|Although the West likes to give economic pointers to China, China is sceptical of accepting advice [GALLO/GETTY]
The Chinese financial system's evolution in recent years has been extraordinary. I have observed its transformation as a member of the International Advisory Council of the China Banking Regulatory Commission (CBRC).
Back in 2002, all of China's major banks were awash in non-performing loans (NPLs), which in some cases amounted to more than ten per cent of the total balance sheet. None of the major banks met even the Basel I standards for capital adequacy.
Few financiers in London or New York could have named any bank other than Bank of China, which was often wrongly thought to be the central bank. And to suggest that the United States Federal Reserve, or the United Kingdom's Financial Services Authority, might have anything to learn from China's financial authorities would have been thought absurd.
Less than a decade later, much has changed. The old NPL problem was resolved, primarily by establishing asset-management companies to take over doubtful assets, and injecting new capital into the commercial banks.
Now, reported NPLs amount to little more than one per cent of assets. Foreign partners have been brought in to transfer skills, and minority shareholdings have been floated. Current valuations put four Chinese banks in the global top ten by market capitalisation. They are now expanding overseas, fortified by their strong capital backing.
Of course, challenges remain.
Even in China there is no magic potion that can revive a loan to a defunct exporter. And China's big banks have lent large sums, willingly or otherwise, to local governments for infrastructure projects - many of them of dubious economic value.
There is an ever-present risk that the property market might one day collapse, though banks would emerge in better shape than have banks in the US and the UK, because much speculative investment has been funded with cash, or with only modest leverage. The authorities in Beijing, especially the CBRC and the People's Bank of China (the real central bank), have a good record of managing incipient booms and busts, and I would not bet against their success this time.
They have considerable flexibility, owing to a range of policy tools, including variable capital and reserve requirements and direct controls on mortgage lending terms. They have already been tightening the screws on credit growth for several months, with positive effects.
It would be flattering to think that this turnaround in China's financial system been attributable to the wise counsels of foreign advisers. But, while external influences have been helpful in some ways - the stimulus of Basel I and II strengthened the hands of those in Beijing determined to clean up the banking system - the Chinese now, not unreasonably, treat advice from the City of London and Wall Street with some scepticism.
China setting an example for the West
For example, recent criticism of Asian regulators by US Treasury Secretary Timothy Geithner is viewed across the region with scorn, not to mention incredulity. A little more humility is in order, given US regulators' performance in the run-up to the crisis. People who live in glass houses should not throw even rhetorical stones.
The most interesting development is that we can now see increasing convergence in the regulatory philosophies and toolkits in Beijing, London, and New York.
Until the recent near-implosion of Western capitalism, the North Atlantic authorities thought that the end of financial history had been reached. Financial conditions could be controlled with one tool - the short-term interest rate - deployed exclusively in pursuit of a target, implicit or explicit, for consumer price inflation.
Banks' capital-adequacy ratios were set globally, and, once set, remained fixed. Otherwise, the market knew best.
Banks had their own incentives to lend wisely, and controls on lending would necessarily prove ineffective. By contrast, in China, all aspects of a bank's business were directly overseen. Indeed, most banks were under the sway of the central bank.
Now, in Beijing, officials see the advantages of a more hands-off approach, and of institutions with a primarily commercial focus. But they have not eschewed the use of variable capital and reserve requirements, loan-to-deposit ratios, and thresholds for minimum deposits and maximum leverage as controls on property lending.
Meanwhile, in developed capital markets, we are busily reinventing these "macroprudential instruments", to use the term now in vogue in Basel.
We can now see the utility of a more flexible toolkit to respond to excessive credit expansion, or asset-price bubbles, where the manipulation of short-term interest rates can be a blunt instrument or, worse, a double-edged sword. An interest-rate rise might take the heat out of the mortgage market, but it will also chill the rest of the economy.
Regulatory philosophies are converging, too. Former British Prime Minister Margaret Thatcher's famous injunction that "you cannot buck the market" was part of the regulatory mindset in the pre-crisis Anglosphere. And former Fed Chairman Alan Greenspan resisted any attempts to rein in the animal spirits of the wealth creators on Wall Street.
The Chinese were less ideological. They had no compunction about calling a bubble a bubble, or in intervening to deflate it. Now, only Sarah Palin reveres Thatcher's views on all issues, and Greenspan has been airbrushed out of financial history, Chinese-style.
When the G7 morphed into the G20 in early 2009, many were understandably worried that, with such a diverse range of participants, coming from such different traditions, it would be difficult to achieve consensus on regulatory matters in the Basel Committee and elsewhere. These concerns turned out to have been overstated.
The elements of a broader consensus on the future role of financial regulation are in place, as long as Americans such as Geithner can resist their constant desire to tell the rest of the world to do as they say, not as they do.
