In the United States, preliminary data for the first quarter indicates unit labour costs rose by 5.7%, surpassing the expected increase of 5.1%. The previous quarter’s figure was revised from 2.2% to 2.0%.

Productivity saw a preliminary decline of 0.8%, compared to the anticipated 0.7% decrease. The prior quarter’s productivity figures were adjusted from a 1.5% increase to a 1.7% increase.

Interpreting Inflationary Pressures

These figures suggest potential inflationary pressures, but interpreting them can be challenging due to their variability and the fact that they often reflect past trends.

The earlier figures reveal a faster increase in costs per unit of output, meaning that businesses are paying more in wages and benefits for each item or service produced. When unit labour costs rise unexpectedly, as they have here, it reflects mounting wage pressures not offset by corresponding improvements in efficiency. In this context, the drop in productivity further compounds the issue—fewer goods or services are being produced for each hour worked, just as the cost of that hour becomes more expensive.

For those of us assessing rates and volatility with a forward view, the concern lies not just in the numbers themselves but in what they imply for policy positioning and market reaction. Powell and colleagues at the central bank prioritise inflation expectations over time, and when cost pressures emerge alongside declining productivity, the risk of persistent upward pressure on prices rises. This type of development can make central bankers more hesitant to loosen policy unless they see definitive signs of disinflation taking hold.

What throws an added layer into the mix is how revisions have come in. The upward shift for previous-quarter productivity, albeit slight, adds some complexity to how we weigh the trend. It doesn’t negate the current drop, but it softens the broader signal just enough to introduce a measure of doubt over whether this is a temporary reversal or part of a pattern.

Impact On Markets And Policy

In recent weeks, we have observed short-term interest rate pricing react with heightened sensitivity to data that speaks to either wage strength or productivity shifts. That’s because these indicators feed directly into the inflation picture and, by extension, central bank resolve. Markets hinging on rate path clarity tend to pick up on these inputs with outsized moves, especially in quiet stretches where data is sparse.

For our activity in options and futures, this means terminal rate expectations may show bursts of repricing around labour market and cost metrics. It’s not just a question of where rates are going, but how quickly—and more importantly, how confident the market is in any projected pathway. Waning productivity alongside unanchored wage growth is not a combination that supports rate declines.

Further forward, yields may remain stubbornly sticky if future prints follow a similar path. We’re continuing to watch how implied volatilities skew across maturities, as there’s a strong likelihood that downside bias in rates repricing could be tested if these trends persist. We’ll also remain flexible around Fed-related event risk, since the committee places heavy emphasis on productivity and cost-efficiency metrics when outlining its stance.

We see this set of data as another push against early optimism over rapid disinflation. It reminds us to keep a steady focus on real economy inputs, not just headline readings. Traders should ensure positioning reflects potential for stickier inflation via labour and output trends, especially as expectations around mid-year policy shifts get further established.
