Inflation, interest rates and the changing investment landscape

As we approach 2027, Australia's economic outlook is being shaped by persistent inflation, elevated borrowing costs and shifting financial market conditions.

We examine the latest economic developments, drawing on Commonwealth Private's November Market Outlook, and what they could mean for Australian households, businesses and investors.

The Economic Outlook

Economic resilience comes at a cost

Despite higher interest rates and global uncertainty, economic activity has remained relatively resilient.

However, continued demand, limited productive capacity and rising energy costs are making inflation increasingly difficult to contain.

CBA Economics forecasts global economic growth of 2.5% in 2026, increasing to 2.7% in 2027, while global inflation is expected to reach 4.7% in 2026.

The challenge for central banks is balancing economic growth against the need to restore price stability.

Higher interest rates are designed to moderate economic activity and reduce inflationary pressures. However, structural challenges such as energy supply constraints, labour shortages and elevated infrastructure spending can make inflation more difficult to manage through monetary policy alone.

As a result, the outlook for 2027 remains uncertain, with economic resilience potentially contributing to a prolonged period of elevated interest rates.

Inflation & Interest Rates

Are interest rates approaching their peak?

Australian annual inflation reached 4.3% in September, with underlying inflation remaining elevated at 3.6%, prompting the RBA to increase the official cash rate to 4.85% in November.

CBA expects the current tightening cycle may be approaching its peak, although persistent inflationary pressures could necessitate further rate increases.

For borrowers, this reinforces the importance of reviewing existing lending arrangements, assessing borrowing capacity and preparing for the possibility of interest rates remaining elevated into 2027.

Higher borrowing costs directly influence mortgage repayments, household disposable income and the borrowing capacity of prospective property purchasers.

For businesses, elevated financing costs can also influence investment decisions, expansion plans and working capital requirements.

Even if the tightening cycle is nearing its conclusion, the timing and extent of any future interest rate reductions remain uncertain.

Financial & Investment Markets

A changing investment environment

Global equity markets have remained resilient throughout 2026, supported by corporate earnings and investment in artificial intelligence.

However, higher borrowing costs and elevated valuations are shifting investor attention towards profitability, cash flow and financial fundamentals.

Meanwhile, higher bond yields are offering more attractive income opportunities for fixed-income investors, creating a changing investment landscape as we approach 2027.

Significant investment in artificial intelligence and supporting infrastructure continues to influence financial markets, particularly across technology, energy and infrastructure sectors.

However, elevated asset valuations can increase sensitivity to changes in earnings expectations, financing conditions and investor sentiment.

For investors, the changing environment reinforces the importance of assessing asset valuations, sustainable returns and the financial strength of underlying investments.

Property, Business & Borrowing Conditions

What does this mean for Australians?

Higher interest rates and persistent inflation are creating a more challenging environment for property owners, investors and businesses.

Property markets: Higher financing costs and reduced borrowing capacity are weighing on housing demand and creating more challenging conditions for property markets.

Business conditions: Rising operating expenses, financing costs and softer consumer spending are increasing the importance of cash flow management.

Investment decisions: Elevated funding costs mean investors need to assess borrowing structures, expected returns and financial risks more carefully.

For existing borrowers, reviewing interest rates, loan structures and available equity may identify opportunities to improve financial flexibility.

For property investors, higher holding costs reinforce the importance of evaluating rental income, cash flow, financing arrangements and long-term investment objectives.

Similarly, businesses considering acquisitions, equipment purchases or expansion should carefully assess debt servicing capacity and the financial implications of additional borrowing.

Looking Ahead to 2027

Positioning yourself for what's ahead

Changing market conditions present both challenges and opportunities for well-prepared borrowers, investors and businesses.

As we approach 2027, reviewing your lending arrangements, borrowing capacity and access to capital can help position you for future opportunities.

Maintaining financial flexibility, understanding existing commitments and considering different interest rate scenarios can help individuals and businesses navigate uncertainty.

For property investors and business owners, preparing financing arrangements ahead of potential opportunities may provide greater flexibility when market conditions change.
