payments. The longer the war lasted, the greater the need of the Allied
countries for American products, for which only Britain could pay in
dollars. The pressure became relentless. To pay for British and Allied
purchases, the Treasury bought up British-owned dollar securities (with
sterling) and sold or pledged them in New York. It exported some of
the precious reserve of gold. And it borrowed from American bankers,
using the great firm of J. P. Morgan to raise dollar loans on its behalf.
At all costs, it had to prevent a collapse in the value of sterling against
the dollar. For, if American sellers and lenders lost confidence, Amer-
ican goods would become impossibly expensive and bring the Allied
war effort to a standstill.
For Keynes, therefore, the economic pivot of the war was
Britain’s credit in New York. If it failed, the Allies were finished. ‘We
have one ally’, Keynes told the Admiralty board in March 1916, ‘the rest
are mercenaries.’

There was no certainty that American lenders would
continue to buy British bonds when their own economy was booming.
If American opinion was alienated by some transatlantic quarrel, the
effect might be devastating. For the rest of 1916, however, disaster was
postponed. The British dribbled their gold (and that of their Allies)
into the New York market. They spent heavily to hold up the value of
sterling. The American investor, despite Keynes’ pessimism, remained
a willing buyer of Allied loans. But, by the end of 1916, the huge
reserves of British financial power had reached the limits that Keynes
predicted. In November 1916, the American authorities, disturbed by
the rapid growth of so much debt, advised their banks to curtail for-
eign loans. At the same time, as the gold reserve in London reached
a critical level, and dollar securities began to run out, British depen-
dence on American lending became greater than ever. At the moment
when the Asquith cabinet fell in early December, the Treasury privately
calculated that it was scarcely a week away from exhausting its dol-
lars. The immediate danger of a sterling collapse receded. But, in the
spring of 1917, as Germany’s unrestricted submarine warfare brought
the United States closer and closer to intervention, there was barely a
month’s reserve in hand before a drastic reduction of British purchases
would have been necessary.

Even after American entry in April 1917,
the strain and uncertainty were intense. A hold-up on American cred-
its in June brought the British to the point of default.

On 29 July
1917, Bonar Law, now Chancellor of the Exchequer, told his American
counterpart, William Gibbs McAdoo, that, without urgent help, the
