2025 marked yet another strong year for global investors. Equities delivered a third consecutive year of double-digit returns, despite a sizeable correction early in the year that briefly pushed markets toward bear-market territory. After an extended period without a meaningful pullback, a reset of this kind was both understandable and arguably overdue. Importantly, it proved to be a recalibration of sentiment rather than something more fundamental as risk appetite stabilised, excess positioning cleared, and the market laid the groundwork for the next leg higher. The rebound that followed in April was distinctly V-shaped, and the remainder of the year was largely characterised by a steady push to new highs, supported by strong and broad-based earnings growth.
By year end, the MSCI World Index (USD) was up 21.6%, with global risk assets performing well overall as highlighted in Chart 1. Most major equity markets also posted strong gains in local currency terms, but for USD-based investors the currency backdrop added to their returns picture. With the US Dollar Index down ~10.2% year-to-date, foreign equity gains translated into more dollars when converted back, boosting the USD total return on international indices. However, it is worth emphasising that while FX can meaningfully influence returns over shorter horizons, over longer investment periods these effects tend to mean-revert, leaving underlying corporate fundamentals as the main drivers of returns.
Beneath the headline index returns, 2025 was defined by rotation and catch-up. Leadership broadened as the year progressed, supported by a steadier rate backdrop and earnings strength that extended beyond a narrow set of winners. This shift was visible both in sector dispersion and in the narrowing performance gap between market-cap indices and their equal-weighted counterparts, evidence that returns were less concentrated than in recent years.
