**6. Conclusion**

We have conducted a study of the synchronization level of LEE countries' economic cycles. At the same time, two methods were used: Hodriсk-Preskott filtering and spectral analysis. Thanks to the Hodrick-Preskott filtering we have found the multidirectional nature of the output gap dynamics of large emerging economies, which allowed us to conclude about the lack of synchronization of economic cycles and about the impossibility of supporting the decoupling hypothesis at present. Similar results were obtained by spectral analysis. Thus, the various alliances of major emerging economies currently have more geopolitical grounds than economic ones and are a manifestation of geoeconomic fragmentation rather than integration.
