U.S. Treasury yields surged and fluctuated in response to escalating inflation expectations and rate hike anticipation, driving a selloff in government bonds and impacting mortgage rates.

HSBC strategists warned that U.S. Treasurys had entered a "danger zone" as long-term yields climbed, with the 30-year Treasury yield reaching its highest level since 2014. Mortgage rates, typically tied to Treasury yields, also rose. Market participants priced in a higher probability of a Fed rate hike as soon as December, following surprisingly high inflation readings. The 10-year Treasury yield hit its highest level in 10 months, breaching 4.5% on Wednesday.

The volatility in Treasury yields strengthened the U.S. dollar, as better-than-expected economic data pushed yields higher. However, the breakdown of Iran-U.S. negotiations clouded the inflation outlook, causing yields to edge up further. Despite the yield surge, veteran strategist Ed Yardeni remained calm, viewing current yields as normal.

Watch for the Fed's next move and inflation data to gauge the trajectory of Treasury yields and mortgage rates. Upcoming catalysts include the Fed's June meeting (June 14-15) and the next Consumer Price Index (CPI) report (June 10).
