How Russia could act as an economic lifeline for Iran

As Iran faces mounting economic pressure from a US-led blockade of the Strait of Hormuz during the ongoing conflict with Israel, it is increasingly turning to Russia as a potential economic lifeline.

But while ties between Iran and Moscow are deepening, structural constraints may limit how far that support can go, reports Al Jazeera.

Why is Iran looking north?

Iran's economy relies heavily on maritime trade, much of which typically flows through the Strait of Hormuz. A blockade there disrupts a key artery for exports, especially oil, and imports of essential goods.

In response, Tehran is seeking to reorient trade towards northern routes, particularly through Russia and Central Asia, in a bid to reduce reliance on Gulf shipping lanes.

What role can Russia play?

Russia offers Iran an alternative trade partner and transit route. Bilateral trade between the two countries reached $4.8 billion in 2024, growing by 16 percent, with exchanges focused on agricultural goods, machinery, metals and industrial inputs.

Diplomatic engagement has also intensified. Iranian Foreign Minister Abbas Araghchi recently met President Vladimir Putin in St Petersburg, where they discussed sanctions, the war and expanding economic cooperation.

Russia can help supply essential goods such as wheat and machinery, while also serving as a transit hub connecting Iran to broader Eurasian markets.

What is the INSTC and why does it matter?

A key pillar of this strategy is the International North-South Transport Corridor (INSTC), a network of shipping lanes, railways and roads designed to link Russia, Iran, India and beyond.

Goods can move from southern Russian ports across the Caspian Sea to northern Iranian ports such as Bandar Anzali, and then onward by rail or road.

Russia is also backing infrastructure projects, including a rail link between Rasht and Astara in northern Iran, aimed at improving connectivity and increasing trade capacity along this corridor.

Can this replace maritime trade?

Analysts say replacing maritime trade is difficult. Around 90 percent of Iran's international trade is conducted by sea, and shipping remains the most cost-effective method for moving large volumes of goods.

Land-based routes are typically slower and more expensive, which can push up consumer prices and increase spoilage for perishable items.

What about oil exports?

A major limitation is النفط. Iran's economy depends heavily on oil exports, which are currently constrained by the blockade and sanctions. Russia is not in a position to fully compensate for this loss, either by purchasing equivalent volumes or providing alternative export routes at scale.

What are the limits of the partnership?

Despite closer ties, the economic relationship faces structural challenges. Both countries have similar industrial bases and export profiles, which limits complementarities in trade.

Russia is also dealing with its own economic pressures linked to the war in Ukraine, raising questions about its capacity to make large-scale investments in Iran.

What does Russia gain?

For Moscow, supporting Iran may offer strategic benefits. A stronger economic partnership could help entrench the INSTC as a major trade route and reinforce alliances that counter Western influence.

There is also an argument that sustained instability affecting Iranian oil exports could contribute to higher global energy prices, which may benefit Russian revenues.

Russia can provide Iran with an important economic buffer by supplying goods, facilitating trade routes and deepening diplomatic ties. However, logistical constraints, limited trade complementarities and the central role of maritime oil exports mean it is unlikely to fully replace the economic functions of the Strait of Hormuz.
