Globally a firm U.S. dollar had the yen locked near a fresh 34-year low on Tuesday, keeping investors on heightened intervention watch as they looked ahead to key U.S. inflation report and the Bank of Japan's rate decision this week, Reuters reported.

The yen remained pinned after hitting 154.85 yen on Monday, its lowest level since the mid-1990s, as the stark U.S.-Japan rate differentials came into focus again amid an easing in Iran-Israel tensions. It last hovered around 154.76 per dollar.
