Economics
Economics explains the forces that shape our financial world. Understanding inflation, interest rates, GDP, and market cycles helps you make better investment decisions, anticipate economic shifts, and protect your wealth. You don't need an economics degree — our plain-language guides make macro concepts actionable.
Key Concepts
These fundamental economic concepts directly affect your money and investment decisions.
Inflation
Rising prices that erode purchasing power over time. The Fed targets 2% annual inflation. Real returns = nominal return minus inflation.
Interest Rates
Set by the Federal Reserve, interest rates influence everything — from mortgage rates to stock valuations to savings account yields.
GDP
Gross Domestic Product — the total value of goods and services produced. Two consecutive quarters of declining GDP = recession.
Supply & Demand
The fundamental economic force. When demand exceeds supply, prices rise. When supply exceeds demand, prices fall.
Business Cycle
Economies move through expansion, peak, contraction, and trough phases. Understanding cycles helps time major financial decisions.
Monetary Policy
How central banks (like the Federal Reserve) manage money supply and interest rates to achieve economic goals.

What Is Inflation? How It Affects Your Money and Investments
Understand inflation, how the Fed measures it, what causes it, and most importantly how to protect your wealth from it.
How Interest Rates Work and Why They Matter to Your Finances
From the Federal Reserve to your savings account and mortgage — understand how interest rates affect every part of your financial life.
Learning Roadmap
Understand inflation and how it affects you
Inflation erodes cash savings. $100,000 at 3% inflation is worth $74,000 in 10 years. Investing is a necessity, not just an option.
Learn how interest rates work
When the Fed raises rates, bonds fall, growth stocks drop, and savings rates rise. Understanding this is critical for investors.
Understand the business cycle
Different asset classes perform differently in each phase of the economic cycle. Diversification protects through all phases.
Learn to read economic indicators
Follow CPI (inflation), unemployment rate, GDP growth, and yield curves for macro context.
Understand global markets
The US economy is deeply interconnected with global markets. Diversify internationally to reduce country-specific risk.
Frequently Asked Questions
How does inflation affect my investments?
Inflation reduces the real value of cash and fixed-income investments. Stocks, real estate, and TIPS (Treasury Inflation-Protected Securities) historically outpace inflation. The goal is to earn a "real return" — your return above the inflation rate.
What happens to stocks when the Fed raises interest rates?
Higher rates increase borrowing costs for companies, reducing earnings. They also make bonds more attractive relative to stocks. Growth stocks (valued on future earnings) are hit hardest. However, rising rates often come with a strong economy, which is a positive for stocks overall.
What causes a recession and how should I prepare?
Recessions are caused by various factors: excessive debt, asset bubbles, supply shocks, or loss of confidence. Prepare by maintaining an emergency fund (6+ months), diversifying investments, avoiding excessive debt, and staying invested through downturns — market timing almost always backfires.
What is quantitative easing (QE)?
When the Fed buys bonds and other assets to inject money into the economy and lower long-term interest rates, especially when short-term rates are already near zero. QE increases the money supply, which can stimulate growth but also contribute to inflation and asset price inflation.
