The war in the Middle East is once again exposing a hard truth for Australian businesses: global shocks rarely stay contained. For SMEs in particular, the impact is not just felt at the bowser – it flows quickly through supply chains, input costs, and working capital cycles.

While fuel price volatility is the most visible pressure point, it is only part of the story. The deeper risk lies in a broader wave of cost inflation and supply disruption across petrochemicals, fertilisers, and industrial components, many of which underpin key sectors of the Australian economy.

The question for SMEs is not whether these shocks will land, but how prepared they are when they do.

It’s not just fuel

Fuel is often the first and fastest indicator of global instability. We have already seen fuel costs rise by around 50 per cent in recent weeks, with further volatility expected. Even with the Government’s decision to halve the excise in the short-term, Australians will still be paying more at the bowser than they budgeted for a month ago.

But beyond fuel, SMEs should be closely watching the flow-on effects into these areas:

• Petrochemical products – plastics, packaging, synthetic materials, lubricants
• Sulphur and fertilisers – critical inputs for agriculture and food production
• Manufacturing inputs – resins, solvents, and industrial chemicals

These products and inputs are embedded in everyday supply chains. When prices spike or supply tightens, the cost impact compounds quickly.

For many SMEs, particularly those operating on thin margins, the risk is not just higher costs, it is the speed at which those costs must be absorbed before they can be recovered.

Exposed Industries

Some sectors will feel these pressures more acutely than others:

• Transport and logistics – directly exposed to fuel volatility, with limited ability to delay cost impacts
• Agriculture – reliant on fertilisers and fuel, both highly sensitive to global supply shocks
• Construction and manufacturing – exposed to petrochemical-based materials and imported inputs
• Food production and distribution – impacted by both upstream agricultural costs and transport

Across these sectors, the common challenge is timing: costs rise immediately, but revenue adjustments lag.

The working capital squeeze

One of the most underappreciated risks in periods of volatility is the strain on cash flow. Many SMEs are asking the same questions right now:

• Can we pass on rising fuel costs, and if so, how quickly?
• If we increase prices today, how do we fund the gap before those higher invoices are paid – often 30, 60 or even 90 days later?
• Are our customers willing, or able, to absorb those increases?

We are already seeing transport operators adapt by shifting from monthly fuel levies to weekly adjustments, reflecting how quickly costs are moving. But even with these mechanisms in place, there is often a lag between cost increases and cash recovery.

At the same time, some fuel suppliers are tightening payment terms, increasing the pressure on SMEs to fund higher input costs upfront.

This is where otherwise viable, growing businesses can come under real stress.

In this environment, invoice finance is becoming an increasingly important tool, allowing businesses to unlock cash tied up in receivables and bridge the gap between issuing higher-cost invoices and actually being paid. By accelerating access to funds already earned, SMEs can maintain liquidity without waiting months for cash to flow through.

Similarly, trade finance can play a critical role where supply chains are disrupted, enabling businesses to secure inventory or inputs upfront, even as suppliers demand faster payment or tighter terms. This can be particularly important for importers and manufacturers dealing with volatile pricing and uncertain supply.

Supply disruption

Price is one side of the equation. Access is the other. Regional businesses in particular may face:

• Fuel availability constraints, which is occurring already, especially in areas with limited supplier competition
• Reduced delivery frequency or supply prioritisation
• Pressure to hold higher on-site fuel reserves, tying up additional capital

SMEs that rely on just-in-time supply chains may find themselves needing to rethink inventory strategies, supplier diversification, and contingency planning.

Building resilience before you need it

Periods of uncertainty reward preparation. For SMEs, that means taking a proactive approach across three key areas:

1. Pricing discipline

Understanding how and when costs can be passed through, and communicating clearly with customers about pricing mechanisms such as fuel levies.

2. Supply chain visibility

Identifying where critical inputs come from, how exposed they are to global disruption, and what alternatives exist.

3. Liquidity and flexibility

Ensuring access to working capital that can absorb short-term shocks without constraining long-term growth.

This is where non-bank solutions are playing an increasingly important role.

Products such as ScotPac’s Line of Credit are designed to give SMEs flexible access to working capital as conditions change. Rather than locking businesses into rigid funding structures, they provide the ability to draw funds when needed, repay as cash flow improves, and respond quickly to cost pressures or supply disruptions.

Alongside this, ScotPac has deep experience supporting SMEs with invoice finance and trade finance solutions, helping businesses stabilise cash flow, fund inventory, and navigate periods of uncertainty in global supply chains.

In an environment where input costs can spike overnight but revenue takes months to catch up, that flexibility can make the difference between managing volatility and being overwhelmed by it.

A more volatile operating environment

The broader takeaway is that global instability is becoming a more regular feature of the operating environment for Australian SMEs.

Whether it is geopolitical conflict, energy market disruption, or supply chain shocks, these events are no longer once-in-a-decade occurrences. They are part of a more volatile, interconnected global economy.

For SMEs, resilience is no longer just about growth, it is about adaptability.

Those that invest in pricing agility, supply chain awareness, and funding flexibility will be better placed not just to withstand shocks, but to take advantage of opportunities when conditions stabilise.

Because while uncertainty creates risk, it also creates openings for businesses that are prepared.
