#223 1991 · China State Council (triangular-debt clearance leading group, led by Zhu Rongji) · Public finance / enterprise debtupstream-solve
China's state enterprises owed each other money in circular chains too tangled to settle pair by pair, so the government seeded cash at a few points and forced it to cascade through the chain instead of mediating each debt separately.
the problem
a debt problem is really a connected chain of IOUs, but each firm only ever sees its own two neighbors
background
By 1991, Chinese state-owned enterprises were caught in a nationwide web of unpaid inter-company debt known as '三角债' (triangular debt): factory A owed factory B, which owed factory C, which owed a supplier further down the same chain, in loops with no clear start or end. By some estimates the total had grown to roughly a third of the entire banking system's outstanding credit, freezing production at plants that had built and shipped goods but still couldn't get paid, because the money owed to them was itself tied up several links further down the chain.
The intuitive fix is to mediate: bring two firms together, negotiate a settlement, move to the next pair. But every pairwise settlement only worked if the firm being paid could then use that money to pay whoever it owed in turn — and with thousands of enterprises and hundreds of billions of yuan involved, no negotiator could realistically trace, let alone coordinate, every chain link at once.
the move
Rather than mediate debts one pair at a time, the clearance campaign injected bank loans directly into a handful of enterprises sitting at the start of the most tangled chains — often power plants and other capital-project owners with large unpaid construction debts — with one rule attached: the cash had to be used quickly to pay down that firm's own debts to its suppliers, who were in turn required to pass it on the same way, cascading down the chain (a power plant repaying an equipment maker, who paid a steel mill, who paid a coal mine or railway) rather than sit as working capital. Some accounts of the campaign describe firms being allowed to keep a small share, reportedly up to 10 percent, of what they collected before passing the rest along within days. A pilot in China's northeast, the region with the most tangled debt chains, ran the approach for 26 days and cleared roughly ¥12.5 billion of arrears from that single push.
the payoff
Over 1991 and 1992, the campaign injected roughly ¥55.5 billion of funds, most of it bank loans, and cleared approximately ¥219 billion of overdue payments nationwide — each yuan injected clearing on the order of three to five yuan of debt as it cascaded down the chain, since a single injection could close several links at once. Combined with a similar earlier round in 1990 that cleared more than ¥160 billion, the campaigns together unwound hundreds of billions of yuan of frozen inter-enterprise debt across the early 1990s.
what came after
The 1991-92 triangular-debt clearance is remembered in Chinese economic history as one of the state's first large-scale attempts to treat a debt crisis as a network problem rather than a series of individual defaults, and the chain-repayment logic — inject at a point, force pass-through, let the network clear itself — is cited in later Chinese public-finance discussions of enterprise debt chains as the template for the difference between mediating disputes and unblocking a system.
