Global markets entered the second half of 2026 with a sense of cautious resilience. After a turbulent start to the year, most major financial markets ended the first half with positive returns, supported by solid corporate earnings, easing energy price pressures and continued enthusiasm around artificial intelligence.
The second quarter marked an important shift in the investment backdrop. Earlier fears of stagflation began to fade after the interim US-Iran deal helped pull oil prices sharply lower. This reduced one of the most immediate inflationary threats facing consumers, businesses and central banks. At the same time, equity markets continued to benefit from strong technology leadership, particularly among semiconductor and AI-related companies.
However, beneath the positive headline returns, several mixed undercurrents remain. Inflation has not disappeared. Government bond yields are still elevated across major developed economies. Equity market leadership remains concentrated in a relatively narrow group of technology companies. And as energy prices stabilise, investors are beginning to focus on a new potential inflation threat: food prices.
A strengthening El Niño weather pattern could become an important issue for the global economy in the second half of 2026. If droughts, heatwaves and erratic rainfall affect multiple agricultural regions at the same time, food inflation could re-emerge just as central banks are trying to manage a careful transition from restrictive policy to gradual, data-dependent easing.
At the same time, the AI investment story is evolving. For the past three years, the market has rewarded the companies providing the infrastructure behind artificial intelligence: data centres, semiconductors, power capacity and cloud computing. The next phase may be different. Investors are increasingly asking where AI is being used, which businesses can monetise it effectively, and which sectors may benefit from productivity gains at the application layer.
For investors, the message is clear: opportunities remain, but selectivity and diversification are becoming increasingly important.
Markets Remain Resilient After a Strong Second Quarter
The first half of 2026 ended on a broadly positive note for financial markets. While returns varied across regions and asset classes, the overall picture was one of resilience.
The most significant macroeconomic development in the second quarter was the interim US-Iran deal, which helped ease tensions in the Middle East and caused oil prices to fall sharply. This mattered because energy prices had been one of the major sources of concern earlier in the year. A sustained rise in crude oil prices would have risked reigniting inflation, squeezing consumers and complicating central bank policy.
Instead, the reversal in oil prices helped reduce stagflation fears and created a more supportive environment for risk assets.
Equity markets responded positively. In the United States, the S&P 500 delivered a gain of around 15% over the quarter, marking its strongest quarterly performance since the post-pandemic rebound in 2020. Technology and semiconductor companies led the advance, with AI-exposed stocks continuing to attract significant investor interest.
Japan was another strong performer. Japanese equities rose by almost 6% in June, supported by ongoing corporate governance reforms and improving corporate profitability. These reforms have helped make Japan more attractive to global investors by encouraging companies to focus more on shareholder returns, capital efficiency and balance sheet discipline.
The UK, by contrast, underperformed. Domestic political uncertainty and still-elevated inflation weighed on sentiment, limiting risk appetite. This highlights an important point for investors: while global market themes matter, local economic and political conditions can still have a meaningful influence on regional returns.
AI and Semiconductors Continue to Lead Equity Markets
Artificial intelligence remains one of the dominant forces shaping financial markets in 2026. The strongest equity returns have continued to come from companies linked to semiconductors, data infrastructure and AI-related computing demand.
The scale of the rally has been remarkable. Key chip indices have more than doubled year to date, reflecting the market’s belief that AI will drive a multi-year investment cycle across hardware, cloud infrastructure, data centres and energy capacity.
This enthusiasm is not without justification. AI adoption continues to expand across industries, and businesses are investing heavily in the tools and infrastructure required to support it. The demand for advanced chips, high-performance computing and reliable data centre capacity remains substantial.
However, the strength of the rally also raises important questions. Market leadership has become increasingly concentrated, with a relatively small group of companies driving a significant portion of overall index returns. This concentration can create vulnerability if earnings disappoint, valuations become stretched or investors begin to question the pace of future growth.
A strong long-term theme can still experience short-term volatility. For that reason, investors may benefit from exposure to AI-related growth, but that exposure should be sized carefully and balanced with diversification across regions, sectors and asset classes.
Bond Markets Stabilise but Yields Remain Elevated
While equities attracted much of the attention in the second quarter, bond markets also played an important role in shaping the investment landscape.
Government bond yields remained relatively elevated across major developed economies through June. This reflects several lingering concerns, including persistent inflation, high fiscal deficits and uncertainty around the timing of central bank rate cuts.
