Jeremy Grantham is Not Optimistic - Part 64

Some excerpts from Jeremy Grantham’s latest quarterly letter(.pdf) on Investing in a Low-Growth World:

Some information came out after the 4Q 2012 Letter or was missed by us and is worth mentioning. First, the Congressional Budget Office slashed its estimate of the U.S. long-term growth trend from 3.0% to 1.9%! Given the source and the magnitude of the adjustment, I think it is fair to say that their number is “close enough for government work” to our 1.5%.
…
The Fed’s negative real rates regime, designed to badger us into riskier investments in order to push up equity prices and grab a short-term wealth effect (that must be given back one day when least comfortable and least expected), has gone on for a long and, for me, boring time.
…
This doesn’t really fit in with a quarterly letter emphasizing important good news, but being about the Fed, I have to make an exception. The Fed appears to be still assuming a 3% growth rate for future U.S. GDP. It would be safer and more confidence-inspiring, now that Bernanke appears to take his responsibility for growth seriously, that he at least have a reasonable growth target (preposterous as that notion is to me that the Fed should or even could affect long-term growth simply by messing about with interest rates). The growth in available man-hours has definitely declined by about 1% a year, yet Bernanke’s assumption for our GDP’s normal trend growth appears unchanged at its old 3%.
…
Courtesy of the above Fed policy, all global assets are once again becoming overpriced. This reminds me of the idea sometimes attributed to Einstein that a workable definition of madness is constantly repeating the same actions but expecting a different outcome!

It’s not clear where the 1.9 percent growth rate came from in that first paragraph  above since page 5 of the CBO’s The Budget and Economic Outlook from the other day puts GDP growth at 2.2 percent for 2019 to 2023.

Otherwise, he seems to be spot-on.
