The "Calm" and Undercurrents of Global Financial Markets: Asset Allocation Considerations for Long-Term Investors

The "Calm" and Undercurrents in Global Financial Markets: Asset Allocation Considerations for Long-Term Investors

In October 2025, the Reserve Bank of Australia (RBA) released its latest *Financial Stability Review*, depicting a "stable but fragile" global macro-financial environment. In April this year, a new round of tariff shocks triggered sharp declines in asset prices, but markets recovered quickly within a few months, and investor sentiment warmed. However, risk premia have been compressed to historic lows, while issues such as stock market concentration, hedge fund leverage, and liquidity mismatches at non-bank financial intermediaries remain hanging overhead. Identifying these structural risks is becoming a key prerequisite for institutional investors as they formulate asset allocation frameworks for the next 3 to 10 years.

Market Background: The "Calm" After Trade Shocks and Subtle Shifts in Macro Policy

In April 2025, a large and more-than-expected U.S. tariff announcement triggered synchronized declines in global asset prices, and volatility in international financial markets rose sharply. In the following months, as the most extreme risks of a global retaliatory trade war receded, market volatility gradually fell back to long-term averages or even below. The RBA, however, noted that the international outlook remains highly uncertain, particularly concerns about fiscal sustainability in some advanced economies, as well as the lagged effects of tariff increases on U.S. domestic prices and economic activity.

Meanwhile, credit conditions in advanced economies have gradually eased over the past year. After absorbing the earlier tightening cycle and cost pressures, households and businesses have generally shown resilience in their balance sheets. Systemically important banks are well capitalized and capable of absorbing losses even if an economic downturn leads to rising non-performing loans. However, this overall resilience does not mean there are no cracks: some highly indebted, low-income households and businesses continue to experience financial stress.

Current Capital Flows: Surface Strength in Equity and Bond Markets, and a Lull in Private Markets

In terms of market performance, capital has returned to chasing risk assets after the setback in April. Global equities not only recovered all of their declines, but some countries even reached record highs. Notably, the top ten companies in the S&P 500 index (most of which are technology firms) now account for more than 40% of the index's total market capitalization, with market concentration at historical highs. Meanwhile, the global equity risk premium remains at historically low levels, meaning the excess compensation investors receive for bearing equity risk is increasingly thin.

In credit markets, corporate bond spreads widened at one point in April but have since fallen to the low end of their historical range. Such accommodative financing conditions have allowed most companies to refinance in a timely manner, and U.S. high-yield bond issuance has rebounded strongly after a brief pause in April. The RBA, however, specifically cautioned that roughly one-fifth of corporate debt in Europe and the United States will mature within the next two years, and some borrowers may need to roll over longer-term debt at significantly higher interest rates.It is worth noting that the pace of capital flows in private markets is changing. After a period of rapid growth, private credit assets under management slowed markedly in 2024, with new fundraising declining and the industry's "dry powder" (committed but uninvested capital) shrinking. At the same time, global private equity funds are facing headwinds on the exit front, with the time taken to return capital to investors lengthening—and such returned capital often serves as an important source of funding for new vintages of private funds.

Another undercurrent is the accumulation of leverage. Since early 2020, the total notional exposure of US hedge funds has grown at an average annual rate of about 13%, reaching $34 trillion by April 2025—a pace exceeding that of US bank assets. Their borrowing from repo markets and prime brokers has risen to record levels. This leveraged growth has significantly increased the risk that non-bank financial institutions may be forced to sell assets simultaneously when markets come under stress.

Investment Logic Analysis: Several Structural Supports Behind the Optimism

Why are funds still willing to buy risky assets in an environment of extremely low risk premiums and extremely high market concentration? The RBA report offers several observations, which actually reveal the underlying logic on which long-term asset allocation depends.

First, expectations of policy easing provide an anchor for pricing. Over the past year, credit conditions in major global economies have tended to ease, while markets widely expect policy rates to continue to decline. Such expectations directly lower discount rates, enhancing the relative appeal of equity assets and allowing corporate financing activities to proceed smoothly.

