I mentioned a week and a half ago that I’d had a “really cool” idea that I had mentioned to a member of the Fed’s Open Market Desk, and I promised to write about it soon. “It’s an idea that would simultaneously be really helpful for investors and help the Fed reduce a balance sheet that they claim to be happy with but we all really know they wish they could reduce”. First, some background.

It is currently not possible to directly access any inflation index other than headline inflation (in any country that has inflation-linked bonds, aka ILBs). Yet, many of the concerns that people have do not involve general inflation, of the sort that describes increases in the cost of living and erodes real investment returns (hint – people should care, more than they do, about inflation), but about more precise exposures. For examples, many parents care greatly about the inflation in the price of college tuition, which is why we developed a college tuition inflation proxy hedge which S&P launched last year as the “S&P Target Tuition Inflation Index”. But so far, that’s really the only subcomponent you can easily access (or will, once someone launches an investment product tied to the index), and it is only an approximate hedge.

This lack has been apparent since literally the beginning. CPI inflation derivatives started trading in 2003 (I traded the first USCPI swap in the interbank broker market), and in February 2004 I gave a speech at a Barclays inflation conference promising that inflation components would be tradeable in five years.

I just didn’t say five years from when.

We’ve made little progress since then, although not for lack of trying. Wall Street can’t handle the “basis risks,” management of which are a bad use of capital for banks. Another possible approach involves mimicking the way that TIGRs (and CATS and LIONs), the precursors to the Treasury’s STRIPS program, allowed investors to access Treasury bonds in a zero coupon form even though the Treasury didn’t issue zero coupon bonds. With the TIGR program, Merrill Lynch would put normal Treasury bonds into a trust and then issue receipts that entitled the buyer to particular cash flows of that bond. The sum of all of the receipts equaled the bond, and the trust simply allowed Merrill to disperse the ownership of particular cash flows. In 1986, the Treasury wised up and realized that they could issue separate CUSIPs for each cash flow and make them naturally strippable, and TIGRs were no longer necessary.
