Adding the real total loans to the chart, we find a quite similar pattern to the Japanese case. The level of the real total loans in the first peak was high, but far lower than in the second peak. The last chart shows the figures for China (Chart 3). China has not yet peaked with respect to working-age population ratio, but it is close.
The property price index was taken from the web site of a Shanghai index provider, who unfortunately and unexpectedly shut down their site and vanished about a year ago (June 2011). I tentatively use this index since it has a longer span than other indexes, although I am not entirely sure how it was constructed.
