The Great
Rewiring

The standard account of British political economy between 1979 and 2008 is a story of two opposing projects. Margaret Thatcher's monetarist counter-revolution. Tony Blair's Third Way correction. They are usually told as antagonists.

Read mechanically, they are the same machine seen from two angles. The Conservative governments of 1979 to 1997 dismantled the institutional architecture of the post-war consensus — wage-bargaining inside nationalised monopolies, the lending cartel of the mutually-owned building societies, the regulated City of London. New Labour did not rebuild any of it. It inherited the financialised economy that resulted and built a fiscal compromise around it: capture the tax receipts of the City, recycle them into healthcare and education, and otherwise leave the wiring alone.

This report is the audit. The thesis is narrower than the usual political reading. Across three decades, the United Kingdom executed a single, continuous substitution: industrial wage income out, leveraged household asset income in. The 2008 crisis is the moment that substitution stopped working. The arithmetic of how it got there does not need ideology to explain it.

The Medium-Term Financial Strategy, introduced by Geoffrey Howe in 1980 and formalised by Nigel Lawson thereafter, was the operational doctrine. It rested on three propositions. Inflation is, in the long run, a monetary phenomenon. There is no stable trade-off between inflation and unemployment — only a "natural" rate determined by structural factors. The job of policy is therefore to commit publicly to declining nominal targets for the growth of sterling M3 (£M3) and for the PSBR as a share of GDP, and to credibly stick to them.

Credibility was bought at the front. The Bank of England's Minimum Lending Rate was raised to 17% in November 1979 — a post-war high. The transmission ran through three channels at once. Domestic demand was crushed by the cost of credit. The pound, supported by both high rates and the newly-arriving North Sea oil revenues, appreciated sharply in real terms. And on the supply side, the overvalued sterling acted as an unhedged competitiveness shock to every UK-made tradeable.

What followed was not a recession in the normal sense. Between 1980 and 1981 manufacturing output and capacity contracted by roughly 20%. Manufacturing employment fell by 1.5 million between 1979 and 1983 alone — more in four years than the sector had shed across the whole of the 1970s. National unemployment doubled from 5.4% in 1979 to 10.7% by 1982, and stayed in double digits until 1987.

Mass structural unemployment did the work that legislation alone could not. With workers more dependent on employers and less able to credibly threaten withdrawal of labour, the bargain shifted. A sequence of Employment Acts between 1980 and 1990 narrowed the legal grounds for industrial action, removed secondary picketing, made union officials liable for unlawful disputes, and required pre-strike ballots. The 1984–85 miners' strike, won by the state and lost by Arthur Scargill, was the public confirmation that the post-war counterparty had changed.

The numbers moved in lockstep. Trade union density fell from 52.4% in 1979 to 37.5% by 1989. The share of UK national income paid out in wages and salaries fell from 59.8% in 1980 to a post-war low of 52.4% by 1989, while the gross operating surplus of private corporations rose from 17.0% to 26.4% over the same period. Tax policy reinforced the direction: top marginal income tax rates were cut from 83% (60% with surtax abolition) to 40% by 1988, while the standard rate of VAT was raised from 8% to 15% in the first Howe budget of June 1979 — shifting the tax base from direct income to indirect consumption.

The original Thatcher privatisations of the early 1980s — Britoil, Cable & Wireless, Amersham, Jaguar — were modest asset divestments inside competitive markets. The decisive shift came in the second term. British Telecom was floated in November 1984. British Gas followed in December 1986. The ten regional water and sewerage authorities of England and Wales were privatised together in 1989. Electricity, divided into generation, transmission and supply, followed in 1990–91.

In each of the network cases, the government faced a choice. It could break the entity into competing units before sale — separate the wires from the supplier, the pipes from the gas marketer, generation from distribution — and accept lower flotation proceeds in exchange for structural competition. Or it could sell the firm whole, preserve its market power, and price the IPO to reflect that. Maximising the headline sale price won the argument in almost every case. British Telecom went to market as a single, vertically integrated incumbent. British Gas went as one. The regional water companies went as ten geographic monopolies. The structural reform was deferred indefinitely.

The price-cap regime then proved unable to fully recover what the sale design had given away. In electricity distribution and water, regulators repeatedly discovered ex post that allowed prices had been set too generously, and were forced to impose retrospective one-time cuts. The flotation revenue had been front-loaded. The regulatory under-performance was back-loaded onto consumers.

The pricing formula was further softened by pass-through variables that insulated firms from the structural risks of their sectors. British Gas was given RPI − X + Y, where Y passed wholesale gas costs straight through to retail tariffs. The regional water companies were given RPI − X + K, where the K-factor allowed the recovery of capital expenditure required to meet EU environmental and quality standards.

The combination — guaranteed cost recovery on capital expenditure, retained efficiency gains on operating costs, and a captive consumer base — turned the privatised water sector into a target for financial engineering. Through the 1990s and 2000s, regional water companies were acquired by private infrastructure funds, recapitalised with large quantities of debt, and used as a source of dividends. The structure transferred operational risk to consumers and equity returns to owners.

