August Inflation Rises 0.2%: What It Means For Social Security, TIPS, And I Bonds

Summary

August headline inflation came in below the consensus for the month and year. Core inflation was also below the consensus.
The current trend in CPI-W would place the 2019 Social Security cost-of-living increase in a range of 2.7% to 3.0%, with one month remaining for the calculation.
Non-seasonally adjusted inflation increased just 0.06% in August, after a 0.01% increase in July. What does this mean for TIPS and I Bonds?
