“The G fund is a close as the TSP comes to having a cash account and is invested in special issue treasury bonds.”
Special issue treasury bonds are just another fraudulent accounting scheme. You have been duped into believing that these non marketable TBills have some economic significance. The Social Security Administration has a warehouse full of this fraudulent and worthless paper.
The only possible significance is if Congress prevented Obama from spending beyond the debt limit. Since Congress will lift the debt limit, this transfer is just a non economic event.
Probably no more or less fraudulent than any other treasury bond or dollar bill for that matter.
When push comes to shove, they're all only worth what the government tells us they're worth.
