Suppose that, in the expectation that some commodity will rise in price, he determines not only to invest in it all his ready money, but to take up on credit, from the producers or importers, as much of it as their opinion of his resources will enable him to obtain. Every one must see that by thus acting he produces a greater effect on price than if he limited his purchases to the money he has actually in hand. He creates a demand for the article to the full amount of his money and credit taken together, and raises the price proportionally to both. And this effect is produced, though none of the written instruments called substitutes for currency may be called into existence; though the transaction may give rise to no bill of exchange, nor to the issue of a single bank-note. The buyer, instead of taking a mere book-credit, might have given a bill for the amount, or might have paid for the goods with bank-notes borrowed for that purpose from a banker, thus making the purchase not on his own credit with the seller, but on the banker’s credit with the seller, and his own with the banker. Had he done so, he would have produced as great an effect on price as by a simple purchase to the same amount on a book-credit, but no greater effect. The credit itself, not the form and mode in which it is given, is the operating cause. § 3. Great extensions and contractions of Credit. Phenomena of a commercial crisis analyzed. The inclination of the mercantile public to increase their demand for commodities by making use of all or much of their credit as a purchasing power depends on their expectation of profit. When there is a general impression that the price of some commodity is likely to rise from an extra demand, a short crop, obstructions to importation, or any other cause, there is a disposition among dealers to increase their stocks in order to profit by the expected rise. This disposition tends in itself to produce the effect which it looks forward to—a rise of price; and, if the rise is considerable and progressive, other speculators are attracted, who, so long as the price has not begun to fall, are willing to believe that it will continue rising. These, by further purchases, produce a further advance, and thus a rise of price, for which there were originally some rational grounds, is often heightened by merely speculative purchases, until it greatly exceeds what the original grounds will justify. After a time this begins to be perceived, the price ceases to rise, and the holders, thinking it time to realize their gains, are anxious to sell. Then the price begins to decline, the holders rush into the market to avoid a still greater loss, and, few being willing to buy in a falling market, the price falls much more suddenly than it rose. Those who have bought at a higher price than reasonable calculation justified, and who have been overtaken by the revulsion before they had realized, are
