**Deck**: U.S. 10-year and 30-year Treasury yields have surged to multi-decade highs, pushing mortgage rates above 7% and accelerating a historic bond selloff. Governments, homeowners and companies worldwide now face a more expensive era of debt as the benchmark for global borrowing resets in real time.

The world’s benchmark interest rate is lurching higher again, and this time the pain is showing up everywhere from Washington’s balance sheet to ordinary homeowners’ monthly bills.

On Thursday, the U.S. 10-year Treasury yield jumped past 5.15% as investors dumped government bonds, while the 30-year yield climbed to its highest level in roughly two decades. In practical terms, that move has pushed U.S. mortgage rates above 7% and signalled that cheap money, already fading, is slipping further into the rearview mirror.

Treasury yields matter far beyond Wall Street because they are the reference price for risk-free borrowing in dollars. When investors demand higher yields to hold long-term U.S. debt, the entire structure of global borrowing costs shifts upward. Governments pay more to fund deficits, corporations pay more to roll over bonds, and households pay more for long-term loans like home mortgages.

For American families on the edge of buying or selling a house, a 7% plus mortgage rate changes the math overnight. Monthly payments on a standard 30-year loan jump, pricing some first-time buyers out of the market and trapping existing owners who locked in ultra-low rates during the pandemic years. That can freeze housing turnover, slow construction and feed into wider economic anxiety.

For the U.S. government, higher yields translate directly into higher interest costs on a national debt that already exceeds $30 trillion. Each percentage point upward forces budget writers to carve out more room for debt service, squeezing discretionary spending and raising the political temperature around taxes, social programs and defense. The bond market is effectively forcing a conversation lawmakers have often tried to postpone.

The impact does not stop at U.S. borders. Emerging markets that borrow in dollars or benchmark their own bonds to Treasuries now face steeper refinancing cliffs. A government that once rolled over a 10-year bond at 3% might now confront rates more than two percentage points higher, with little warning. That can weaken currencies, raise default risk and push central banks to tighten policy just to keep up.

Companies with leveraged balance sheets feel the strain as well. Every refinancing round on corporate debt becomes more expensive, and projects that looked profitable at low rates may no longer clear the hurdle. For sectors from commercial real estate to private equity, the new yield environment is a direct test of which business models still work when money has a price again.

Strategically, a sustained period of elevated long-term U.S. rates would reorder capital flows. Investors may have less incentive to chase yield in riskier assets abroad if they can earn 5% or more on long Treasuries. That could undercut financing for frontier and developing economies while giving Washington more pull over global liquidity — at the very moment geopolitical competition is intensifying.

The question is no longer whether the era of near-zero rates is over, but how fast economies and political systems can adapt to the replacement. Signals to watch now include whether mortgage demand in the U.S. deteriorates further, how quickly Treasury auctions clear at these higher yields, and whether any major sovereign or corporate borrowers begin to struggle with rollovers. A disorderly auction, a surprise default, or a sudden policy shift by the Federal Reserve would be early signs that the bond market’s adjustment is moving from painful to dangerous.
