The Core Framework of Trump’s Economic Agenda
Since the campaign began, Trump’s economic policies have consistently revolved around three core elements: tax policy, debt management, and interest rate control. The ultimate goal of these three elements is highly aligned: to reverse the United States’ long-standing twin deficits in trade and the budget. Tariff and income tax reforms directly address the trade deficit, while the combination of debt and interest rate policies aims to alleviate pressure from the budget deficit. These three elements influence and depend on one another, forming a relatively comprehensive yet internally contradictory policy framework.
The Specific Logic Behind the Three Policy Pillars
Tax and Tariff Policies
Trump’s tax policy adjustments comprise two dimensions: first, domestic income tax cuts to lower corporate operating costs, aiming to attract the return of manufacturing to the United States; second, tariff barriers targeting major trading partners to reduce the trade deficit by raising the cost of imported goods. The core assumption of this policy combination is that tariffs can protect domestic U.S. industries, while tax cuts can boost corporate investment, ultimately achieving a balanced trade account.
However, this logic contains a clear inherent contradiction: tariffs increase the cost of imported raw materials and intermediate goods, which in turn weakens the international competitiveness of U.S. manufacturing; meanwhile, large-scale tax cuts directly exacerbate fiscal deficit pressures, requiring the issuance of more government bonds to bridge the budget gap—a move that would drive up interest rates and, in turn, suppress domestic investment.
Government Bond Issuance Strategy
The balance of the U.S. Treasury General Account (TGA) experienced two key turning points following the pandemic: the first occurred in early 2022, when the depletion of fiscal funds forced the U.S. government to issue bonds on a massive scale. Faced with insufficient overseas demand for long-term Treasury bonds, the U.S. Treasury opted to issue large volumes of short-term Treasury bills, which were primarily subscribed by domestic financial institutions and retail investors.
While this strategy alleviated fiscal pressure in the short term, it increased the risk of debt rollover in the long run. Given the short average maturity of short-term Treasury bills, interest rate fluctuations have a greater impact on debt servicing costs. Should interest rates rise in the future, the U.S. government’s interest expenses will balloon rapidly, further exacerbating the fiscal burden.
Interest Rate Policy Orientation
The rapid cycle of interest rate hikes that began in 2022 attracted massive inflows of foreign capital into the U.S., driving up the U.S. Dollar Index while also generating sufficient demand for U.S. Treasury bonds. However, high interest rates also exert downward pressure on the domestic economy, cooling the real estate market, raising corporate financing costs, and weakening economic growth momentum.
The Trump administration’s logic behind its interest rate policy was to attract global capital back to the U.S. through high rates, thereby funding U.S. Treasury bonds and domestic investment, while simultaneously using a strong dollar to lower import costs and partially offset the inflationary pressure caused by tariffs. However, the sustainability of this strategy is questionable, as high interest rates will ultimately undermine the U.S. economy’s own growth momentum.
Internal Contradictions and External Impacts of the Policy Framework
There is a clear tension among the three pillars of the policy framework: tax cuts and expanded fiscal spending require the issuance of more government bonds, while increased bond supply pushes up interest rates. High interest rates, in turn, raise debt servicing costs and suppress domestic investment, which in turn necessitates further tax cuts to stimulate the economy, creating a vicious cycle.
From a global perspective, Trump’s economic policies carry significant spillover effects. High interest rates attract global capital back to the U.S., leading to capital outflows and currency depreciation pressures in emerging markets; tariff policies disrupt global supply chain arrangements and drive up global inflation; and a strong U.S. dollar cycle will exacerbate global debt risks, placing significant pressure particularly on developing countries holding large amounts of dollar-denominated debt.
Key Points to Watch for Future Developments
The effectiveness of Trump’s economic agenda depends on several key variables: first, the capacity of the Treasury market to absorb new issuance, particularly whether overseas investors will continue to increase their holdings of U.S. Treasuries; second, the pace of interest rate policy adjustments and whether a balance can be struck between curbing inflation and supporting economic growth; and third, the retaliatory measures taken by major trading partners and whether these will trigger a global trade war.
At present, this policy mix may alleviate pressure on the U.S. twin deficits in the short term, but in the long run, it cannot fundamentally resolve the structural issues of the U.S. economy and may instead exacerbate global economic instability. Other economies need to prepare policy reserves in advance to cope with potential external shocks.
