TIPS-backed Money Market Funds
Posted: Tue Jul 07, 2009 9:30 pm
By coincidence, they were discussing the subject of T-bill backed
money market funds on CNBC this morning with a guy from Pimco. In
particular, they were discussing TIPS (Treasury Inflation-Protected
Securities)
TIPS are inflation-protected, in the sense that the amount you
receive upon redemption is increased by the amount of inflation
that's occurred since they were issued.
The discussion this morning had to do with deflation. TIPS are also
protected from deflation, in the sense that the amount you receive at
the is not reduced if deflation has occurred, so your principal is
protected.
However, this isn't true if you're invested in a money-market fund
backed by TIPS. Since you own fund shares, rather than actual TIPS
certificates, you will lose principal if there's deflation.
(There's apparently a technical reason for this. When you buy shares
in a MMF backed by TIPS, then you're investing in TIPSs that may be a
few years old, and have already accrued some value through inflation.
If deflation occurs from that point on, then the value already
accrued through inflation is not protected.)
So now the question is: How much deflation might we have?
I actually addressed this question in 2004.
** CPI data points to deflation trend
** http://www.generationaldynamics.com/cgi ... 17#e040717
At that time, based on long-term trends, I estimated that the CPI
would fall by 30% by 2010.
I would no longer be certain of the 2010 date, but I stick by the 30%
figure, probably by 2012 or so.
That would be a real disavantage of MMFs backed by TIPS, but
presumably is not a disadvantage for people who obtain TIPS from
TreasuryDirect.gov, as Ms. Bluebird and Mr. Higgenbotham suggest.
Sincerely,
John
