning to see modest improvement, others remain under strain. Insolvencies are rising in manufacturing, wholesale and B2B services, while sectors such as construction, retail and hospitality continue to operate at historically high levels of distress. This uneven recovery means many businesses are still exposed to late payments, defaults and sudden shocks from customers or suppliers.

How a business failure can impact your company

The collapse of a single business can disrupt your operations in multiple ways, both directly and indirectly. If a customer becomes insolvent, you may face unpaid invoices and immediate cash flow pressure. If a supplier fails, access to key materials or components can be cut off, delaying production and increasing costs.

How a business failure can impact the wider supply chain

However, the wider impact can be even more significant. Today’s supply chains are tightly linked, meaning insolvencies among suppliers and buyers increase the risk of nonpayment and disruption across networks. For example, the failure of one company can destabilise shared suppliers, reduce available trade credit or force sudden changes in sourcing strategies.

How insolvency risks can spread globally

On a global scale, these risks are being intensified by external shocks. Allianz Trade research highlights how geopolitical tensions are driving up energy prices, transport costs and supply chain volatility, putting further strain on businesses with tight margins or high debt levels. In this environment, even a seemingly isolated insolvency can trigger wider disruption, impacting production, increasing costs and putting additional businesses at risk of failure.

Predicting the insolvency domino effect is challenging because modern supply chains are complex, global and often opaque. While many UK businesses have visibility over direct (Tier 1) suppliers, they often lack insight into deeper dependencies where hidden vulnerabilities can build unnoticed. This comes at a time when SMEs are already under pressure from rising operational costs, slowing economic growth and persistent late payments, all of which are weakening resilience across supply chains.

Key Black Swan risks for UK businesses in 2026

Some of the most significant triggers are Black Swan events: low-probability, high-impact shocks that can rapidly disrupt supply chains and trigger insolvency risks. In 2026, Allianz Trade identifies several emerging threats, particularly for SMEs:

• Cyber-driven outages disrupting operations and digital infrastructure
• Geopolitical supply chain disruptions impacting trade flows, energy costs and logistics
• Financial market shocks tightening access to credit and increasing refinancing risk

These risks are becoming more prominent at a time when many businesses remain underprepared to respond effectively.

The financial impact of hidden risk

Compounding this, financial distress is often difficult to detect. Late payments remain a major issue, with UK firms owed around £112 billion in unpaid invoices, while 44% of invoices are paid late, creating sustained cash flow pressure across the economy. By the time warning signs become visible, such as delayed payments or tightening credit, it may already be too late to prevent knock-on effects.

Combined with the interconnected nature of global trade, this makes the insolvency domino effect not only difficult to predict, but also difficult to contain once it begins.

Insolvency risk remains elevated in 2026, with Allianz Trade forecasting 26,550 UK business insolvencies this year, around 30% above pre-2020 levels. Businesses with tight margins, limited cash reserves, high costs or heavy reliance on customer payments are most exposed.

SMEs under cash flow pressure

SMEs are particularly vulnerable as they face rising operational costs, slowing economic momentum, higher payroll expenses, business rate increases and persistent late payments. Late payment is also a major risk.

Sectors facing sustained pressure

Risk varies by sector. Declines in construction, hospitality and retail are being offset by increases in manufacturing, wholesale and B2B services. High input costs, rising wages and elevated interest rates continue to weigh on UK businesses, making firms with weak pricing power more vulnerable.

Businesses exposed to wider shocks

Companies dependent on complex supply chains or external finance are also at risk. Growing Black Swan threats include cyber-driven outages, geopolitical supply chain disruption and financial market shocks. These pressures mean one customer default or supplier failure can quickly trigger wider disruption across the supply chain.

Protecting your business from the insolvency domino effect starts with improving visibility, reducing overreliance and strengthening cash flow resilience. With UK insolvencies forecast to remain elevated in 2026, businesses should take proactive steps to understand where their exposure sits, across customers, suppliers and wider supply chains.

Monitor customer and supplier credit risk

Regularly review the financial health of key customers and suppliers, especially those that represent a large share of your revenue or supply chain. Warning signs may include slower payments, changes in ordering patterns, reduced communication, late filing of accounts or requests to extend credit terms. The earlier you spot signs of distress, the more time you have to reduce exposure.

Reduce concentration risk

Overreliance on one major customer, supplier or sector can leave your business vulnerable if that company fails. Diversifying your customer base and sourcing critical materials from multiple suppliers can help reduce the impact of a single insolvency. It’s also worth looking beyond Tier 1 suppliers to understand whether several partners depend on the same underlying supplier or logistics route.

Strengthen cash flow management

Cash flow is often where the domino effect hits first. Late payments remain a major challenge for UK businesses, with Allianz Trade reporting that UK firms were owed £112 billion in unpaid invoices at the end of 2024, while 44% of invoices are paid late. Keeping a close eye on days sales outstanding (DSO), tightening payment terms where possible and following up overdue invoices quickly can help protect working capital.

Scenario plan for disruption

Ask practical “what if?” questions: What would happen if your biggest customer failed? Could you replace a key supplier quickly? Would you have enough cash flow to cover a major unpaid invoice? Scenario planning helps identify weak points before they become urgent problems.

Consider trade credit insurance

Trade credit insurance can help protect your business if a customer fails to pay or becomes insolvent. It can also provide access to credit risk insight, helping you make more informed decisions about who to trade with, where to extend credit and when to reduce exposure. In a period of elevated insolvency risk, this can be an important tool for protecting revenue, maintaining confidence and supporting sustainable growth.

By combining stronger credit checks, diversified relationships, disciplined cash flow management and trade credit insurance, businesses can reduce their exposure to insolvency shocks – and limit the risk of one failure triggering wider disruption.

Trade credit insurance helps protect your business from customer insolvency and non-payment by insuring your trade receivables. If a customer fails to pay, a policy can indemnify insured losses, helping to protect cash flow, reduce bad debt exposure and limit the impact of one customer failure on your financial stability.

It can also support growth by giving you the confidence to offer credit terms, take on larger orders, trade with new customers and expand into new sectors or export markets – without taking on unmanaged credit risk.
