The yield on 30-year U.S. Treasury bonds reached a 14-month high, affected by reports of Trump's tariffs and expansion pressure

The yield on the 30-year U.S. Treasury bond climbed by five basis points to around 4.86% on Monday, hitting its highest level since November 2023, as investors began to taste the potential turmoil that Trump's presidency could cause in financial markets over the next few months. The pressure of bond market expansion has had some impact on the market, with weak demand for the first batch of government bonds issued by the Treasury this week.

U.S. Treasuries have been under pressure in recent weeks due to fears that Trump's policies will drive up inflation after he takes office. After The Washington Post reported that Trump's staff were considering narrowing down tariff plans, the dollar fell on Monday and treasuries recovered some lost ground because markets believed this move would alleviate inflation concerns. However, with Trump's denial, market trends quickly reversed. Gregory Peters, co-chief investment officer at PGIM Fixed Income said in a television interview: "There are a lot of bonds in the market and supply is continuous; coupled with potentially stickier or rebounding inflation - all these put pressure on bond markets."
