The five domino chains behind most crises and recoveries

Financial crises look like lightning — sudden, unforecastable, each one unique. They are closer to weather fronts. A small set of causal chains, running through the same four forces, produces most of the storms and most of the recoveries. The four forces:

• credit (how willingly lenders lend)
• liquidity (how much money is moving through the financial system)
• growth (whether the real economy is expanding)
• the dollar (the currency most of the world borrows and trades in)

The triggers differ every time. The order in which the dominoes fall does not. What follows traces the five chains step by step, each with its reference case — not because these are the only possible sequences, but because a reader who holds these five can decompose most financial history, and most financial headlines, into mechanism rather than mystery.

Chain one — the tightening spiral

Lenders turn cautious, or a central bank raises the price of money. The weakest borrowers must now refinance at worse terms, so the extra yield risky borrowers pay over governments — the credit spread — starts to widen.

Wider spreads make investment projects uneconomic; companies slow hiring and spending; earnings estimates fall; risk assets reprice downward; falling asset prices make lenders more cautious still. The spiral feeds itself.

The first domino is the quietest. Adrian and Boyarchenko showed that financial conditions predict not the average of future growth but its bad tail — the worst plausible outcome fattens while the consensus forecast barely moves.

In practice: a widening of roughly a third of a percentage point in investment-grade spreads over a few weeks, with no obvious news, is the earliest survivable warning. In 2006–2007 that signal blinked for over a year while growth forecasts stayed benign.

Chain two — the recovery arc

The spiral produces panic; panic produces a policy response. The central bank cuts rates, and in severe cases directly backstops markets that have frozen.

Liquidity expands while sentiment is still fearful. Risk assets bottom and turn up before the economy improves — which is why waiting for good news guarantees missing the recovery — and credit, equities, then employment heal in that order.

March 2020 is the reference case, and it carries the chain’s key diagnostic: the cure must match the disease. That crash was a funding freeze — markets seizing up for cash — which is exactly what a central bank can fix, because it can create cash without limit. When the backstop reached credit markets directly, the arc was underway within weeks.

The balance-sheet recession

The chain has a failure condition, and Japan after 1990 is its proof. In a balance-sheet recession — Koo’s term for a slump in which households and firms are so over-indebted that they repay debt at any price of money — rate cuts reach zero and nothing reignites. Money is created but not borrowed; the transmission fails; equities took decades to recover in nominal terms and never did in real terms.

The recovery arc is conditional, not guaranteed, and the condition is whether anyone still wants to borrow.

Chain three — the inflation trap

Inflation rises far enough that the central bank is forced to tighten even as growth weakens — the one configuration in which policy cannot rescue markets, because rescuing them would feed the inflation. Rates rise; the present value of distant cash flows falls; and here is the step most investors never see coming: bonds and equities fall together, because both are claims on faraway money. A share is the discounted value of decades of future earnings — functionally a long-dated bond wearing a different costume.

The usually negative stock-bond correlation flips positive, and the classic 60/40 portfolio loses on both legs at once. In 2022 a balanced portfolio of that shape lost roughly 16% — one of its worst years on record — with no banking crisis and no recession headline to blame. The hedge became the hazard, and an entire generation of allocators was surprised because their whole investing lives had shown only the friendly correlation.

Chain four — the reserve drain

A country pegs or manages its currency while borrowing heavily in dollars. The dollar strengthens; servicing the debt gets harder; the country spends its foreign-exchange reserves — its emergency dollar savings — defending the currency. When reserves run low, the defence fails, the currency breaks, foreign capital flees, dollar debts become unpayable overnight, and defaults cascade into the banking system and the real economy.

The 1997 Asian crisis is the reference case, and it teaches the chain’s signature: the order of visibility.

• The currency market cracks first — it is the deepest, fastest market.
• Equities reprice weeks later as foreign capital exits.
• The real economy — defaults, bank failures, recession — grinds through last, months behind.

A fixed exchange rate is a promise backed by finite reserves; when the reserves are gone, the promise breaks violently, never gently.

Chain five — the dollar cascade

The dollar is not merely a currency; it is the world’s funding currency — the money most cross-border debt is written in. When the dollar surges, every borrower of dollars everywhere is squeezed simultaneously: their debts grow in local terms while their revenues do not. The result is a global, synchronised tightening that no single country chose.

The cascade has a recognisable ordering: the most fragile, most speculative assets crack first. Emerging-market currencies, crypto, and the riskiest credit fall before major equity markets do — and that ordering is itself the confirmation that a genuine global tightening is underway rather than a local accident. In 2022, crypto — marketed through the prior summer as an uncorrelated diversifier — fell by more than half alongside technology stocks, because both were the same bet on abundant liquidity wearing two costumes.

How the chains interlock

Two connections matter more than any single chain. First, one chain’s rescue seeds the next chain’s crisis: the unprecedented liquidity flood that reversed the 2020 crash became the monetary fuel for the 2022 inflation trap. The correct question about any rescue is what it will cost two years later.

Second, every chain that ends in recovery silently assumes the central bank still has room to act. The long-term debt cycle framework holds that this room decays as debt accumulates across decades of short cycles — and Japan is the recorded case of a chain-two engine with the recovery mechanism effectively unplugged. The chains are a reliable grammar within a monetary era; whether the era itself persists is a separate and harder question.

The limitation

The chains are a grammar, not a timetable.

They say what order the dominoes fall in, never on what date; more than one chain can run at once (2022 was chains three and five interleaved); and which chain is truly active is often settled only in hindsight. Anyone narrating a live crisis with total confidence about which chain it is has confused a map with a forecast.

The working test, from here on: take any financial headline — a rate decision, a currency wobble, a credit downgrade — and ask which domino is this, in which chain? Most of the time there is an answer, and finding it converts news from noise into position on a map.

What the chains do not say is how fast the dominoes fall. That is the next chapter.