That said, the easing of stagflation concerns helped stabilise bond markets. With oil prices falling and inflation pressures moderating, investors became more confident that the policy environment is gradually shifting away from aggressive tightening and towards cautious easing.
This does not mean central banks are likely to cut rates quickly or in a synchronised manner. Instead, policymakers are signalling a more careful, data-dependent approach. They want to avoid easing too early and allowing inflation to return, but they also recognise that overly restrictive policy could weigh on growth.
For investors, higher-quality sovereign bonds are beginning to regain appeal as portfolio diversifiers. After such a strong, technology-led equity rally, government bonds can provide balance in portfolios, particularly if equity markets experience a setback.
Corporate credit conditions also remain broadly healthy. Default expectations are still benign, and corporate balance sheets are generally solid. This supports the case for selective credit exposure, although investors should remain mindful that credit spreads can adjust quickly if growth expectations weaken.
Commodities: Oil Falls, Gold Weakens and Industrial Metals Find Support
Commodity markets have also shifted meaningfully.
Oil prices fell sharply after their earlier surge, recording their steepest quarterly decline since the pandemic. This helped ease inflation fears and reduced pressure on consumers and businesses. Lower oil prices also weighed on energy stocks, which lagged the broader equity market during the quarter.
Gold weakened as risk appetite improved. When investors become more comfortable holding equities and other risk assets, demand for defensive assets such as gold often softens. However, real yields remain relatively elevated, which continues to influence the outlook for precious metals.
Industrial metals, meanwhile, are benefiting from structural demand linked to AI infrastructure, electrification and digital networks. Data centres, renewable energy projects and grid upgrades all require substantial investment in physical infrastructure. This creates long-term demand for metals used in power systems, construction, batteries and digital connectivity.
However, investors are beginning to ask whether recent price strength in some metals has moved ahead of fundamentals. This is a familiar tension in markets: a powerful long-term theme can support prices, but valuation and timing still matter.
El Niño Could Become the Next Inflation Shock
As energy markets stabilise, attention is shifting toward a different potential source of inflation: global food prices.
A strengthening El Niño weather pattern could raise the risk of a broad-based, weather-driven supply shock in the second half of 2026. El Niño events are not unusual, but this one matters because of its expected intensity, timing and global reach.
If severe weather affects several major agricultural regions simultaneously, the result could be more than a routine seasonal disruption. Droughts, heatwaves and erratic rainfall could affect Asia, Africa, Australia and the Americas at the same time, putting pressure on a wide range of crops.
The main concern centres on grains, livestock and palm oil.
Wheat, maize, rice and soybeans are essential to global food supply. If weaker monsoons affect India and Southeast Asia, while drier conditions hit Australia, Southern Africa and South America, staple crop prices could rise. This would be particularly difficult for emerging markets, where food accounts for a larger share of household spending.
Livestock producers could also face pressure. Heat can reduce animal productivity, while higher grain prices increase feed costs. This combination can lead to higher meat and dairy prices.
Palm oil is another important area to watch. Indonesia and Malaysia dominate global palm oil supply, and both countries typically experience drier weather during El Niño. Any meaningful reduction in output could affect vegetable oil prices and spill over into processed foods, consumer products and household staples.
For central banks, this creates a difficult challenge. Even if energy inflation fades, food inflation can still affect headline inflation and consumer expectations. Moderate food price increases may be uncomfortable if they arrive while inflation is still above target in many economies.
Why Food Inflation Matters for Investors
Food inflation is not only a consumer issue. It can influence monetary policy, corporate margins, political stability and market sentiment.
For households, higher food prices reduce disposable income. This can weaken consumer spending, particularly in lower-income economies or among price-sensitive consumers.
For companies, higher input costs can pressure margins. Food producers, retailers, restaurants and consumer goods companies may need to decide whether to absorb costs or pass them on to customers. Either choice can affect profitability or demand.
For policymakers, food inflation can be politically sensitive. Rising food prices often attract public attention more quickly than other forms of inflation because they affect daily life directly.
For investors, the key issue is whether food inflation remains contained or becomes persistent enough to alter central bank behaviour. If policymakers become concerned that food price shocks are feeding into broader inflation expectations, they may be slower to cut interest rates than markets expect.
This is why El Niño deserves close attention in the second half of 2026.
The AI Story Is Moving From Infrastructure to Monetisation
The second major theme for investors is the changing nature of the AI opportunity.
