Japan Bond Rout Deepens on Fears Over Takaichi’s Fiscal Package

Japan’s longer-maturity sovereign bonds tumbled further Tuesday as investor worries deepened that a big economic package from Prime Minister Sanae Takaichi would damage the nation’s public finances.

Yields on 40-year bonds jumped 8 basis points to 3.68%, their highest level since the securities debuted in 2007, while 20-and 30-year debt each rose at least 4 basis points. The 30-year yield is just a few basis points away from a record high.
