AS the world debates whether  the renminbi (RMB) is undervalued, the real concern is whether after the  RMB revalues, China will repeat the mistakes of Japan during the 1985  post-Plaza Accord period.
In that decade, the yen rose from  roughly 240 yen to one US dollar to as low as 80 by August 1995 and then  depreciated to 147 in June 1998 before joint intervention stopped the  depreciation worsening the Asian crisis.
During this period,  Japan suffered the worst asset bubble with the stock market falling by  more than 80%, land prices falling by over 60% and the banking crisis  took nearly a decade before it was finally resolved.
The Japanese  public debt rose to nearly 200% of GDP, one of the highest in the OECD  countries and Japan had almost zero growth for nearly two decades, as  interest rates were kept near zero.
The worst part of the  Japanese dilemma is that with a huge overhang of the public debt and an  aging population, Japan may face both a decline in population and also  an implosion in the wealth holdings if interest rates were to go back to  global levels.
Note that unlike the US, which has a lot of  foreign debt owed in US dollars, the high level of Japanese debt is yen  debt owed to its own citizens.
There are many foreign  commentators who think that after the recent increase in credit in the  Chinese banking system, equivalent to nearly 40% of GDP, with a broad  money to GDP ratio of 180% of GDP, that China may be facing a  Japanese-style meltdown.
What is the truth and what is the  correct analysis?
In the period 1950-70, Japan enjoyed high  growth, high capital formation, rapid monetization and rising property  prices, very similar to what China is going through.
The  interesting point is that monetization did not appear to be highly  inflationary, so in the run-up to 1989 at the height of the asset  bubble, the Bank of Japan was initially reluctant to raise interest  rates.
Exactly like what happened with the US subprime bubble,  there was also insufficient regulatory action to stop banks exposing  themselves to real estate loans. Koyo Ozeki is Japan analyst for PIMCO  and his analysis in December 2009 is very illuminating (www.pimco.com).
The amount of bank lending equivalent to nearly 40% of GDP also went  into Japanese real estate between 1985 to mid-1990s.
In the case  of Japan, most of it went into commercial real estate. Real  estate loans to individuals for mortgages only accounted for 20% of the  total credit growth.
What was interesting was his comparison of  Japan (1985-91), US (2000-2007) and China (2003-2009).
During  these periods, Japan and US grew roughly by 3% per annum, whereas China  grew by 10%.
Real estate bubbles during this period were roughly 2  times in price growth for China and the US, but 5 times in the case of  Japan.
He felt that since in China “there is overwhelming shortage  of residential property that meets its new living standards; it will  likely take a considerable amount of time for supply to catch up to  demand.”
He “sees little risk in the foreseeable future that  increase in loans to the real estate sector will pose a threat to the  financial system”, but also recognizes that “a rapid increase in lending  could lead to a rise in bad debt in the future.”
What were the  Japanese policy mistakes during the bubble period and what can we learn  from this?
One of the most distinctive features of the Japanese  experience was how long it took to bring the banking crisis under  control.
It was almost eight years after the bubble burst in 1989  before the first serious failures of banks forced the government to use  public funds to prevent the meltdown in the banking system.
Hiroshi  Nakaso, formerly from the Bank of Japan, wrote probably the best  technical analysis of this experience for a paper for BIS in 2001.
Part  of the problem was that no one understood the scale of the losses  because there was a paradigm shift.
Richard Koo, the chief  economist of Nomura Securities, called this a “balance sheet deflation”.
No one understood how serious the real estate bubble had on the  balance sheet of the banking system.
I have argued that the real  estate bubble is the elephant in the room – no single government  department is in charge and current fragmented monetary and regulatory  theory grossly underestimates the importance of real estate as  collateral for companies and bank loans, income for local governments  and wealth of households.
So when the real estate bubble burst,  the damage to household, corporate, government and bank balance sheets  is huge, but the effects may take a while to recognize in accounting  terms.
Ozeki (2008) noted that it took the Japanese government a  long time to recognize the asset deflation because most people assumed  that the property prices would turn around after such low interest  rates.
Secondly, the Japanese banks had large latent profits from  their holdings of corporate shares that everyone assumed that they  could cushion themselves from the asset losses. But the more the banks  sold the shares, the lower the stock market prices became, creating a  downward spiral in confidence and growth.
Thirdly, the cumulative  bad debt problems were as large as 25-30% of GDP, in addition to actual  write-offs amounting to 20% of GDP.
No one has an accurate  number on the massive deflation of the Japanese real estate bubble.
Assuming  that the US real estate/GDP ratio of 225% of GDP was the ratio for  Japan in 1989 and prices deflated by 60%, then the wealth loss could be  as high as 130% of GDP.  Because these were commercial real estate, most  of the losses were borne by the corporations, and those who could not  finance their losses transferred it to bad debt for banks.
Given  the fact that the banks had capital not more than 10% of GDP, it was not  surprising that the Japanese banking system could not by themselves get  out of the bad debt burden without large fiscal help.
Most  analysts identify the new credit in China as being given to local  government financing vehicles. This is the topic that I shall discuss in  the next article.