For the past three years, the AI investment story has largely centred on infrastructure. Hyperscalers and major technology companies have committed hundreds of billions of dollars to data centres, semiconductors and power capacity. Investors have rewarded the companies supplying the “picks and shovels” of the AI build-out.
That infrastructure story remains important. AI still requires enormous computing power, advanced chips, cloud infrastructure and reliable electricity. However, market attention is beginning to widen.
The key question is no longer only how much money is being spent on AI capacity. Investors now want to know what that capacity is being used for and whether it can generate measurable revenue.
This marks an important transition. The first phase of AI investing rewarded companies building the foundations. The next phase may reward companies that can use AI to improve productivity, generate recurring revenue and deliver clear operational benefits.
Enterprise AI Adoption Is Accelerating
Enterprise spending on AI applications is growing quickly. Businesses are moving beyond experimentation and are increasingly willing to pay for tools that deliver measurable value.
This is different from previous technology cycles. Many companies are choosing to buy AI solutions rather than build them internally. AI-native tools are also converting trial users into paying customers at a higher rate than traditional software, suggesting that businesses see practical value in these applications.
The focus is shifting from innovation for its own sake to return on investment.
Companies want AI tools that can reduce costs, improve customer service, automate workflows, enhance decision-making or unlock new revenue opportunities. This creates opportunities for businesses that can turn AI capability into practical solutions.
Banking, Healthcare and Utilities Show Where AI Is Gaining Traction
Several sectors illustrate how AI is moving from theory to application.
In banking, AI is becoming embedded across fraud detection, credit decisioning, customer engagement and workflow automation. Financial institutions are increasingly judged not simply on whether they have adopted AI, but on whether they have integrated it into operations at scale.
In healthcare, AI adoption is also accelerating. Diagnostic imaging, clinical documentation and administrative automation are among the most mature use cases. More than 1,000 AI-enabled medical devices have already been authorised by regulators, indicating that the emphasis is shifting from technical novelty to proven clinical and operational benefit.
Utilities occupy a more complex position. They are both beneficiaries of AI-related demand and adopters of AI tools. The growth of data centres is placing increasing strain on power grids, creating demand for generation, transmission and grid upgrades. At the same time, utilities can use AI to improve forecasting, maintenance, efficiency and customer service.
These examples highlight the broadening AI opportunity. The next phase of the market may not be limited to semiconductor companies and cloud infrastructure providers. It may also include businesses that can apply AI effectively within their industries.
What This Means for Portfolio Positioning
The investment outlook remains constructive, but not without risks.
Global growth has moderated but remains ahead of earlier expectations in several developed economies. Labour markets are reasonably firm, consumer spending is steady and business investment continues to support activity. Inflation is trending lower, helped by the decline in energy prices, but central banks remain cautious.
Equities continue to benefit from structural growth themes, including AI-driven productivity, digital infrastructure and green capital expenditure. Corporate profitability remains broadly healthy.
However, investors should also recognise the risks. Equity gains are concentrated. Geopolitical tensions remain unresolved. Food inflation could re-emerge. Bond yields remain elevated. And the AI trade, while powerful, is evolving into a more selective phase.
This environment supports continued exposure to growth assets, but with discipline.
Diversification across asset classes, regions and sectors remains essential. Investors should avoid building portfolios around a single theme, even one as powerful as AI. The most compelling opportunities may come from combining exposure to long-term growth trends with careful risk management and valuation discipline.
Conclusion
The second half of 2026 begins with markets in a stronger position than many investors expected earlier in the year. Lower oil prices, easing stagflation fears and continued AI enthusiasm have supported risk assets, while corporate earnings remain resilient.
Yet the outlook is not without complications.
A potential El Niño-driven food shock could create a new inflation challenge. Central banks are likely to remain cautious, even as energy prices ease. Bond markets may provide better diversification benefits, but yields still reflect concerns about inflation and fiscal deficits. AI remains a major investment theme, but the focus is shifting from infrastructure build-out to real-world application and monetisation.
For investors, the key is balance. There is still reason to participate in growth opportunities, particularly those linked to AI, digital infrastructure and productivity improvement. But portfolios should also be prepared for renewed volatility, inflation surprises and shifting market leadership.
In an environment where resilience and risk exist side by side, disciplined diversification remains one of the most important tools available to long-term investors.
