So that we can understand the financial and banking challenges ahead of us, this article provides an historical and technical background. But we must first get an important definition right, and that is the cause of the periodic cycle of boom and bust. The cycle of economic activity is not a trade or business cycle, but a credit cycle. It is caused by fractional reserve banking and by banks loaning money into existence. The effect on business is then observed but is not the underlying cause.
Modern banking has its roots in England’s Bank Charter Act of 1844, which led to the practice of loaning money into existence, commonly described as fractional reserve banking. Fractional reserve banking is defined as making loans and taking in customer deposits in quantities that are multiples of the bank’s own capital. Case law in the wake of the 1844 Act, having more regard to the status quo as established precedent than the fundamentals of property law, ruled that irregular deposits (deposits for safekeeping) were no different from a loan. Judge Lord Cottenham’s judgment in Foley v. Hill (1848) 2 HLC 28 is a judicial decision relating to the fundamental nature of a bank which held in effect that:
“The money placed in the custody of the banker is to all intents and purposes, the money of the banker, to do with it as he pleases. He is guilty of no breach of trust in employing it. He is not answerable to the principal if he puts it into jeopardy, if he engages in haphazardous speculation….”
This was undoubtedly the most important ruling of the last two centuries over money. Today, we know of nothing else other than legally confirmed fractional reserve banking. However, sound or honest banking with banks acting as custodians had existed in the centuries before the 1844 Act and any corruption of the custody status was regarded as fraudulent.
This decision has shaped global banking to this day. It created a fundamental flaw in the gold-backed sound money system, whereby the Bank of England, as a prototype central bank, could only issue extra sterling backed entirely by gold. Meanwhile, a commercial bank could loan money into existence, the drawdown of which created deposit balances. The creation of these deposits on a system-wide basis meant that any excesses and deficiencies between banks were easily reconciled through interbank lending.
Bankers’ groupthink and the credit cycle
While an individual bank could expand its balance sheet, the implications of all banks doing the same may have escaped the early banking pioneers operating under the 1844 act. Thus, when their balance sheets expanded to a multiple of the bank’s own capital, there was little cause for concern. After all, so long as a bank paid attention to its reputation it would always have access to the informal interbank market. And so long as it can call in its loans at short notice, the duration mismatch between funding by cash deposits and its loan book would be minimised.
Since the Bank Charter Act, experience has shown the expansion of bank credit leads to a cycle of credit expansion, over-expansion, and then sudden contraction. The scale of bank lending was determined by its management, with lenders tending to be as much influenced by their own crowd psychology as by a holistic view of risk. Of course, the expansion of bank credit inflates economic activity, spreading a warm feeling of improving economic prospects and feeding back into increasing the bankers’ confidence even further. It then appears safe and reasonable to take on yet more lending business without increasing the bank’s capital.
With profits rapidly increasing due to lending being a multiple of the bank’s own capital, confident bankers begin to think strategically. They reduce their lending margins to attract business they believe to be important to their bank’s long-term future, knowing they can expand credit further against a background of improving economic conditions to compensate for lower margins. They begin to protect margins by borrowing short from depositors and offering businesses term loans, reaping the benefits of a rising slope in the yield curve.
The availability of cheap finance encourages businesses in turn to enhance their profits by increasing the ratio of debt to equity in their businesses and by funding business expansion through debt. By now, a bank is likely to be raking in net interest on loan business amounting to eight or ten times its own capital. This means that an interest margin of a net two per cent is a 20% return to the bank’s shareholders.
There is nothing like profitable success to boost confidence, and the line between it and overconfidence is naturally fuzzed by hubris. The crowd psychology fuelled by a successful banking business leads to an availability of credit too great for decent borrowers to avail for themselves, so inevitably credit expansion becomes a financing opportunity for poorly thought out loan propositions.
Having oversupplied the market with credit, banks begin to expand their interests in other directions. They finance businesses abroad, oblivious to the fact that they have less control over collateral and legal redress generally. They expand by entering other lines of banking-related business, assuming their skills as bankers can be extended into those other business lines profitably. A near-contemporary example was Deutsche Bank’s failed expansion into global investment banking and principal trading in foreign securities and commodities. And who can forget Royal Bank of Scotland’s bid for ABN-Amro, just as the credit cycle peaked before the last credit crisis.
At the time when their balance sheets have expanded to many multiples of their own capital, the banking crowd then finds itself with lending margins too low to compensate for risk. Bad debts arising from their more aggressive lending decisions begin to materialise. One bank beginning to draw in its horns, as it perceives it is out on a limb, can probably be weathered by the system. But other bankers will stop and think about their own risks, bearing in mind operational gearing works two ways.
It may be marked by an unexpected event, or just an apparent loss of bullish momentum. With bad debts beginning to have an impact, groupthink quickly takes bankers from being greedy for more business to fearful of it. Initially, banks stop offering circulating credit, the overdraft facility that lubricates business activity. But former lending decisions begin to be exposed as bad when the credit tap is turned off and investments in foreign lands begin to reflect their true risks. Lending in the interbank market dries up for the banks with poor or marginal reputations, and banks begin to report losses. Greed turns rapidly to fear.
The cycle of bank credit expansion then descends into a lending crisis with increasing numbers of banks exposed as having taken on bad loans and becoming insolvent. A slump in business activity ensues. With frightening rapidity, all the hope and hype created by monetary expansion is destroyed by its contraction.
Before central banking evolved into acting as the representative and regulator for licensed banks, the credit cycle described above threw up some classic examples. Overend Gurney was the largest discount house in the world, trading in bills of exchange before it made long-term investments and became illiquid. When the railway boom faltered in 1866 it collapsed. Bank rate rose to 10% and there were widespread failures. Then there was the Baring crisis in 1890. Poor investments in Argentina led to the bank’s near bankruptcy. The Argentine economy slumped, as did the Brazilian which had its own credit bubble. This time, a consortium of other banks rescued Barings. Nathan Rothschild remarked that if Barings hadn’t been rescued the entire banking system in London would have collapsed.
Out of Barings came the action of a central bank acting as lender of last resort, famously foreseen and promoted by Walter Bagehot.
In the nineteenth century it became clear that crowd psychology in the banks, the balance of greed and fear over lending, drove a repeating cycle of credit boom and slump. With the passage of time bankers recovering their poise from the previous slump forgot its lessons and rhymed the same mistakes all over again. Analysts promoting theories of stock market cycles and cycles of economic activity need look no further for the underlying cause.
In the absence of credit expansion, businesses would come and go in random fashion. The coordinated expansion of credit changed that, with businesses being bunched into being created at the same time, and then all failing at the same time. The process of creative destruction went from unnoticed market evolution to becoming a periodic violent event. Monetary institutions still ignore the benefits of events being random. Instead they double down, coordinating their interventions on a global scale with the inevitable consequence of making the credit cycle even more pronounced.
It is a huge mistake to call this repeating cycle a business cycle. It implies it is down to the failure of free markets, of capitalism, when in fact it is entirely due to monetary and credit inflation licensed and promoted by governments and central banks...
