Global imbalances are back at the top of the international finance agenda. They drove a flagship G7 report this year and produced open discord at the G20 finance ministers’ summit. On the surface, the alarm looks justified. China’s goods trade surplus now worries European leaders as much as American ones, and the United States’ net liability to the rest of the world — the amount its overseas borrowing exceeds its overseas investment — hit roughly 70 percent of GDP in 2025. US Bureau of Economic Analysis data put the net international investment position at close to minus $27.6 trillion by the third quarter of the year, the deepest deficit on record and more than double the figure from just five years earlier. The last time imbalances drew this much attention was in the run-up to the 2008 financial crisis.
The trouble is that this focus is largely misdirected. Imbalances aren’t a flaw in the global financial system — they’re a feature of it. They come from ordinary saving and investment decisions made inside individual countries and help spread risk more widely. A “global imbalance” is really just the sum of everyone’s domestic imbalances, given a misleadingly international name.
Why Imbalances Aren’t Inherently Dangerous
Because foreign capital moves more easily than domestic capital, it tends to punish bad policy by leaving. That’s a feature, not a bug: it disciplines governments that would otherwise borrow and spend without consequence.
Take the US case. A 70-percent-of-GDP net liability sounds alarming, but two facts explain it: the US issues the world’s principal reserve asset, the Treasury bond, which central banks and investors everywhere hold; and its AI-driven investment boom has generated more attractive opportunities than domestic saving alone can fund, so foreign capital fills the gap.
Far from a “wealth transfer” out of America, this is standard risk-sharing working as intended. Non-Americans diversify out of slower home assets into high-performing US ones; Americans don’t have to shoulder all the investment risk alone. Everyone benefits — in theory.
Sharing Risk Isn’t the Same as Eliminating It
Openness has a cost. Foreign investors are “flightier” than domestic ones — they lack home bias and may doubt how well local law protects their money if things sour. That means capital can leave fast when confidence drops.
Does that set up a repeat of 2008? Probably not. That crisis came from lax financial regulation, not a “global savings glut.” And the US position has a built-in stabiliser: its liabilities are priced in dollars, while much of its foreign assets sit in other currencies. If investors pull back and the dollar weakens, the dollar value of those foreign assets rises, cushioning the overall position.
What the Imbalances Actually Reveal
Read closely, today’s imbalances are a diagnostic tool pointing at specific, well-known domestic failures.
The US government runs gross debt near 125 percent of GDP — larger than its entire external liability position — while rising Treasury yields push policymakers toward increasingly unconventional fiscal responses.
Europe isn’t generating enough investment of its own. Savings that might fund European growth instead flow toward US AI infrastructure, eroding competitiveness relative to both the US and China — a gap Mario Draghi’s 2024 report on European competitiveness put at roughly €800 billion a year.
China spends too little relative to what it produces. Savings get funnelled into investment at a scale that inflates asset bubbles rather than consumption, and after its property sector collapsed, exports surged while import demand stayed weak — frustrating trading partners well beyond the US.
In each case, the fix is domestically obvious. What’s missing is political will.
Diplomacy That Isn’t Delivering
Economist Hélène Rey has argued these separate national problems could be tackled together — US fiscal consolidation offset by rising European investment and Chinese consumption — making both the economics and politics of adjustment easier.
Recent diplomacy hasn’t delivered that. The G7 failed to agree on US fiscal consolidation or European structural reform, and punted the issue to the G20 finance ministers’ summit, which then failed to produce a joint communiqué at all. The resulting chair’s statement leaned noticeably harder on surplus countries than deficit ones, and Washington was open about blaming China for the breakdown.
That pattern — blaming external forces for internal choices — has real political appeal. It shows up in claims that imports “steal jobs,” in the notion that a reserve-currency issuer is somehow obligated to run deficits, and in blunt tools like tariffs that treat the symptom while leaving the saving-investment gap untouched.
The Bottom Line
Global imbalances aren’t an imminent crisis. They’re an early warning system for problems each country could fix at home. By dwelling on the global dimension instead of following through with real domestic reform, policymakers risk weakening the case for hard choices rather than strengthening it. The old, unfashionable line from the Washington Consensus still holds: prosperity comes from putting your own house in order, not blaming the neighbours for the state of your garden
