The bond market has experienced a significant selloff, pushing a key Treasury yield close to 5%. This surge in borrowing costs is generating anxiety from Wall Street to Washington regarding its potential impact on the US economy.

Driving this concern are rising oil prices, which threaten a new inflation shock. Despite attempts by the Trump administration to alleviate pressure on the government debt market, the benchmark 10-year yield climbed to 4.97% by the end of last week. This level is just below the peak seen in October 2023, when the yield briefly exceeded 5% during a single trading session before attracting buyers and subsequently falling.

Further contributing to the bond market turmoil, investors are closely watching the Federal Reserve. While a rate hike this week would increase borrowing costs and potentially slow the economy, some investors warn that the bigger risk lies in the Fed choosing to hold rates steady. Such a decision could fuel a further selloff in bonds and push long-term rates higher for longer, as it might raise doubts about the Fed's commitment to its 2% inflation target. This uncertainty could lead investors to demand a larger term premium for holding longer-dated US debt, especially as government borrowing needs continue to grow.
