For all the talk about a flattening U.S. yield curve, it is ironic that it steepened last week, albeit slightly. The trend, though, is clear enough. The 2s5 and 2s10s have flattened 27 and 32 basis points in the past year, respectively. Another 12 months at this rate and the curve would invert by the middle of next year. This wouldn’t be odd. It’s normal for the curve to flatten as monetary policy is tightened, and it is also normal for the Fed to keep going until the curve inverts.
If you believe that an inverted curve is a good recession indicator—which is debatable—this is tantamount to saying that the Fed will keep going until something breaks, consistent with what almost always happens at the tail-end of policy tightening cycles. This probably won’t prevent investors and analysts from continuing to pay close attention to the yield curve.
I have sympathy for that, for two reasons. Firstly, it is not clear to markets whether the Fed cares about a flattening curve or not. Some members of the FOMC do, some don’t. Secondly, if the shape of the curve is important to the Fed, the recent pace of curve flattening challenges the prediction by economists and markets that the Fed funds rate will be hiked by 25 basis points three-to-four times in 2018 and 2019.
