The U.S. dollar moves in both directions amid renewed attacks involving Iran, with market sentiment wavering as investors reassess risk and potential energy-price impacts. According to the reports, the dollar initially strengthens as Middle East tensions raise concerns about higher oil and energy costs, which can revive global inflation expectations. However, the dollar then pares gains, indicating uncertainty about how long the heightened geopolitical risk will affect prices and monetary expectations.

In parallel, the Japanese yen weakens. One outlet links the yen’s decline to doubts over Japan’s pension situation, which can weigh on demand for yen assets and contribute to broader currency weakness. The overall picture presented across sources is that currency markets react to a combination of geopolitical developments and domestic fiscal or financial concerns in Japan, while inflation fears tied to energy prices continue to influence trading.

The reports describe a market that is sensitive to news flow from the Middle East and to shifting views on inflation, but they do not cite specific policy moves or central-bank actions driving the moves.
