Bond Traders Warn of Inflation Shock as US Yield Curve Flattens

US bond markets are flashing a warning to US President Donald Trump that his move to unleash tariffs on top trading partners risks fueling inflation and stymieing growth.

Short-end Treasury yields rose as much as eight basis points to 4.28% on Monday as longer-dated rates held steady, flattening the curve by the most since November.

Such moves are typically associated with stagflation — when inflation and elevated interest rates harm bonds in the short term, only for subsequently weaker growth to make longer-term debt more appealing.

Traders have pared bets on the extent of easing from the Federal Reserve this year and now see a 50% chance of two quarter-point rate cuts this year, down from 90% on Friday.
