Key Points

What it is

Geopolitical instability, rising government debt, and accelerating AI adoption are converging to help shape market sentiment and asset allocation.

Why it matters

Investors are navigating a landscape marked by structural shifts, valuation pressure, and uneven global growth, all of which demand greater selectivity and resilience.

Where it's going

We remain focused on resilience and selectivity, favoring non-U.S. equities and infrastructure as markets navigate uncertainty and evolving growth drivers.

In today's dynamic financial landscape, three major themes interplay to shape market movements: Geopolitics, Debt & Deficits, and The Tech Supercycle. These forces are intricately connected, influencing investor sentiment and global economic trends.

 

We are navigating an environment characterized by a multipolar world. Territorial disputes and fears surrounding nuclear rearmament persist, presenting significant challenges to global stability. Despite the desire of the U.S. to reduce its international engagements, it remains the principal military power capable of mitigating global disorder. This is evident through its support for Ukraine, facilitating a ceasefire between India and Pakistan, and its recent endeavors to negotiate with Iran to abandon its nuclear ambitions.

 

The uncertainty creates powerful investment implications. It is likely to lead to increased spending on military capabilities around the globe. In addition, the risk premium in commodity markets is likely to persist and investors should be prepared for potential supply disruptions.

 

Debt & Deficits: The last few years have witnessed an uptrend in government debt worldwide, primarily driven by fiscal support measures implemented in response to the COVID pandemic. Over the next five years, trends in fiscal consolidation are poised to diverge notably. The U.S. exemplifies a nation postponing the balancing of its budget until later in the decade, sustaining a substantial deficit of around 5-7% to bolster its economy. This increase in debt levels is anticipated to limit funding availability for the corporate sector, potentially burdening it with higher funding costs. Other parts in the developed world are on a more decisive path of fiscal consolidation, which should support their local government bonds as safe havens for investors.

 

The Tech Supercycle: Artificial Intelligence (AI) has transitioned from being a mere tool to a foundational layer across numerous sectors. This transformation is reinforced by the rapid expansion of digital infrastructure, including 5G, cloud computing, and the establishment of additional data centers (global data center demand is expected to grow by a 15% CAGR (Compounded Annual Growth Rate) to 152 gigawatts in 2030 – Royal Bank of Canada). These trends appear sustainable and robust, exhibiting resilience against short-term economic volatility.

 

The recent earnings season highlighted firms' confidence in AI-driven growth and resilient cloud performance. Companies are aggressively pursuing capital returns, reflecting their optimism in leveraging technological advancements to drive future profitability.

 

Conclusion: These themes are interconnected, and markets engage with and are propelled by the forces they generate. These forces significantly impact our research perspective through which investment riskiness is assessed, prioritizing resilience and adaptability in volatile environments.

TECH EARNINGS SUPPORT

Megacap tech’s advancement in innovation is expected to drive continued earnings growth dominance.

Interest Rates

 

How have U.S. Treasury auction results been? While a handful of U.S. Treasury auction results drew attention in April, we haven’t seen a widespread shift in demand across the curve in recent auctions. in particular have seen solid demand as net supply is currently negative. Precisely determining “foreign demand” in real time is quite difficult, but, on the whole, investor demand doesn’t appear to have shifted as definitively as some press reports may lead you to believe.

 

Are there any signs that investors are changing their allocations to cash assets like MMFs (Money Market Funds)? MMF assets at the industry level have been growing this year, albeit at a slower pace than the strong run up seen during the prior 2 years. Instead of a shift in cash allocations, which largely held steady even during April of this year, perhaps we’re seeing cash allocations being maintained around all-time highs as measured by industry assets under management.

 

Are there potential policy changes on the horizon that you’re watching? Details around the implementation of central clearing of U.S. Treasuries, potential design changes of the Standing Repo Facility, as well as potential changes to the Supplementary Leverage Ratio.

U.S. BILL NET SUPPLY HAS BEEN NEGATIVE RECENTLY

  • Despite some attention-grabbing Treasury auctions in April, overall demand — especially for T-Bills — remains solid, with no broad signs of investor fatigue.

  • Cash allocations like money market funds continue to grow, though more gradually, suggesting investors are maintaining high cash levels rather than reallocating.

  • We’re closely monitoring potential policy shifts that could reshape Treasury market dynamics such as central clearing, repo facility tweaks, and leverage ratio changes.

 

 

Credit Markets

 

High yield (HY) saw solid performance last month with the strongest monthly spread performance since 2023. Despite some volatility in the rates market, HY spread tightening offset negative impacts from duration, resulting in attractive absolute returns. As trade tensions eased, capital markets activity resumed. In May, $32 billion of HY gross issuance represented substantial increases in monthly volume from the tariff-induced market slowdown in April.

 

While HY supply was elevated last month, technicals continued to be favorable with HY producing its 5th consecutive supply deficit year-to-date due to continued strong organic inflows. Year-to-date, Calls ($55.5bn), Tenders ($11.3bn), and Maturities ($21.3bn) totaling $88.1bn compares to $105.8bn of gross new-issuance year-to-date. Meanwhile, coupon reinvestment ($28.5bn, assumes 75% reinvestment rate) and retail inflows (+$1.8bn) total $30.3bn. With Fallen Angels exceeding by $10.8bn, the high-yield bond market has produced a supply deficit of -$1.4bn in 2025 year-to-date following four consecutive years of supply deficits (-$496bn aggregated).

Equities

 

Across 2025 year-to-date – global equities are up 7% with notable separation between U.S. equities (+2%) and strong gains (in dollar terms) in both non-U.S. developed (+18%) and emerging market equities (+12%). U.S. equities have gained back a little ground over the last month with some help from the resurgence in megacap tech. Cyclical areas of the market performed better than defensive areas over this stretch. Non-U.S. equity returns continue to benefit from decent performance in local currency terms plus currency impacts when in dollar terms.

 

The S&P 500 widened back out to a little under 22x, above 2024 year end and not far below February’s peak, reflecting reduced fear of meaningful disruption from trade policy. There continues to be a bifurcation between Megacap tech and non-megacap tech earnings contributions. Some of the potential tariff headwinds that are not embedded in company guidance skews risk to the downside in earnings expectations. Although the tech rally could continue to support U.S. equities, we do not believe it is a good environment to take a sizable position in either direction. Instead, we prefer non-U.S. developed equities within our tactical equity allocation.

  • Although the tech rally could continue to support the U.S. market, we do not believe it is a good environment to take a sizable position in either direction.

 

 

Real Assets

 

Listed infrastructure has long been a favored option of global investors due to the sector’s high barriers-to-entry, predictable, inflation-linked cash flows, and equity-like returns with lower volatility. These characteristics have led to premium valuations for the sector, as listed infrastructure historically trades at a 9% premium to global equities on an EV/EBITDA basis.

 

Starting in 2022, the global risk-free rate began an upward trend driven by central banks need to combat inflationary pressures coming out of the pandemic. Global rates have stayed at these higher levels and this more normalized interest rate environment has pushed infrastructure multiples to the lower end of their historic trading range.

 

A supportive fundamental outlook for infrastructure has drawn investor interest, especially with the backdrop of higher global power demand driven by data centers, energy independence and security, and onshoring and decarbonization of industrial processes. These growth drivers, along with the sector’s essential service nature and historically low relative valuations make the potential for investment in the sector particularly compelling.
