China's $88bn monthly surplus, three times the pre-pandemic norm, is funding infrastructure and green tech investment. The real payoff is a rising role for the renminbi.
China’s average monthly trade surplus has reached US$88 billion so far in 2026, roughly three times the US$32 billion average recorded in the 2018–19 period, according to Westpac Economics. Even after slipping from last year’s US$99 billion monthly pace, the surplus is fundamentally reshaping where and how China invests–and, ultimately, how the world uses the renminbi.
This week, President Xi Jinping and President Donald Trump are scheduled to meet. The conversation will touch on bilateral relations, the global economy, and likely the Middle East conflict. It will not materially alter the status quo–officials have described it as one of several planned meetings–but it will guide the market’s understanding of the opportunities and risks in China’s outward-facing growth model.
China’s goods surplus last decade averaged a little over US$32 billion a month. In 2025 that figure jumped to US$99 billion, and through the first months of 2026 it is holding at US$88 billion. The step change is not noise. It reflects an export engine that has broadened well beyond low-cost assembly to encompass machinery, electric vehicles, refined energy products and componentry that feed into the world’s green transition.
The US trade position has moved in the opposite direction. An average monthly deficit of US$47 billion in 2018–19 has widened to US$73 billion in 2025–26. Admittedly, the US data pre-dates the surge in energy exports seen in April and May. China also temporarily pulled back on energy goods supplied to other nations, trimming its own export revenue. But the direction is unambiguous: one economy systematically generates surpluses while the other systematically deepens its deficit.
For currency markets, the superficial take is straightforward–a large, persistent surplus should strengthen the currency. The real story, however, lies in what China does with those surplus dollars, and how that activity changes the structural demand for the renminbi over a multi-year horizon. forex market analysis
Instead of simply accumulating reserves, Chinese fixed asset investment continues to climb. The most recent data shows a sharp acceleration in transport- and storage-related infrastructure spending in early‑2026. Utilities investment has compounded at roughly 9% year‑to‑date, extending a run that began during the heavy industrial push of 2020–2025.
Within manufacturing, the subsectors that matter most for trade are beginning to stabilise and turn up. Electrical machinery, automobiles (dominated by electric-vehicle capacity) and chemicals all posted evidence of a trough in the first quarter. That matters because each of these industries is tightly linked to the global demand shock triggered by elevated energy prices and persistent uncertainty over Middle East supply. As we noted in a separate piece on China’s auto sector, booming EV exports are offsetting a collapse in domestic car sales, but the broader point is that the surplus is being recycled straight into the physical assets that will produce the next generation of exports.

Crucially, China’s capital deployment does not face the same hurdle-rate calculus as US for‑profit entities. State-owned and state-linked enterprises can commit multi-year investment without the same sensitivity to tariff uncertainty or elevated long-term interest rates. That subsidy of certainty is a quiet competitive advantage.
Across the Pacific, the investment picture could hardly be more different. US fixed investment remains highly concentrated in artificial-intelligence infrastructure–data centres, chips, and the software stack that surrounds them. Spending on areas related to trade, transport, and the domestic real economy is noticeably weak.
Three forces are at work. First, lingering uncertainty about tariff policy makes companies hesitant to commit capital to cross-border supply chains. Second, long-term yields have stayed elevated, raising the discount rate applied to capital-intensive projects. Third, and perhaps most important, the return profile on AI investment, while uncertain, is perceived as more manageable than the return on traditional industrial capacity in an environment where the US has explicitly signalled a desire to reshore production but not yet provided the policy stability to make reshoring pay off.
The gap between China’s deliberate, state‑backed investment in real productive capacity and the United States’ narrow, technology‑focused outlay is not a one‑quarter story. It is the backdrop against which the long‑term relative value of the two currencies should be assessed.
While Washington was threatening to pull US troops from Germany and proposing a 10‑percentage‑point increase in tariffs on European cars and trucks–alleging that the EU failed to hold up its side of a trade deal–Beijing was methodically tightening its commercial ties with the continent.
The EU publicly labelled the US an “unreliable” trading partner and vowed to respond. Behind the scenes, Chinese authorities were already hosting a series of high‑profile visits from European leaders and were encouraging Chinese firms to invest inside Europe while signalling that European companies would find a receptive home in China. The Westpac report characterises the emerging relationship as “an integrated, mutually-beneficial trade relationship taking shape between China and Europe.”
This is more than diplomatic theatre. If the eurozone, facing fresh US friction, reorients a larger share of its supply chains toward China, two things happen. First, the volume of trade settled in renminbi–already rising in bilateral commodity and machinery deals–climbs further. Second, European corporates’ need to hedge and fund in renminbi deepens the offshore RMB liquidity pool. Both developments provide a natural bid for the currency.
The final piece of the transmission chain is the geographical breadth of China’s investment. The Westpac analysis emphasises that capital is not concentrated in any single jurisdiction. It is spreading across Asia, Latin America, and Africa, targeting not just the assembly of finished goods but the production of supply inputs–raw materials, refined energy, high‑tech components.
Over time, that footprint produces a self‑reinforcing cycle. Resource exporters, component suppliers, and host-country partners are increasingly willing to invoice in renminbi because they will need RMB to purchase Chinese capital goods or service Chinese‑funded debt. As more trade pivots to renminbi settlement, the demand for onshore financial assets increases. That, in turn, accelerates the development of China’s bond and equity markets, making it feasible for authorities to offer renminbi‑denominated instruments to global investors and to Chinese savers seeking overseas exposure within the same currency.
The Westpac note summarises it plainly: “The larger these flows become, the greater the opportunity for Chinese banks and financial entities to facilitate flows, provide capital and manage risk, both on and, more importantly, offshore.” For the foreign‑exchange market, this means the renminbi’s liquidity profile, institutional support, and role as a funding currency will all expand–creating a long‑term structural tailwind that a simple trade‑weighted analysis of the surplus would miss.
None of this is an overnight trade. The Xi‑Trump meeting this week will probably generate headlines, but it will not interrupt the multi‑year investment trend that is turning China’s surplus into a global financial architecture. The next concrete tracker is whether the EU makes good on its promise to respond to US tariff threats, and how quickly China and Europe formalise their deepening alignment. Until that changes, the yuan’s international journey is firmly pointed in one direction.
