It might seem obvious to follower of the Austrian School of economics that fractional-reserve banking “inevitably expands the money supply,” causing cycles of boom, bust and malinvestment. But the reptilian brains in Congress need someone like Dr. Joseph T. Salerno to explain to them the consequences of “issuing deposits not fully backed by cash.” This Salerno, whose lectures I enjoyed at the Mises Institute, has always done magnificently:

… when people deposit an additional $100,000 of cash in the bank, depositors now have an additional $100,000 in their checking accounts while the bank accumulates an additional $100,000 of cash (dollar bills) in its vaults. The total money supply, which includes both dollar bills in circulation among the public and dollar balances in bank deposits, has not changed. The depositors have reduced the amount of cash in circulation by $100,000, which is now stored in the bank’s vaults, but they have increased the total deposit balance that they may draw on by check or debit card by the exact same amount. Suppose now the loan officers of the bank lend out $90,000 of this added cash to businesses and consumers and maintain the remaining $10,000 on reserve against the $100,000 of new deposits. These loans increase the money supply by $90,000 because, while the original depositors have the extra $100,000 still available on deposit, the borrowers now have an extra $90,000 of the cash they did not have before.
The expansion of the money supply does not stop here however, for when the borrowers spend the borrowed cash to buy goods or to pay wages, the recipients of these dollars redeposit some or all of these dollars in their own banks, which in turn lend out a proportion of these new deposits. Through this process, bank-deposit dollars are created and multiplied far beyond the amount of the initial cash deposits. (Given the institutional conditions in the United States today, each dollar of currency deposited in a bank can increase the US money supply by a maximum of $10.00.) As the additional deposit dollars are spent, prices in the economy progressively rise, and the inevitable result is inflation, with all its associated deleterious effects on the economy.

Then there are the artificially low interest rates:

Fractional-reserve banking inflicts another great harm on the economy. In order to induce businesses and consumers to borrow the additional dollars created, banks must reduce interest rates below the market-equilibrium level determined by the amount of voluntary savings in the economy. Businesses are misled by the artificially low interest rates into borrowing to expand their facilities or undertake new long-term investment projects of various kinds. But the prospective profitability of these undertakings depends on expectations that bank credit will remain cheap more or less indefinitely. Consumers, too, are deceived by the lower interest rates and rush to purchase larger residences or vacation homes. They take out second mortgages on their homes to buy big-ticket luxury items. A false economic boom begins that is doomed to turn into a bust as soon as interest rates begin to rise again.
As the inflationary boom progresses and prices rise, the demand for credit becomes more intense at the same time that more cash is withdrawn from bank deposits to finance the purchase of everyday goods. The banks react to these developments by sharply raising interest rates and contracting loans and deposits, causing a decline in the money supply. Indeed the money supply may very well collapse, as it did in the early 1930s, because the public loses confidence in the banks and demands it deposits back in cash. In this case, a series of bank runs ensue that pushes many fractional-reserve banks into insolvency and instantly extinguishes their money substitutes, which had previously circulated as part of the money supply. Recession and deflation results and the binge of bad investments and overconsumption is starkly revealed in the abandoned construction projects, empty commercial buildings, and foreclosed homes that litter the economic landscape. At the end of the recession it turns out that almost all households and business firms are made poorer by fractional-reserve bank-credit expansion, even those who may have initially gained from the inflation.

UPDATE (Feb. 20): QE ad infinitum. Federal Reserve and US government, a cog in the fractional reserve operation, buy up their own debt. The country is collateral. The purchases of government debt securities is known as “quantitative easing,” or QE ad infinitum.

The money mafia are easing to the tune of $85 billion in monthly bond purchases. If they’ve admitted to this much, you can be sure it’s much more.

The basis for debauching the coin? The Fed and his political masters assume that inflating the money supply and endless liquidity alleviate joblessness.

It’s the exact opposite.

The Fed’s latest shenanigans via Bloomberg:

Several Federal Reserve policy makers said the central bank should be ready to vary the pace of their $85 billion in monthly bond purchases amid a debate over the risks and benefits of further quantitative easing.
The officials “emphasized that the committee should be prepared to vary the pace of asset purchases, either in response to changes in the economic outlook or as its evaluation of the efficacy and costs of such purchases evolved,” according to the minutes of the Federal Open Market Committee’s Jan. 29-30 meeting released today in Washington.
The minutes showed policy makers were divided about the strategy behind Chairman Ben S. Bernanke’s program of buying bonds until there is “substantial” improvement in a U.S. labor market burdened with 7.9 percent unemployment, with some saying an earlier end to purchases might be needed, and others warning against a premature withdrawal of stimulus.
“They’re changing the debate toward when to scale it down rather than debating the point where it suddenly ends,” said Jim O’Sullivan, chief U.S. economist at High Frequency Economics in Valhalla, New York. “With the economy looking more solid than they feared a few months ago, financial sector risks take on more importance.”
