Financial Market Regulation and Monetary Policy on Financial Stress Management in the National Economy

Introduction. Neutralising the dynamic threats of war and economic crises and reducing the stress index for the country's financial system requires prompt action from the regulator. This allows financial market participants to reduce the stress index of the country's financial system. However, dynamic changes and the lag in time for the introduction of regulatory actions create challenging conditions for the activities of financial market participants, which determines the relevance of studying the functioning of Ukrainian financial markets. Aim and tasks. This study aims to identify the key indicators of financial market conditions and the level of effectiveness of regulatory influence on these indicators. Results. It is indicated that changes in the conditions for the functioning of the Ukrainian financial market in 2022-2023, with a reduction in the profitability of financial market participants by 152%, an increase in the share of non-performing loans by 19%, and a reduction in funds in banks’ correspondent accounts only for the first quarter of 2022 by 30%, led to an urgent need for regulatory action. These actions increased the liquidity coverage ratio by 3.27 times and reduced the Financial Stress Index by 59.79%. Simultaneously, the long-term liquidity ratio increased by only 7%, indicating uneven liquidity dynamics. A cumulative negative effect is noted, even when using the regulator's monetary policy instruments for 2022-2023. The money supply increased by 21.03%, the monetary base increased by 25.77%, and the volume of cash outside banks increased by 8.24%. This necessitates strict control over capital movements, taking into account the impact of this factor on the reduction in the activity of market participants. Conclusions. The directions of the monetary policy of the regulator of Ukraine are indicated, in particular, increasing the level of lending to financial market participants, solving the problem of liquidity surplus in banks, and regulating relative prices, which contributes to reducing the level of financial stress. This indicates that the activities of financial intermediaries in martial law conditions acquire new significance as a damper of fluctuations in financial market risks, particularly the risks of financial transactions. This indicates that the financial market has not acquired a proper level of stability, and the stress index fluctuated up to 65% of the average value for the study period.
