How will politics shape markets in 2026?

Political headlines will remain front and center in 2026, but history suggests their impact on financial markets is often short-lived. While trade policy, domestic politics, and geopolitics contributed to volatility in 2025, investors have since refocused on solid economic fundamentals, falling interest rates, and structural growth trends like AI.

Trade policy will stay in the spotlight 

The US Supreme Court is set to rule on the administration’s use of IEEPA for tariffs, potentially affecting around 70% of tariff revenue. If current tariffs are overturned, new, more targeted tariffs are likely, increasing policy uncertainty and volatility, especially if trading partners retaliate. However, a divided US Congress—probable after the midterms—could limit major shifts in trade policy.

Leadership changes are also in focus

The Fed will get a new chair in 2026, with challenges ahead given high inflation and debt, but we expect monetary policy to remain broadly supportive for markets. The US midterm elections in November will add to headline risk, with all House seats and one-third of Senate seats up for grabs. While political rhetoric may intensify, history suggests markets typically look past election cycles. Current odds suggest a divided Congress, which would likely result in legislative gridlock and limit the scope for major policy changes on trade, fiscal stimulus, or financial regulation.

Globally, political risks persist

In Europe, attention will center on political stability in France and the UK, while the Russia-Ukraine war and tensions in the Middle East are likely to persist. In Latin America, elections in Chile, Colombia, Peru, and Brazil could reinforce the region’s shift toward right-leaning governments. Asia’s political calendar is quieter, but Japan’s fiscal policy decisions and China’s new Five Year Plan—emphasizing growth, security, and technology—will be closely watched.

Key risks

What risks could bring markets back to earth in the year ahead? The most prominent in our view are: 1) a potential disappointment in AI progress or adoption, 2) a resurgence or persistence of inflation, 3) a more entrenched phase of US-China strategic rivalry, and 4) the (re)emergence of sovereign or private sector debt concerns.

An AI disappointment

We believe current investor enthusiasm for AI is justified by strong capital spending, innovation, and adoption. But valuations are high, markets have rallied strongly, and no investment boom has ever seen capital spending perfectly match future demand. The AI rally may face periods in 2026 when investors fear excess investment, bottlenecks, or obsolescence. Broader risks could emerge if refinancing dries up, triggering defaults or threatening financial stability.

A return of inflation

The inflation impact of US tariffs has matched expectations, though tariff evasion may be higher than anticipated. A risk for 2026 is that second-round effects—US ­companies raising prices or profit-driven inflation—could make inflation more persistent and harder for the Fed to ignore, limiting its ability to respond to risks and potentially keeping long-term yields elevated.

US-China conflict

The US-China rivalry intensified in 2025. Ongoing competition suggests further brinkmanship will remain a risk through 2026, especially around tariffs, rare earth exports, and AI chip sales. So far, escalations have ended in negotiated agreements, reflecting incentives to avoid prolonged disruption.

Debt concerns 

In 2025, global bond investors repeatedly flagged rising government debt, with episodes of higher yields in the US, France, Japan, and the UK. If governments fail to reassure markets on borrowing and inflation risks, or pressure central banks to cut rates, yields or currency volatility could rise. Rapid yield increases would pose risks to equity markets. Investors should also monitor both public and private credit markets, where tight spreads and looser lending standards may have created vulnerabilities.

Several factors could lead to market weakness

Bear scenario (Disruption)

Bear scenario (Disruption)

 

AI

Bull scenario (Tech boom)

Robust, broad-based AI spending and rapid adoption. Monetization exceeds expectations, driving productivity and corporate profits. “Agentic” and physical AI applications accelerate, fueling optimism and further investment.

Base case (Solid growth)

Solid AI investment continues, with steady adoption and gradual monetization. Productivity gains are incremental, supporting business sentiment but not transforming macro growth.

Bear scenario (Disruption)

AI investment stalls or contracts due to disappointing monetization, technical setbacks, or obsolescence. Corporate caution leads to reduced capex and slower adoption.

