Global markets have been turbulent this year amid escalating tariff tensions and concerns around inflation and growth. Risk assets, particularly equities, have experienced sharp declines as investors grapple with policy uncertainty. Even traditionally stable developed bond markets – which have historically offered shelter during volatile periods – have exhibited unexpected price swings. We’ve seen an aggressive sell-off in longer-dated bonds, reflecting deeper structural shifts and changing fiscal dynamics in developed economies.
April vividly illustrated this unusual market behaviour as traditional correlations expected during risk-off episodes broke down. Equities fell sharply, yet the US dollar weakened against the euro, and the 10-year US Treasury yield rose, clearly diverging from typical risk-off dynamics.
This complex backdrop presents distinct challenges for fixed income investors, with sentiment globally having taken a knock. Conservative investors – especially those holding substantial positions in dollar cash – may instinctively favour caution, choosing to remain on the sidelines until clearer signals emerge. However, this perceived safety could mask hidden risks.
Tariff measures introduced by US President Trump have injected inflationary pressures into global markets. Although some of these tariffs – including key ones involving China – have recently been reduced as trade negotiations resume, several remain in effect. These tariffs are effectively inflationary – raising prices of imported goods – but crucially, their indirect impacts dampen economic growth.
We expect short-term inflationary effects to give way to substantial growth challenges. However, the outlook for the US could be different than many other countries impacted by tariffs. Our current assessment suggests the US faces stagflation risks – higher inflation followed by slower growth. Conversely, other countries and regions, including Europe, the UK and New Zealand, might experience deflationary pressures due to currency strength and exposure to reduced global trade.
Market dynamics are shifting as global economies enter late-cycle territory and policymakers grapple with how best to respond to tariffs. With countries and regions diverging in interest rate responses and economic outlooks, diversification across markets is more important than ever.

Market expectations have moved significantly more dovish. The probability of rates being cut further in 2025 in the US (implied by the options markets) has increased from 50% to 80%.
Markets are pricing in more interest rate cuts, leaving cash investors exposed to both eroding purchasing power and the likelihood of much lower yields when reinvesting. Locking in current attractive yields through diversified fixed income instruments mitigates these risks, helping to secure a stable income stream.
While the US path of interest rate cuts will likely be shallow due to persistent inflationary pressures, we anticipate more aggressive interest rate cuts in markets like the UK, Canada and New Zealand. These three countries currently have relatively restrictive monetary policies, positioning them for deeper rate reductions than markets currently anticipate. Our proactive stance in these regions aims to lock in yields at attractive levels, which could also provide potential capital gains as interest rates decline.
For instance, we have reduced the Ninety One Global Diversified Income Fund ’s exposure to longer-duration US and European bonds, redirecting capital to shorter-duration and higher-yielding positions in Canada, New Zealand and the UK. Such targeted moves illustrate our responsiveness to shifting market conditions and our commitment to safeguarding investor capital while enhancing yield.
Our cautious stance extends to credit markets, where we maintain a strong preference for shorter-duration high-quality, investment-grade corporate bonds. This selective approach has minimised the portfolio's exposure to recent volatility in credit spreads. We distinguish between temporary market dislocations and deeper systemic issues through rigorous analysis, choosing assets resilient to economic stress. Additionally, structured credit products like mortgage-backed securities (MBSs) and collateralised loan obligations (CLOs) further diversify and enhance the portfolio's yield, offering stability beyond traditional corporate paper.
Currency strategy is another important component of our approach. While predominantly holding US dollars, we dynamically manage currency exposure – for example, recently taking positions in the yen to mitigate volatility and strengthen capital protection. This flexibility enables us to swiftly adjust to changing market conditions, ensuring resilience during turbulent periods.
Offering a yield of around 4.9%,1 the Ninety One Global Diversified Income Fund embodies our balanced investment philosophy. We focus on robust capital preservation and yield enhancement through prudent duration management, targeted credit exposure and tactical geographic diversification.
Ultimately, our fund aims to provide conservative investors with an attractive alternative to holding dollar cash, carefully balancing risk and return. Amid ongoing market uncertainty, prudent diversification, flexibility and active management remain crucial in today's challenging global fixed income landscape.
