Social Security is currently running a surplus and the accumulated holdings of SS are suppose to reach something like $4trillion in the late 'teens. As the baby-boomers begin to draw SS benefits, that $4tril will be depleted over a quarter of a century -- the accumulation will reach zero around 2042 -- thereafter, outpayments will be limited to inpayments.
At least that's the usual catechism. But there's an ambush awaiting SS recepients and it's not the political Right trying to dismantle the program. The force that is going to dismantle this program is greater than Republicans acting alone -- it's unfortunately bi-partisan.
The Fed holds about $700bil of Treasury securities -- that's about 10% of "total"
Treasury debt and about
Treasuries held by the "public" are
traded in the market whereas intragovernmental holdings (such as Soc Sec) are
not traded in the market -- they hold bookkeeping entries or
'non-marketable Treasuries.'

It is tempting to conclude that politicians merely look at the debt series which suits their interest -- they point the press towards the total series when it is rising least rapidly and they point towards the public series when that one looks best.
But why should Republicans have been willing to recognize the budget in the
last years of the Clinton Administration as being in 'surplus' when, in fact, the
total series was rising?
Answer: Because a decision had to be made -- what should they do with that excess cash flow in the
late 'nineties? The Democrats wanted to use the 'surplus' to retire Treasuries held by the public and the
Republicans wanted to use the 'surplus' to lower taxes.
As the Bush deficit became large in 2003/04, the Republicans have, indeed, tried to shift attention back to the 'public' series -- which is rising less rapidly -- by arguing that the total national debt which
The point of this essay is to argue that the essential meaningfulness of the intragovernmental trust funds is exactly what undermines the notion that SS is "fully funded" for multiple decades.
The blue bars below represent Soc Sec Treasury holdings: SSt.
The change in SS holdings, ΔSSt, averaged about $250bil/yr over the 10 years shown in the chart on the left. This quarter-of-a-trillion cash flow feeds into general Treasury revenue each year -- it is pure gravy for the national political process to allocate.
But sometime in the late 'teens, the $4 tril or so of SSt is
expected to peak and start its long decline. When a sufficient number of baby
boomers have retired the $4tril SS accumulation will begin its long decline. Over
a quarter century it will decline at the approximate average rate of $160bil/yr (=
4000bil/25yrs).
I.e., ΔSSt ≈ -$160bil/yr from
say 2015 to 2040.
When ΔSSt turns negative, the government will have to feed SS
something like $160bil/yr of cash rather than receive the current
quarter-of-a-trillion/yr cash from SS. Cash flow between the Treasury and SS will
reverse by $400/bil/yr or so. To meet this reversal of cash flow the federal government
will have to

This may be the long-awaited "reform" of SS which could, if payments are cut sufficiently, extend the life of the SS accumulated holdings by decades. Retired baby-boomers could take a hit so their children could get more. |
