Today the Congressional Budget Office slammed the president's unrealistic budget presented recently, concluding that the cumulative deficit over the decade between 2011-2021 would be $9.5 trillion, or $2.3 trillion higher than that estimated by the White House. The reason for the differences according to the CBO is "differences in the underlying projections of what would happen under
current law ($1.3 trillion) as well as from differing assessments of the
effects of the President’s proposals ($1.0 trillion)." Then again, as we fail to recall when was the last time even the slightly more realistic CBO predicted a correct cumulative deficit ten years forward, we are fairly certain both will vastly underestimate the actual deficit by 2021. And as gross debt issuance tends to run about 50% over cumulative deficits, Zero Hedge expects that the best case scenario is for $15 trillion in debt issuance over the next 10 years as a baseline, and likely far more (bringing total marketable debt to around $25 trillion by 2021). This is problematic to say the least, because as the AP notes, the White House's goal is to reach a point where the budget is balanced
except for interest payments on the $14 trillion national debt. Such
"primary balance" occurs when the deficit is about 3 percent of the size
of the economy, and economists say deficits of that magnitude are
generally sustainable. Instead, just the interest expense per the CBO will be greater than this threshold: "Outlays would be greater under the President’s budget than in CBO’s baseline in each of the next 10 years, largely because the proposed reduction in revenues would boost deficits and thus the costs of paying interest on the additional debt that would accumulate. In particular, net interest payments would nearly quadruple in nominal dollars (without an adjustment for inflation) over the 2012–2021 period and would increase from 1.7 percent of GDP to 3.9 percent." And once again, this is based on numbers which will likely way undershoot the final outcome.
