The Market Rally Faces a Fresh Test in Q4 on Resurgent Geopolitical Volatility

John Mullane

The third quarter brought renewed volatility across global financial markets as the breakdown in the US-Iran ceasefire triggered a sharp rebound in commodity prices, fuelling concerns that inflationary pressures would linger. A global recalibration of interest rate expectations followed which, combined with increased bond issuance and concerns on government borrowing levels, drove yields higher across the curve. These factors also contributed to fluctuations in currency markets. Despite these headwinds, global equities continued to grind higher, supported by resilient economic growth and strong corporate earnings.

 

Given the strong fundamental backdrop, we remain constructive on risk assets into the final quarter of 2026. The compression in valuation multiples has improved the attractiveness of equities, however, higher bond yields are providing increased competition for investor capital, making the delivery of strong corporate earnings, particularly within tech, increasingly important in supporting further market gains during Q4. This will be particularly relevant in the US, where investment in artificial intelligence remains an important driver of both economic activity and corporate earnings growth. The quarter will also see voters go to the polls in the US mid-terms, an event that has been associated with heightened volatility given its implications for the policy outlook. However, markets have historically responded favourably once the outcome of the election becomes clear and uncertainty begins to recede.

 

Line chart titled “Faster relative earnings momentum on offer in emerging markets” showing relative 12‑month forward earnings per share from 2016 to 2026 (index, Dec 2015 = 100). Two lines are plotted. The gold line, representing U.S./Other developed markets, trends steadily higher from around 100 in 2016 to approximately 175 by 2026, despite some fluctuations. The blue line, representing Emerging markets/Developed markets, rises slightly above 100 until 2018, then declines, reaching a low of about 65 in 2025 before recovering sharply to just above 100 in 2026. The chart highlights that while earnings expectations for U.S. and other developed markets have strengthened consistently over the past decade, emerging markets have underperformed for several years but are now showing a notable rebound in relative earnings momentum.

Political developments will also remain a key consideration in Europe, where ongoing French budget negotiations have heightened concerns around the country’s fiscal position. Whilst a prolonged deadlock could contribute to further volatility in European bond markets, the impact on equities is likely to be more limited, with increased investment in infrastructure and defence helping to underpin a significant improvement in corporate earnings growth. Emerging markets should also continue to offer attractive opportunities, supported by improving relative earnings momentum, particularly in Asia, where strong global demand for semiconductors and advanced electronics is boosting export growth and broader economic activity.

 

In fixed income, higher yields have significantly improved the range of income opportunities available across the asset class. However, persistent inflation and elevated government borrowings are likely to create increasingly divergent outcomes across regions and sectors, reinforcing the importance of careful credit selection and active duration management. Elsewhere, Infrastructure remains a preferred asset class, supported by structural investment themes including electrification and energy security, whilst gold continues to offer valuable diversification against geopolitical and fiscal uncertainty.

 

Bar chart titled “A significant portion of the bond market now offers attractive yields” showing the share of fixed income assets yielding over 4% from 2000 to 2026. The chart uses stacked vertical bars to display the percentage of the bond market yielding more than 4%, broken down into five sectors: Core Government bonds, US Government-related bonds, US Mortgage-Backed Securities and Commercial Mortgage-Backed Securities (MBS & CMBS), Global Investment Grade Credit, and Global High Yield & Emerging Markets debt. Between 2000 and 2008, roughly 55% to 100% of fixed income assets yielded above 4%, with contributions from all bond sectors. Following the global financial crisis, the proportion declined sharply. From around 2011 to 2020, the share of assets yielding above 4% remained very low, generally between 5% and 20%, with most of the available yield coming from Global High Yield and Emerging Markets debt. From 2021 onward, the proportion increased significantly, reaching approximately 80% to 85% by 2023–2026. The improvement is broad-based across fixed income sectors, including Core Government bonds, Investment Grade Credit, mortgage-backed securities, and High Yield debt. The chart illustrates how rising interest rates have restored attractive income opportunities across much of the global bond market after more than a decade of relatively low yields.

Looking ahead, whilst resilient economic fundamentals and strong corporate earnings continue to support markets, geopolitical developments are likely to drive heightened volatility across and within asset classes. As a result, maintaining a diversified portfolio that is actively managed will be critical in navigating the evolving market backdrop and capitalising on emerging opportunities.
