Japan’s rising yields are drawing record demand for retail government bonds, offering a potential new source of funding just as policymakers seek to contain borrowing costs and reduce market supply.

Retail bond sales climbed 84% year on year to a record ¥5.14 trillion ($33 billion) in the period from April to September, according to data compiled by Bloomberg.

The surge comes as market watchers question who will finance the nation’s borrowing as the Bank of Japan scales back debt purchases and inflation concerns drive up yields. While speculation has focused on whether the nation’s Government Pension Investment Fund will raise its allocation to domestic bonds, households sitting on ¥1.13 quadrillion worth of cash and deposits offer a potential new source of support.
