It should be noted that regional pooling is efficient only when countries are facing asymmetric liquidity shocks within the region. Pooling brings no additional benefits when shocks occur on a global scale and all countries are hit simultaneously. Also, regional arrangements cannot avoid the moral hazard problem that all multilateral schemes are facing. Nevertheless, there seems to be considerable scope for regional arrangements to prosper in the future. First, they can act as useful complements to more global schemes and be articulated with (and supported by) IMF facilities. Second, one can expect regional financial integration to progress, especially in those parts of the world where huge pools of savings are available and currently intermediated through financial systems located outside the region. With deeper financial integration, the probability of significant portfolio shifts inside one region increases markedly, creating the potential for asymmetric liquidity shocks. The development of regional liquidity arrangements may appear very useful to underpin the development of regional financial markets. Stores of value One consequence of the crisis has been to cast doubts on the ability of some assets, up to now considered as riskless, to serve as reliable stores of value. The ability of the private sector to create “safe” assets through financial innovation has proved largely illusory (Caballero, 2009). So, in the period to come there may be both an increased demand worldwide for risk free assets and much less certainty on their future supply.
