The Bank for International Settlements’ (BIS) broad effective index is the gold standard for assessing exchange rates. And the BIS shows—building on a point that George Magnus has made—that China’s currency, measured against a basket of its trading partners, has depreciated significantly since last summer. And since the start of the year. On the BIS index, the yuan is now down around 7 percent YTD.
Those who were convinced that the broad yuan was significantly overvalued last summer liked to note how much China’s currency had appreciated since 2005.
But 2005 was the yuan’s long-term low. And the size of China’s current account surplus in 2006 and 2007 suggests that the yuan was significantly undervalued in 2005 (remember, currencies have an impact with a lag).
I prefer to go back to around 2000. The yuan is now up about 20 percent since then (since the of end of 2001 or early 2002 to be more precise).
And twenty percent over 15 years isn’t all that much, really.
Remember that over this time period China has seen enormous increases in productivity (WTO accession and all). China exported just over $200 billion in manufactures in 2000. By 2015, that was over $2 trillion. Its manufacturing surplus has gone from around $50 billion to around $900 billion. China’s global trade footprint has changed dramatically since 2000, and a country should appreciate in real terms during its “catch-up” phase.
