Remember, Japanese banks in general have 900% of their tangible assets invested in JGBs that are the most negatively convex instrument you can put into a portfolio. Assume for instance that a bank holds a 10 year bond yielding 80 basis points. A 100 basis point move will cost the JGB investor about 10 years of expected interest payments.
Think about the psychology of all the players and financial implications if rates do move 100 basis points. Think about the solvency of a nation which currently spends 50% of its central government tax revenues on debt service, half of which earns the lowest yields of any country in the world.
You can’t look at this as a simple question. You need to think about this as a multivariate equation. You have to think about the incentives and the fears of all the participants. And you need to think about the fiscal sustainability of the government.
I ran a survey of 1,009 Japanese investors where we asked: “If rates were to move up 100 basis points, would that engender more confidence and make you want to buy more JGBs?” or, “Would you take your money elsewhere, even if it were hamstringing your government’s ability to operate?” 8 – 9% of respondents that said that they would buy more bonds and almost 80% said they would run, not walk the other way.
In China, the big problem is the absolutely stunning growth of private domestic debt. According to a recent World Bank report, the total amount of credit in China has risen from 9 trillion dollars in 2008 to 23 trillion dollars today.
That increase is roughly equivalent to the entire U.S. commercial banking system.
