Economic and market update
September 2026

Key events in September 2026
- Global share prices fell in September in local currency terms. Rising energy prices, interest rates and bond yields, due to the escalating Middle East conflicts, have led to a more cautious view for share markets. The Iran War has broadened and intensified. The Houthi’s seizure of the Bab-El-Mandeb strait and attacks on the Saudi Arabian oil pipeline have caused further alarm on global energy supplies and inflation risks.
- US share prices edged lower but were partly insulated by optimism on Artificial Intelligence (AI) and corporate profit prospects. US corporates are expected to deliver robust annual profit gains exceeding +29% in the September quarter according to FactSet. Large technology companies such as Alphabet, Amazon, Microsoft, and Nvidia continue to rapidly increase their AI capital investment which is also supporting US economic activity. However, the US central bank raised interest rates by 0.25% in September citing that US inflation “remains elevated.”
- Asian and European share markets fell in accord with a more cautious view on the global energy and political climate as well as central banks in Japan and Europe raising interest rates.
- Australian shares recorded a sharp fall in September. The Technology sector continues to disappoint with a -10% decline. There were also large falls recorded for the Resources sector of circa -5% given lower gold and iron ore prices. The Consumer Discretionary sector remains under pressure as higher oil prices and interest rates are casting a cloud on consumer prospects. There were only two bright spots in terms of a solid +4% gain for the Health Care sector and a modest +0.5% return for the Energy sector.
- The Reserve Bank of Australia (RBA) raised the cash interest rate by 0.25% to 4.60% in September. This is the highest cash interest rate in the past 15 years. The RBA justified raising interest rates given “high inflation” with “upside risks” from rising global energy and technology prices as well as Australia’s capacity pressures. The RBA’s inflation concerns were validated by August’s Consumer Price Index data showing annual headline inflation at 4%.

Key events in global markets over the last three months to September 2026
Global shares (unhedged) made a mild quarterly return of 1.2%. Optimism on AI has been the key driver of rising share prices in the US and select Asian markets. However, the Iran War has generated sharp swings in bond yields and commodity markets over recent months. The brief ceasefire between Iran and the US collapsed in July with the resumption of military strikes and another closure of the Strait of Hormuz as a shipping route.
While global shares have shown remarkable resilience to events in the Middle East this year, this strength is now being tested as the Iran War intensifies once again. Wall Street made historic highs in August but since then has drifted lower. European share markets have displayed a similar performance of strong gains in July and August followed by a more cautious tone. Chinese shares have delivered a subdued quarterly return as weak consumer spending and a struggling property sector weighed on sentiment.
Global bonds (hedged) posted a disappointing -2.4% quarterly return. Concerns over the inflation risk with rising energy prices and persistent government deficits have generated sharp rises in global bond yields this year. Australian bonds have also struggled with the inflation threat by recording a -1.5% quarterly return.
Key events in Australia over the last three months to September 2026
Australian shares made a modest 1.3% quarterly return, but this was a mixed performance across industry sectors. Some of the sectors that were beaten down earlier this year have made a recovery over recent months. The Health Care sector made a remarkable revival with a 25.4% quarterly return as investors considered that Cochlear and CSL had become cheap. There were also strong gains for the Energy sector given the surge in oil and gas prices with the Middle East conflict. The Resources sector also performed well given higher metal prices.
However, there were large share price declines in a range of sectors exposed to the threat of higher interest rates and a consumer spending slowdown. The Consumer Discretionary sector slumped by -10% while the Real Estate sector fell sharply by -8.7%.
Australia’s economy is confronting significant challenges given persistent high inflation and rising interest rates. Consumer spending is slowing as the ‘cost of living’ squeeze continues. Housing prices are now falling given the Federal Government’s announcement of major changes to capital gains tax and negative gearing in May as well as higher mortgage interest rates.
Australia’s high inflation remains troubling and has motivated the RBA to raise interest rates for the fourth time this year in September. Persistent price pressures remain prominent in a wide range of goods and services. Housing costs have increased by 5.7% over the year to August through a combination of higher electricity prices (13.2% annual inflation), new dwelling construction costs (5.4% annual) and rents (3.6%). Healthcare costs have risen by 3.9% and education has increased by 4.7% in the past year. This persistent inflation has seen financial markets expecting another RBA interest rate rise in coming months.
Global prospects
Financial markets remain precariously placed between hopes that AI will drive strong economic growth and corporate profitability and the harsh reality that Eastern Europe and the Middle East remains in turmoil.
The recent escalation of the Iran War and the Russia-Ukraine War presents a severe challenge for the global economy. Shipping costs have surged while there is limited spare capacity in fuel refineries around the globe to produce sufficient diesel and petrol supplies. Should this energy shock intensify further, the pain will spread beyond the service station bowser as both inflation and unemployment dramatically rise. For central banks around the world this creates a major policy dilemma. Do central banks continue to raise interest rates to restrain inflation pressures or lower interest rates to assist economic activity and mitigate rising unemployment?
Regrettably, major central banks are being compelled to raise interest rates to address the immediate inflation threat. The US central bank joined its fellow counterparts in Europe and Japan by raising interest rates in September. Bond markets are now pricing in a sequence of further interest rate rises across the globe to address inflation risks. Global share markets could then prove vulnerable should central banks push interest rates too high and generate a recession that damages corporate profit prospects.
Australia’s persistent price pressures in food, health and housing continue to squeeze budgets. This “cost of living” squeeze is likely to weigh heavily on consumer spending over coming months. Lower house prices will also caution some consumers on their spending.
Given these complex and significant risks, investors should maintain a disciplined and diversified strategy.
