The Wealth of Nations_ Books 4-5 - Adam Smith [62]
It might be otherwise during a public calamity; an invasion, for example, such as that of the French in 1672. The owners of bank money being then all eager to draw it out of the bank, in order to have it in their own keeping, the demand for receipts might raise their price to an exorbitant height. The holders of them might form extravagant expectations, and, instead of two or three per cent., demand half the bank money for which credit had been given upon the deposits that the receipts had respectively been granted for. The enemy, informed of the constitution of the bank, might even buy them up, in order to prevent the carrying away of the treasure. In such emergencies, the bank, it is supposed, would break through its ordinary rule of making payment only to the holders of receipts. The holders of receipts, who had no bank money, must have received within two or three per cent. of the value of the deposit for which their respective receipts had been granted. The bank, therefore, it is said, would in this case make no scruple of paying, either with money or bullion, the full value of what the owners of bank money who could get no receipts were credited for in its books; paying at the same time two or three per cent. to such holders of receipts as had no bank money, that being the whole value which in this state of things could justly be supposed due to them.
Even in ordinary and quiet times it is the interest of the holders of receipts to depress the agio, in order either to buy bank money (and consequently the bullion, which their receipts would then enable them to take out of the bank) so much cheaper, or to sell their receipts to those who have bank money, and who want to take out bullion, so much dearer; the price of a receipt being generally equal to the difference between the market price of bank money, and that of the coin or bullion for which the receipt had been granted. It is the interest of the owners of bank money, on the contrary, to raise the agio, in order either to sell their bank money so much dearer, or to buy a receipt so much cheaper. To prevent the stock-jobbing tricks which those opposite interests might sometimes occasion, the bank has of late years come to the resolution to sell at all times bank money for currency, at five per cent. agio, and to buy it in again at four per cent. agio. In consequence of this resolution, the agio can never either rise above five or sink below four per cent., and the proportion between the market price of bank and that of current money is kept at all times very near to the proportion between their intrinsic values. Before this resolution was taken, the market price of bank money used sometimes to rise so high as nine per cent. agio, and sometimes to sink so low as par, according as opposite interests happened to influence the market.
The bank of Amsterdam professes to lend out no part of what is deposited with it, but, for every guilder for which it gives credit in its books, to keep in its repositories the value of a guilder either in money or bullion. That it keeps in its repositories all the money or bullion for which there are receipts in force, for which it is at all times liable to be called upon, and which, in reality, is continually going from it and returning to it again, cannot well be doubted. But whether it does so likewise with regard to that part of its capital, for which the receipts are long ago expired, for which in ordinary and quiet times it cannot be called upon, and which in reality is very likely to remain with it for ever, or as long
