Corporate cash-pool valuation in a multi-firm context: a closed formula

Following our earlier paper on the subject, we present a general closed formula to value the interest savings due to a multi-firm cash-pool system. Assuming normal distribution of the accounts the total savings can be expressed as the product of three independent factors representing the interest spread, the number and the correlation of the firms, and the time-dependent distribution of the cash accounts. We derive analytic results for two special processes one characterizing the initial build-up period and the other describing the mature period. The value gained in the stationary system can be thought of as the interest, paid at the net interest spread rate on the standard deviation of the account. We show that pooling has substantial value already in the transient period. In order to increase the practical relevance of our analysis we discuss possible extensions of our model and we show how real option pricing technics can be applied here.

Debt Restructuring in the Euro Area: a Necessary but Manageable Evil?

There are two possible responses to the Greek debt crisis: ‘Plan A’, continued official lending, for as long as needed, with possible voluntary private sector involvement, and ‘Plan B’, coercive preemptive or post-default restructuring with significant face value reduction in privately-held debt. Both options have risks, but it is necessary to move to Plan B sooner or later. The impact on Greece could be mitigated by foreign bank ownership and proper liquidity support measures. The direct spillover impact on the rest of the euro area seems small. But there is the risk of contagion, which is a serious concern. There is a cautious case for delaying somewhat Plan B in order to prepare for it.