 

Economy

Bull scenario (Tech boom)

US growth outpaces trend, led by strong consumption and business investment. Unemployment remains low, wage growth is healthy. Other major economies benefit from global tech spillovers and easing trade tensions.

Base case (Solid growth)

US grows at its 2% trend rate; labor market softens but unemployment stays below 5%. Consumption is resilient. Growth in Europe and China is supported by targeted fiscal stimulus.

Bear scenario (Disruption)

US growth slows sharply—below trend or even flat—due to lagged tariff impacts, weaker consumption, and spillover effects. Other major economies also weaken; risk of recession rises.

 

Policy

Bull scenario (Tech boom)

US tariffs fall below 10%, reducing trade friction. Possible Russia-Ukraine ceasefire boosts global sentiment. Central banks maintain or tighten policy only modestly; credit spreads tighten.

Base case (Solid growth)

Fed cuts rates toward 3-3.5% as inflation stabilizes near targets. US tariffs remain in the high teens, but retaliation is limited. Fiscal stimulus in Europe and China supports growth.

Bear scenario (Disruption)

Central banks respond aggressively: Fed cuts 200–300bps. Policy focus shifts to crisis management. Credit spreads widen. Trade tensions and inflation risks persist.

Messages in Focus

Hedge market risks

Investors should consider a diversified approach to hedging market risks. Holding sufficient liquidity can help investors avoid forced selling. Quality bonds offer attractive yields and can buffer portfolios. Gold’s diversification benefits remain important. Periods of low volatility can also provide an opportunity to lock in gains while maintaining upside potential through structured investments.

Messages in Focus

Diversify with alternatives

Including alternatives can enhance diversification, provided investors understand their liquidity needs and the features of the asset class. We recommend a 20-40% allocation in endowment-style portfolios. For 2026, we see hedge funds benefiting from low stock correlation, high return dispersion, and increased M&A activity; in private equity, our focus is on middle-market buyouts, carveouts, and secondaries, while select direct lending and private real estate and infrastructure offer attractive income, diversification, and exposure to structural trends.

Building an effective alternatives allocation

Investors with a long-term horizon and an “endowment” investment style may benefit from allocating up to 20-40% of their portfolios to alternatives such as hedge funds, private markets, and infrastructure. The optimal allocation depends on individual risk tolerance, liquidity needs, and long-term objectives, but a well-structured alternatives allocation can enhance diversification and improve risk-adjusted returns.

Effective diversification across alternative strategies is essential to maximize their benefits, in our view. By investing in a mix of hedge funds, private equity, private credit, and infrastructure, investors can access varied sources of return and reduce potential downside risk. A balanced approach ensures the portfolio remains resilient and adaptable to changing market conditions.

Manager selection is especially important in alternatives. Investors should therefore prioritize high-quality hedge funds with strong track records, private market funds with robust governance and expertise, and infrastructure assets offering stable cash flows. Those making smaller allocations may benefit from fund-of-funds or evergreen solutions, while larger investors may prefer a diversified selection of single managers.

Can AI power the market even higher?

AI-linked innovation has been the engine of the market’s ascent in recent years. Investors should remain mindful of the risks inherent in any investment boom. Yet, we believe that powerful trends in capex and accelerating adoption are likely to drive further gains for AI-linked stocks in the year ahead.

The economic backdrop

We expect the economic backdrop to be supportive of stocks in 2026. Growth enters the year somewhat uneven, but as the year evolves, we expect business and consumer confidence to improve, fiscal stimulus in major advanced economies to gain traction, and tariff effects to fade.

How will governments manage rising debt?

In some countries, current policies mean government spending is at “escape velocity” and will continue rising as a share of GDP unless decisive action is taken. We believe “financial repression”—a regime that channels savings and central bank funds into government bonds, suppressing yields—is likely to become more common in coming years.

Our currency views for 2026

Entering 2026, we see persistent US twin deficits and declining interest rates continuing to weigh on the dollar, especially as rates elsewhere remain stable. Against this backdrop, we favor long positions in the euro, Australian dollar, and Norwegian krone versus the USD. Our preference is for high-yielding currencies, which should benefit as risk appetite broadens in FX markets over the next year.
