В статье тщательно изучены предпосылки для проявления коинтеграционных связей на фоне колебаний обменных курсов AZN/TL и USD/TL в течение первой половины 2023 года в условиях, характеризующихся резким обесцениванием турецкой лиры.Материалы и методы. В работе используются современные эконометрические методологии, в том числе тест коинтеграции Йохансена, тест причинности Грейнджера, векторная коррекция ошибок и другие соответствующие подходы.Результаты. В исследовании были динамически проанализированы причины девальвации турецкой лиры, ее влияние на экономику Азербайджанской Республики и обменный курс AZN/TL. Коинтеграционная модель взаимного влияния была создана посредством точного применения эконометрических тестов. Коэффициент восстановления дисбаланса составил -0,933745, обеспечивающим возврат траектории в исходное состояние в последующий момент после отклонения от состояния равновесия. В случае разницы первого порядка USD/TL этот коэффициент составляет -0,242442, хотя и статистически является незначимым. Интерпретация полученной модели указывает на то, что обесценивание турецкой лиры по отношению к доллару не оказывает существенного влияния на колебания курса AZN/TL.Заключение. Результаты исследования показывают, что хотя курс USD/TL и оказывает влияние на курс AZN/TL, экономика Азербайджанской Республики не пострадает серьезно от девальвации турецкой лиры.</p></abstract><trans-abstract xml:lang="en"><p>Purpose of the study. The article scrutinizes the prerequisites for the manifestation of cointegration associations amid the fluctuations in the AZN/TL and USD/TL exchange rates during the initial half of 2023, under the circumstances characterized by the precipitous depreciation of the Turkish lira.Materials and methods. The study employs contemporary econometric methodologies, encompassing the Johansen cointegration test, Granger causality test, vector error correction, and other pertinent approaches.Results. The research dynamically scrutinizes the underlying causes of the Turkish lira’s devaluation, its impact on the economy of the Republic of Azerbaijan, and its influence on the AZN/TL exchange rate. A cointegration model of reciprocal influence was established through the accurate application of econometric tests. The imbalance recovery coefficient was found to be -0.933745, ensuring that the trajectory reverts to its original state in the subsequent moment after deviating from the equilibrium state. In the case of USD/TL the first order differences, this coefficient is -0.242442, albeit statistically insignificant. The interpretation of the established model indicates that the depreciation of the Turkish lira against the dollar does not exert a significant impact on the fluctuations in the AZN/TL exchange rate.Conclusion. The findings of the research indicate that while the USD/TL does exert an influence on the AZN/TL, the devaluation of the Turkish lira does not significantly impact the economy of the Republic of Azerbaijan.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>обменные курсы</kwd><kwd>нестационарные ряды</kwd><kwd>тест коинтеграции Энгла-Грейнджера</kwd><kwd>коррекция ошибок</kwd><kwd>тест Йохансена</kwd></kwd-group><kwd-group xml:lang="en"><kwd>exchange rates</kwd><kwd>non-stationary series</kwd><kwd>Engle-Granger cointegration test</kwd><kwd>error correction</kwd><kwd>Johansen test</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Azerbaijan Manat to Turkish Lira Exchange Rate Chart [Электрон. ресурс] // xe.com.
