Declining Inflation Expectations
The University of Michigan's long-run inflation expectations (top chart) and the 10-year CMT-10 year TIPS rate (bottom) chart are both declining. The University of Michigan's estimate has always been a bit high; it was 3-3.5% in 2012-2014 and has moved lower to 2.5%. The bond market measure is lower but probably more accurate. Either way, both have moved lower by about 50-65 basis points in the last 3-4 years, which has important ramifications for Fed policymakers.
Yield Curve Flattening
Since the beginning of the year, the curve has definitely flattened, with most of the movement coming in the short-end of the curve.
