The Russian stock market has accelerated its downward trajectory, recording its sharpest weekly decline in almost four years.

The sell-off marks the culmination of a 3.5-month bearish phase that has systematically eroded investor confidence in the domestic equity landscape.

Major blue-chip companies, including the nation's largest corporate entities, are now trading at valuations not seen since the early stages of the current economic cycle.

The repricing reflects a deepening crisis of confidence among both domestic and remaining international participants.

With capital controls and geopolitical isolation limiting exit routes, the selling pressure appears driven by fundamental reassessments of corporate viability and currency risk.

The breadth of the decline suggests that the market is no longer pricing in short-term volatility but rather a structural de-rating of Russian assets.
