The role of government and business in investments splits along a clear line: the government writes and enforces the rules that keep markets honest, protects your rights as an investor, and shapes economic conditions through interest rates and taxes, while private businesses take invested capital and turn it into products, jobs, and returns. Both sides depend on each other. Rules without productive companies produce nothing to invest in; companies without rules struggle to attract the capital they need.
How the Government Keeps Markets Honest
The federal government’s first job in the investment system is disclosure. Under the Securities Act of 1933, any company offering securities to the public must file a registration statement with detailed financial information so investors can decide what they are buying.1Office of the Law Revision Counsel. 15 USC 77g – Information Required in Registration Statement The Securities and Exchange Commission enforces those laws, investigating potential violations, filing hundreds of actions each year, and returning money to harmed investors.2U.S. Securities and Exchange Commission. Division of Enforcement Insider trading is one of its long-running enforcement priorities, with settlements against individual violators running into the hundreds of thousands of dollars or more.3U.S. Securities and Exchange Commission. SEC Enforcement Actions – Insider Trading Cases
Outside the securities markets, the Federal Trade Commission polices deceptive business practices. Federal law makes unfair or deceptive commercial practices unlawful and gives the FTC authority to investigate and file complaints against businesses that engage in them.4Office of the Law Revision Counsel. 15 USC 45 – Unfair Methods of Competition Unlawful Together, these enforcement bodies give you a reason to trust that the companies competing for your capital are playing by the same rules.
Standards That Protect You When You Invest Through Others
Most people don’t buy securities directly from an issuer. You go through a broker, an adviser, or a workplace retirement plan, and the government sets standards for each.
Broker-dealers work under Regulation Best Interest. When they recommend a securities transaction or investment strategy, they must act in your best interest and cannot put their own financial interests ahead of yours.5eCFR. 17 CFR 240.15l-1 – Regulation Best Interest They must disclose conflicts of interest, exercise reasonable care, and keep written compliance policies.
Registered investment advisers carry a broader obligation. Under the Investment Advisers Act of 1940, an adviser owes you a fiduciary duty combining a duty of care (advice must fit your specific goals) and a duty of loyalty (conflicts must be eliminated or fully disclosed so you can consent).6U.S. Securities and Exchange Commission. Commission Interpretation Regarding Standard of Conduct for Investment Advisers The practical difference matters. A broker’s recommendation must be in your best interest at the moment it is made; an adviser is on the hook for an ongoing relationship.
If your money sits in an employer-sponsored retirement plan, the manager works under a third standard. The Employee Retirement Income Security Act requires plan fiduciaries to manage assets solely in the interest of participants and beneficiaries, with the care and diligence of a prudent person familiar with such matters, and to diversify plan investments to minimize the risk of large losses.7Office of the Law Revision Counsel. 29 USC 1104 – Fiduciary Duties ERISA applies to employee benefit plans, not to institutional investors generally, so investments you hold outside a workplace plan fall under the broker and adviser standards above.
What Businesses Actually Do With Investment Capital
Businesses are where invested money becomes something. Companies take capital from shareholders and lenders and use it to build products, hire workers, and pursue markets. The government supports that work in two ways worth understanding as an investor, because they change what a company can afford to attempt.
The first is patent protection. Under Title 35 of the U.S. Code, an inventor who receives a patent gets the exclusive right to make, use, or sell the invention for a term ending 20 years from the date the application was filed.8Office of the Law Revision Counsel. 35 USC 154 – Contents and Term of Patent That exclusivity is what makes heavy research and development spending rational, because competitors cannot immediately copy the results.
The second is the Research Activities Credit under Internal Revenue Code Section 41, which allows businesses to claim a credit equal to 20 percent of qualified research expenses that exceed a base amount, or, alternatively, a simplified credit of 14 percent of qualifying expenses above a historical average.9Office of the Law Revision Counsel. 26 USC 41 – Credit for Increasing Research Activities Lowering the after-tax cost of R&D pushes more capital into innovation.
Where the Government Invests Directly
Beyond regulation, the government is itself an investor, funding projects that support commercial activity but lack the direct return private investors need.
Infrastructure
Federal spending funds highway, bridge, and port projects designed to improve the safety and efficiency of moving freight and people.10Office of the Law Revision Counsel. 23 USC 117 – Nationally Significant Multimodal Freight and Highway Projects Every business that ships a product depends on that network.
