In today’s Financial Times, Jeffrey Sachs uses a hypothetical to explain why the Geithner bank bailout plan is a bad idea:
Consider a simple example: a toxic asset with face value of $1m pays off fully with probability of 20 per cent and pays off $200,000 with probability of 80 per cent. A risk-neutral investor would pay $360,000 for this asset.
Along comes the government and says it will finance 90 per cent of the investor’s purchase and, moreover, do so as a non-recourse loan. Non-recourse means the government’s loan is backed only by the collateral value of the toxic asset itself. If the pay-out is low, the loan is defaulted and the government ends up with the low pay-out rather than full repayment of the loan.
Now the investor is prepared to bid $714,000 (with rounding) for the same asset. The investor uses $71,000 of his/her own money and $643,000 of the government loan. If the asset pays off in full, the investor repays the loan, with a profit of $357,000. This happens 20 per cent of the time, so brings an expected profit of $71,000. The other 80 per cent of the time the investor defaults on the loan, and the government ends up with $200,000. The investor just breaks even by bidding $714,000, as we would expect in a competitive auction.
Of course, the investor has systematically overpaid by $354,000 (the bid price of $714,000 minus the market value of $360,000), reflecting the investor’s right to default on the loan in the event of a poor pay-out of the toxic asset. The overpayment equals the expected loss of the government loan. After all, 80 per cent of the time (in this example) the government loses $443,000 (the $643,000 loan minus the $200,000 repayment). The expected loss is 80 per cent of $443,000, equal to $354,000.
The idea of “private sector price discovery” is therefore flim-flam. There would be price discovery if the government’s loan had to be repaid whether or not the asset paid off in full. In that case, the investor would bid $360,000. But under the Geithner-Summers plan the loan is precisely designed to be a one-way bet, for the purpose of overpricing the toxic asset in order to bail out the bank’s shareholders at hidden cost to the taxpayers.
There are only two ways this can work itself out.
Either the plan succeeds and the private investors walk away with the profits, or it fails and the taxpayers are left holding the bag. Given the fact that these toxic assets we’re talking about are largely made up of subprime and at-risk mortgages, it’s far more likely that we’ll se the later outcome than the former.
