Generally, no. Loans are financial claims where a creditor lends directly to a debtor, and are evidenced by documents that are not negotiable, i.e., cannot be traded. Cross border data on loans and deposits are available in the BIS International Locational Banking Statistics database.
However, loans that have become negotiable are reclassified from loans to debt securities, in which case they should be included in the CPIS. For such reclassification to occur, there should be evidence of secondary market trading, including the existence of market makers, and frequent quotations of the instrument, such as provided by bid-offer spreads (see the sixth edition of the Balance of Payments and International Investment Position Manual (BPM6) paragraph 5.45).
