Macroeconomics for Investors
Fed, Central Banks, CPI, GDP

🌍 What is Macroeconomics and Why Should Investors Care?

Macroeconomics studies the economy at a large scale — growth, inflation, employment, interest rates, and exchange rates. Every investment decision is affected by these factors. For example, when the Fed raises rates, stocks typically fall, gold weakens, and the dollar strengthens — understanding the big picture helps you make better decisions.

🏦 Central Banks

Central banks are the "bank of banks" — they control interest rates and money supply. The three most important:

  • Fed (Federal Reserve) — the US central bank, the most influential because the US dollar is the world's reserve currency. FOMC meets every 6 weeks.
  • ECB (European Central Bank) — controls the euro.
  • BOT (Bank of Thailand) — controls the Thai baht. MPC meets every 6 weeks.

Main tool: Policy Interest Rate — raise it to fight inflation, cut it to stimulate the economy.

📈 Key Economic Indicators

CPI (Consumer Price Index)

Measures inflation. Most central banks target 2% per year. If CPI is too high, the Fed raises rates.

GDP (Gross Domestic Product)

Measures economic size and growth. 2-3% annual growth is healthy. Two consecutive quarters of negative GDP = Recession.

NFP (Non-Farm Payrolls)

The US jobs report, released on the first Friday of each month. Strong NFP → strong economy → stronger dollar → gold/stocks may fall.

PMI (Purchasing Managers' Index)

Measures business confidence. Benchmark: 50 = breakeven, above 50 = expansion, below 50 = contraction. A good leading indicator.

💰 Monetary Policy

Two main types:

  • Expansionary: cut rates, print money (QE) — stimulates the economy, stocks/gold often rise, currency weakens
  • Contractionary: raise rates, withdraw money (QT) — fights inflation, stocks/gold often fall, currency strengthens

Example: In 2022-2023 the Fed raised rates from 0% to 5.25% to fight inflation → tech stocks fell sharply.

🔄 Business Cycle

The economy moves through 4 phases:

  1. Expansion: GDP grows, employment strong, stocks rise — best for equities
  2. Peak: economy overheats, inflation rises — beware bubbles
  3. Contraction/Recession: GDP falls, layoffs, stocks drop — gold/bonds often outperform
  4. Recovery: central banks cut rates, economy improves — opportunity to buy stocks

🇹🇭 Thailand — What Thai Investors Should Watch

  • BOT Policy Rate — currently 2.00% (latest)
  • SET Index — the Thai stock market index
  • USD/THB exchange rate — strong baht = good for imports/foreign investing, weak baht = good for exports/tourism
  • Trade balance — Thailand is export-driven; trade balance affects the baht
  • Tourist arrivals — a major revenue source; impacts tourism/hotel stocks
