Capital Market Assumptions
Endurance Under Pressure
Pressure creates resilience or strain. Our CMAs provide a disciplined, long-term view to help investors build enduring portfolios.
Shifts in geopolitics, technology, and macroeconomic policy are compressing global markets. Effectively navigating these changing dynamics requires a long-term lens and a durable framework.
Our 10-Year Capital Market Assumptions (CMAs) are the building blocks for the development of an investor’s strategic asset allocation. We assess how today’s markets are adapting to structural pressures including sovereign debt burdens, evolving currency dynamics, rapid advances in artificial intelligence (AI), and the continued expansion of private capital. Together, these forces are shaping a landscape where flexibility, durability, and diversification matter more than ever.
Key Highlights
When forming long-term expectations, it’s essential to look beyond cyclical fluctuations and focus on the structural forces shaping trend growth, inflation, and interest rates. Several structural themes are poised to influence the decade ahead.
Developed markets face fiscal strain as higher borrowing costs meet persistent deficits and rising issuance.
Fiscal policy tends to be countercyclical (loosened during economic downturns when the unemployment rate tends to rise) as governments step in to boost aggregate demand. However, we observe that U.S. fiscal policy has become more procyclical (higher government spending during higher GDP growth and lower unemployment), circa the passing of the Tax Cuts and Jobs Act (TCJA). The UK, Germany, and Japan are also seeing elevated debt burdens and fiscal pressures.
Prepare for steeper yield curves and bond market volatility. Stay active in duration and across global sovereign markets.

Shifting trade policies, rising FX hedging activity, and narrowing global growth differentials are eroding support for the U.S. dollar.
With policy shifts reducing the degree of U.S. outperformance relative to the rest of the world, and capital flows becoming more diversified, dynamics reinforce a weaker dollar over the long term.
Over time, we expect the U.S. dollar’s real effective exchange rate (REER) to revert toward its 10-year moving average, driven by the ongoing convergence of global growth rates and rebalancing of trade, the structural rise in FX hedging by international investors, and the dollar’s continued overvaluation relative to long-term benchmarks.
Reassess global currency exposure, hedge ratios and the diversification role of non-U.S. assets as capital flows broaden.

The impact of AI on productivity and competitive dynamics will become more visible.
The biggest beneficiaries of AI adoption won’t simply be the fastest adopters. Winning firms will likely leverage two advantages: strong productivity gains even after widespread adoption and the ability to capture unmet demand where lower prices translate into higher volumes. Sectors that pair these two dynamics together can become important plays in the AI theme. While information technology remains a favored sector under this framework, it also faces disruption with wide dispersion between winners and laggards.
Look toward firms and sectors that can both retain productivity gains and convert lower costs into sustained demand and earnings growth.

Private markets are at the center of an AI-driven capital expenditure boom, facilitating AI adoption and creating significant opportunities for investors.
Private equity and venture capital remain key funders of startups and are well-suited for long-term, active investments in AI infrastructure. They are increasingly complemented by private infrastructure and real estate funds, which offer inflation-linked returns and exposure to secular trends in energy and data. Aligning with the surge in AI adoption, more companies are choosing to remain private for longer, allowing more growth to occur before reaching public markets.
Look beyond traditional public markets to access the full growth opportunity set and be mindful of increasing market concentration in public equities.

Capital Market Assumptions
Our 10-Year Capital Market Assumptions explore how a disciplined, forward-looking approach to strategic asset allocation — grounded in robust capital market assumptions and an understanding of structural changes — will be essential for navigating this environment and capturing long-term value.
Our methodology incorporates projected 10-year returns for each asset class, with expectations driven by key themes across equities, fixed income, alternatives, and currencies. We conclude with guidance on our model construction, detailing how we calculate volatility and correlation, adjust for private markets, and reconcile arithmetic with geometric return measures.
