The federal government shapes the U.S. economy through several distinct levers: it taxes and spends, sets interest rates through the Federal Reserve, controls what crosses the border and at what price, enforces competition among businesses, protects consumers in financial markets, funds public goods that private companies won’t build, sets minimum standards for wages and hours, and runs transfer programs that support people when the market falls short. The relationship between government and the economy runs through all of these channels at once, and federal spending alone accounts for roughly a quarter of GDP. Understanding each lever gives you a clearer picture of why prices move, how job markets shift, and what stands behind the financial news you read.
Taxing and Spending
The most direct lever is fiscal policy: how much the government collects in taxes and where it spends the money. The Internal Revenue Code in Title 26 of the United States Code sets the tax structure for individuals and businesses.1Office of the Law Revision Counsel. 26 USC 1 – Tax Imposed For 2026, individual income tax rates run from 10% to 37% across seven brackets, rates originally set by the 2017 Tax Cuts and Jobs Act and extended by legislation signed in July 2025. Corporations pay a flat 21% federal rate on profits. When Congress wants to stimulate activity, it can cut rates or expand deductions so households and businesses keep more of what they earn. Raising rates or trimming deductions works the other way, pulling money out of private hands.
On the spending side, Congress passes appropriations bills that authorize every dollar agencies actually spend.2Office of the Law Revision Counsel. 31 USC Ch. 11 – The Budget and Fiscal, Budget, and Program Information The President submits a proposed budget to Congress on or around the first Monday in February.3Treasury Financial Experience. Budgeting Because the federal budget is the single largest source of demand in the economy, that spending ripples outward: a defense contractor’s employees buy groceries, a highway crew rents hotel rooms, and the cycle continues.
When outlays exceed revenue, the Treasury covers the gap by selling bonds. The Congressional Budget Office projects the federal deficit for fiscal year 2026 at roughly $1.9 trillion.4Congressional Budget Office. The Budget and Economic Outlook: 2026 to 2036 Each annual deficit adds to the cumulative national debt, which reached $38.91 trillion as of May 2026.5Joint Economic Committee. National Debt Reaches $38.91 Trillion Congress sets a statutory ceiling on total borrowing under 31 U.S.C. ยง 3101 and periodically votes to raise it so the Treasury can keep paying existing obligations.6Office of the Law Revision Counsel. 31 USC 3101 – Public Debt Limit When those votes stall, the uncertainty alone can rattle markets.
Interest Rates and the Money Supply
Where fiscal policy runs through Congress, monetary policy runs through the Federal Reserve. The Federal Reserve Act gives the central bank a statutory mandate to promote maximum employment, stable prices, and moderate long-term interest rates.7Office of the Law Revision Counsel. 12 USC 225a – Maintenance of Long Run Growth of Monetary and Credit Aggregates The Fed operates independently of elected officials so its decisions reflect economic conditions rather than election-year politics.
The Fed’s primary tool is the federal funds rate, the interest rate banks charge each other for overnight lending. When the Fed raises that rate, borrowing gets more expensive across the board: mortgage rates climb, car loans cost more, and businesses hesitate to expand. When the Fed lowers it, cheap credit encourages spending and investment. The Federal Open Market Committee meets eight times a year to set the target range.
To adjust the money supply more directly, the Fed conducts open market operations. Buying government bonds from banks adds cash to the financial system and encourages lending. Selling bonds pulls cash back out and helps fight inflation. During the 2008 financial crisis and the 2020 pandemic, the Fed went further with quantitative easing, purchasing huge quantities of bonds to flood the system with liquidity when rate cuts alone weren’t enough. Its balance sheet ballooned as a result. More recently the Fed has been unwinding those holdings through quantitative tightening, letting bonds mature without replacement and reducing its portfolio by more than $2 trillion from peak levels.8Congressional Research Service.

Tariffs and Trade
The government also influences the domestic economy by controlling what crosses its borders and at what price. Tariffs are taxes on imported goods, and the President holds broad authority to impose them under several statutes, including Section 301 of the Trade Act of 1974, which targets unfair foreign trade practices.9Office of the United States Trade Representative. 2026 Trade Policy Agenda and 2025 Annual Report Trade agreements work the other direction, reducing barriers between partner countries to expand export markets for American businesses.
The effects cut both ways. By making imports more expensive, tariffs can protect domestic manufacturers and push companies to produce locally. They also raise costs for businesses that rely on imported materials, and those costs tend to reach consumers. Recent trade policy has focused on metals, semiconductors, energy, and pharmaceuticals, with the stated goal of rebuilding domestic production tied to national security. A steel tariff helps steelworkers in one region while raising costs for automakers in another, which is why trade policy is among the most politically charged economic tools.
Keeping Markets Competitive
A market economy depends on competition, and the government’s job is to keep any single company from rigging the game. The Sherman Act makes it a felony to conspire to restrain trade or to monopolize any part of interstate commerce. Corporations found in violation face fines up to $100 million, and individuals can be sentenced to up to 10 years in prison.10Office of the Law Revision Counsel. 15 USC 1 – Trusts, Etc., in Restraint of Trade Illegal; Penalty A separate provision targets monopolization specifically with the same penalty structure.11Office of the Law Revision Counsel. 15 USC 2 – Monopolizing Trade a Felony; Penalty
The Clayton Act blocks mergers and acquisitions that would substantially reduce competition or create a monopoly.12Office of the Law Revision Counsel. 15 USC 18 – Acquisition by One Corporation of Stock of Another It also addresses predatory pricing, tying arrangements, and other tactics companies use to squeeze out rivals.13U.S. Department of Justice. The Antitrust Laws When a major merger is proposed, the Department of Justice and the Federal Trade Commission review it to decide whether it would concentrate too much market power in one company’s hands. The Securities and Exchange Commission handles a related task, requiring public companies to disclose their finances so stock prices reflect reality rather than hype. None of these agencies set prices or pick winners; they enforce the conditions under which competition can actually work.
