27 March 2015 US Fixed Income Weekly A note on the cash curve and inflation Last autumn we noted historical evidence that 10s30s is forward looking with respect to inflation, and developed a simple indicator which illustrated that consistent bullish flattening (10s and 30s fall, 10s30s flattens) tends to presage a higher probability of declining inflation. The indicator is simple enough, we look at a rolling 20 trading day period and calculate the frequency of bullish flattening as a percentage of that 20 day period. Using Treasury data for lOs and 30s, and (month end) data from September 1994 until present, the unconditional probability of inflation declining over a 6m period was 53%. Conditioned upon a month-end bull flattening percentage of at least 60% (36 "events" during the historical period), the probability of CPI y/y falling over the subsequent 6m has historically been 75% (27 instances of falling inflation of the 36 events).

Indeed, our colleagues in economics currently project that headline CPI y/y will rise to 0.6% in M. Additionally conditions in the Middle East are obviously fluid and a deterioration in the security environment could push oil and inflation higher. On the other hand, a more aggressive Fed could lead to further dollar strength and renewed downward pressure on traded goods generally and oil in particular.
