Investing.com -- Wolfe Research has raised concerns about the possibility of global central banks tightening monetary policy in response to higher oil prices stemming from the Iran conflict, according to a research note.

U.S. stock markets have not reacted to elevated oil prices, while long-term bond yields and central bank expectations in futures markets have moved in tandem with oil since the Iran conflict started, the firm said. This difference stems from America's energy independence compared to other regions, Wolfe Research noted.

Higher energy prices are expected to impact economic growth more substantially in Europe and Asia due to their greater dependence on energy imports, according to the research.

Several major central banks have held meetings over the past month, with Wolfe Research identifying potential for global central bank policy to differ from the Federal Reserve's approach, specifically global tightening versus the Fed maintaining rates or cutting them.

The Bank of Japan's recent policy board meeting showed a 6-3 vote in favor of holding rates, marking the largest division among members since Governor Ueda began his term in 2023. This split may indicate mounting pressure on the central bank to increase rates, though the extent remains uncertain, the firm said.

If the BOJ responds more forcefully to persistent inflation than futures markets currently anticipate, which price in approximately two rate hikes, a substantial strengthening of the Yen against the Dollar could trigger another carry trade unwind or market disruption, Wolfe Research warned.

The firm identified central bank policy errors, specifically tightening in response to temporary higher energy prices, and a carry trade unwind as the two primary risks that could halt the current market rally.
