Goldman's latest analysis of the US budget shows a staggering gap of $8 trillion in the next 10 years. This materially diverges from the latest White House projection as well as from the CBO's "baseline".
GS: - Through 2022, we forecast a cumulative deficit of roughly $8 trillion (3.9%) under a "business as usual" assumption that envisions extension of most current policies but no further deficit reduction measures.
CBO's key assumptions are discussed in this slide presentation (for more on this topic, including the discussion of CBO's "Alternative Scenario" see this update):
GS: - The two main risks to the forecast are related, but work in opposite directions. First, there is a clear possibility of greater fiscal restraint than we assume in our forecast [presumably due to a change in Washington]. While we assume that most of the spending reductions enacted in 2011 will be maintained, we make no assumption regarding the enactment of another round of deficit reduction measures in 2013. The second risk, working in the opposite direction, is that growth could come in under our forecast, particularly if the first risk--tighter-than-expected fiscal policy--does indeed materialize.This does not bode well for the US public debt levels going forward no matter who is in the White House. The following chart shows Goldman's projection (compared with the White House and the CBO) of the US debt to GDP ratio - creeping toward mid 80s. A number of economists unaffiliated with the government or with GS think Goldman's forecast is quite realistic and may in fact be a bit optimistic.
