UBS identifies AI, resources, and longevity as key drivers of future global markets amid sustainability shift

UBS’s chief investment office says three structural themes are likely to continue shaping global equity markets over the coming years: artificial intelligence, power and resources, and longevity. The bank groups these as its transformational innovation opportunities, or TRIOs, and argues that each one is tied closely to the sustainability transition and to areas where corporate earnings could be supported by secular demand rather than short-lived cycles.

That view rests partly on the scale of the investment needed to keep the world on track for lower emissions. The International Energy Agency has said annual clean energy investment would need to rise to about US$4.5 trillion by 2030 if the net-zero pathway is to remain viable. UBS also points to the 2026 Zurich Climate Week, where attention centred on the role of physical infrastructure in both decarbonisation and adaptation. As electrification spreads across industry, transport and heating, the need for new grid capacity, more resilient transmission systems and better software to manage distributed power is becoming more urgent.

In UBS’s view, that should support demand for suppliers of cables, transformers, switchgear and grid management technology. These are not simply climate-related businesses, the firm argues, but core enablers of energy security and system resilience as extreme weather and higher electricity consumption place greater strain on existing networks.

The bank has been consistent in promoting transformational innovation as a source of long-term market returns. In earlier research, it said the artificial intelligence market could reach US$3.1 trillion by 2030, while the longevity theme could expand from US$5.3 trillion in 2023 to US$8 trillion by the end of the decade. UBS has also highlighted the build-out of data centres and the resulting pressure on power systems as a major reason capital is flowing into grid modernisation and energy infrastructure.

Within sustainability, UBS says investors can gain exposure across multiple asset classes, including equities, bonds, hedge funds and private markets. It argues that sustainable strategies have historically delivered return patterns similar to conventional allocations, though with different risk profiles, particularly in alternatives. The firm also says long-term performance is more likely to be driven by fundamentals and the broader economic backdrop than by politics.

In equities, UBS sets out several routes for sustainable investors: companies providing direct solutions to sustainability or climate-transition problems; businesses with stronger operational sustainability credentials than peers; firms that can improve over time; and strategies that use active engagement to push issuers towards better outcomes.

On the fixed-income side, the bank points to sustainable bond strategies, municipal bonds earmarked for environmental or social projects, securitised assets with relevant criteria, development finance exposure through multilateral institutions such as the World Bank, and emerging-market finance vehicles designed to channel private capital into development needs. It also notes that thematic bonds, including green, social, sustainable and sustainability-linked debt, can fund both environmental projects and transition plans.

For investors willing to take more risk, UBS says sustainable hedge funds may exploit pricing inefficiencies linked to environmental, social and governance issues. In private markets, it sees climate technology as an important opportunity, particularly for early-stage and growth-stage companies that need capital to commercialise decarbonisation technologies. It also points to co-investments alongside experienced managers and secondary markets as ways to improve access or liquidity, though it warns that private assets can bring leverage risk, defaults, concentration and limited disclosure.

Renewables remain central to the bank’s thesis. UBS notes that the IEA now puts their share of the global energy mix at 35%, with that figure forecast to rise to 46% by 2030. Cost declines have made renewables competitive with fossil fuels since 2015, and UBS says solar in particular remains attractive because manufacturing improvements have lowered prices and scale should continue to support long-term cost advantages.

Even so, the firm cautions that private market investors need to accept illiquidity and less control over holdings. Its broader message is that the sustainability transition is not just about policy or preference, but about a set of infrastructure, technology and financing needs that are likely to keep attracting capital for years.
