Everything can be sold. Depends on the price.
A bond gives you fixed payouts each year and then a final payout of the face value of the bond at maturity.
A $1000 bond at 5% will give you $50 per year and then a big bonus payment of $1000 when the bond matures.
If the bond is trading at its face value of $1000, the effective yield is 5%. You get 5% a year plus your money back when the bond expires.
But let's say you are a private equity firm buying toxic debt from the Treasury. You might say, I'm not paying $1000 (face value). I want a big discount!
A 50% discount means you could buy that bond for $500. Your yearly payout is still $50/year. That means every year you are getting 10% back on your money. That's an incredible payout in this environment.
But it gets better.
When the bond matures (say, ten years), you get $1000 back, not $500.
That means your effective return over that ten year span is nearly
15%.Sure, there is risked involved with buying this obviously risky asset but the potential rewards are equally huge. If the Treasury offers any kind of guarantee on the debt, maybe an insurance plan to protect the private investor against default risk...this "toxic" debt could become gold for investors.
In fact, this is EXACTLY what lead to the current mess in the first place. The only difference is that instead of an insurance policy issued by a corrupt insurance company that never created a cash reserve to payout the policies (AIG...), you would be getting an insurance policy from a corrupt government that has a nearly unlimited capacity to pay out your policy.
It would go from being high risk junk bonds to as risk free as Treasury Bonds. The difference is that
these bonds would actually be guaranteed by the full faith and credit of the US Federal Government, not merely rubber stamped by some phony credit agency as Triple A.
Long story short, if they start offering serious discounts and government-paid default protection on these bonds, private investors will buy them by the boatload.
