could use several instruments to separate the supply of reserve money (currency bills in circulation and deposits of the commercial banks in the central bank) from movements in their stock of gold. Two of these instruments related to the manipulation of interest rates. In the absence of a central bank, interest rates would increase when gold flowed out of the country and decline when it flowed in. This would au- tomatically equilibrate the market, as higher rates would attract capital in- flows when gold flowed out and lower rates would encourage capital outflows when gold flowed in. Countries with central banks, however, had the power to manipulate rates independently of gold flows. They did so in two primary ways. The first was fixing the rate of interest at which they were willing to lend money to commercial banks. This effectively established rates in the market. In Britain, the central bank lending rate was called the Bank 158 MONETARY SOVEREIGNTY AND GOLD Rate, or simply the Rate. It had other names in other countries, most commonly the discount rate. Central banks also engaged in so-called open market operations. Selling government securities into the market re- duced the amount of money in circulation, increasing interest rates, and buying government securities increased the amount of money in circula- tion, reducing interest rates.9 The use of these instruments empowered central banks to increase rates even as gold was flowing into the country, or reduce them even as it was flowing out. They could, however, only go against the natural tendency of the gold standard in the very short term. If a country was losing gold and market rates were rising, for example, a cen- tral bank pushing down rates would accelerate the speed at which the country was losing gold, further encouraging the trend of market rates to increase. The system also allowed for monetary creation by the various commer- cial banks. The broadest measure of money, commercial bank deposit money, could move up and down almost independently from gold move- ments. Peel s Act established no constraints on the creation of deposits by commercial banks and the granting of credit with the proceeds of the de- posits, so that banks could multiply the money issued by the Bank of En- gland.10 Thus, commercial bank deposits and transactions could grow at rates different from that of the supply of gold because of the influence of the multiplication of deposits carried out by the banking system. For ex- ample, reserve money could be contracting along with gold exports, yet the amount of deposit money could be growing if the multiplier of the banking system was increasing. When this happened, the ratio of reserves to deposits naturally declined because more deposit money was created out of the same amount of gold. The traditional representation of the gold standard takes it to be au- tomatic, nondiscretionary adjustment, write Rudi Dornbusch and Jacob Frenkel. Bullion flows are matched one-for-one by changes in the amount of currency outstanding. [But] this is, of course, not the case once the reactions of the [central bank] are taken into account. Changes in the reserve-deposit ratio of the [central bank] affect the money stock independently of the existing stock of bullion. 11 Dornbusch and Frenkel examined the accounts of the Bank of England during a financial crisis in 1847, and found that the Bank sterilized substantially the effects of the MONETARY SOVEREIGNTY AND GOLD 159 gold outflows that were taking place as a result, first, of trade deficits and, then, of capital flight. This resulted in a substantial reduction in the ratio of gold reserves at the central bank to bank deposits from 46% in Janu- ary to 19.6% in April, and then from 32% in June to 11.6% in October. Re- ducing this ratio allowed the Bank to create more money than allowed by the gold reserves it kept. Thus, the Bank was able to carry out monetary policy by allowing the ratio of reserves to deposits to vary over time, at least during crises. Students of a longer period, from the 1870s to the start of World War I in 1914, have also found that the Bank engaged in some countercyclical monetary policy, although within the context of main- taining currency convertibility (that is, people could convert currency into gold and export it).12 The discretionary power of the central banks was, however, very lim- ited in the longer term. The creation of discretionary money could result in one of two outcomes. If the economy needed the additional liquidity, it would absorb the newly created money with little or no inflation. If it was not needed, however, there would emerge an outburst of inflation, and the price of gold would rise in the market relative to its official price (that is, the price the central bank was committed to for redemptions). People would then exchange currency for gold, melt it, and sell it in the domestic market or export it.13 The falling stocks of gold in the central bank would contract the money supply, which in turn would lead to higher interest rates. The higher rates would encourage deposits and discourage credits, which would then result in a decline in demand for goods, including gold. This would result in deflation, which would continue until the market price of gold went down to the official level. While it was therefore possible to carry out monetary policies, the sys- tem automatically compensated for any excess in their implementation, leading prices back to their initial equilibrium. It guaranteed the long- term stability of prices and established incentives for central banks not to tamper with the supply of money, because any excess in one direction meant a subsequent adjustment in the other direction. Such adjustment, however, could be upset by either of two problems. First, the supply of gold available for minting could vary because of shifts
