Russia's invasion of Ukraine is creating instability in the financial markets, with European stock markets falling, and the effects reflected in energy and food prices. A war scenario brings with it a humanitarian crisis and it is the most vulnerable who suffer the worst consequences. Based on these events it is intended in this paper to test the persistence of returns on the IMOEX capital market, Russian Sovereign OT (10 YR), and the WTI oil index over the period April 24th, 2017, to April 22nd, 2022. To perform this analysis different approaches were undertaken to analyse, if: (i) do the analysed markets exhibit persistence in their returns? The results suggest that the returns do not follow the i.i.d. hypothesis from dimension 2, reinforcing the idea that time series returns are nonlinear in nature or have a significant nonlinear component, except for the Russian capital market, which was expected considering the results of the Ljung-Box (with squares of the returns) and ARCH-LM tests. |
