Japan’s currency slipped to 160 yen to the dollar on Monday, its lowest rate since 1990, triggering a government intervention and threatening Prime Minister Fumio Kishida’s position.

Voters are frustrated by Japan’s high cost of living, but a change in leadership is unlikely to alleviate the pain. The heavily populated island has few fossil fuel reserves, and it must import food and energy from abroad. That means when the yen weakens, ordinary folks see their bills shoot up.

The government employed a short-term fix: selling dollar reserves and buying yen to boost it. But Eurasia Group analyst David Boling says there’s not much to be done about the root of the problem.

“The yen’s weakness is being driven by the interest rate differential between the US, which has high interest rates and high bond yields, and Japan, which is very low,” he says. “Money is moving out of Japan to capture those higher yields.”

It might be another nail in the coffin for the PM, who could be replaced at the Liberal Democratic Party’s leadership conference this September.

“Japan has to have a lower house election by October 2025, and so the members of the LDP will be thinking about electing a leader who can take them through a national contest,” says Boling.

The Trump administration is reportedly considering a strategy to disrupt Iran’s oil exports by stopping and inspecting Iranian oil tankers at sea. The US would use the Proliferation Security Initiative, established in 2003 to prevent the trafficking of weapons of mass destruction, as a legal justification for the inspections.

The Energy Security Hub at the 2025 Munich Security Conference featured in-depth discussions on energy innovation, security, and market viability. Fatih Birol, IEA executive director, discussed growing global energy demand, especially the rapid rise in electricity outpacing overall growth. He noted electricity demand is projected to increase six times faster than total energy in 10 years, underscoring the need for electrification and grid expansion. As energy systems become decentralized and digitalized, the CEO of E.ON, Leonhard Birnbaum, said: “You’re either fully digitized – or you’re done.” Key takeaways: Energy security requires developing and securing electricity grids Technological openness is a unifying element for getting to net zero Bridge the “Valley of Death” to scale markets New global partnerships will help Europe stay competitive Public acceptance will strengthen democracy You can read the full Executive Summary from the BMW Foundation here.
