were expected to produce only £250 million for defence. By June 1939
the Treasury was contemplating a rise from the current standard rate of
income tax of 5s 6d (27.5p) to a new, permanent, rate of 7s 6d (37.5p )
in the pound, higher than the maximum rate of 6s (30p) reached in the
First World War.

Treasury arguments against unlimited defence expenditure were not
purely financial, although officials did believe that repeated borrowing
would cause inflation, as it had done in the First World War. In 1937 they
used the concept of economic stability as a fourth arm of defence. On this
view, the real resources of the country were its manpower, productive
capacity, trade, and ability to raise loans. Britain had to import raw
materials and food, and nothing should be done to undermine industry’s
ability to export. The amount that the government could borrow
depended upon two factors: the savings of the community and confidence
in financial stability. If the government attempted to borrow more than
the money market was willing to lend, the Bank of England would have to
create credit and the result would be inflation. Higher domestic prices
would have an adverse effect on exports, savings would be reduced, and
financial confidence would be weakened. In order to be able to wage the
long war that the Chiefs of Staff’s plans envisaged, Britain would have to
maintain its economic stability so that she would have greater staying
power than Germany.

Chamberlain shared this line of thought,
although his concerns were not purely economic or strategic. On 25 April
1937, shortly before becoming prime minister, he noted that expenditure
on rearmament was causing prices to rise, and feared that in consequence
there might be ‘a series of crippling strikes ruining our programme, a
sharp steepening of costs due to wage increases, leading to the loss of our
export trade, a feverish and artificial boom followed by a disastrous
slump, and finally the defeat of the Government’.

Economic stability was also necessary to maintain confidence in
sterling. Sterling was used to finance international trade through
London, and overseas sterling balances were held there to facilitate
transactions. Sterling balances also formed all or part of the official
reserves of countries forming the sterling area: the dominions, except
Canada after 1931; India; British colonies, except Hong Kong; and
