Could Bad News Mark the Top in Yields?

One of the more interesting developments in the bond market last week, in our view, had less to do with the news itself and more to do with how the markets reacted to it.

My colleagues and I often talk about “news failures” or “news reversals.” These occur when a market receives a piece of information that should, at least on the surface, push prices decisively in one direction, but then either fails to respond as expected or initially moves the way everyone expects before abruptly reversing course. These types of reactions can be important because markets also trade on expectations, positioning, and supply and demand, not simply whether a headline is fundamentally good or bad. When seemingly bearish news can no longer push a market lower, or bullish news can no longer push it higher, it is worth paying attention as it often signals that the news has already been discounted, positioning has become too one-sided, or that the underlying trend is beginning to lose momentum.

We witnessed a pretty compelling example of that dynamic in the Treasury market last week. Following a firmer-than-expected September Consumer Price Index (CPI) report, the initial reaction was exactly as one would expect. The 10-year Treasury yield jumped sharply immediately following the release as investors digested the prospect that persistent inflation would keep the Federal Reserve (Fed) more restrictive. But then something interesting happened. Yields stopped rising. After the initial spike, the move quickly reversed, and yields started moving lower. Similar reversals developed across much of the Treasury curve. That is notable because the inflation news itself had not suddenly become less concerning. What changed was the market's willingness to continue selling bonds on bearish news. That distinction matters.

After a sharp and steady rise in yields since the middle of the summer, the Treasury market has recently started showing signs of being stretched. From a technical perspective, bonds had become deeply oversold (yields overbought). At the same time, sentiment toward bonds had deteriorated to unusually pessimistic levels and positioning had become heavily skewed toward higher yields. Measures such as Market Vane have recently reflected some of the most bearish bond sentiment in years, while speculative positioning across the Treasury curve has remained heavily short, as highlighted in the “U.S. Treasury Positioning Has Remained Heavily Short” chart. Put it all together and you have many of the ingredients for a tactical reversal in trend. That does not necessarily mean the peak in yields is in, but when a market stops responding to information the way it “should,” it is often an early sign that something beneath the surface has changed or is at least beginning to.

That is why we will be closely monitoring the bond market here at LPL Research. Follow-through will be key. A sustained move in the 10-year Treasury yield below the psychological 5.00% area would add credibility to the idea that a more meaningful tactical change in trend is developing. Conversely, a move back through the recent yield highs around 5.36% would suggest last week’s reversal was just a temporary reprieve within the broader trend toward higher yields. For now, we watch and wait, but after months of relentless upside pressure in bond yields, the fact that bad news could no longer make them go up is a clear sign that the trend is finally beginning to lose momentum.
