The price of funded property is not a steady criterion by which to judge of the rate of interest. In time of war, the stock market is so loaded by the continual loans of Government, that the price of stock has not time to settle at its fair level before a new operation of funding takes place, or it is affected by anticipation of political events. In time of peace, on the contrary, the operations of the sinking fund, the unwillingness, which a particular class of persons feel to divert their funds to any other employment than that to which they have been accustomed, which they think secure, and in which their dividends are paid with the utmost regularity, elevates the price of stock, and consequently depresses the rate of interest on these securities below the general market rate. It is observable too, that for different securities, Government pays very different rates of interest. Whilst 100_l._ capital in 5 per cent. stock is selling for 95_l._, an exchequer bill of 100_l._, will be sometimes selling for 100_l._ 5_s._, for which exchequer bill, no more interest will be annually paid than 4_l._ 11_s._ 3_d._: one of these securities pays to a purchaser at the above prices, an interest of more than 5-1/4 per cent., the other but little more than 4-1/4; a certain quantity of these exchequer bills is required as a safe and marketable investment for bankers; if they were increased much beyond this demand, they would probably be as much depreciated as the 5 per cent. stock. A stock paying 3 per cent. per annum will always sell at a proportionally greater price than stock paying 5 per cent., for the capital debt of neither can be discharged but at par, or 100_l._ money for 100_l._ stock. The market rate of interest may fall to 4 per cent., and Government would then pay the holder of 5 per cent. stock at par, unless he consented to take 4 per cent., or some diminished rate of interest under 5 per cent.: they would have no advantage from so paying the holder of 3 per cent. stock, till the market rate of interest had fallen below 3 per cent. per annum. To pay the interest on the national debt, large sums of money are withdrawn from circulation four times in the year for a few days. These demands for money being only temporary, seldom affect prices; they are generally surmounted by the payment of a large rate of interest.[36] CHAPTER XX. BOUNTIES ON EXPORTATION, AND PROHIBITIONS OF IMPORTATION. A bounty on the exportation of corn tends to lower its price to the foreign consumer, but it has no permanent effect on its price in the home market.
