The US Tariff Campaign Is Building the Bypass It Was Meant to Destroy

In March 2026, the United States did something that exposed the entire logic of its tariff weapon against Russian oil. It issued a temporary waiver on sanctions, allowing Russian crude to flow freely for a month. The reason had nothing to do with Russia: the Middle East was in turmoil after US-Israeli strikes on Iran, and Washington needed to stabilize energy markets. Russian oil revenue surged to $19 billion, nearly double the February low ^[1].

The waiver worked. It also sent an unmistakable signal to every country weighing whether to comply with US tariff threats: American pressure is conditional. When geopolitical necessity demands it, Washington will disable its own weapon. For a government deciding whether to invest billions in a permanent trade corridor that bypasses US-controlled routes, that signal is worth more than any temporary tariff relief. The escalation curve that led to that moment had been steep. In September 2025, the Trump administration imposed 50% tariffs on Indian goods — 25% general plus 25% specifically for purchasing Russian oil ^[2]. By August 2026, the administration was planning to double the rate to 100% ^[3]. Congress granted the president authority to impose tariffs on any country maintaining significant trading relationships with Russia, explicitly targeting China and India ^[4]. Senator Lindsey Graham introduced a bill that would push the rate to 500% ^[5]. Each rung on that ladder was answered by a matching acceleration in bypass construction — not coincidentally, but explicitly. The actors building the corridors said so themselves. **Physical corridors.** In November 2025, Azerbaijan, Iran, and Russia signed a trilateral memorandum to harmonize tariffs and launch regular block trains on the western route of the International North-South Transport Corridor, or INSTC ^[6]. The following month, Iran and Russia reaffirmed their commitment to accelerate the corridor's 162-kilometer Rasht-Astara railway ^[7].

By August 2026, Russia's deputy prime minister was proposing a direct overland railway to the Indian Ocean through Turkmenistan, Iran, Afghanistan, and Pakistan — a route designed to bypass both the Bosphorus and the Strait of Hormuz ^[8].

Other corridors filled in the map. Russia and Azerbaijan established a cargo route through Azerbaijan to Armenia in October 2025, creating a north-south rail link through the Caucasus that bypasses the Western-aligned Georgian checkpoint at Verkhny Lars ^[9]. Afghanistan and Uzbekistan expanded transit cooperation, including the Trans-Afghan Railway Project to link Central and South Asia; Afghan imports from Central Asia were up 43% and exports up 77% in 2025 ^[10]. Turkmenistan and Georgia signed a protocol to build a Caspian-Black Sea transport corridor ^[11]. Not every corridor was a direct response to tariffs. Saudi Arabia's Logistics Corridors Initiative, launched in March 2026 to redirect Gulf shipping to Red Sea ports with 500,000 trucks, was triggered by Iran's restriction of the Strait of Hormuz after US-Israeli strikes ^[12]. The Türkiye-Saudi transit route for petrochemicals and fertilizers, launched in April 2026, was a response to the same chokepoint closure ^[13]. These corridors were born of a different crisis. But they added to the same geography — a thickening web of routes that do not depend on passage through waters the US Navy patrols or through checkpoints on territory aligned with Washington. **Financial infrastructure.** The physical corridors were matched by a parallel build-out of payment systems designed to function outside US reach. China's Cross-Border Interbank Payment System, or CIPS, reached 1.2 trillion yuan in daily transactions by April 2026, with Iran adopting the yuan for oil payments and transit fees — a response to the broader US sanctions regime ^[14]. The Reserve Bank of India proposed linking BRICS central bank digital currencies at the 2026 summit, explicitly to reduce reliance on the US dollar and SWIFT and to mitigate sanctions risk ^[15]. India's central bank was simultaneously operationalizing bilateral CBDC pilots with Singapore, the UAE, and Vietnam ^[16]. Russian businesses reverted to barter — swapping wheat and flax seeds for Chinese cars and appliances — to circumvent the 25,000-plus Western sanctions and SWIFT disconnection, with the Ministry of Economy issuing an official barter guide ^[17]. Saudi Arabia and Syria implemented direct bank transfers outside SWIFT, while Riyadh invested $6.4 billion in Syrian infrastructure including a fiber-optic backbone ^[18][19]. These financial instruments responded to the broader sanctions regime, not solely to tariff escalation. But the tariff weapon deepened the incentive to use them. A country facing 50% tariffs on its entire export base — and the prospect of 100% or 500% — is a country that needs payment rails its largest trading partners can use without American permission. **Trade agreements.** In November 2025, India launched formal free trade negotiations with the Russia-led Eurasian Economic Union, with an 18-month roadmap ^[20].

Russia's foreign minister, Sergei Lavrov, made the dynamic plain ^[21].

Both China and India are ancient civilisations. And talking to them like ‘either you stop doing what I don’t like or I’ll impose tariffs on you’ won’t work. — Sergey Lavrov

The tactical damage was real. Russian oil revenues fell to pandemic-era lows of $5.1 billion in January 2026 under combined US-EU sanctions and tariff pressure ^[22]. India cut Russian crude imports and, by February 2026, formally committed to stop importing Russian oil "directly or indirectly" as part of a trade deal ^[23]. Trump claimed in November 2025 that India had "largely" stopped buying Russian oil ^[24]. But the compliance did not hold. India's government called its purchases a "sovereign decision" and denied agreeing to a permanent halt ^[24]. By early 2026, Indian imports of Russian crude had climbed back to 43% of the total ^[25]. Russia adapted by pivoting to LNG and coal exports to India, with the energy minister offering expanded LNG supplies and targeting 40 million tonnes of coal by 2035 ^[26]. The trade was displaced, not eliminated — and the displaced trade flowed through the same corridors being built. Then there is the second contradiction, the one that makes the first irreversible. While the US tariff weapon was pushing India, China, and others toward the INSTC and its associated financial architecture, Washington was simultaneously building a rival corridor of its own. The Middle Corridor — a Trans-Caspian route through Kazakhstan, Azerbaijan, Georgia, and Türkiye — is the US-aligned bypass, the "controlled" one. The Commerce Department certified trade missions to the route in September 2025 ^[27]. US businesses explored building an oil refinery at Aktau, on Kazakhstan's Caspian coast. American partners participated in the construction of the Zangezur Corridor through Armenia ^[28]. The two policies share a premise: that the geography of global trade is being redrawn, and the US needs a route it can influence. But the tariff weapon is pushing the exact countries the Middle Corridor needs — India and China, the largest Russian oil buyers and the economies whose cargo would make any corridor viable — toward the rival route. You cannot punish a country for using one corridor while asking it to use yours. By April 2026, the INSTC network was carrying ordinary commerce, not just sanctioned cargo. Over 25,000 tons of grain and 1,600 tons of fertilizer had been shipped from Russia to Armenia via Azerbaijan, plus 8,500 tons of diesel and 4,000 tons of gasoline directly from Azerbaijan ^[29]. Armenian imports of Russian LPG and agricultural products were flowing by rail through Azerbaijan, explicitly to bypass congestion at the Russia-Georgia border ^[30]. Afghan imports from Central Asia were up 43% ^[10]. A rail line carrying Armenian fuel and Afghan grain is not a sanctions-evasion route that can be isolated and unwound. It is a trade corridor. The weapon was built to stop a specific trade. It has financed a general one.
