That is not the route!
Not only does Garten analyze the issue of sovereign funds as if trying to carve out for himself the role as The High Priest of financial nativism but also, even if he was absolutely right about his deepest misgivings, the type of solutions he proposes, like requiring from the government owned investment companies that they “publish internationally audited reports on their entire portfolios at least twice a year” could not serve any rational purpose and could in fact even serve as a dangerous valium.
What on earth is Garten up to? Trying to extend Sarbanes Oxley to the rest of the world governments? Asking the credit rating agencies to rate the sovereign funds? Allowing these funds only to buy government paper? Good luck! This type of approach would only have much of the current world imbalances try to go underground, making them so much harder to manage. Do I then mean that sovereign funds do not pose any threat? Of course not…some do, the same way that some non-sovereign funds could also be dangerous for any sovereignty.
