Core Viewpoint - The article discusses the potential economic impacts and risks associated with the recently passed OBBB Act, which extends tax cuts and modifies tax policies in the U.S. economy, highlighting three main risks: financing risk, economic risk, and trust risk [1][5]. Summary by Sections OBBB Act Overview - The OBBB Act, passed by the U.S. House of Representatives on May 22, extends tax cuts from the 2017 TCJA Act, stabilizing tax policy expectations for individuals and businesses [2]. - The act is projected to increase the deficit by $2.3 trillion over the next 10 years, which is $900 billion less than earlier budget proposals, primarily due to significant cuts in welfare programs [2]. Deficit and Debt Implications - The act does not significantly alter the long-term trajectory of U.S. government debt, with a temporary increase in the deficit rate expected to exceed 7% before stabilizing around 6.5% [2]. - The arrangement of tax cuts preceding spending cuts may lead to uncertainties in actual deficit outcomes, as political motivations could affect the execution of spending cuts [3]. Risks Associated with the OBBB Act - Financing Risk: The act creates "untimely" pressure on U.S. debt supply, particularly before 2028, in a high inflation and high interest rate environment, potentially leading to mismatches in supply and demand for government bonds [5]. - Economic Risk: Certain tax reform provisions may exacerbate income inequality, as many tax cuts are extensions rather than new measures, which could lower expectations for economic stimulation [5]. - Trust Risk: New taxes on capital and labor entering the U.S. could undermine trust in the dollar system, potentially leading to a negative feedback loop affecting U.S. credit and economic recovery [5][4].
