Rising bond yields add tens of billions to G7 countries' debt costs

Global bond yields have increased since the US war with Iran began in February, leading to an additional tens of billions of dollars in borrowing costs for G7 nations. An analysis of government bond issuance data by the Financial Times indicates that G7 countries have locked in an extra $16 billion in sovereign debt financing costs. The United States accounts for an estimated $10.6 billion of this increase to date, with a potential further $21.7 billion if the rise in yields persists until the end of the first quarter of 2027. This surge in yields is attributed to investor concerns over growing US public debt and inflation, which was triggered by the conflict.
