The Nordic Banking Crises

The Setup

Norway, Sweden, and Finland entered the 1980s with the most regulated banking systems in the capitalist world — lending ceilings, interest caps, and currency controls that had made banking a boring public utility for fifty years. Then, within a few years of each other, all three swept the controls away. Sweden’s “November revolution” of 1985 abolished lending ceilings overnight.

Banks that had spent decades rationing credit suddenly competed for market share, and the finance houses beside them competed harder. The natural outlet was property. And because all three currencies were pegged, banks and firms could fund the boom in cheaper deutschmarks and dollars — FX risk was somebody else’s problem, later.

Freed banks competed on volume, property collateral validated every loan, and pegged currencies made foreign borrowing look riskless — the same loop, in triplicate, in Oslo, Stockholm, and Helsinki.

Credit-to-GDP ratios jumped by a third in five years. Helsinki, riding Soviet trade and a casino stock market, ran hottest of all.

Displacement, 1985–87

Deregulation is the sensible modernization everyone recommended. But fifty years of pent-up borrowing demand meets bankers with no living memory of a credit loss — the most dangerous combination the book knows.

Boom, 1988–89

Property and shares double together. Real after-tax interest rates are negative — generous deductions meet high inflation — so borrowing is literally being paid to borrow.

Euphoria, 1989–90

Commercial rents price in a future that arithmetic can’t deliver; Finnish conglomerates leverage into each other’s shares. The Stockholm index peaks in August 1989, months before anyone admits the party is over.

Distress, 1990–91

The finance houses go first — Nyckeln’s September 1990 collapse freezes the commercial-paper market that funded them. Property stops selling; German reunification pushes European rates up just as the pegs demand they be defended.

Panic, 1991–93

Sweden’s share index gives back −49% peak to trough while banks’ property books implode; Finland loses over a tenth of GDP. The Riksbank briefly sets its marginal rate at 500% in September 1992 to defend the krona, then lets it float in November. Two of the three countries end up owning most of their banking systems.

The Nordic resolution became the modern textbook: act fast, guarantee broadly, nationalize honestly, park the wreckage in bad banks — Sweden’s Securum — and sell it off in daylight. Swedish taxpayers were largely made whole once the bad banks had sold down; Finnish taxpayers were not, and Finland’s bill net of asset sales still came to around 5% of GDP. 2008’s crisis managers studied Stockholm openly. The book files the episode under its most reliable rule: financial liberalization, wherever it arrives, is followed within a decade by a credit boom and a banking crisis — even in economies famous for good government.

What it cost

Deregulation’s bill came due mostly in unemployment, not on a single crash day. Finnish unemployment quadrupled between 1990 and 1993, from 3.5% to 16.5%, on Gorodnichenko, Mendoza and Tesar’s figures; Sweden’s went from around 2% to over 8%, on Jonung’s. Finland’s suicide rate did not follow the same curve: Statistics Finland records its peak in 1990, before the worst of the slump, and a decline through the recession years that came after.

Until 1993 Finland had no way for a court to write down what a private person owed. On 25 January that year, at the bottom of the slump, it enacted the Act on the Adjustment of the Debts of a Private Individual — passed, Kinnunen writes, to help people with serious debt problems following the depression. District courts took 10,285 applications in the first year and 14,003 in 1995, still the busiest year on record; more than 72,000 arrived in the Act’s first decade, against roughly 4,000 a year now. Around 100,000 Finns have had debts adjusted under it.

What followed

Both electorates turned once the acute crisis had passed. Sweden’s centre-right coalition under Carl Bildt, which had defended the krona and taken the failed banks into public hands, lost the election in the autumn of 1994 immediately after the crisis, Jonung writes, ceding power to the Social Democrats. Finland swung the same way the following year: the Centre Party, which had topped the poll in 1991 as the slump deepened, fell from 24.8% of the vote to 19.8% in 1995, while the Social Democrats rose from 22.1% to 28.3%.
