The Bankers' Trust divided the figures for each year by the aver age wholesale price index number for the year, thus putting the statistics for each country on the 1913 price basis. The adjusted cost figures were then converted into dollars at par of exchange, and on that basis the real cost of the war in 1913 dollars is esti mated at 80,681,000,00o dollars, or in sterling a little more than £16,000,000,000, which, of course, is a very different figure to the actual gross currency costs recorded in the foregoing table.
The total expenditure in the case of most of the countries enu merated in the table can be regarded as the outside amount, but the two notable instances where the net cost might be reduced if allowance were made for loans to allies, are the British empire and the United States. British loans are over £100,000,000 to dominions and colonies, while at March 31, 1928, loans due to Great Britain included £706,000,000 from France, £266,000,000 from Italy, iioo,000,000 from various smaller European States, and £887,000,000 from Russia, the last item, however, being regarded somewhat in the light of a bad debt.
Previous to 1914 Great Britain, by reason of her seniority among the big nations resulting in an accumulation of savings and a prestige in the matter of manufacturing, had the leading place among the nations in financial lending power and control over the exchanges, conditions in their turn contributing to her power as the leading monetary centre of the world. As a consequence of the war, or, rather, as a consequence of the three years of neutrality on the part of the United States during the war, the equipoise of the balance of trade was completely destroyed, and at the end of the conflagration the belligerent countries of Europe became debtors to the United States, first, on account of the colossal trade balance in favour of America, and, second, because of the actual debts incurred by the belligerent nations to the United States Government. All this, so far as Europe is con cerned, has to be reckoned amongst the indirect costs of the war, and to express that cost in figures is impossible. Whether, on the other hand, an equivalent of the unknown amount to be debited to the belligerent countries of Europe is to be credited to the United States is not only debatable but a controversial subject, because economists in the United States of America often plead that, as a matter of fact, economic progress in their country was retarded rather than helped by the four years' war.
It may be mentioned that in a lecture delivered before the London Institute of Bankers in June 1920 by Edgar Crammond on "The Real Cost of the War," an attempt was made by that statistician to appraise the real net cost of the war after making all allowances for revenues or territories gained or lost. The re
sult was, naturally, to reduce materially the gross cost. Thus he estimated the net real cost of the war to Great Britain at only £3,500,000,000; France at L5,400,000,000; Italy at £2,100,000, 000 and so on while for the five years ended 1919 the United States was reckoned to have gained materially in wealth.
