<abstract xml:lang="en"><p>The article tests the hypothesis that the intensity of the sanctions news flow, measured by the Sanctions News Index (SNI), contains leading information about changes in the volatility of the Russian financial market. The volatility of the currency, stock and credit market segments is analyzed based on daily data for 2014-2025. The methodology combines the Granger causality test and EGARCH modeling. The results show that the SNI contains statistically significant leading information on the volatility of all three segments, and the revealed relationship is reproduced for both realized and expected risk by the market. This indicates the universality of the proposed approach to evaluating the information channel in relation to the main segments of the Russian financial market. An additional assessment of Value at Risk and Expected Shortfall allows to translate the identified effect into a cost dimension and assess the economic scale of increased information pressure. The information channel is considered as an active trigger of volatility and risk, triggering the processes of preventive relocation of capital even before the legal consolidation of measures. This allows to fill in the existing gap related to the assessment of risk as a result of expectation damage, which classical methodologies often classify as information noise.</p>

<trans-abstract xml:lang="ru"><p>В статье проверяется гипотеза о том, что интенсивность санкционного новостного потока, измеряемая Sanctions News Index (SNI), содержит опережающую информацию об изменении волатильности российского финансового рынка. На основе дневных данных за 2014–2025 гг. проводится анализ волатильности валютного, фондового и кредитного сегментов рынка. Методология сочетает тест причинности по Грейнджеру и EGARCH-моделирование. Полученные результаты показывают, что SNI содержит статистически значимую опережающую информацию о волатильности всех трех сегментов, причем выявленная связь воспроизводится как для реализуемого, так и для ожидаемого рынком риска. Это свидетельствует об универсальности предложенного подхода к оценке информационного канала применительно к основным сегментам российского финансового рынка. Дополнительная оценка Value at Risk и Expected Shortfall позволяет перевести выявленный эффект в стоимостное измерение и оценить экономический масштаб усиления информационного давления. Информационный канал рассматривается как активный триггер волатильности и риска, запускающий процессы превентивной релокации капитала еще до юридического закрепления мер. Это позволяет заполнить существующую лакуну, связанную с оценкой риска в результате «ущерба от ожиданий», который классические методологии часто классифицируют как информационный шум</p>
