Severity: WARNING

Summary
At around 07:19–07:36 UTC, former Russian president Dmitry Medvedev said the Hague Conventions are ‘no longer needed’ against Kyiv and described the Strait of Hormuz as a ‘Persian nuclear weapon’ that will be used as such. The statements signal a deliberate loosening of Russia’s self-imposed restraints in Ukraine and tie Moscow politically to Iran’s ability to choke a key oil artery, raising both escalation and energy‑supply risk.
Details
Former Russian president and Security Council deputy chair Dmitry Medvedev used a series of public statements around 07:19–07:36 UTC to strip away remaining rhetorical limits on Russia’s conduct in Ukraine and to frame the Strait of Hormuz as a strategic weapon tied to Iran.
In two overlapping messages circulating on Russian and international channels, Medvedev said that “there can no longer be any rules when dealing with Kyiv,” that “the Hague Conventions on the laws and customs of war are no longer needed,” and that the only remaining restriction for Russia is to avoid the deliberate killing of civilians. He justified the shift by citing what he called “massive terrorist attacks” on Russian cities. In a separate comment, he said the Strait of Hormuz has become a “Persian nuclear weapon” and “will be used as such,” suggesting that closure or disruption of the waterway is now viewed by Moscow as a legitimate coercive tool for Iran and its partners.
These statements are not official decrees, and Medvedev does not command Russian forces. But as deputy chair of Russia’s Security Council and a close ally of President Vladimir Putin, his rhetoric has repeatedly previewed policy moves and helped normalize escalatory steps domestically. Openly discarding the Hague Conventions lowers the political barrier for Russian commanders to use more destructive means, including expanded targeting of dual‑use infrastructure, energy grids, bridges, and transport nodes in Ukraine, under the pretext that traditional laws of war are obsolete.
For civilians in Ukraine, any erosion of adherence to humanitarian law would likely translate into more aggressive strikes on urban-adjacent infrastructure and potentially harsher treatment of prisoners and occupied populations. On the Russian side, portraying Ukrainian attacks as “terrorism” gives further justification for broad crackdown measures and sustained mobilization, deepening the war’s social and economic drag.
The Hormuz comment matters beyond rhetoric. By calling the strait a “Persian nuclear weapon,” Medvedev is signaling political alignment with Iran’s leverage over a corridor that carries roughly a fifth of globally traded oil. In the context of ongoing U.S.–Iran negotiations and reports of efforts to unlock Iranian funds, this language could be read in Gulf capitals, shipping firms, and energy markets as a reminder that, in a crisis, Iran and its partners might threaten or disrupt traffic through Hormuz. Even without immediate action, such talk adds to the perceived risk premium on Gulf crude and tanker insurance.
Market impact in the next 24–48 hours will hinge on follow‑up signals from the Kremlin and Tehran. If Russian military activity in Ukraine shows a marked shift toward more indiscriminate or infrastructure‑focused strikes, energy and grain markets may re‑price higher on expectations of prolonged conflict and further damage to Ukrainian export capacity. Any concurrent Iranian statements echoing the Hormuz threat, or unusual naval deployments near the strait, would quickly push Brent and Dubai benchmarks higher and widen tanker insurance spreads.
Key points to watch: (1) Kremlin or Defense Ministry commentary either distancing from or implicitly endorsing Medvedev’s remarks; (2) changes in Russian rules of engagement as reflected in target sets in Ukraine over the coming days; (3) Iranian media or IRGC-linked channels amplifying the “nuclear weapon” framing of Hormuz; (4) U.S., EU, and Gulf diplomatic responses, including warnings over freedom of navigation; and (5) price and volatility shifts in Brent, WTI, front‑month crude options, and Middle East shipping insurance as traders test how much of this rhetoric to price in.
MARKET IMPACT ASSESSMENT: Comments raise perceived tail risk of legal-norm breakdown in Ukraine and disruption around the Strait of Hormuz. Expect some safe-haven bid into gold and USTs, a modest geopolitical risk premium in Brent, and closer scrutiny of Russian and Iranian assets. Actual price impact will depend on follow-through from Moscow or Tehran.
