Is Japan's debt spiral becoming unsustainable?
Core argument: Japan’s 10-year yield hit 2.87%, its highest since 1996, as $2.3tn spending plans drive bond sell-offs and inflation concerns.
A bruising sell-off in Japanese government bonds this year pushed the country’s benchmark 10-year yield to 2.87% on Wednesday, its highest since 1996. Investors say the policies of Prime Minister Sanae Takaichi — centred on a $2.3tn spending plan spread over 14 years — are stoking the sell-off in long-term debt. Some also worry that the Bank of Japan, which raised interest rates to 1% last month, will fall behind the curve and let inflation rise above its 2% target. Market concern over long-term risks is reflected in the premium that investors are charging Japan to borrow for 10 years rather than two, which has risen from less than 1 percentage point in April to 1.4 percentage points today. This premium has recently been flat or falling in other big bond markets such as the US and Germany.
