Oil prices are up around 13 per cent, and LNG – liquefied natural gas – is up around 75 per cent. 20 per cent of the world’s oil and LNG pass through the narrow Strait of Hormuz, a passageway between the Persian Gulf and the Arabian Sea that is effectively being blocked by Iran’s Revolutionary Guards.
