Russia’s central bank reserves fell to $767.5bn from $775.4bn.
The change equals a decline of $7.9bn over the latest reporting period.
This decline in reserves shows an active defense of the ruble, with the central bank selling foreign currency to prevent its own from falling. We are seeing the first signs of real strain after a relatively calm first quarter of 2026. This intervention suggests that underlying economic pressures are forcing their hand.
The USD/RUB has been held in an unusually tight range of 105-110 for months, but this action is a signal that the managed float could break. Implied volatility on ruble options has already jumped from a low of 19% to 24% just this week. We should be looking at buying out-of-the-money call options on USD/RUB, anticipating a sharp move upward past the 115 level.
This pressure likely comes from falling commodity prices, as Brent crude has slipped to $82 a barrel from over $95 in the fourth quarter of 2025. That represents a significant drop in state revenue, reducing the flow of dollars into the country. This forces a greater reliance on the reserve fund to fill budget gaps and manage the currency.
We remember a similar dynamic in late 2024, where a period of managed currency stability was followed by a sudden devaluation once interventions became too costly. Back then, those who bought volatility through options profited handsomely when the calm shattered. The current setup feels eerily reminiscent, making long volatility strategies attractive.
A weaker ruble will also re-ignite inflation, which had been brought down to a manageable 6.5% for most of 2025. Russia’s central bank may be forced to hike interest rates further, which would put pressure on the domestic economy and stock market. We see this as a cue to consider shorting futures on the MOEX Russia Index as a hedge against this growing instability.
