SMF Update
Views from the Aviva Investors' Multi Asset Team
Top 3 investment themes - August 2026
August was marked by a tug of war between strong growth and renewed inflation concerns. Global equities advanced, with the MSCI ACWI rising 1.9% in GBP terms, supported by stronger than expected earnings and continued confidence in the AI investment cycle. Global government bonds fell modestly as bond yields moved higher. Commodity markets were also in focus, with gold rising 9.7% and Brent crude oil gaining 0.4%, both in US dollar terms. Gold benefited from a shifting market backdrop, while oil was impacted by ongoing uncertainty in the Middle East.
August 2026 market performance (GBP Terms1)
How did SMF perform ?
Despite the volatility seen in fixed income markets in the latter half of the month, there were no price adjustments in August which meant that both SMF and SMF II trended upwards in line with their growth rate, delivering 0.6% and 0.5% respectively. Year-to-date, performance remains strong, with the SMF (bond) delivering extremely strong performance following an upwards price adjustment earlier in the year.
Growth assets
It was a strong month for equity markets, with all major regions posting positive returns. Strong economic data and another record-breaking earnings season pushed stocks to fresh highs, with US equities up +2.1% and European equities up 2.0%. Despite bond yields reaching multi-year highs, investors remained focused on the resilience of growth and corporate profits. This provided a favourable backdrop for SMF's globally diversified strategic asset allocation. It was also an exceptionally strong month for our tactical positioning. Regional overweights to the US, Europe, Japan and Emerging Markets all contributed positively to returns. Within our sector positioning, the standout performer was our overweight allocation to European Basic Resources, while overweights to Semiconductors, European Defence and US Energy also added meaningful value.
Defensive assets
Government bonds finished the month broadly flat, as softer economic data offset a late rise in long-term yields. Corporate bonds fared slightly better, returning +0.2%, leaving the fixed income sleeve of SMF modestly positive overall. In currency markets, the US dollar weakened by 0.5%, marking its second consecutive monthly decline as investors weighed the implications of higher borrowing requirements and increased central bank intervention. This was positive for our tactical positioning, with our underweights in the US dollar and pound sterling both adding value. Our overweight position to UK Gilts slightly detracted this month renewed concerns about sticky inflation and potential rate hikes.
Alternative assets
Alternative assets were the standout performers in August. Notably, our allocations to the AIMS total return fund continued to add to performance, demonstrating its benefit in an environment where both equities and bonds struggled. AIMS benefited by having exposure to European Basic Resources following supply chain concerns linked to the continued closure of the Strait of Hormuz, as well as remaining short duration.

Market outlook and positioning: what do we believe happens next?
An exceptional Q2 earnings season in the US has helped anchor market confidence, with earnings growth exceeding 47% year-on-year. More broadly, macro indicators continue to point to a resilient backdrop, with growth holding up better than expected despite mounting geopolitical and inflationary headwinds. The interim deal agreed between the US and Iran has brought down oil prices to pre-war levels, which has reduced inflation expectations. Whilst geopolitical risks remain, the ultimate impact will depend on whether traffic continues through the Strait of Hormuz, a critical global oil supply route.
In our central scenario, inflation risks for 2026 have moved higher while the growth outlook has softened, particularly in energy-importing regions such as the UK and Europe. That said, recent US earnings strength suggests large-cap companies remain well positioned to navigate the current environment.
On interest rates, central banks initially looked through the energy-driven inflation shock, but there has been growing hawkish stance from Central Banks across the globe, already reflected by an interest rate hike by the ECB. In a more adverse high oil price scenario, we cannot rule out further rate increases from the Bank of England or the Federal Reserve. We hold an overweight position to UK gilts relative to US Treasuries given differing rate outlooks.
Against this backdrop, the outlook for equities remains broadly positive, but with a wider range of outcomes. We retain overweight positions in the US, Japan and Emerging Markets, where growth dynamics remain relatively resilient. We also maintain selective exposure to European defence and banks, US Energy, and Semiconductors supported by longer-term structural themes.
We continue to hold an underweight position in the US dollar and sterling, alongside an overweight to the Australian Dollar.
