What drove the rise in long-term Treasury yields?
Core argument: The authors attribute the rise in Treasury yields in the second half of 2023 primarily to higher term premiums, fueled by quantitative tightening, greater Treasury issuance, and heightened uncertainty about the economic outlook.
Our analysis suggests that the rise in yields [in the second half of 2023] was primarily driven by an increase in term premiums, fueled by the combination of quantitative tightening, greater Treasury issuance, and heightened uncertainty about the economic outlook. However, survey-based measures likely overstated the rise in term premiums due to their delayed response to economic developments, a sluggishness, for which we provide formal evidence. We find that as yields declined, expectations likely played a relatively larger role amid a series of lower than expected data prints. Additionally, we identify a useful rule of thumb that emerges when averaging across the models: a rise in the slope (10-year minus 2-year) corresponds nearlyone-to-one with a rise in term premiums, while changes in the 2-year yield seem to be evenly split between expectations and term premiums.
