Yeah, for one your data is just all off. For instance, you reference Table 26 in the BLS PDF, but incorrectly state that the CPI-U was 9.56% for 1983, when Table 26 actually says the CPI-U (average of 1983) was 3.2%. Your St. Louis Fed link (output to PDF and dividing by 12) gives me an average of 9.09% for the Fed Funds rate 1983, while you state it was 2.56%. Here is a
link to my Excel output from St. Louis Fed.
Sorry, I accidently transposed the labels of the data when I posted them into my post.
Thanks for pointing that error out. I have corrected it in my post above.
My point remains the same. CPI and interest rates tend to go hand-in-hand. CPI and interest rates were both at local minimums in Dec 1976. CPI and interest rates were both at or near local maximums in Mar 1980. The bulk of Volker's term was lowering interest rates which went with lowered CPI.
My claim vs eskimospy's claim:
My claim in as few words as I can make it: CPI and inflation rates are positively correlated (when one is high the other is high; when one is low the other is low). Eskimospy's claim is that they are negatively correlated (when one is high the other is low). From post #13 in this thread:
Second, you have the relationship between interest rates and inflation backwards. Higher interest rates make inflation LOWER, not higher. A fed rate of around 4% would cause a catastrophic deflationary spiral.
My challenge to Anandtech P&N:
Many central banks are strongly considering increasing inflation rates. I don't have a perfect crystal ball for forcasting the Fed. But I suspect that the US Fed wants to raise rates before the next election is in full swing. Thus interest rates will likely start to increase this winter and then pause during the summer/fall of 2016 and then maybe start increasing again after the election is over. I also suspect that other coutries will start raising rates as well (without the election hiatis). All of these increases will likely be quite slight and timid. If that occurs, three things can happen:
1) CPI can increase, like I feel it would (although the change would be timid if interest rate changes are timid).
2) CPI can be roughly the same.
3) CPI can decrease, putting us at or near deflation territory (as eskimospy claims).
Lets find out who is correct. How long should we wait? Lets go 3 to 5 years out and observe during that time period. 3 to 5 years from now are inflation and CPI both up from today's values? Or is one up and one down? Lets have actual data show if I am correct or if eskimospy is correct.
Challenge Basis:
Current US CPI-U (Seasonally adjusted for Apr 2015, from Table A of
http://www.bls.gov/cpi/cpid1504.pdf): 0.1%.
Current US Federal Funds Rate average for Apr 2015 (
https://research.stlouisfed.org/fred2/series/FEDFUNDS/downloaddata): 0.12%.
Challenge Verification:
Approximately annually I will post the current seasonally adjusted CPI-U from the BLS website and the current federal funds rate from the St. Louis Fed website. If the websites or website links change, I will post the same data as best as I can from a similar website. The latest revisions, if any, to that data will be used.
I claim that in the 3 to 5 year period from now that if the US Federal Funds Rate would be higher than that basis, then US CPI-U will also be higher. Eskimospy's first claim said we'd be in deflation if the Federal Funds rate goes higher.
Potential Challenge Extension:
The US Fed could sit on interest rates during that time period. If so, I would be willing to extend the length of time for the challenge to be 3 to 5 years after the US Fed finally does raise the federal funds rates.
