If 2025 taught investors anything, it’s that structural shifts—like the AI revolution—can often outrun geopolitical turbulence. DARRAGH HOGAN, Financial Services Consultant, Milestone Advisory, explores the key themes that shaped 2025, from the rally in precious metals to rising government debt, and provides a strategic outlook for the year ahead
2025 was a year defined by turbulence, transformation, and resilience. Global markets navigated one of the most complex environments in recent decades, shaped by geopolitical uncertainty, trade disruption, technological acceleration, and shifting monetary policy. Early in the year, escalating trade tensions and a dramatic rise in US tariffs (levels not seen since the 1930s) triggered a sharp selloff in April and one of the most volatile weeks in modern stock market history. Yet, in a testament to market adaptability, global equities ultimately closed the year up 6.8% in euro terms, highlighting the resilience of risk assets despite persistent macroeconomic headwinds.
December summed up the contradictions of the year – optimism surrounding artificial intelligence (AI), concerns over rising government debt, and questions around the sustainability of equity valuations all coexisted. International equities, particularly emerging markets, delivered stronger performance than US markets. While the US Federal Reserve delivered a widely expected rate cut, uncertainty remained around the path of policy into 2026.
KEY THEMES THAT DEFINED 2025
Trade, Tariffs and Geopolitics
Trade tensions dominated the early part of the year. The imposition of reciprocal tariffs by the US on approximately 90 countries on 02 April ignited market turmoil and sparked a sequence of retaliatory measures. Although subsequent negotiations and trade agreements brought partial stabilisation, uncertainty around global supply chains and trade policy remained a persistent risk factor throughout 2025.
The AI revolution
AI remained the defining structural theme for global markets. Growth sectors such as Information Technology and Communication Services delivered strong performance, supported by aggressive capital expenditure and robust earnings growth. While concerns emerged late in the year regarding potential overinvestment and valuation excess, AI continued to justify premium pricing and drove markets to record highs, reinforcing its role as a long-term growth rather than a short-term trend.
Currency and the US dollar
The US dollar weakened considerably against the euro in the first half of the year, starting near parity and declining as confidence in US policy stability softened. For European investors, this currency move materially reduced returns on US assets.
Rising government debt and bond market volatility
Government bond markets experienced renewed volatility in 2025 as long-term yields rose across major economies amid widening fiscal deficits. In response, investment managers maintained overweight positions in government bonds while prioritising high-quality credit over lower-rated debt.
Precious metals and real assets
Gold emerged as a standout performer in 2025, driven by geopolitical uncertainty, central bank diversification away from foreign currencies, and shifting interest rate expectations. Silver also rallied strongly, supported by industrial demand and supply constraints. Multi-asset portfolios with strategic gold allocations benefitted materially, reinforcing the role of precious metals as portfolio stabilisers in uncertain environments.
MARKET OUTLOOK FOR 2026: Cautious optimism
The outlook for 2026 is best described as cautiously optimistic. Consensus forecasts point to global growth in the region of 2.8% – 3.3%, supported by resilient US consumption, AI-led investment, and fiscal stimulus across several regions. Inflation is expected to stabilise near central bank targets, though sticky core inflation may limit the pace of rate cuts. The Federal Reserve is expected to continue easing, the ECB may remain on hold, and Japan could see modest tightening.
The bull market case
- Successful AI monetisation supports earnings growth and equity valuations
- Inflation stabilises and consumer confidence improves
- Trade tensions continue to ease through new agreements
- Eurozone growth accelerates via infrastructure and fiscal investment
The bear market case
- Politicisation of central banking undermines policy credibility
- AI-driven overinvestment leads to capital misallocation
- Trade tensions re-emerge and disrupt global growth
- Fiscal stimulus fails to meet expectations
- Persistent geopolitical risks destabilise markets
Strategic implications for investors
For 2026, the fundamental backdrop remains supportive, but risks are elevated. High equity valuations, concentration in mega-cap technology, government debt dynamics, and geopolitical uncertainty all require disciplined risk management.
Markets will continue to reward long-term discipline over short-term speculation. While volatility is likely to persist, opportunities remain abundant for investors who navigate the landscape with structure, diversification, and strategic clarity.
