Having increased significantly, bond volatility has de-coupled from the stable volatility of equities since Mach 2023. In fact, the ratio of the two has never been bigger since 2003. What is the cause of the de-coupling of equity volatility from bond volatility; and, is it permanent?

Intuitively, the extraordinary volatility of bonds makes sense because it is fuelled by inflation, whose predictability has been limited during the aforementioned period. On the other side the countermeasures taken by central banks, which would not always match market expectations, also had an impact. In addition, the incident surrounding Silicon Valley Bank in March changed interest rate expectations and caused extreme levels of volatility.

Equity volatility, on the other hand, remains at the moderate lower end of its range and does not correspond to what one would expect in an environment perceived as uncertain.

Company earnings remain high

One reason for the current stability of equities can be found in profit margins and the earnings situation as a whole. In the USA, profit margins have moved significantly away from their peak (13.1%) at the end of the COVID pandemic. Nevertheless they have maintained their long-term upward trend at 10.0% and remain high. High company earnings are dampening volatility.

In addition, the US reporting season has shown a jump in positive earnings surprises for the first time in about 1.5 years. The negative surprises have fallen by roughly the same degree. Although expectations were already cut in the run-up, there is still no reason for an increase in volatility.

In the medium term, a narrowing of profit margins may be in the offing as the Fed seeks to take pressure off the depleted labour market. However, layoffs on a larger scale will take place if, and only if, the earnings situation in the corporate sector turns gloomy. While company profits are not a directly adjustable variable for the Fed, their reduction would be accepted.

Indicators suggest imminent recession

A noticeable recession in the USA represents the most significant risk for the equity markets. Recessions have been predicted in the past, but their timing and extent cannot be determined in advance from economic data. The Federal Reserve Bank of Cleveland calculates a probability model from the structure of the US yield curve. Its inversion has been a reliable harbinger of a recession, i.e. a situation where one receives more interest for a short investment than for a long-term one, which documents great uncertainty.

At 75.5%, the result is the highest since 1990, with the timing set at April 2024. At the same time, it is important to remember that this model is a purely mechanistic one and may not fully account for the situation. This refers to the scenario relating to the pandemic in which the overall economy was deliberately shut down, the associated massive shift in demand from services to goods, the government transfer payments, the global logistical bottlenecks, etc. These are factors that have not occurred in combination before.

The leading indicator of the Conference Board also clearly suggests a recession. Interestingly, here, an indicator for the actual state of the economy is calculated in parallel, which is inconspicuous. This means: a stable picture of the US economy today – and with it, low equity volatility – but potential problems in the future.

Positions in the market

A remaining reason for the low volatility of equities is the positioning of the market, as measured by the number of speculative futures positions. This number is decidedly low. Its trend is comparable to the Purchasing Managers’ index (PMI) for the industrial sector, the leading indicator for economic activity in the US industry, which is under pressure. Now, it is easier for a sceptical market to process unpleasant news because much is already priced in. In addition, the extent to which the market can now become even shorter is limited.

What indicators can you track to identify stress in the market? We offer three:

  • the price ratio of defensive and cyclical equity sectors
  • the US dollar index, which often gains strength in a stressed environment
  • the BBB spread (risk premium for bonds with a “BBB” rating, corresponding to just investment grade, i.e. a good to very good credit rating) as a measure of credit risk

The last chart shows these indicators (USA values). Their time series shows a mixed picture. Defensive equities have recently outperformed cyclical equity sectors; the US dollar index, on the other hand, shows weakness; and the BBB spread has moved sideways.


The current comparatively low volatility of equities can be well argued. Bond volatility will remain high, as inflation is stabilising, but surprises can pop up at any time and affect the data.
