30年期美债收益率持续拉升，“债市义勇军”密切关注“美丽大法案”和“X日”因素

Core Viewpoint - The focus of U.S. Treasury investors has shifted from optimism regarding trade relations to concerns about the U.S. fiscal trajectory, particularly following Moody's downgrade of the U.S. government credit rating, which is expected to lead to an increase in Treasury yields [1][3]. Group 1: Treasury Yields and Market Reactions - The Wells Fargo strategist team predicts that the 10-year and 30-year U.S. Treasury yields will rise by 5 to 10 basis points due to the impact of Moody's downgrade [1]. - The 30-year Treasury yield has already reached 5%, marking the highest level since November 2023 [2]. - The bond market is closely monitoring developments in Congress regarding the proposed "Big, Beautiful Bill," which could significantly increase the already high debt level of $36 trillion [3]. Group 2: Fiscal Policy and Debt Concerns - The proposed "Big, Beautiful Bill" could add trillions to the national debt, raising concerns among bond market participants about fiscal responsibility [3]. - Analysts suggest that the downgrade of U.S. debt ratings is not surprising given the ongoing fiscal expansion, which may lead large investors to shift away from U.S. Treasuries to other safe-haven assets [3]. - The nonpartisan Committee for a Responsible Federal Budget estimates that the proposed legislation could increase U.S. debt by approximately $3.3 trillion by 2034, or up to $5.2 trillion if temporary measures are extended [3]. Group 3: Urgency of Debt Ceiling Resolution - The U.S. Treasury Secretary is urging Congress to raise the federal debt ceiling before mid-July, as the government may reach a critical "X date" by August when it can no longer meet its obligations [5]. - Concerns about the debt ceiling are already being reflected in the yields of Treasury securities maturing in August, which are higher than those of securities maturing at other nearby dates [5]. - There is a consensus among Republicans to extend the tax cuts from 2017, but disagreements remain on how to offset the loss in tax revenue through spending cuts, which are limited due to mandatory spending commitments [5].
