——特朗普七大政策构想分析：美国民众能减负吗？

Policy Overview - Trump proposed seven key policies to address "Affordability" issues, including instructing Fannie Mae and Freddie Mac to purchase $200 billion in MBS to lower mortgage rates and limiting large institutional investors from buying homes to reduce prices[1][17]. - Other proposals include setting a credit card interest rate cap at 10%, issuing tariff rebates, requiring tech companies to cover infrastructure costs, a "Great Healthcare Plan," and banning dividends and buybacks for defense contractors while capping executive pay[1][11]. Feasibility Assessment - Two policies (MBS purchases and defense contractor restrictions) do not require congressional approval and have already begun implementation[4][29]. - Four policies may require legislation: limiting institutional home purchases, setting credit card rate caps, issuing tariff rebates, and the healthcare plan, which face potential opposition from both parties[3][6][35]. Probability of Implementation - Betting markets indicate a less than 45% chance for the implementation of limiting institutional home purchases, credit card rate caps, and tariff rebates within the year, with the highest probability (44%) for the credit card cap and the lowest (32%) for tariff rebates[2][7][42]. Potential Impacts - The MBS purchase could help narrow mortgage spreads, with estimates suggesting a potential reduction of 113 basis points in mortgage spreads if $200 billion is added[8][54]. - Limiting institutional purchases may only affect about 3% of the housing market, as institutions owning over 1,000 homes represent a small market share[2][56]. - A 10% cap on credit card rates could reduce rates by 11%, but the net interest margin for credit card businesses is only 9%-10%, potentially making the business unprofitable[9][12]. - Defense contractor dividends and buybacks account for 1%-3% of market value, with executive compensation linked to performance metrics rather than stock buybacks[12][22].
