The long-term economic impacts of the policies implemented during the Roosevelt Recession were significant and far-reaching. The Emergency Appropriations Act of 1938 and the Fair Labor Standards Act of 1938, among others, not only provided immediate relief but also laid the foundation for sustained economic growth post-World War II. These policies helped stabilise the economy by increasing consumer purchasing power and creating employment opportunities. Furthermore, the recession and the subsequent policy responses contributed to a paradigm shift in economic thinking, ushering in an era where Keynesian economics – emphasising government intervention in managing economic cycles – became more widely accepted. This shift influenced future economic policies and played a crucial role in shaping the modern American economy.

International events and foreign policies had a notable impact on the Roosevelt Recession and its aftermath. The decline in global trade, exacerbated by the ongoing effects of the Great Depression and protectionist policies worldwide, negatively affected American exports, contributing to the economic downturn. Additionally, the approach towards international trade and relations during this period influenced the U.S. economy. The Reciprocal Trade Agreements Act of 1934, although not fully offsetting the downturn in global trade, represented an attempt to stimulate trade through bilateral agreements. Post-recession, the looming threat of World War II and the eventual involvement of the United States led to an increase in industrial production and military spending, which significantly boosted the economy and helped in its recovery from the recession.

The role of the Supreme Court during the Roosevelt Recession was primarily characterised by its relationship with New Deal legislation. Prior to the recession, the Supreme Court had struck down several New Deal measures, arguing that they overstepped federal authority. However, during the recession, there was a notable shift. The urgency of the economic situation and the growing public support for Roosevelt's policies led the Court to adopt a more accommodating stance. This change was partly due to the appointment of more sympathetic justices, as Roosevelt had the opportunity to nominate several new members. The Court's eventual acceptance and upholding of New Deal legislation during this period played a critical role in allowing the administration to implement its recovery strategies effectively.

During the Roosevelt Recession, public perception of the New Deal underwent a significant shift. Initially, there was a growing sense of disillusionment and criticism as the recession challenged the effectiveness of the New Deal policies. Many Americans began to question whether the government's intervention in the economy was truly beneficial, given the resurgence of economic hardship. However, as the Roosevelt administration responded to the recession with new policies and reforms, public confidence gradually restored. The administration's ability to adapt and address the economic downturn reinforced the belief in the necessity of government intervention during economic crises. This period solidified the New Deal's legacy as a transformative set of policies, despite the temporary setback posed by the recession.

The Roosevelt Recession had a profound impact on the political landscape in the United States. Initially, it provided a platform for Roosevelt’s critics, particularly from the conservative right, to challenge his policies and leadership. The recession stirred political debates on the extent of government intervention in the economy, with some advocating for a return to more laissez-faire policies. However, as the administration effectively responded to the recession, Roosevelt's political standing was strengthened, particularly within his own Democratic Party. The recession also led to a realignment in political allegiances, with more Americans supporting the Democratic Party due to its proactive approach to handling the economic crisis. This shift helped consolidate the New Deal coalition, which played a pivotal role in American politics in the subsequent years.
