Free banking means banking conducted without special regulations, treated like any other industry producing real goods, requiring no special government role beyond ordinary contract enforcement, especially under a commodity monetary base like a gold standard.

Banks in a free banking system can do everything central banks/governments do in the monetary system except contribute to crises, which government agencies are particularly good at doing.

The 'banking is too important to be left to the private sector' argument is weak because almost everything important (trade, food, agriculture) is left to markets; the real question is whether government involvement makes the sector work better.

Government interference with money and banking long predates the Federal Reserve and other central banks; the U.S. government wielded a heavy hand in banking well before 1913.

Two specific pre-Fed regulations—the lack of branch banking (forcing single-office unit banks) and heavy restrictions on banks' ability to issue currency—caused much of the financial chaos that later served as the rationale for creating the Fed.

Historically, under free banking, different banks issued notes with their own names but all represented claims to the same underlying gold standard, creating a uniform monetary standard without a monopoly issuer of paper money.

U.S. banks lost their right to issue notes in two Civil War stages: state banks were taxed out of note issuance, while federally chartered National Banks could only issue notes if backed more than fully by U.S. government securities—a design meant to finance the war, not to improve the monetary system.

Because National Bank notes had to be backed by government securities, as the government retired its post-Civil War debt it became exceedingly costly to supply currency, so the currency supply shrank even as the country grew rapidly, causing severe currency shortages and financial crises in the late 19th and early 20th centuries.

The Fed was essentially just 12 banks set up to issue currency when laws prevented national and state banks from doing so; there was nothing magic about it—the same problem could be solved by simply letting existing banks issue currency.

Under competitive note issuance, an individual bank that over-issues faces a reserve drain: notes it issues are received and returned for redemption by rival banks, draining its reserves, which strictly limits how much currency any single bank can create—the same discipline that constrains deposit creation today via check-clearing.

A monopoly note issuer escapes the reserve-drain discipline because its notes get treated like reserves by other banks even under a gold standard, allowing it to expand with impunity and encouraging all other banks to expand as well.

If a free bank ran out of gold in a panic it would shut down and be liquidated, but note and deposit holders often received a complete payout after some delay from the bank's assets and capital, which is why Scotland's overall loss figures were very modest despite occasional individual failures.

In free banking, a private clearinghouse acts as a banker's club that detects banks lending too aggressively before the public does, expelling them and prompting other banks to refuse their notes—as happened to the Ayr Bank in Adam Smith's day, which collapsed quickly with losses borne mainly by its shareholders.

Bank capital is the free-banking counterpart to deposit insurance: losses from bad loans are absorbed first by shareholders' capital, and only after capital is exhausted do depositors and note holders suffer—so customers choose well-capitalized banks for safety.

In the Scottish free banking system until 1845, total losses suffered by banknote holders were miniscule compared to the losses borne mostly by taxpayers from bank failures in modern central-banking times.

A bank note, unlike a deposit account, is a financial asset traded in a secondary market and priced by expert market makers, so any doubt about a bank's solvency causes its notes to trade at a discount immediately—giving note holders faster warning signals than a car buyer gets about product quality.

In a free banking system, customers face two screening decisions—which bank to entrust with their money, and which other banks' notes their bank accepts—so a bank's willingness to accept another's notes signals that bank's safety, and banks not in good standing get weeded out of the system.

Free banking is fractional reserve banking; in Scotland circa 1820 typical banks held gold reserves of only one to two percent because public faith was so high that almost no one redeemed notes—people actually preferred to deposit gold guineas in exchange for trusted bank paper.

The Scottish 'option clause' let banks suspend note redemption while paying note holders the maximum legal 5% interest during suspension, converting the note into a small bond; it developed to defend against rival banks staging note 'raids,' and was an incentive-compatible device never actually used against customer runs.

The option clause is incentive-compatible: if correctly designed with the right interest rate, it only pays a bank to invoke it (rather than wind up) when the bank is actually solvent but facing an irrational panic; an insolvent bank with bad loans gains nothing from invoking it and simply shuts down—so it creates no moral hazard.

Government schemes to eliminate depositor risk produce a less safe banking system overall: depositors stop facing losses but taxpayers face them instead, and those losses become greater and systemic rather than localized.

The belief that a good banking system is one where customers never face losses is fundamentally rotten; allowing banks to fail and customers to take losses is necessary, because removing that risk leads eventually to a system dominated by lousy banks.

Many Scottish banks had unlimited liability exposing shareholders' personal wealth, but even limited-liability ones held very large capital; what restrained free banks from opportunism was that bank owners had a great deal of their own wealth at stake.

