China's super $1.2 tn surplus also tells us about unresolved contradictions in its economic model

Chinese customs data released on Wednesday show the country ended 2025 with a goods trade surplus of nearly $1.2 tn. The number is remarkable not only because it crossed a symbolic threshold, but also because it did so despite higher US tariffs, slowing global growth and deepening geopolitical fragmentation.

In manufactured goods alone, China's surplus now exceeds 10% of GDP and about 1% of global output, dwarfing historical peaks once reached by Japan or Germany. Even on broader current account measures, the surplus (about $650 bn, or 3.4% of GDP) appears moderate - only until one recalls that it's generated by the world's largest manufacturing giant, giving it economic and strategic consequences unlike any surplus before it.

China's surplus is not primarily an export story, but a savings-investment imbalance one. Trade surplus equals national savings minus domestic investment. China continues to save far more than it can profitably absorb at home. Household consumption remains depressed, hovering at about 38% of GDP, far below the 55-70% range typical of advanced and middle-income economies.


Precautionary savings remain elevated because of a weak social safety net, healthcare and old-age insecurity. Balance-sheet damage is inflicted by prolonged property collapse. At the same time, China's investment rate remains extraordinarily high, about 40% of GDP. But returns on that investment are declining sharply.

Demographic headwinds are intensifying as the working-age population has been shrinking, productivity growth has slowed as technological catch-up matures, and excess capacity has accumulated across housing, infrastructure and heavy industry. When an economy saves more than it can productively invest, residuals must flow outward. In China's case, exports have become the pressure valve that reconciles weak consumption with faltering domestic investment opportunities.

Then there's the resilience of Chinese exports in the face of Trump tariffs. Bilateral trade data show that tariffs did work in a narrow sense. China's exports to the US fell by about 20% in 2025, with December y-o-y declines exceeding 30%. Yet, total Chinese exports rose 5.5% for the year, and 6.6% in December alone. The explanation lies in distinction between bilateral exposure and system-level adjustment.

Chinese firms rerouted shipments aggressively toward third markets. Exports to Africa rose by more than 25%, to Asean by over 13%, and to the EU by 8-12%. Obviously, US final demand didn't disappear. It was increasingly satisfied indirectly through Southeast Asian assembly hubs and other intermediaries.

At the same time, Chinese firms accelerated establishment of overseas production facilities to arbitrage rules of origin and tariff regimes, while retaining upstream Chinese value-added. This has blurred line between 'Chinese exports' and 'foreign exports' without materially reducing China's industrial footprint.

Exchange rate and financial channels reinforced this adjustment. China's real effective exchange rate has depreciated materially since 2021, even after accounting for inflation differentials. Capital controls allow authorities to influence currency through state bank forex purchases that don't always appear on official reserve balance sheets. Combined with domestic deflationary pressures, this has preserved a significant competitiveness wedge for Chinese manufacturers.

Tariffs raised costs at the margin. Macro-financial policy offset them at scale. Directed credit continues to flow disproportionately into export-oriented and import-competing sectors, ensuring that capacity expansion and price competitiveness are maintained even under external pressure.

Sectorally, some of the strongest export growth came from capital-intensive and tech-embedded sectors. Auto exports rose nearly 20%, with EV shipments up close to 50%. Exports of ships, heavy machinery and semiconductors (particularly mature-node chips) grew by over 20%. By contrast, traditional labour-intensive sectors such as apparel, footwear and toys stagnated or contracted.

While the surplus is often described as a geopolitical weapon or mercantilist choice, it can be also seen better as a macroeconomic crutch. China faces a trilemma: chronically weak household consumption, declining returns to investment, and political resistance to large-scale welfare transfers that would permanently rebalance income toward households.

Exports allow the system to avoid resolving that trilemma. They sustain employment, absorb excess capacity and stabilise growth without forcing an explicit fiscal or social-policy pivot. But this creates what can be described as a trade-surplus trap. China becomes dependent on foreign demand to maintain internal stability. Domestic reform is postponed. Deflationary pressures persist. And external political resistance accumulates.

Spillovers are no longer confined to trade balances. China's dominance in strategically sensitive segments has introduced a national security dimension to what was once a purely economic debate. In 2024, China accounted for roughly 92% of global rare-earth processing. Export restrictions imposed in 2025 demonstrated how trade concentration can be weaponised, even defensively.

At the same time, the political economy effects abroad resemble a 'second China shock': not necessarily higher aggregate unemployment, but geographically concentrated industrial disruption that fuels protectionism and undermines support for open trade.

The irony is that China's record surplus looks like strength precisely because it masks weakness. As long as global demand remains resilient, the model can persist. But if Europe erects broader trade barriers, if fragile US-China tariff truce collapses, or if global growth slows sharply, China will be forced into adjustment it has delayed under far less favourable conditions.

China's $1.2 tn surplus is, therefore, not a puzzle to be admired but a signal to be interpreted. It tells us less about triumph of China's export machine than about unresolved contradictions at the core of its economic model, contradictions that the rest of the world is increasingly being asked to absorb.
