Japan and Australia Forge Energy and Security Alliance Amid Strait of Hormuz Crisis
Published: May 4, 2026
Japan and Australia have pledged urgent cooperation to stabilize energy supplies and strengthen strategic resilience following severe disruptions to oil flows through the Strait of Hormuz. With 80% of the strait’s oil destined for Asia, the crisis has intensified efforts to diversify energy sources, secure critical minerals, and counter regional instability driven by Middle East conflict.
Japanese Economic Security Minister Sanae Takaichi, speaking in Canberra alongside Australian Prime Minister Anthony Albanese, warned that the effective disruption of oil transit through the Strait of Hormuz is having an 'enormous impact' on the Indo-Pacific region. Approximately one-fifth of global oil passes through the strait, a vital artery now under strain due to heightened military tensions involving Iran, the United States, and Israel. With 80% of that flow bound for Asian markets, the supply squeeze threatens economic stability across major import-dependent economies, particularly Japan, which relies heavily on Middle Eastern energy.
