Invesco: Global Stock-Bond Return Divergence to Narrow, Correlation to Rise

September 23 — Invesco has released its latest market outlook, indicating that the pronounced divergence between global equity and bond returns observed over the past decade is now shifting. The firm expects overall dispersion between stocks and bonds to narrow, correlations to rise, and market volatility to increase significantly, calling for a fundamental rethinking of traditional asset allocation strategies.

Christopher Hamilton, Director of Investment Solutions for Asia Pacific (ex-Japan) at Invesco, noted that the past ten years were characterized by low interest rates, multiple rate hike cycles, economic growth fluctuations, and periodic crises, resulting in stark return gaps between equities and bonds. Under accommodative monetary cycles, traditional portfolios delivered stable long-term performance but exhibited pronounced divergence. However, as the market enters a new phase, the importance of both income generation and risk diversification in portfolio construction has risen sharply, with cross-asset correlations strengthening.

Three Core Factors Reshaping the Macro Landscape

Hamilton identified three key forces that are reshaping the medium-to-long-term macroeconomic environment and persistently elevating the global inflation baseline — factors that asset allocators must now treat as fundamental variables:

1. Rising fiscal deficits and government debt — particularly in the U.S. and other major economies, providing sustained fundamental support for inflationary pressures.
2. Intentional depreciation of the U.S. dollar — aimed at boosting the U.S. share of global manufacturing output and offsetting high debt burdens, further disrupting global price levels and monetary conditions.
3. Ongoing structural inflation — driven not by full-scale deglobalization, but by regionalization of supply chains, reshoring of manufacturing, and post-pandemic supply chain restructuring.

Against this backdrop, Hamilton emphasized that inflation resistance, income stability, and robust diversification will become the core objectives of portfolio construction going forward.

Structural Shifts in the Dollar Cycle

A notable development is the structural weakening of the decades-old U.S. dollar recycling system. For years, the U.S. leveraged its vast economic scale and resource demand to dominate commodity trade. Oil-exporting countries settled trade in dollars and reinvested dollar revenues into U.S. Treasuries, creating a stable closed loop.

That dynamic has now fundamentally changed. The U.S. has become a net exporter of energy and natural resources. Meanwhile, central banks and resource-exporting nations have been steadily reducing their allocations to U.S. Treasuries while increasing gold holdings. As a result, natural demand for dollar-denominated assets has weakened significantly, raising instability within the dollar system.

Fed Policy Uncertainty and the Case for Gold

Geopolitical conflicts, oil price volatility, and persistent inflation have sharply increased uncertainty around Federal Reserve monetary policy. Wide divergence in market expectations for rate hikes and policy volatility are further dampening global investor appetite for U.S. dollar assets.

In this environment, Hamilton expressed a clear bullish view on gold's long-term strategic value, stating that gold has been upgraded to a core strategic asset capable of effectively hedging against fiscal and monetary policy uncertainty. He also highlighted a historic shift: the current rise in U.S. Treasury real yields is no longer driven by productivity gains, but by an increase in the risk premium on dollar assets. This new paradigm — where gold and real interest rates rise in tandem — further reinforces gold's long-term allocation rationale.

Thematic Investment: AI and U.S.-China Dynamics

On thematic investing, Hamilton stressed that the AI transformation carries both digital and physical dimensions. Infrastructure such as computing power and upstream commodities present clear forward-looking opportunities and will continue to drive global productivity gains.

He argued that the U.S. and China AI ecosystems are more complementary than adversarial, and both offer long-term investment value. In China, AI hardware, applications, and robotics offer substantial growth potential — not only improving regional economic efficiency but also holding the potential for domestic AI technologies and applications to become global standards, offering significant upside over the long term.

Hamilton also noted that current forward price-to-earnings ratios for U.S. tech stocks have fallen significantly from historical peaks, making valuations more reasonable. He emphasized that the current AI cycle is fundamentally different from the dot-com bubble, with corporate earnings capable of supporting current valuation levels.

Outlook: A New Investment Paradigm

Looking ahead, Hamilton expects that rising cross-asset correlations and blurring boundaries between asset classes will become the norm. Investors will increasingly focus on a balanced mix of growth assets and inflation-resilient assets.

"The market environment over the next decade will be markedly different from the past ten years," Hamilton said. "Inflation shocks, policy volatility, and asset convergence will become the new normal. Investors must move beyond traditional allocation frameworks and build more diversified portfolios that are better suited to the evolving macroeconomic landscape."
