A Brief History of the 12-Day War

The origins of the 12-Day War trace back to long-standing regional rivalries, exacerbated by recent events. Israel and Iran have been at odds for decades, with tensions rooted in ideological differences, Iran’s support for proxy militias like Hezbollah, and Israel’s concerns over Iran’s nuclear ambitions. While direct military confrontations have been rare, the two nations have engaged in shadow wars, including cyberattacks, assassinations, and strikes on each other’s assets.

The 12-Day War began on June 11, 2025, following a series of rapid escalations. According to reports circulating on X, the conflict was sparked by an Israeli airstrike on Iranian military targets, allegedly in response to intelligence suggesting an imminent Iranian attack. Iran retaliated with missile strikes on Israeli territory, marking a rare direct assault. Over the next twelve days, both sides exchanged airstrikes, drone attacks, and cyber operations, causing significant damage to infrastructure, including energy facilities critical to the region.

The war’s impact on energy markets was immediate. Iran, a major oil producer, faced disruptions to its export capabilities due to damaged port facilities, while Israel’s natural gas fields in the Mediterranean were temporarily halted amid security concerns. Brent crude prices surged past $90 per barrel, reflecting fears of a prolonged conflict in a region that accounts for nearly a third of global oil supply. The conflict also raised concerns about the security of key shipping routes, such as the Strait of Hormuz, through which 20% of the world’s oil passes.

President Trump’s Ceasefire Announcement

On June 23, 2025, President Donald J. Trump announced via his Truth Social platform that Israel and Iran had agreed to a “Complete and Total CEASEFIRE” set to begin approximately six hours after his statement, lasting for 12 hours. “CONGRATULATIONS TO EVERYONE! It has been fully agreed by and between Israel and Iran that there will be a Complete and Total CEASEFIRE…” Trump wrote, as echoed by the White House’s official X account and other users on the platform.

According to posts on X, the ceasefire was brokered following intense diplomatic efforts, with the United States playing a central role. Trump’s announcement suggested that the initial 12-hour truce could pave the way for a permanent resolution, potentially ending what he referred to as the “12 Day War”. The announcement was met with widespread attention, with some X users praising Trump’s diplomatic intervention, while others questioned the motives and outcomes of the ceasefire. Notably, one X post from @YourAnonCentral
claimed that Israel had proposed a ceasefire less than 12 hours prior, suggesting Trump was taking credit for an Israeli initiative. The post further argued that the conflict strengthened Iran’s regime and secured its nuclear capabilities, raising doubts about the long-term efficacy of the truce. These claims remain unverified, and Energy News Beat urges readers to approach such assertions critically, as X posts reflect sentiment rather than conclusive evidence.

Potential End to Hostilities and Energy Implications

The ceasefire, if it holds, could mark a turning point for the region and global energy markets. A de-escalation between Israel and Iran would likely stabilize oil and gas prices, which have been volatile since the conflict began. The restoration of Iran’s oil exports and Israel’s natural gas production could ease supply concerns, potentially lowering Brent crude prices in the near term. However, the Strait of Hormuz remains a critical chokepoint, and any lingering tensions could keep markets on edge.

Beyond energy, the ceasefire has broader geopolitical ramifications. A sustained truce could reduce the risk of proxy conflicts involving groups like Hezbollah or Hamas, fostering a more stable Middle East. However, the underlying issues—such as Iran’s nuclear program and Israel’s security concerns—remain unresolved. X posts suggest mixed sentiment, with some users optimistic about peace and others skeptical of Iran’s intentions.

For the energy sector, the ceasefire offers a reprieve but no guarantees. Companies operating in the region, from ExxonMobil to BP, will be closely monitoring the situation, as will investors in energy ETFs and futures markets.

Conclusion

The 12-Day War between Israel and Iran has been a stark reminder of the fragility of peace in the Middle East and its ripple effects on global energy markets. President Trump’s announcement of a ceasefire on June 23, 2025, offers hope for an end to hostilities, but the path to lasting peace remains uncertain. As the world watches, the energy sector braces for both opportunities and risks in the wake of this tentative truce.
