For the second month in a row the non-farm payroll and the household employment reports have diverged. The establishment survey came in at less than half of consensus expectation at 199,000 new jobs, while the household measure registered 651,000 new jobs for the month. That measure was enough to push the unemployment rate down to 3.9%, and just above the post-financial crisis low of 3.5%. That comes on the back of the surprisingly hawkish minutes of the December 15th FOMC meeting. Not only did the minutes solidly indicate a March rise in Fed Funds, the committee apparently had a meaningful discussion on the appropriate size of the Fed balance sheet under normal circumstances. That discussion included how fast they would allow a runoff of maturing securities. The minutes failed to detail a targeted amount, but it’s certainly well below the current balance of $8.2 trillion. They did indicate that a “substantial buffer” is the likely target. Also, some participants favor a complete runoff of the Fed’s mortgage-backed holdings in favor of Treasury debt. That last point could become problematic in a rising rate environment. Mortgage-backed securities are negatively convex, which is to say that as interest rates rise the duration extends. In a rising interest rate environment home owners are less likely to refinance and the pace of maturing MBS would slow, perhaps materially.