Clean Energy Credits
Public money also steers private capital into energy. Under Internal Revenue Code Section 48E, businesses that build qualifying clean electricity facilities can claim a base investment tax credit of 6 percent of their qualified investment. Meeting prevailing wage and apprenticeship requirements raises the credit to as much as 30 percent, with additional 10-percentage-point bonuses for meeting domestic content requirements or locating in an energy community.11Internal Revenue Service. Clean Electricity Investment Credit
Research and Small Business Capital
Agencies like the National Science Foundation pay for high-risk research that private companies rarely fund on their own. The NSF’s EAGER program, for example, supports exploratory work on untested but potentially transformative ideas, with awards of up to $300,000 over two years.12U.S. National Science Foundation. Opportunities for Early-Career Researchers – Funding at NSF Many technologies businesses later commercialize started in publicly funded university labs.
The Small Business Administration takes a different approach through the Small Business Investment Company program. SBA licenses private investment funds to receive government-guaranteed loans that match their privately raised capital. Those funds must invest in U.S. small businesses (generally those with a tangible net worth under $24 million and average net income under $8 million), and at least 25 percent of their investments must go to even smaller firms.13U.S. Small Business Administration.

How the Government Shapes the Investment Climate
The rules and direct spending are only part of the picture. Two broader policy tools set the conditions every investment decision runs into.
Interest Rates
Under the Federal Reserve Act, the Fed is directed to promote maximum employment, stable prices, and moderate long-term interest rates.14Board of Governors of the Federal Reserve System. Section 2A – Monetary Policy Objectives In practice, the Federal Open Market Committee adjusts its target for the federal funds rate, the rate banks charge one another for overnight loans, to move borrowing costs across the economy. Lower rates make loans cheaper for businesses and tend to lift investment activity; higher rates do the opposite.15Federal Reserve. The Fed Explained – Monetary Policy The Fed’s long-run inflation target is 2 percent, measured by the annual change in the personal consumption expenditures price index, because stable inflation lets households and businesses plan.16Board of Governors of the Federal Reserve System. Why the Federal Reserve Aims for 2 Percent Inflation Over the Longer Run
Corporate and Capital Gains Taxes
Taxes decide how much of a return actually reaches the investor. The federal corporate income tax rate is 21 percent of taxable income, set by the Tax Cuts and Jobs Act of 2017.17Office of the Law Revision Counsel. 26 USC 11 – Tax Imposed That figure shapes how much a company has left to reinvest or pay out.
For you as an individual investor, long-term capital gains (profits on assets held longer than one year) are taxed at 0 percent, 15 percent, or 20 percent, depending on taxable income and filing status.18Internal Revenue Service. Topic No. 409 – Capital Gains and Losses For 2026, the 15 percent rate begins at $49,450 for single filers and $98,900 for married couples filing jointly; the 20 percent rate applies above $545,500 for single filers and $613,700 for joint filers. Short-term gains, on assets held one year or less, are taxed at your regular income tax rate. That gap is why holding periods matter.
The Net Investment Income Tax
Higher-income investors pay an additional 3.8 percent tax on net investment income, including interest, dividends, capital gains, and rental income, under Internal Revenue Code Section 1411. It applies to the lesser of your net investment income or the amount by which your modified adjusted gross income exceeds $200,000 for single filers or $250,000 for married couples filing jointly.19Office of the Law Revision Counsel. 26 USC 1411 – Imposition of Tax Those thresholds are not adjusted for inflation, so more taxpayers become subject to the tax over time as incomes rise.
One Boundary: Foreign Investment Review
Not every investor gets an equal path in. The Committee on Foreign Investment in the United States reviews transactions where a foreign buyer could gain control of, or certain non-controlling interests in, a U.S. business that deals with critical technology, critical infrastructure, or sensitive personal data.20U.S. Department of Commerce. The Committee on Foreign Investment in the United States Filing is largely voluntary, but mandatory when a foreign government is acquiring a substantial interest in such a business. CFIUS also covers certain real estate transactions near military installations and other sensitive government sites.21U.S. Department of the Treasury. Final CFIUS Regulations Implementing FIRRMA If you are involved in a cross-border deal, checking whether a filing is required early can prevent a forced unwinding later.
The full picture is straightforward once you separate the two roles. Government sets the terms of the game and, through interest rates and taxes, changes the payoff for playing. Businesses take the capital and try to produce something worth more than they started with. Your returns, and your protections, come from both sides working at once.
