clause kept out new companies until it was repealed in 1824, Lloyd’s pri-
vate underwriters dominated marine insurance in the eighteenth century
(Supple 1970: 53, 186).
Liquid, secure government securities also played an essential role in
the development of insurance. Insurance companies needed liquid assets
to meet unexpected claim demands, so insurance companies preferred
securities to mortgages, and government debt was particularly favoured.
Forexample, from 1734 to 1784, government securities rose from being
22 per cent to 54 per cent of the Royal Exchange Assurance’s assets, and
in 1840 their share peaked at 70 per cent (Supple 1970: 74, 314). Mutual
fire insurance societies also made heavy use of South Sea annuities and
Consols (John 1953: 144–5). The reliance on the liquidity of government
securities by insurance companies only declined in the middle of the
nineteenth century as life insurance companies grew so large that cash
requirements could be confidently predicted (Supple 1970: 314).
English savings banks also relied on government debt. Begun in
Ruthwell, Scotland, in 1810 as a charity, savings banks allowed the work-
ing class to earn interest on small-value deposits (Horne 1947: 43). The
concept was wildly popular with members of the upper class who desired
to promote thrift among the working poor, so, by the end of 1815, all of
Scotland except the far north had access to a savings bank (Horne 1947:
50). The concept soon moved south; however, private banks in England
would not pay savings banks for deposits like Scottish banks did. The
English solution was for the government to offer savings banks a guaran-
teed, above-market rate of return for money invested through the Bank
of England into a special account of the national debt (Horne 1947: 77–8).
The bill became law in 1817, and about 150 new savings banks formed
within twelve months after passage. The total amount those savings banks
held in their special fund at the Bank of England increased by an aver-
age of one million pounds per year over the next thirty years (Horne
1947: 116) and provided a way for working-class Britains to gain access
to reasonable rates of return on their savings yet still have the ability to
liquidate those savings if needed.
The Napoleonic Wars also brought changes to the stock market. War
shocked the market for government securities with increased volume
and volatility, while refugees from Paris and Amsterdam brought experi-
enced traders who were new to the London market (Michie 1999: 33–4).
The resulting problem of traders defaulting began harming the liquidity
of government securities, so the exchange on Sweetings Street organised
to limit access to the market. In March 1801, the stock exchange changed
itself into a subscription room with rules of behaviour, controlled admis-
sion, administration paid by subscriptions, monitoring, and enforcement
by thethreat of expulsion (Michie 1999: 35). The exchange soon refused
admittance to members whose principal business was not brokering or
jobbing, to avoid linkages between external business failure and members
