Two markets, two narratives: the divergence between fixed income and equities

The current situation in financial markets is characterized by an unusual divergence: while equities maintain a clearly optimistic tone, supported by very solid corporate results, sovereign bonds convey a message of growing unease. This disconnect is not simply a one-off anomaly, but rather the expression of two distinct interpretations of macroeconomic and financial developments in the short and medium term. Historically, both markets tend to converge, but in the current environment, there are reasons why they may remain divergent for some time.
On the one hand, the bond market is reacting to a combination of factors that point toward a more complex scenario. The main catalyst in the short term is inflation, which has rebounded, driven by rising energy costs stemming from the conflict between the United States and Iran. This energy shock not only raises prices but also introduces uncertainty about its duration, which is particularly relevant for monetary policy expectations. Central banks have not yet made a move, but market expectations are pricing in upcoming interest rate hikes in both Europe and the United States. Added to this is an even more worrying underlying factor: the high level of public debt, particularly in the United States, where the cost of servicing the debt has reached historically high levels (1.3 trillion dollars), becoming a growing structural burden, and the second largest after social security.
This environment is clearly reflected in the evolution of long-term interest rates. Yields on the 10-year and 30-year US Treasury bonds stand at 4.60% and 5.13% respectively, levels that have only been exceeded twice in the last two decades, precisely during the fall of 2023, when the benchmark US rate was at record highs, and with the Fed still maintaining a restrictive tone with its famous phrase «high rates for longer.» This not only implies a tightening of financial conditions for businesses and households, but also a warning sign regarding expectations for inflation, growth, and fiscal sustainability. The bond market is therefore pricing in a scenario where inflation could remain elevated for longer than initially anticipated, forcing central banks to maintain restrictive policies in a context of high debt. This combination is particularly troubling because it limits the policymakers’ room for maneuver and increases the risk of economic policy errors, especially in Europe, where it seems contradictory to consider interest rate hikes at a time when the European economy is showing clear signs of weakness.
In contrast to this cautious message from fixed income, equities are performing remarkably well. The main argument supporting this strength is the evolution of corporate profits, which have generally surprised on the upside. Earnings growth has been much higher than expected, with a high percentage of companies exceeding expectations in both revenue and earnings per share. This dynamism has been particularly visible in the technology sector, which continues to act as a driving force in the stock market.
The explanation behind this resilience lies largely in the emergence of artificial intelligence as a structural engine of growth. Unlike previous cycles, where expectations regarding technological potential were more speculative, in the current case, the revenue growth associated with these technologies is evident, and their adoption by both companies and society at large is not a future possibility or an expectation, but rather a reality.
Investment in artificial intelligence is massive and cross-cutting, with profound implications for productivity, business models, and profit margins. From this perspective, although equity markets are not ignoring macroeconomic risks, they seem to prioritize a long-term narrative in which technology offsets, at least partially, short-term headwinds.
However, this apparent disconnect raises a fundamental question: can both narratives be sustained simultaneously? The answer is that, although they may coexist in the short term, the divergence will tend to resolve itself in the medium term. The key lies in the impact that high interest rates have on equity valuations. As debt yields increase, the cost of capital rises, and the discount rate applied to future cash flows is higher, putting downward pressure on valuation multiples. This effect is especially relevant for companies with long-term growth expectations, where a significant portion of their value depends on future earnings.
Furthermore, although many large technology companies have demonstrated enormous cash generation capacity so far, the massive amount of capital being invested means that, by 2027, it is estimated that virtually all of the cash generated will be allocated to capital expenditures (capex), which is why some of these companies are beginning to increase their debt levels. If this process continues in a high-interest-rate environment, the impact on their earnings could become more pronounced, reducing equities’ ability to remain unaffected by the warning signals issued by fixed income.
Another element reinforcing the idea of a disconnect is the evolution of corporate credit. Despite rising sovereign debt yields and macroeconomic concerns, credit spreads remain very narrow, near historic lows. This suggests that the market continues to price in a benign scenario in terms of defaults and corporate stability. However, this view is difficult to reconcile with the more pessimistic interpretation of public debt, especially considering that a high-interest-rate environment and inflationary pressure could worsen economic conditions and increase credit risk.
In conclusion, we can say that the key to understanding the current divergence lies in expectations. Equities seem to be pricing in a scenario in which the energy shock is transitory and inflation will moderate relatively quickly, allowing for a normalization of financial conditions. Conversely, fixed income anticipates the possibility that this shock could have more persistent effects, forcing banks to maintain high interest rates for longer and generating additional tensions in highly indebted economies. The resolution of this divergence will therefore depend on how these factors evolve. If inflation moderates and geopolitical tensions ease, fixed income could experience a relaxation that would validate, at least partially, the optimism of equities. On the other hand, if inflation remains high and necessitates a prolonged tightening of monetary policy, pressure on stock valuations will increase, and equities will have to adjust their expectations.