Protecting Consumers in Financial Markets
Competition law keeps businesses honest with each other. Consumer protection law keeps them honest with you. The Consumer Financial Protection Bureau, created after the 2008 financial crisis, oversees banks, lenders, and financial service companies. Its mandate covers unfair, deceptive, or abusive practices in consumer lending and includes a complaint process that has handled more than 6.8 million complaints to date.14Consumer Financial Protection Bureau. The CFPB CFPB enforcement actions have returned over $21 billion to consumers and produced more than $5 billion in civil penalties.
Credit reporting is another area where federal law reaches directly into your financial life. If a credit bureau has inaccurate information about you, the Fair Credit Reporting Act requires the agency to investigate your dispute and remove or correct unverified information, generally within 30 days. Errors on a credit report can raise your interest rates, block a mortgage, or cost you a job. The law puts the burden on the reporting agency to verify the data or delete it.
Financial regulation reaches well beyond individual complaints. Banking rules set capital requirements that prevent banks from over-leveraging, deposit insurance protects your savings if a bank fails, and securities law requires that investment products sold to you meet disclosure standards. The 2008 crisis showed what happens when those guardrails weaken, and the framework that followed aimed to make the system more resilient.
Building What Markets Won’t
Some things the economy needs won’t be built by private companies because there’s no practical way to charge individuals for using them. National defense protects every resident whether they pay or not. The interstate highway system, authorized by the Federal-Aid Highway Act of 1956, created a road network that made modern interstate commerce possible.15U.S. Government Publishing Office. Public Law 627 – Federal-Aid Highway Act of 1956 Public education produces a workforce that every employer benefits from.
Economists call these public goods because you can’t easily exclude people from using them and one person’s use doesn’t reduce the supply for everyone else. A private company won’t build a lighthouse and charge passing ships, because ships that don’t pay still see the light. Government funds these resources because the market has no mechanism to do it.
Infrastructure investment also acts as economic stimulus. Building a bridge creates construction jobs, workers spend their wages locally, and once the bridge opens, it lowers transportation costs for businesses on both sides. Federal and local governments invest in water systems, broadband networks, public transit, airports, and energy grids with that same dual purpose. When these systems deteriorate, the costs show up in delayed shipments, higher vehicle maintenance, and lost competitiveness.
Setting a Floor on Pay
The government also sets ground rules for the workplace that shape what you earn. The Fair Labor Standards Act establishes a federal minimum wage of $7.25 per hour, a rate in place since 2009.16Office of the Law Revision Counsel. 29 USC 206 – Minimum Wage Many states and cities set higher floors, so the rate you actually encounter depends on where you work.
The same law requires overtime pay at one and a half times your regular rate for any hours beyond 40 in a workweek.17Office of the Law Revision Counsel. 29 USC 207 – Maximum Hours Not everyone qualifies. Salaried workers earning above $35,568 per year who hold executive, administrative, or professional roles are generally exempt. A planned increase to that salary threshold was blocked by the courts, so the lower figure remains in effect for 2026.
Employers compete for workers above that floor, but they can’t go below it. When the minimum wage rises, employers often adjust pay for workers already earning slightly more, creating a compression effect that pushes wages up across lower-paying industries. Whether those increases lead to job losses or simply redistribute income remains one of the most debated questions in economics.
The Safety Net as Economic Stabilizer
When the market doesn’t provide enough income to cover the basics, federal programs fill the gap. The Social Security Act, codified at 42 U.S.C. Chapter 7, is the foundation for most of them.18Office of the Law Revision Counsel. 42 USC Ch. 7 – Social Security It authorizes retirement benefits, disability insurance, unemployment compensation, and assistance to families with children, among others.
Social Security retirement benefits pay a monthly check based on your earnings history and payroll tax contributions. For 2026, benefits rose by 2.8% through the annual cost-of-living adjustment.19Social Security Administration. Social Security Announces 2.8 Percent Benefit Increase for 2026 Nearly 71 million people receive these payments. Unemployment insurance, funded jointly by federal and state governments, provides temporary income if you lose your job through no fault of your own. Workers in most states can receive benefits for up to 26 weeks, though 16 states offer fewer weeks and the dollar amount varies widely. Nutritional assistance programs help low-income families afford groceries through an electronic benefit system.
These transfer payments act as automatic stabilizers for the wider economy. When unemployment rises during a recession, benefit payments increase automatically without any new legislation, pumping money back into local economies right when demand is falling. Retirees continue spending their Social Security checks regardless of what the stock market is doing. Social Security, Medicare, and Medicaid together account for the majority of federal spending, and their costs grow as the population ages. Funding those obligations over the long term is the central challenge of fiscal policy, because the commitments stretch decades ahead against revenue that fluctuates with the business cycle.4Congressional Budget Office.
