The Energy Shock Is Moving Into Interest Rates

26 August 2026

Executive Summary

Australia has provided a striking example this morning of how an international energy shock can travel through an economy.

Official July inflation data came in substantially stronger than economists expected.

Consumer prices rose 1.0% during July, while automotive fuel prices jumped 7.5% during the month. Underlying inflation also exceeded expectations.

Financial markets responded immediately.

The market-implied probability of the Reserve Bank of Australia increasing interest rates at its September meeting rose from approximately 17% before the figures to 27% afterwards.

This illustrates an important business-risk transmission mechanism:

Energy disruption → higher fuel costs → inflationary pressure → increased interest-rate risk → potentially higher financing costs.

A company can therefore be affected by an energy crisis even if it purchases relatively little fuel itself.

UK Impact

This matters to UK companies because geopolitical disruption can transmit through international energy markets and eventually into domestic financing conditions.

Businesses commonly model the direct effect of higher fuel prices on:

• Transport.
• Logistics.
• Aviation.
• Manufacturing.
• Distribution.

But second-order consequences can potentially include:

• Interest rates.
• Bond yields.
• Debt-service costs.
• Refinancing.
• Consumer spending.
• Wage demands.
• Property values.
• Investment decisions.

A project that remains operationally profitable can therefore become financially weaker because its cost of capital changes.

Global Impact

Australia’s July figures provide a useful current example.

Fuel prices rose sharply after three consecutive monthly declines, while underlying inflationary pressure was stronger than economists had anticipated.

The transmission mechanism matters globally because energy is embedded throughout:

• Transportation.
• Agriculture.
• Manufacturing.
• Construction.
• Aviation.
• Distribution.

Higher energy costs can therefore feed into prices far beyond the petrol pump.

If those pressures become sufficiently persistent, central banks may respond.

The ultimate commercial consequence can arrive months after the original geopolitical event.

Our View

Businesses should stress-test geopolitical energy shocks through the entire financial chain, rather than modelling fuel costs alone.

Companies should ask:

• What happens if fuel costs rise another 10%?
• What happens if inflation remains higher for longer?
• When does our debt refinance?
• Is borrowing fixed or floating?
• What happens if interest rates rise another 1%?
• Are financial covenants still comfortable?
• Do project models contain realistic interest-rate scenarios?
• Could customers absorb price increases?
• Are wage assumptions still realistic?
• Are suppliers carrying substantial floating-rate debt?
• Could financing costs delay planned investment?
• Are energy and financing risks being modelled together?

Geopolitical risk rarely stays within the category where it started.

An oil disruption may initially appear to belong to the logistics or procurement team.

Several months later, one of its most important consequences may appear on the desk of the finance director.

That is why risk scenarios should follow the consequences all the way through the business.
