Executive summary

Fiscal stimulus under Biden — notably the $1.9 trillion American Rescue Plan — and the Federal Reserve’s aggressive rate hikes to combat the 2021–22 surge were the central forces shaping the post‑pandemic inflation episode [1] [2]. Under Trump’s 2025 administration, trade policy (large tariffs) and regulatory changes are the most frequently cited drivers of higher goods prices and recent inflation dynamics; officials credit deregulation and drug‑pricing deals with cooling some costs while critics point to tariffs and immigration limits as upward price pressure [3] [4] [5].

1. Biden’s big fiscal boost and the inflation spike

The defining fiscal action of the Biden era was the American Rescue Plan, a $1.9 trillion stimulus signed in 2021 intended to speed the COVID recovery; analysts and retrospectives link that large fiscal impulse to demand‑side pressure on prices that coincided with pandemic supply bottlenecks and global shocks such as the Ukraine war, helping drive CPI to a four‑decade high in 2022 [1] [2]. Reporting emphasizes that inflation “rose sharply” after the pandemic and that energy and food shocks amplified price rises, forcing the Federal Reserve to raise rates to cool demand [2]. Available sources do not mention other specific Biden fiscal items beyond the Rescue Plan in detail.

2. The Fed’s monetary tightening across administrations

All summaries in the reporting note the Federal Reserve’s central role: after inflation surged in 2021–22, the Fed lifted its benchmark policy rate repeatedly to slow demand — a standard monetary response that anchored much of the eventual downward movement in year‑over‑year inflation [2]. Sources contrast that with political arguments over who “caused” inflation, but they uniformly place rate hikes at the heart of the technical response; specific Fed rate paths are not detailed in the provided reporting [2]. If you want exact rate changes, available sources do not provide the Fed’s full chronological tightening table.

3. Trump’s trade and tariff strategy as a price lever

Reporting on Trump’s 2025 term highlights tariffs and trade policy as the administration’s primary levers that affect goods prices. Several sources document that new or higher tariffs — a universal 10–25% import tariff mentioned in analysis — put immediate pressure on consumer prices and are projected by some forecasters to raise average CPI growth into the coming years if they remain elevated [3] [4]. Journalists and economists quoted by AP and Reuters note that tariffs on goods are linked to higher prices for affected items and that goods subject to tariffs “cost more than before” [6] [3].

4. Political messaging vs. independent assessments

The White House under Trump credits the administration’s actions — deregulation, drug‑pricing deals, and other measures — with lowering costs and restoring purchasing power, and it cites recent drops in some metrics such as shelter inflation and mortgage rates as evidence [5] [7]. Independent outlets and fact‑checkers caution that whether inflation “eased” depends heavily on the measure: core inflation minus food and energy showed modest declines but headline inflation remained elevated around 3% at points in 2025 [8] [9]. Those differing framings reflect clear political incentives to claim credit or shift blame [5] [10].

5. Services, shelter and the shifting composition of inflation

Multiple sources observe that while tariffs act mostly on traded goods, services and shelter costs have been important drivers of inflation dynamics; Bessent and others argue services are the main ongoing pressure, complicating the claim that tariffs alone explain recent trends [4] [8]. The White House points to shelter inflation easing and falling median rent in recent months as favorable signs, but broader reporting shows consumer sentiment and affordability remain strained despite some headline improvements [5] [11] [12].

6. Forecasts, risks and competing scenarios

Economists cited in the reporting offer divergent forecasts: Deloitte and Moody’s scenarios show inflation could stay above the Fed’s 2% target if tariffs and immigration restrictions remain, while alternate scenarios without those policies predict a lower inflation path around ~2.25% through 2026 [3] [4]. Critics warn Trump’s policy mix risks reigniting price pressures even as administration officials argue their reforms will lower prices over time; polling and public frustration suggest political consequences regardless of technical measures [4] [12].

Limitations: the supplied sources emphasize high‑level actions and political claims rather than presenting full quantitative causal studies or complete Fed rate histories; detailed econometric attributions of how much each policy moved CPI are not in the provided reporting [2] [8].
