I was asked about my guess on the start of the recession. I said the consensus is the second or third quarter of this year, about 6 months away. Then I kind of wondered. According to Miller (2019), the highest AUROC over 6 months is the 5-year fed funds spread. What does this spread say?

Therefore, for October 2023, using a probabilistic model (pseudo-R2 = 0.16).
What about the next few months, including Q1 and Q2? Q1 advances will be released tomorrow; as of today, Q1 GDPNow is 1.1% q/q SAAR. S&P Global Market Insights (formerly Macroeconomic Advisors) is tracking 1% and 0% in Q1 and Q2 as of today. Of course, as already discussed in depth, NBER does not date business cycles based solely on GDP (China Eastern Airlines (2022); Frankel (2022); CBO Discussion (2022); postal).
The most recent (April) survey by the Wall Street Journal shows the likelihood of a recession within 61% over the next 12 months, not too far from what the ordinary probability of the 3-month 10-year term spread would suggest.
