Economic Outlook 2026: Growth Expectations, Risks, & Equity Market Drivers

As global markets move beyond 2025, attention is increasingly focused on the economic outlook for 2026 and the key forces shaping growth and investment returns. In our first Seaspray Private financial insight for 2026 we examine the global GDP growth expectations across major economies, drawing on forecasts from leading institutions to assess risks, opportunities, and regional divergence. We also highlight equity market performance, with a particular focus on the drivers and detractors of S&P 500 returns in 2025 and the growing concentration in large-cap technology stocks.
