Credit is in the news again this morning, and this time they are asking “is the era of cheap credit over?”
The last few days have seen a raft of reports on this theme, and last night Bank of England monetary policy committee member, Paul Tucker, not to mention executive director for markets at the Bank, was scratching his head at the Institutional Money Market Funds Association annual dinner, and talked about a “serious puzzle.”
“There remains a risk,” he said, “that credit creation – the lubricant that the financial system provides to the real economy – will be further impaired.”
Time was of course that banks lent the money their depositors placed with them. Mr Cash-rich put his money in his bank, and the bank in turn lent that money to Mr and Mrs Lots of ideas for creating wealth but not much cash.
The rate of interest was set by the demand and supply of money. Banks needed to offer a sufficiently high interest rate to attract depositors. They then made a mark up on this, and re-lent the money to businesses or consumers. That mechanism is what used to form the market rate of interest.
Central banks, on the other hand, are the lenders of last resort. The rate of interest set by the Fed or Bank of England, for example, is set by different criteria.
Arguablly, in an environment of developing technology, where productivity is rising fast, central banks themselves need to lend to banks in order to facilitate a greater supply of money to match the new level of potential wealth the advances in technology have brought.
But for many years now, perhaps since Mrs Thatcher was Prime Minister and Ronald Reagan was President in the US, the credit markets have become far more complex. Banks have borrowed from each other. And as one bank lends to another, the credit provided itself becomes an asset. It can then borrow money, using its assets, which itself might be money lent to other banks as its capital.
More recently, money has flowed in from abroad, from countries like Japan, where the rate of interest was very low, and no decent return was available to savers; OPEC countries, where oil revenue created excess savings; and China, where excess savings led to massive balance of payments surplus, meaning the coffers at Chinese banks were overflowing with money.
Put all this together and you can see why the money markets had so much credit. As a result of this, at times the rate of interest set by markets was actually lower than the rate set by central banks. Alan Greenspan called this a conundrum, but the real cause was the massive flows of money from abroad.
But now it has all changed. Clearly US subprime has a lot to do with all this, but we are not so sure that is the only explanation.
Returning to Mr Tucker and his speech yesterday, he said, “Financial markets have swung from a prolonged period of underpricing risk to now plausibly overpricing risk on at least some products.”
He went on to say, “Banks around the world are carrying portfolios of term loans that are the legacy of the boom years. There is uncertainty – amongst banks’ management, shareholders and funders – about the degree of fundamental impairment in those portfolios. New loans are booked to the same balance sheets. And so many banks face a choice between, on the one hand, conserving capital and liquidity to support legacy portfolios; and, on the other hand, deploying capital and liquidity to write new business on what some see as the attractive terms and conditions now available.”
So the assets sitting in banks’ electronic vaults are not worth as much as they were. As a result, banks have become reluctant to lend to each other, or to take on more debt.
But, as the dollar falls, and with expectations that sterling will fall too, one assumes overseas lenders are becoming reluctant to put their cash on the Western money markets too.
Then we come to house prices. If house prices continue to fall in the US, and start to fall in the UK, then it seems likely individual insolvency levels will rise, leading to more losses at banks, and a further tightening in credit.
As a result of all this, at the moment it seems to be almost irrelevant what the central banks do. Sure, the Fed has slashed rates, the Bank of England has started lowering rates, but the banks need more savers, and to attract them, they need to offer higher interest rates, and in turn need to make more money on the money they lend out.
It seems that the rate of interest set by demand and the supply of money, has deviated from the rates set by central banks.
Mr Tucker said, “For well over a century, throughout industrialised world there has in effect been something akin to a Social Contract between the banking system and the authorities. The banking system is permitted to profit from undertaking leveraged maturity transformation in the course of intermediating the liquid savings of depositors into illiquid loans to households, firms and others. In doing so, commercial banks provide liquidity insurance, whether via demand deposits or committed lines of credit. They can do this because their deposit liabilities are money, which puts them at the heart of the payments system and is what makes them special; banks are at the heart of a monetary economy. In return, the authorities respond with a combination of prudential supervision, to contain the risks that banks run; deposit insurance, to protect savers; and liquidity insurance from the central bank. ”
But over the last few years asset prices rose too high. Risk was wrongly priced. These mistakes are now being corrected, and the central banks think that playing with interest rates might get the economy rolling, but actually the true problem is far deeper than that.