The political ambition of a "shareholding democracy" did not survive the float. The initial IPOs were oversubscribed by retail investors at deliberately discounted prices, but the small shareholders took profits within weeks. Share registers consolidated rapidly into institutional and, eventually, foreign hands. By the late 1990s, much of the privatised utility sector was owned by overseas pension funds, French and German utilities, and infrastructure vehicles based in tax-efficient jurisdictions.

The same year as Big Bang, with far less public attention, Parliament passed the Building Societies Act. The Act did to the mortgage market what 27 October had done to the securities market: it removed the walls that had separated it from the rest of finance.

Before 1986, UK home lending was dominated by mutually-owned building societies. They were governed by an effective cartel that maintained stable interest rates, restricted price competition between societies, and operated on a strict "quantity rationing" model: prospective borrowers built a savings history with a society, queued for a mortgage offer, and were lent a multiple of income within tight constraints. Residual surpluses were retained inside the mutual rather than distributed. Speculative use of depositor funds was legally precluded.

The Act dismantled this in three distinct ways. First, it permitted societies to fund themselves from wholesale money markets rather than relying solely on retail deposits, initially up to a 20% threshold, raised later to 50%. The constraint linking domestic mortgage supply to domestic savings was gone. UK mortgage lending could now be funded directly from international capital flows.

Second, in parallel, the major clearing banks — freed of the old qualitative credit controls — entered the home loan market in force. The cartel collapsed. Credit rationing was replaced by active price and volume competition. Loan-to-income multiples, loan-to-value ratios and product complexity all moved upward.

Third, the Act provided a statutory route by which a mutual could convert into a public limited company. Doing so unlocked the accumulated residual surplus of the society — historically locked inside the mutual structure — and distributed it as windfall shares or cash to current members. This created an explicit alignment of interest: management (whose pay and prestige would rise on conversion) and short-term opportunistic depositors known as "carpetbaggers" (who joined societies purely to vote for conversion) had every reason to push for demutualisation.

The Blair government took office on 1 May 1997 with a 179-seat majority and a different rhetoric. Its policy architecture, however, accepted every structural feature of the system it inherited: a deregulated City, a privatised utility sector, a converted building society sector, a market-based mortgage system. What it added was a fiscal compromise.

The credibility apparatus was built first. Five days into office, on 6 May 1997, Gordon Brown granted the Bank of England operational independence to set interest rates against a symmetric inflation target. The "Golden Rule" of public finance was announced: over the cycle, the government would borrow only to fund net capital investment, with current spending matched by tax revenue. And for the first two years, the new government held public expenditure inside the spending envelope inherited from Kenneth Clarke's last Conservative budget. The bond market, having been the proximate cause of the 1976 crisis, was reassured.

Once credibility was established and the global credit boom of the early 2000s began to deliver tax revenues from the City, the second half of the compromise was activated. Public spending on healthcare rose from 5.7% of GDP in 1997 to 10.0% by 2010 — real per capita NHS spending nearly doubled. Education spending rose from 1.6% to 5.7% of GDP over the same period. Capital was injected into hospital buildings, school estates, NHS IT systems, and university expansion.

The fiscal architecture that allowed this expansion did not require raising statutory income tax rates. It relied on a different revenue base: corporation tax on highly profitable financial services firms; National Insurance Contributions paid on rising City bonuses; stamp duty on a booming residential and commercial property market; and VAT receipts from credit-financed consumer spending. None of these required the political confrontation of raising the headline rate of income tax. All of them depended on the continued profitability of the financialised economy.

The model assembled between 1979 and 1997, inherited and extended by New Labour, rested on three transmission channels operating simultaneously. Credit expansion through the deregulated mortgage market sustained rising house prices and consumer spending. Rising asset prices supported wage stagnation by providing wealth gains in lieu of real wage growth. And the tax receipts of a globally connected financial sector funded the expansion of the public sector without requiring increases in headline income tax rates.

All three channels were dependent on the continuous functioning of global wholesale credit markets. When BNP Paribas suspended redemptions on three of its money market funds on 9 August 2007, the wholesale markets seized. Northern Rock — funded 75% from wholesale markets, only 25% from retail deposits — was unable to roll its short-term funding and was queueing customers outside its branches by 14 September. Halifax / HBOS, Royal Bank of Scotland and Bradford & Bingley followed in the autumn of 2008. Tax receipts from the City collapsed. PFI deal flow stopped. The structural budget deficit rose to a post-war high.

Strip the politics back, and the period from 1979 to 2008 executed a single, continuous substitution. Out: an economy in which wages were the primary mechanism for delivering living standards, in which housing was a consumption good, in which mortgage credit was rationed by mutually-owned societies, and in which the City existed mostly to service the rest. In: an economy in which credit was the primary mechanism for delivering living standards, in which housing was a leveraged asset class, in which mortgages were funded from global wholesale markets, and in which the City was the central tax base.

The substitution worked, in the sense that real consumption rose, public services were rebuilt, and London became one of two genuinely global financial capitals. It also produced a household sector with the highest debt-to-income ratio in the developed world, a public investment programme dependent on private credit pricing, and a tax base wired to the profitability of a single sector. When that sector contracted, every channel reversed at once. The 2008 crisis was not a financial accident. It was the moment a balance-sheet substitution that had been running for thirty years stopped clearing.
