Investor update

SBS Wealth Market Update - September 2026

9 September, 2026

Patience and skin in the game were rewarded in August 

Equity markets rebounded in August following continued strong corporate earnings out of US companies, driven in large part by Tech companies. Bond markets were volatile, but our diversification saw the fixed interest funds return flat results overall.  

Following the dip in July, KiwiSaver members were once again taught the value of patience and remaining invested. 

What happened in the markets? 

Investors remained focused on the outlook for interest rates, inflation and economic growth, while also assessing the sustainability of strong corporate earnings that have been delivered by many large technology and AI-related companies.

 Geopolitical developments, particularly in the Middle East, continued to contribute to periods of market volatility.  

Global equity markets generally moved higher during the month, supported by the resilient corporate earnings and ongoing investment in AI infrastructure. Technology stocks were once again among the strongest contributors to returns, although markets became more cautious towards month-end as investors reassessed the possibility that interest rates could remain elevated for longer.  

US share markets in particular recorded solid gains, driven by stronger than expected earnings results, and continued optimism around AI-related spending. Investor sentiment was supported by evidence of ongoing economic resilience, although comments from central bank officials later in the month led markets to further set back any expectations of near-term interest rate cuts.  

European markets also delivered positive returns, benefiting from improved economic sentiment and broad-based sector strength. Energy companies were supported by firmer commodity prices, while Financials benefited from the prospect of interest rates remaining higher than previously expected.  

Fixed interest markets faced headwinds as government bond yields rose. Investors increasingly questioned central bank monetary policy and the path of bond yields, particularly in the longer duration. This ultimately led to some weakness in bond prices and performance for many bond sectors. Higher yields are largely reflective of ongoing inflation concerns and uncertainty around the future path of interest rates. 

What happened with our portfolios? 

Wealth and Synergy portfolios were positive for August. 

Both developed markets and emerging markets performed well in August, following the pullback in July. Fixed interest investments were either flat or slightly down on the month, largely in relation to the ongoing questions from investors about the path of interest rates.  

Growth stocks took over performance from value again during August, after the brief flip in July. This was reflective of the overall risk-on environment in August. 

What this means for you 

Staying focused on the long term 

August demonstrated again the importance of remaining patient and having skin in the game, following what was overall a negative July.  

Momentum returned to domestic and global shares, while Australia experienced a pullback – all normal occurrences in a complex but functioning global market. Our diversification across sectors, industries, and regions helped to smooth the ride and produce an overall good month for investors. 

For long-term investors, short-term market movements are expected. What's most important is staying focused on your goals and maintaining an investment strategy that suits your timeframe and needs. 

Three simple ways to stay on track

Keep market movements in perspective  

Short-term ups and downs are a normal part of investing. Your investment strategy is designed to help you achieve your goals over years, not months. 

Trust the value of diversification  

Different investments perform differently at different times. A diversified portfolio helps reduce the impact of any one market or sector falling out of favour. 

Stay focused on your goals 

Your investment plan should reflect your goals, timeframe and circumstances. Periodically reviewing your settings can help ensure you're still on the right path.
