The US and Israel are considering a land blockade of Iran to increase economic pressure, senior Israeli sources told The Telegraph

• The plan could involve urging neighbouring countries and regional partners to restrict border crossings and trade.
• Some have warned that enforcement would be diplomatically and logistically difficult across Iran’s seven land borders.

Proposals of this kind sit in the escalation-by-attrition category that has recurred in US policy toward Iran: tightening economic pressure short of direct military engagement, with the market-facing channel running through crude supply expectations rather than through trade volumes themselves. The distinction that matters is between a land blockade, which would compress Iran's non-sanctioned overland commerce, and any disruption to seaborne crude or the Strait of Hormuz, which is the scenario that has historically driven a durable risk premium into oil; land-border measures alone have tended to add only a modest and fading bid absent a maritime component. Enforcement across multiple land borders with neighbours of varying alignment has, in past sanctions episodes, proven porous, and the economic leakage through partners unwilling to comply is the standard reason such measures underdeliver relative to headline framing. Attribution to unnamed senior sources via a single media outlet is also a familiar pattern in this theatre, where floated options sometimes function as signalling rather than policy, so confirmation from official US channels is the near-term tell. The follow-ons worth noting are any response from Tehran, whether neighbouring states are actually approached, and whether the discussion migrates from land routes toward shipping or insurance, which is where the transmission to crude, freight rates and gold has historically run.
