2025’s Implications for the Future: “Some Like it Hot"?

Key Points

  • The shift away from the low-rate, low-inflation environment of the past 25 years continued in 2025 amid the growing realization that a new regime of higher nominal growth, persistent inflation, and greater volatility has begun.

  • Developed markets face historically high debt levels and structural deficits, which reduces fiscal and monetary policy flexibility. The government’s ability to stimulate growth is increasingly constrained, while inflationary forces persist.

  • Starting valuations remain an important indicator of long-term future returns. With U.S. equities priced for perfection, less-expensive non-U.S. stocks, emerging market bonds, and alternative strategies are positioned for better long-term prospects.

  • Investors may want to prepare for a decade of higher nominal rates, fiscal fragility, and episodic volatility. Navigating this next market cycle might require global diversification, inflation-aware allocations, and a disciplined valuation-based approach.

Introduction

Ten years from now, we will look back on 2025 as a significant transition year. While there were no major market crises reminiscent of the Global Financial Crisis or even the COVID-19 pandemic, 2025 did feel like the tipping point for the next investment cycle. We moved away from anticipating the return of the ultra-low interest rates, low inflation, and ample central bank liquidity environment that defined the past quarter-century and toward accepting higher inflation, higher nominal rates, and increased volatility as the new normal. Nevertheless, investment cycles rarely start and stop at the same moment in time; they tend to overlap. After all, investment cycles are the sum of all individual actions, some of which are on the leading edge that this time is different and others are premised on past conditions resurfacing. So, while some circumstances evolve, indicating the opportunity for future change, some stay the same even as the old cycle dies off.

In this article, we look both back and forward, first at the 2025 capital markets to analyze not just what happened but also how it fits in the historical context and what we believe it means for 2026 and beyond. We then pivot to our return expectations for major asset classes in the next decade. These are anchored in current valuations and will serve as a compass for the road ahead.

exhibit 1

To kick off, Exhibit 1 shows major asset class returns in 2025 and their trailing 10-year averages. U.S. stocks had stellar, double-digit gains, as the S&P 500 capped off the decade with an impressive 15% year-over-year return, far outpacing all other major asset classes.1

While non-U.S. stocks underperformed the U.S. for much of the period, both developed and emerging market equities became the top stars of 2025. They benefited from cheap starting valuations and local currency appreciation versus the dollar, which turned from a perennial headwind into a tailwind. Though U.S. tariff and trade policy may have generated the most headlines, stocks on the other side of the trade policy sloughed them off and pushed higher. To investors’ benefit, this also coincided with a news cycle focused on investment in artificial intelligence (AI), the Magnificent 7, as well as gold and other precious metals. This suggests this trend is not late-cycle hot money chasing returns, and that developed and emerging market stocks still have room to run.

On the fixed-income front, in 2025 U.S. Treasuries experienced little price appreciation, with yields oscillating between 3.75% and 4.75%, as they have since summer 2023. However, while current long bond holders were able to clip nice coupons, for the decade the total return was close to nil.

Ownership by the U.S. Federal Reserve and the U.S. Treasury also has an impact on treasury bond yields. Currently the Fed has about $6.6 trillion on its balance sheet, down from $8.9 trillion in 2022. As Exhibit 2 shows, however, more than $4 trillion in these bonds have durations longer than five years, thus artificially depressing rates even amid quantitative tightening. While full-scale liquidation would send rates higher, the Fed’s current level of holdings feels more like the rule than the exception. In fact, Governor Christopher Waller explained why the Fed should target a balance of about $5.8 trillion, within spitting distance of where it is today (Waller, 2025).

The U.S. Treasury also continues a program to replace long-duration debt with short-term debt, thus putting downward pressure on long-term yields.

Due to ongoing spread tightening, U.S. credit bonds remained ahead of U.S. Treasuries as well as their own 10-year average. A partial cause was supply reduction as in 2024, high-yield issuance fell 45% from its 2021 peak and is now back close to pre-pandemic levels (Roberti, Greene, and Zhou, 2025).
