In October 2026, Russian investors opened 92.5 thousand new individual investment accounts of the third type (IIS-3), which was the maximum since December 2025, RBC writes, citing data from the Moscow Stock Exchange. Compared to September, the figure increased by 31.6%, and in annual terms - by 41%. The net inflow of funds to IIS-3 for the month reached 43 billion rubles. According to the site, now every fourth ruble in the stock market is invested through individual investment accounts, and the increase in demand, which is not typical for autumn, is partly due to tax factors.
