So long as the savings remain in possession of their owners, these hazardous gamblings in speculative undertakings are almost the whole effect of an excess of accumulation over tested investment. Little effect is produced on the general trade of the country. The owners of the savings are too scattered and far from the market to change the majority of mercantile transactions. But when these savings come to be lodged in the hands of bankers, a much wider result is produced. Bankers are close to mercantile life; they are always ready to lend on good mercantile securities; they wish to lend on such securities a large part of the money entrusted to them. When, therefore, the money so entrusted is unusually large, and when it long continues so, the general trade of the country is, in the course of time, changed. Bankers are daily more and more ready to lend money to mercantile men; more is lent to such men; more bargains are made in consequence; commodities are more sought after; and, in consequence, prices rise more and more. The rise of prices is quickest in an improving state of credit. Prices in general are mostly determined by wholesale transactions. The retail dealer adds a percentage to the wholesale prices, not, of course, always the same percentage, but still mostly the same. Given the wholesale price of most articles, you can commonly tell their retail price. Now wholesale transactions are commonly not cash transactions, but bill transactions. The duration of the bill varies with the custom of the trade; it may be two, three months, or six weeks, but there is always a bill. Times of credit mean times in which the bills of many people are taken readily; times of bad credit, times when the bills of much fewer people are taken, and even of those suspiciously. In times of good credit there are a great number of strong purchasers, and in times of bad credit only a smaller number of weak ones; and, therefore, years of improving credit, if there be no disturbing cause, are years of rising price, and years of decaying credit, years of falling price.
