π° What Happened
Government bond markets are wobbling in major economies. The yield on 10-year US government borrowing hit 4.8% on Friday, up from 4.64% ten days earlier. At one point, the 30-year yield hit its highest level since 2008. UK gilts also reached multi-decade highs.
The trouble is spreading to borrowers. Mortgage rates are rising in the UK. Economists say markets are taking a fresh look at US public finances. Total US debt has surged past $40tn, with deficits near 6% of GDP forecast for years.
President Trump did not calm things down. Asked about rising rates on US debt, he said the ultimate intervention is the military. His restarted bombing campaign against Iran made bond markets worse.
π The Backstory
A government bond is basically a loan to a country. Investors buy them as a safe place to park money. The yield is the interest the government pays. When yields rise, governments must pay more to borrow.
For decades, big economies borrowed cheaply and investors rarely worried. That changed as debt piles grew and inflation returned. Central banks raised rates to fight inflation, which pushed bond yields up.
High yields ripple through the economy. They raise borrowing costs for homes, businesses, and governments. They can stall growth and keep inflation stubborn, leaving ordinary households to pay the price.
π― Why It Matters
Bond turmoil raises mortgage and loan costs for everyday people. It can also push up shop prices, as businesses pass on higher borrowing costs. When governments pay more to borrow, less money is left for schools, hospitals, and roads.
