MOEX Index Rises on Geopolitical Hopes While Oil Slide Pressures Ruble

MOEX Rises, RTS Falls: Oil and Geopolitics Split Moscow's Benchmarks

Moscow's two main equity benchmarks ended Tuesday, August 4, in opposite directions. The ruble-denominated MOEX index added 0.29% to close at 2,269.23 points, while the dollar-denominated RTS index lost 1.02% to 881.14 points — a gap that reflects both a weaker ruble and a sharp drop in oil prices.

The strongest performers of the session were export-oriented names: Alrosa gained 4.61%, Rusal 4.27%, Norilsk Nickel 2.84%, Moscow Credit Bank (MKB) 2.42% and En+ Group 1.45%. Losers included Rusagro (-4.32%), Dom.RF (-1.89%), VTB (-1.88%), Tatneft preference shares (-1.75%) and Sovcombank (-1.32%).

On the currency side, the Chinese yuan firmed slightly on the Moscow Exchange to 11.95 rubles (+0.08%). The Bank of Russia set official rates at 81.10 rubles per US dollar (+1.10) and 93.58 rubles per euro (+1.60). Oil fell hard: October Brent futures settled 4.1% lower at $80.40 per barrel, and September WTI dropped 5.7% to $75.80.

According to BCS stock market analyst Andrey Smirnov, the falling oil price was the main negative factor, offset by lingering hopes for a resumption of negotiations over the Ukraine conflict and by reinvestment of recently paid dividends. Global equities meanwhile rose on reports that US President Donald Trump intends to pursue a diplomatic settlement with Iran, while Beijing's announced measures to support Hong Kong's market added to risk appetite in China.

Why Exporters Rose, the Ruble Slid and Oil Remains the Swing Factor

Why the Two Benchmarks Diverged

Verified session data show MOEX rising while RTS fell, which points to currency, not company fundamentals, doing much of the work. A weaker ruble lifts the local-currency value of export revenues, which helps explain why commodity producers such as Alrosa, Rusal and Norilsk Nickel led the MOEX gainers, while the same currency movement mechanically drags the dollar-denominated RTS lower. The ruble's official rate was set 1.10 rubles weaker against the dollar on the day.

The Ruble's Triple Drag, and BCS's Call for Stabilisation

Smirnov attributes the currency's weakness to three forces: seasonal demand for foreign currency, rising importer activity, and a likely reduction in foreign-currency supply as June oil prices — which fell nearly 30% that month — feed into export receipts. The Bank of Russia's ongoing key-rate cutting cycle adds further pressure. Interpretation: the ruble's near-term fate is tied more to oil and the central bank than to equity flows. BCS expects the July recovery in oil prices to support the currency in the second half of August, and sees a possible Ukraine negotiation track compressing the geopolitical risk premium.

What Could Move the 2200–2300 Range

Smirnov sees the MOEX index staying within 2200–2300 points until fresh geopolitical input arrives, with a short-term yuan forecast of 11.8–12.1 rubles and a dollar forecast of 80–82 rubles. This week's scheduled catalysts are concrete: services PMI prints for China, the eurozone and the US, the Bank of Russia's summary of key-rate discussions, Rosstat's weekly consumer price data, and the finance ministry's announcement of budget-rule currency operations for the coming month. Each of these is a potential trigger for the ruble and for rate-sensitive Russian stocks.

Watchlist: PMI Data, CBR Minutes and Budget-Rule FX Flows

• Expect the MOEX index to remain rangebound at 2200–2300 points until new geopolitical developments emerge; BCS pegs the dollar at 80–82 rubles and the yuan at 11.8–12.1 rubles in the short term.
• Watch Wednesday's releases for the next directional signal: services PMI for China, the eurozone and the US, the Bank of Russia's key-rate discussion summary, Rosstat's weekly inflation data and the finance ministry's budget-rule FX volumes.
• Foreign-currency buyers should note BCS's view that stabilizing oil prices should support the ruble from the second half of August, when June's steep oil decline stops suppressing export FX supply.
• For holders of Russian equities, the session's pattern — exporters gaining on a weak ruble — underscores how currency moves, rather than company news, are currently driving sector rotation.
