The Sydney Morning Herald article you cite [1] measures “deposits”. The comparable figure in the United States is $12 trillion [2]. The comparison is misleading, however, since few U.S. institutions, financial or non-financial, “save” in deposit accounts. (This is true in a China, too.) All this comes down to the murky definition of “savings,” which are in the end largely irrelevant to national credit concerns since “credit” is trying to quality their probability of seizure (through default, expropriation or other means).