The establishment of a lender of last resort and deposit insurance erodes bank capital because both are substitutes for capital in the eyes of depositors, which is why bank capital must now be regulated whereas before the Fed banks commonly held capital equal to 30% of liabilities.

Scottish free banking ended in 1845 due to the careless extension of England's Peel's Act to Scotland on the assumption that what was good for England suited Scotland too; the Act capped note issues and imposed 100% marginal reserve requirements, ultimately giving the Bank of England a currency monopoly without solving instability.

The ultimate reason for studying free banking is not libertarian advocacy but theory: just as understanding tariffs requires a model of free trade, understanding what central banks actually do and the harm they cause requires a theory of free banking, which most monetary economists lack.

Claims that central banks have 'gotten the hang of it' based on roughly a decade of moderate cycles ignore the many decades central banks screwed things up and amount to cherry-picking the sample period; the current crisis shows that apparent stability was setting the stage for another cycle.

The Fed played a very important part in pumping up the housing bubble, so the period of apparent stability and central-bank success was actually setting the stage for another cycle rather than evidence of mastery.

Central banking is inevitably the rule of human beings and discretion rather than rules and law, as seen when Greenspan, worried about 9/11 and the tech crisis, went too far to avert recession, and when Bernanke bailed out Bear Stearns in the name of saving a financial system that was not saved.

Free banking can operate on any monetary standard (gold, silver, or even a fiat dollar created by a central bank), so free banking by itself does not specify a particular pattern for the total money supply.

With free banking today you would not need an activist Fed, because the private banks can supply adequate amounts of every component of the money supply; the Fed's leverage rests only on its monopoly of paper currency and bank reserves, which becomes unnecessary if banks can freely issue notes and the monetary base (reserves) is simply frozen.

Under a frozen stock of bank reserves with free note issuance and no reserve requirements, the private banking system can still accommodate the public's changing money needs, because changes in money demand are met by banks expanding or contracting notes and deposits.

When public demand to hold money rises and velocity falls (people draw fewer checks, pass on fewer notes), free banks actually tend to issue more money because their demand for reserves is a function of payment flow through the clearing system; thus changes in velocity get offset by changes in the private money stock.

A bank not subject to reserve requirements and able to supply both currency and deposits can expand more the more slowly people spend its money; in the limiting case where nobody ever writes checks, a bank could expand forever because it would never lose reserves.

Maintaining a fairly stable level of total spending is key to dampening the business cycle, and a free banking system does this automatically because the money stock grows when velocity falls and shrinks when velocity rises.

Rules like the Taylor rule fail because they use the price level as a proximate signal of whether there is too much or too little money, which is misleading; what matters for dampening the cycle is stabilizing total spending (MV = PY), not stabilizing the price level per se.

The right policy is to stabilize aggregate demand (total spending PY) while letting the price level fall when productivity improves and rise when it falls, because an improvement in productivity is a change in the relative price of output to input—so forcing a stable output price level requires inflating input prices, whereas letting output prices decline is better.

Central banking politicizes the money supply, creating circumstances where competing interest groups (such as debtors who benefit from inflation) lobby for inflation or deflation; once money is politicized it becomes harder to return to a neutral system because beneficiaries resist losing their favors.

During the late-18th-century Industrial Revolution, the Royal Mint produced essentially no silver and almost no copper coins despite rapidly growing demand, creating a severe small-coin shortage that threatened industrialization by leaving industrialists unable to pay workers and merchants unable to make change.

Private coiners (such as Thomas Williams) issued copper coins that were initially heavier than Royal Mint equivalents, beautifully engraved to defeat counterfeiting, and redeemable on demand to balance supply and demand—producing money superior in all respects to the Royal Mint's and, via about 20 mints serving 200 issuers, solving the coin shortage.

The private coinage episode ended because issuers progressed to silver and finally a small amount of private gold coins, prompting the government and the threatened Royal Mint to declare private coinage illegal as an encroachment on the sovereign prerogative of coinage.

Gresham's law ('bad money drives out good') applies only where government has monopolized coinage and uses legal-tender laws to force inferior coins to circulate at par with superior ones; in a free market with no legal-tender laws merchants can price in or refuse bad coins, so the opposite prevails—good money drives out bad.

Legal-tender enforcement of debased money is a prisoner's dilemma whose equilibrium outcome is the circulation of bad money, as shown by French Revolution assignat laws that made it illegal for a merchant to ask which kind of money he would be paid before making a deal.

There has never been a country with perfectly complete free trade, yet free trade theory and models are what give economists their understanding of what tariffs do.

Most monetary economists, when they talk about central banks controlling money growth, literally don't know what they're talking about because they lack a conception of what a free banking system looks like.

Banking has long been a particularly heavily regulated industry even in otherwise capitalistic, free-market countries.
