Time to Stop Forecasting China's Surplus Away¶
Source: Time to Stop Forecasting China's Surplus Away by Brad Setser (Council on Foreign Relations)
TL;DR¶
The IMF has systematically underestimated China's current account surplus — now close to 5% of GDP — driven by three structural factors: the property bubble burst widens the savings-investment gap, currency depreciation pushes the surplus higher, and persistently high savings rates (>40% of GDP) show no sign of abating. Setser argues the IMF's standard policy advice (monetary easing, fiscal consolidation, exchange rate flexibility) effectively encourages China to export its way out of domestic troubles. The global spillovers are significant: Chinese exports growing faster than global trade, deindustrialised Europe, and a China with greater supply chain control able to impose policy preferences. The standard recommendation of 0.5% GDP consumption support is woefully insufficient.
Three Structural Drivers¶
Setser identifies three deep-seated factors that make China's surplus persistent rather than cyclical:
1. Property Bubble Burst Widens the Savings-Investment Gap¶
The collapse of China's property sector — once a massive sink for domestic investment — has left a void. The savings that flowed into real estate construction now have fewer domestic investment destinations, widening the gap between what China saves and what it invests domestically. The result: excess savings spill out as exports.
2. Currency Depreciation Pushes the Surplus Higher¶
China's managed depreciation of the renminbi — partly a response to domestic economic weakness and partly a strategic export advantage — mechanically boosts the surplus in dollar terms. A weaker renminbi makes Chinese exports cheaper and imports more expensive, widening the trade balance.
3. Persistently High Savings Rate¶
China's gross savings rate remains above 40% of GDP — a structural feature of an economy with weak social safety nets, an ageing population (that saves for retirement), and limited consumption culture. This savings rate shows no meaningful sign of declining despite official efforts to boost consumption.
The IMF's Inadequate Framework¶
Setser is sharply critical of the IMF's treatment of China's surplus:
IMF policy advice — monetary easing, fiscal consolidation, exchange rate flexibility — effectively encourages China to export its way out of domestic troubles.
The IMF's standard playbook was designed for market economies with normal savings-investment dynamics. China's state-directed system responds differently: when told to stimulate domestic demand, China instead funnels credit to state-owned enterprises and export-oriented industries. The gap widens, not narrows.
Global Spillovers¶
Effect on Europe¶
The deindustrialisation of Europe is not an accident — it is a direct consequence of China's surplus-driven export machine. European manufacturing — from solar panels to EVs to steel — is being undercut by Chinese production capacity built with state-directed capital that does not need to earn market returns.
Effect on the United States¶
A world where China controls ever more of the global supply chain is not in the US interest — regardless of who occupies the White House. Setser argues that surplus-driven export expansion gives China leverage: countries dependent on Chinese supply chains are less willing to push back on Chinese policy preferences.
The Global Trading System¶
Chinese exports are growing faster than global trade itself — meaning China's share of world exports continues to rise. This is not the behaviour of an economy rebalancing toward domestic consumption; it is the behaviour of a mercantilist state using export surpluses to manage domestic economic contradictions.
Policy Recommendations¶
Setser argues that the standard recommendation — boosting consumption by 0.5% of GDP — is laughably inadequate given the scale of the surplus. What would be needed:
- Massive consumption stimulus — on the order of 3-5% of GDP, not 0.5%
- Structural social safety net reform — to reduce precautionary saving
- Exchange rate flexibility — genuine appreciation, not managed depreciation
- Reform of SOE dividend policy — so state-owned enterprises distribute earnings rather than reinvesting in excess capacity
None of these are politically feasible for the CCP, which is precisely Setser's point: the surplus is structural because it is political.
Key Takeaways¶
- China's surplus is 5% of GDP and persistent — not the cyclical blip the IMF keeps forecasting.
- Three structural drivers — property crash, currency depreciation, high savings — are mutually reinforcing.
- IMF advice is counterproductive — it encourages more export-led growth, not rebalancing.
- Global spillovers are real — European deindustrialisation and Chinese supply chain leverage are direct consequences.
- Standard prescriptions are insufficient — fixing the surplus requires politically unpalatable structural reform.
