One economic indicator is the US Treasury 5s10s curve or 5s10s spread, which is simply the difference between the 10-year US Treasury yield and the 5-year US Treasury yield. It is also referred to as 10s52s, 5s/10s, 10-5 yield spread and so on, but 5s10s is the most common name. There are other yield curve spreads as well, including the most popular 2s10s spread.

Below is a chart of the 5s10s through time.

How is the 5s10s calculated?

We can see how the US Treasury 5s10s spread is calculated below, by simply subtracting the 5-year yield (red line) from the 10-year yield (blue line).

What is the significance of the 5s10s?

Historically, steep yield curves (indicated by a high 5s10s reading) are often followed by strong economic and financial market performance, while flat yield curves (indicated by low 5s10s readings) are followed by weaker performance.

Sometimes the yield curve flattens so much that it “inverts” and shorter-term rates are higher than longer-term rates (and the 5s10s reading goes negative). An “inverted yield curve” is typically seen as a warning sign as inverted yield curves are often followed by recessions. The gray bars in the above charts indicate recessions.

The 5s10s seems to be one of the worst yield curve measures, in terms of predicting recessions. This measure did not invert prior to the 2020 recession (although maybe we can forgive it for not predicting a pandemic!) and it also inverted several times in the 1980s and 1990s without any immediate recession. For a brief summary of which yield curve measures have the best track record of “predicting” recessions, read this post of whether the yield curve predicts recessions.

How to track the 5s10s

You can find the US Treasury 5s10s on many websites. My favorite website to track the 5s10s is FRED (Federal Reserve Economic Data), which is published by the Federal Reserve Bank of St. Louis. The first chart (above) can also be found here.

Other yield curve spreads

There are many other yield curve spreads that market participants and policymakers monitor, such as the 2s10s, the 3-month 10-year spread, and many others. For an up-to-date look at other yield curve spreads, see our yield curve spread chart page.