Second, corporate earnings have beaten expectations. Despite the impact of tariffs on some sectors, overall earnings expectations have rebounded after a brief downward revision. Technology companies in particular have continued to support market confidence through their earnings growth and cash flow performance. This micro-level resilience makes investors willing to temporarily overlook multiple macro risks.

Third, the "search for yield" persists amid global savings glut and low interest rates. With limited returns on safe assets, pension funds, insurers, and sovereign wealth funds continue to shift toward higher-yielding assets, including private credit, infrastructure, and top-tier technology equities. This explains why capital remains willing to stay in the market even as risk premiums are compressed.

Fourth, the rise of non-bank financial institutions has changed the mechanism of capital transmission. Money market funds, open-end funds, and hedge funds all have assets under management near or at historical peaks. The marginal pricing power of institutional capital has become stronger, but this also makes asset prices more vulnerable to reversals in capital flows. For long-term investors, this is both a thematic opportunity and a potential source of portfolio volatility.

Risk Factors: Five Dimensions That Could Threaten Systemic Stability

Although market sentiment has recovered quickly, the risks facing the global financial system continue to transmit along multiple dimensions.Trade and supply chain risks. Although a full-scale trade war has been avoided for now, more substantial trade disruptions could remain a tail risk for the corporate sector, potentially exerting a greater-than-expected impact on earnings and debt-servicing capacity in sectors with high trade exposure, such as consumer, energy, and industrials.

Fiscal sustainability risks. High debt levels in advanced economies have made markets more sensitive to sovereign creditworthiness. If bond markets demand higher term premiums, global risk-free rates would be repriced, thereby spilling over into all risk assets.

Risk amplification from non-bank institutions. Open-end funds, money market funds, and hedge funds hold large leveraged and maturity-mismatched positions. A sudden surge in market volatility could force these institutions to delever in a disorderly manner, amplifying the fall in asset prices. Meanwhile, the opaque information environment, data gaps, and the lack of a full credit cycle experience in private credit could make it a weak link.

Delayed manifestation of corporate credit risk. In a low-interest-rate environment, lower-rated companies have been able to postpone restructuring, but default rates remain relatively high. If an economic slowdown or interest rates not falling as much as expected coincides with the peak of refinancing over the next two years, the risk of a concentrated outbreak of corporate credit events would rise significantly.

Cross-border risks and geopolitics. Armed conflict, cyberattacks, and regulatory divergence are becoming new variables in financial stability. The physical risks and transition risks of climate change are also gradually transmitting to the macro level, including insurance, asset valuations, and local government debt.

For long-term investors, these risks are not isolated from one another. A modest shock could quickly evolve into systemic volatility through liquidity spirals or sovereign credit chains—which is precisely what needs to be guarded against rigorously in the current low-risk-premium environment.Third, the maturation and differentiation of private markets will test institutions’ management capabilities. The wave of low interest rates and liquidity that drove the expansion of private credit and equity over the past decade is receding. Going forward, top-tier managers will rely more on active exits and post-investment management to generate returns, while ordinary investors may need to demand higher liquidity premiums and greater transparency in their private market allocations.

Fourth, market concentration itself may become a long-term theme. The rising weight of technology giants in indices means that simple index investing strategies are becoming increasingly concentrated. Institutional investors may need to revisit their control of factor exposures—for example, by adopting equal-weight or fundamental-weight strategies, or by increasing allocations to diversified small-cap segments—to reduce the volatility arising from any single factor.

Finally, climate change and digital transformation are reshaping the underlying economic structure. In the short term, they remain nominally “non-financial factors”; but over the long term, these factors are likely to appear on financial institutions’ balance sheets in the form of credit losses, asset impairments, or capital requirements. If long-term capital can explicitly incorporate these externalities into valuation models, risk-adjusted returns over the next decade could diverge significantly.

Overall, the global macro-financial environment in October 2025 is poised on a delicate balance: markets have absorbed shocks with speed, but the slowly accumulating leverage, mismatches, and uncertainties have not truly disappeared. Rational investors should view the current low risk premia as a window for “cautious recalibration,” rather than merely as confirmation of trend continuation. For institutions with large asset sizes and long durations, building resilience to adversity during favorable times may be the real lesson of this macro-financial cycle.
