Japan’s Super-Long Bond Yields Rise as War Fuels Inflation Fears

Japan’s super-long bond yields rose as the widening conflict in the Middle East pushed up oil prices and stoked inflation concerns.

The nation’s 30-year bond yield was up nine basis points to 3.79%, and the 40-year rate climbed as much as 11 basis points to 4.02%, both nearing record highs that were hit in January. Meanwhile, shorter-term bond yields fell alongside global peers on concerns that the Iran war will derail global economic growth.
