German Finance Minister Christian Lindner has attributed the recent surge in global borrowing costs to the policies of former U.S. President Donald Trump. Lindner stated on Monday that Trump's aggressive policies, including the implementation of tariffs and his administration's involvement in various geopolitical conflicts, have destabilized the global economic order. This instability, according to Lindner, has contributed significantly to the highest borrowing costs seen in decades across major economies.

The minister's comments come as Germany's own borrowing costs have climbed significantly. German 10-year bond yields, for instance, have reached their highest level since 2011, and 30-year bond yields hit a 15-year high. Lindner emphasized that the need for massive investments in security and defense following Russia's invasion of Ukraine further necessitates significant government borrowing, which is now more expensive due to the prevailing high interest rate environment. Germany plans to borrow a total of $838.2 billion from 2027 to 2030, with interest payments projected to nearly double from $41.9 billion in 2027 to $80.7 billion by 2030.

Globally, other major Western economies, including the U.S. and Japan, have also experienced multi-decade highs in their bond yields. Analysts, such as Jonas Goltermann, chief markets economist at Capital Economics, suggest that investors are losing patience with fiscal profligacy, noting that the fiscal outlook in several major economies is problematic. The ongoing war in Iran, which has driven up oil prices and inflation, further complicates the situation, increasing pressure on government debt and overall borrowing costs for companies and households, and threatening to slow economic growth.
