Oil Shock Pushes Global Borrowing Costs Higher

11 September 2026

Executive Summary

The sharp rise in global oil prices is beginning to transmit directly into borrowing costs and interest-rate expectations, creating a new financial risk for businesses already facing higher energy and logistics costs.

Brent crude rose to around $110 per barrel on Friday after increasing approximately 13% over the week.

The surge reflects escalating disruption around Hormuz and the growing Houthi threat to Red Sea shipping.

Bond markets have reacted sharply.

US 10-year Treasury yields have approached 5%, their highest level in approximately three years.

Government borrowing costs have also risen across:

• Europe.
• Japan.
• Australia.
• New Zealand.

Markets are increasingly pricing the possibility that central banks will have to maintain or increase interest rates because higher energy costs feed back into inflation.

The European Central Bank has already raised rates again this week.

The commercial consequence is important.

The Middle East conflict is moving from a physical supply-chain risk into a financing and balance-sheet risk.

UK Impact

UK businesses should consider exposure through:

• Variable-rate borrowing.
• Refinancing.
• Commercial mortgages.
• Asset finance.
• Working-capital facilities.
• Project finance.
• Trade finance.
• Pension liabilities.
• Investment valuations.

Businesses carrying substantial debt may face simultaneous pressure from:

• Higher fuel costs.
• Higher freight costs.
• Higher supplier prices.
• Higher interest costs.

That combination can affect liquidity significantly even where revenue remains stable.

Property-intensive and capital-intensive sectors may be particularly exposed.

Global Impact

Higher energy prices create an inflationary transmission mechanism.

Fuel becomes more expensive.

Transport costs increase.

Manufacturing inputs rise.

Consumer prices increase.

Central banks then face greater pressure to maintain tighter monetary policy.

Higher interest rates consequently affect:

• Corporate borrowing.
• Government debt.
• Infrastructure investment.
• Property markets.
• Private equity.
• Project finance.

The risk therefore extends far beyond companies that directly consume oil.

Our View

Businesses should stress-test financing assumptions alongside energy costs.

Companies should ask:

• When does existing debt refinance?
• Is borrowing fixed or floating?
• What happens if rates rise another 1%?
• What happens if they rise 2%?
• Are interest-rate hedges in place?
• When do those hedges expire?
• Are financial covenants tight?
• How much headroom exists?
• Are working-capital needs increasing because inventory is being held longer?
• Could higher freight costs increase borrowing requirements?
• Are customers paying more slowly?
• Can capital expenditure be deferred?
• Are new projects still viable at higher discount rates?
• Are suppliers themselves highly leveraged?
• Could financing stress create supplier failure?

The important point is that geopolitical supply disruption does not remain confined to shipping.

It can eventually change the cost of capital for almost every business.
