This article reports the results of two surveys, at end-March and end-May, of the euro-currency maturity positions of London banks. Since March 1973 these surveys, regularly reported in the Bulletin, have been made half-yearly, in March and September. The pressures on the market associated with the recycling of oil funds make it worthwhile now to increase the frequency of surveillance. Beginning with the May survey, reports will be called for quarterly, and the figures will be published in each issue of the Bulletin. The additional information by country on UK banks' borrowing and lending in overseas currencies, given for the first time in the June Bulletin, will also now be published regularly.
