What is the yield curve, and why did short-term and long-term Treasury yields move in

opposite directions after Wednesday's Fed decision? The yield curve is a simple line chart. It plots the yields (the interest rates) on U.S. government debt from a few months out to 30 years, so you can see at a glance what lenders ask to tie up money for short versus long stretches. Most of the time the line slopes upward, because lending for 10 or 30 years carries more uncertainty than lending for a few months, and investors want extra pay for that.

On Oct. 28 the Fed held its benchmark rate at 3.75% to 4% in a 10-2 vote, with two members preferring a quarter-point hike. The 2-year Treasury yield, which tends to follow expectations for the Fed's short-term rate, slipped 0.004 percentage point to 4.731%, while the 10-year yield rose 0.052 point to 5.044%, its biggest gain since Sept. 28. When long yields rise relative to short ones, the curve gets steeper, and on Wednesday the 10-year finished about 0.31 percentage point above the 2-year. A steepening curve is often read as the market expecting stronger growth, higher inflation or higher rates down the road. When short yields climb above long yields, the curve is called "inverted," which many people watch as a warning sign, though Fed researchers caution that it isn't a reliable recession forecast on its own.

The yield curve doesn't tell anyone what stocks or bonds will do next. It's a quick picture of how the market is pricing time and risk, and it's worth knowing when you see "the curve steepened" in the headlines. What questions do you have about yields or the yield curve? There are no silly questions here, so ask away below.
