There is no single macro indicator with a better historical track record of leading global industrial cycles than China's credit impulse. Yet outside a handful of EM-focused desks, it is rarely referenced in mainstream commentary. That gap between predictive power and attention is exactly why we keep coming back to it.

What the credit impulse measures

The credit impulse is the change in the flow of new credit as a share of GDP. It is not the level of debt — China can carry an enormous debt stock indefinitely so long as the marginal lender (the state) remains willing. What matters is the second derivative: the acceleration or deceleration of new credit creation, because that flow is what funds new factory orders, new property starts, and new commodity purchases.

Historically, this measure has led global manufacturing PMIs by roughly nine to twelve months with a correlation that holds across multiple cycles. When Beijing turns the credit taps on, factories from Germany to South Korea see order books fill within three quarters. When it turns them off, global trade stalls within the same window.

The current turn

For most of 2024 and the first half of 2025, the credit impulse was deeply negative — Beijing was actively deleveraging the property sector and tolerating slower headline growth. Then, in stages, the policy mix shifted. Local government special bond quotas were expanded, the PBOC cut reserve requirements three times, and a meaningful infrastructure package was announced for 2026-2028.

The cumulative effect is a credit impulse that has swung from -3% of GDP to roughly +2% over twelve months — one of the sharpest reversals on record outside of full crisis-response episodes. That swing matters because it does not just stabilize Chinese demand; it actively accelerates it into the back half of 2026.

What this means for global PMIs

If history rhymes, global manufacturing PMIs should bottom in Q1 2026 and turn higher into Q2-Q3. The cleanest evidence will appear first in South Korean exports — Korea is the most upstream economy in the East Asian supply chain and produces the leading indicators (semiconductors, displays, machinery) that flow into Chinese factories. German industrial orders are the next confirmation point, followed by US ISM new orders.

Commodities

Copper is the trade. China consumes more than half of global copper supply, and the credit impulse moves copper demand with a lead-lag of about six months. The supply side is helpful too: Chilean and Peruvian production has been constrained by water rights and political risk, and the project pipeline for the next three years is the thinnest in two decades. We see a path to $5.50/lb in nominal copper prices on a 12-month horizon.

Iron ore is more complicated. Beijing's infrastructure push is steel-intensive, but the property sector remains a drag, and Beijing has explicitly signaled it will not bail out leveraged developers. Net-net we see iron ore range-bound — bullish demand, capped by structural property weakness.

Emerging markets

EM equities are the second-derivative play. When China's credit impulse turns positive, EM ex-China typically outperforms developed markets by 8-12% over the next twelve months. The mechanism is straightforward: stronger Chinese demand strengthens commodity exporters (Brazil, Indonesia, Chile), and stronger global PMIs lift export-heavy economies (Korea, Taiwan, Vietnam).

FX

The Australian dollar is the textbook trade. AUD has the highest correlation to Chinese fixed asset investment of any G10 currency. AUD/JPY also benefits from a second tailwind — the unwind of the yen carry trade as the BOJ continues its very gradual normalization.

The risks

Three things could invalidate this view. First, an escalation in US-China trade restrictions — particularly any move that disrupts the rare earths supply chain — would compress Chinese growth via the export channel even as domestic credit expands. Second, a property sector crisis larger than current expectations could absorb credit creation into balance sheet repair rather than productive investment. Third, geopolitical escalation around Taiwan would dwarf any cyclical signal.

None of those risks is zero. All of them deserve scenario weights. But the base case, based on the data we have today, is for a meaningful reflationary impulse to be exported from China into the global economy over the next four quarters. Position accordingly, hedge thoughtfully, and watch Korean export prints as your earliest confirmation signal.
