Mercantilism and China's hunger for international reserves*

- Quantifies the contribution of the “mercantilist” motive to the reserve build-up in China during 1998Q4-2011Q4.
- Theory is consistent with using two vastly differing approaches to estimate the role of mercantilist reserve accumulation.
- In China's case, both approaches yield the same results.
- The main result suggests that mercantilism accounts for less than 10% of reserve accumulation.

This paper is motivated by the popular view that the surge in China's foreign exchange reserves is due to a distortionary exchange rate policy aimed at keeping the real exchange rate undervalued to support export-led growth. It undertakes an in-depth empirical investigation to quantify how much “mercantilist” and “precautionary” motives have contributed to the reserve build-up in China during 1998Q4-2011Q4. A substantial problem is that theory is consistent with employing two vastly differing approaches to defining and estimating the role of mercantilist reserve accumulation. A priori, either method could generate misleading results. The study shows, however, that the distinction between the two approaches is immaterial in China's case. The results suggest that mercantilism accounts for less than 10% of reserve accumulation. Precautionary motives and other factors seem to be the dominant determinants of the surge in China's international reserves.
