The two main Irish bank shares fell back again today following the announcement of the details of the recapitalization — down 16 and 14 per cent respectively. There could be lots of reasons. To begin with there was the extraneous factor of the back-to-back deposits between Anglo and ILP mentioned in a previous post. ILP fell back 15 per cent as well.
Then there is the possibility that shareholders expected a more lenient deal? But how lenient could that have been? The interest rate on the preference shares is stiff enough, but not out of line with prevailing practice in other countries and anyway was well-flagged.
To all intents and purposes, however, the share prices are close to zero — down over 95 per cent on their peak.
My purpose in writing, though, is to point out that even though the preference shares are senior to equity, an injection sufficient to assure solvency going forward could nevertheless have been expected to lift ordinary share prices.
I suspect this is not a well-known effect. Permit me to present a very simple model.
Thus, suppose that there are just three periods. For convenience, assume our bank begins with zero capital.
In period 1, the government decides the amount S it will inject through purchase of preference shares.
In period 2 we discover the true state of the world, i.e. the size of the loan losses (H high in the bad state, L low in the good state). If the losses exceed the funds the government injected, then the bank is liquidated and the shareholders get nothing; If the losses are equal to or less than injection, then the bank continues in operation.
In period 3 the bank, if still in operation, earns franchise profits Z on the rest of its business. It is then wound up; the government receives its injection back if possible. Any surplus goes to the shareholders.
Clearly, if the values H and L are known and if the government injects any amount equal to or less than L, the market value of the shares at the end of period 1 is zero. (Of course, the analysis assumes rational market expectations.)
If the government injects more than that, the market value of the shares at the end of period 1 is p*max{0, (Z-L)}, where p is the probability of the good state. A longer expression gives the share value if the injection S is higher than H.
The point is that even an injection S that is only sufficient to ensure the bank’s survival in the good state will, when announced, increase the market value of the shares.
The Irish Government injection of yesterday was insufficient to do that.
