A look at China's debt-fueled growth figures shows we should be a lot less confident about the rest of the global economy and financial markets.
China engineered a 6.7 percent year-on-year growth rate in the first quarter the old-fashioned way: via a huge injection of credit. Borrowing increased at a stratospheric 58 percent annual rate in the first quarter, taking credit to a figure approaching nearly half of output in nominal terms.
That this money is going disproportionately into all the wrong areas — housing, manufacturing, infrastructure and state-owned companies — is a problem for China. Short term this has helped to stabilize Chinese markets and growth, but longer term it leaves China with more debt with which to reckon, more unneeded capacity to ultimately cut, and further away from its goal of an economy balanced more on domestic consumption and less on investment.
That China is going further down this road is also a problem for the rest of us. It is likely no coincidence that China's borrowing binge has come at the same time as a sharp recovery in global stocks and the price of oil.
On the broadest measure, nearly three times the credit was extended in China in March as in February. On a rolling annual basis it now takes more than five yuan of new credit to produce every yuan of new gross domestic product, more than when China opened the credit taps in 2009 to blunt the impact of the global downturn.
That rising ratio of new debt to new growth is a massive flashing red sign that the quality of investment, which wasn't high in the first place, is dropping. Investment and borrowing were particularly strong at state-owned companies, where efficiency is not, shall we say, a watchword.
China meets the "if something can't go on forever it won't" test. Certainly, China, with strong central control, has a lot more influence over how this plays out domestically than would be the case in Brazil or the U.S., but even on this there is a limit.
For the rest of the world, China's decision to use more debt as a lever has turned a strong headwind into a gently trailing breeze. Consider that the 6.7 percent clip of expansion in China, the world's second-largest economy, represents about a third of global growth of roughly 3.1 percent.
