The article deals with the problem of analysis of banking activity and modern methods of investment development of the bank based on pairs trading models. The essence of the pair trading method as one of the most popular and qualitative methods of investment paper quality analysis is disclosed. The basis of the pairing trading method is defined as the beta-neutral portfolio strategy, which consists of creating a portfolio with a beta coefficient equal to zero, and the main advantage of which is the complete independence of the final paper yield from the market yield, it is only dependent on the future ratio of the value of one security to another. For the successful introduction of this method in banking activity, a clear algorithm for the construction of a paired trading model based on economic-mathematical methods and models is proposed. The proposed algorithm contains three stages in which the following steps are to be taken: analysis and selection of securities; development of a pairing trading model; development and regulation of the selected strategy. The implementation of the proposed algorithm begins with the selection of statistical data on the prices of securities, provides for the verification of data on stationarity, as well as the identification of a system for combining series, and the analysis of coefficients of the matching between prices of securities. As a result of the steps taken, pairs of securities are selected that are more closely related and a full economic analysis of the pairs is made, and the parameters of co-integration equations to pairs of paper are selected, evaluated and analyzed then the errors of the co-integration model are checked for stationary. In the work models of pairs trading are constructed for the realization of an aggressive strategy of trade spreads. In order to build an effective strategy for pairing trading, data on prices of securities, which are the most attractive to Ukrainian banks, namely, US Treasury bonds, have been examined. The hypothesis being tested in the paper is that it is necessary to identify a pair of securities with a sufficiently strong dependency where one should have a rapid growth or decline relative to the other, after which the sale of the revalued security and the purchase of the undervalued security is mandatory. The study found that for each pair of Treasury bonds, the ratio was satisfactory. This indicates that the resultant securities pairs are suitable as an investment that, with a well-designed strategy, will allow the bank to obtain optimum returns. The final step of the algorithm is the analysis of the results obtained, which includes a comprehensive analysis of the conducted research and effective decision-making. The application of the proposed algorithm will allow banks to make informed decisions on the choice and regulation of the strategy in exchange market changes in order to obtain a low level of risk and a high level of profit.
