The big picture
Global policy aftershocks: challenges and opportunities
Global policy disruption has been a central focus for financial markets throughout much of 2025. As we enter the final quarter of the year, the major policy shocks feel like they are likely behind us for now, and the focus has shifted to how the world will react to the changes. The aftershocks will continue to reverberate, creating challenges, but also opportunities.
While the new US tariff regime has been largely accepted by the rest of the world, the magnitude of the change should not be downplayed. We expect an effective tariff rate of around 15 per cent in the US, a six-fold increase. That would equate to a tax rise of around 1.5 per cent of GDP, which will have to be absorbed by both businesses and households in the form of lower profits and higher prices respectively. Much of this impact is still to be felt.
We expect the global economy to grow around three per cent this year and next, which is slightly more than three months ago. This mainly reflects a somewhat less negative impact from tariffs on growth in the US and elsewhere. That said, the US economy is likely to grow by far less than in 2024. The country’s main trading partners are also going to be affected, as already seen in a decline in Chinese exports.
We expect the US central bank will reduce its policy rate to three per cent over the next six months, perhaps further. The Bank of England is also expected to lower rates, to 3.25 per cent by the middle of next year, whereas the European Central Bank is unlikely to cut any further. The Bank of Japan by contrast is likely to continue raising interest rates, with a hike expected in the fourth quarter followed by one or two more next year.

What this means for asset allocation
Equities
We see further upside potential for global equities. Our long-standing expectation the US would marginally outperform Europe this year appears to be playing out, and we see this trend continuing over the short to medium term.
The boom in technology share prices driven by investment in artificial intelligence (AI) is an integral part of the case for holding equities, especially in the US. Bullish arguments for stocks tend to highlight that profits and margins are historically high, as are returns on equity and capital expenditure. Bearish arguments usually focus on extended valuations and market concentration. All of the above is largely driven by the boom in AI spending.
That means any structural bull case for equities must start from the premise that rising AI-related expenditure is sustainable. We believe it is.

Government bonds
Market expectations of the future path of interest rates look broadly fair, and we think there is scope for yield curves to steepen given the poor state of various governments’ fiscal positions and market concerns the US government is looking to interfere in monetary policy.
Nonetheless, we have a small overweight position in government bonds, largely reflecting the downside risk to economic growth, after recent data pointed to a deterioration in the US jobs market.
In terms of the outlook for US Treasuries specifically, the main risks to our view are that the domestic economy reaccelerates and/or higher inflation reduces the scope for interest rates to fall.

Credit
Corporate bonds look expensive given the meagre amount of additional yield currently on offer relative to government debt. Then again, while this asset class may offer limited upside potential, it is unlikely to cheapen materially so long as a recession is avoided. After all, supply of new debt pales in comparison with the amount of bonds governments will need to sell. It should be comfortably absorbed by the market.

Private Markets
Privately traded debt has outperformed private equity over the past three years as high yields and healthy illiquidity premia sucked in capital which was left to chase a finite pool of investment opportunities
But as we enter the final quarter of 2025, we expect the tide to turn in private equity’s favour. Investors are showing particular interest in tangible asset-backed investment in infrastructure and real estate, with fundraisers in these two areas having secured more capital from investors in the first half of the year than in the whole of 2024.
Three key investment themes
1. Policy adjustments after the shocks
Economies and markets continue to digest and adapt to several major disturbances seen in the first half of 2025, most notably uncertainty as to the impact of US trade policies, any retaliatory response, and whether supply chains or essential components such as rare earths and magnets would be available at all.
Thanks to fiscal policy loosening in nearly all developed countries, easier monetary policy and the AI boom, we believe recessions should be avoided. But there are risks to the downside if growth slows, or to the upside if the soft patch proves short-lived and investment booms and wealth effects reignite inflationary pressures.

2. AI’s impact broadens across markets, sectors and economies
High valuations and concentration in equity markets have left many sceptical of the ultimate economic and financial benefit of AI. While we have some sympathy for this viewpoint when it comes to the more extreme predictions, we believe AI will be a positive tailwind for markets for years to come.
Business commentary and commitments, actual cash earnings, government initiatives, a strong capex cycle, and positive effects downstream on productivity and margins all suggest the impact will be big and long-lasting.
While returns may so far seem clustered around a small group of mostly US companies, we expect the investments of the biggest tech firms and the productivity potential of the technology will eventually provide strong benefits to a much wider group of companies.

3. US upheaval widens
The first eight months of Donald Trump’s presidency have seen widespread policy shifts with potentially big ramifications. Many federal workers and regulators have been fired, student loans un-cancelled and immigration curbed, just as the labour-market data have been revised down sharply and inflation has risen.
Perhaps most pertinently, US federal debt is big (about 100 per cent of GDP) and getting bigger, while six per cent deficits will not be reined in significantly (see Figure 7). The OECD forecasts general government deficits in the region of 7.5-8 per cent of GDP over the next few years, going even higher in subsequent years.

About the House View
The Aviva Investors House View document is a comprehensive compilation of views and analysis from the major investment teams.
The document is produced quarterly by our investment professionals and is overseen by the Investment Strategy team. We hold a House View Forum biannually at which the main issues and arguments are introduced, discussed and debated. The process by which the House View is constructed is a collaborative one – everyone will be aware of the main themes and key aspects of the outlook. All team members have the right to challenge and all are encouraged to do so. The aim is to ensure that all contributors are fully aware of the thoughts of everyone else and that a broad consensus can be reached across the teams on the main aspects of the report.
The House View document serves two main purposes. First, its preparation provides a comprehensive and forward-looking framework for discussion among the investment teams. Secondly, it allows us to share our thinking and explain the reasons for our economic views and investment decisions to those whom they affect.
Not everyone will agree with all assumptions made and all of the conclusions reached. No-one can predict the future perfectly. But the contents of this report represent the best collective judgement of Aviva Investors on the current and future investment environment.
