Real vs Nominal: Plan in Today's Money, Not Future Money
Why Hyperinflation Is Never Just Money Printing — Expectations, Fiscal Collapse, and the Self-Reinforcing Spiral
Hyperinflation is never just "too much money printing" — it requires fiscal collapse, currency credibility loss, and self-reinforcing expectations that accelerate price rises beyond policy control. Here's how inflation expectations become self-fulfilling (the mechanism central banks obsess over), the TIPS break-even spread as a market inflation forecast, what Weimar Germany, Zimbabwe, and Venezuela share in common, and why fixed-rate mortgage holders actually benefit from unexpected inflation.
The CPI Basket Is a Political and Statistical Choice — Here's What That Means for the Inflation Number You See
CPI measures a basket of goods — but the basket's composition, weighting, and the mathematical formula used to average prices all involve significant methodological choices that produce materially different inflation readings. Here's how the basket is updated (and why the lag matters), the Laspeyres vs Paasche substitution bias problem, why chained CPI consistently reads 0.25% lower than unchained, and the UK alphabet soup of CPI vs CPIH vs RPI.
Your Personal Inflation Rate vs Headline CPI: Why "3%" and "My Bills Went Up 8%" Can Both Be True
"Inflation is 3%" and "my expenses rose 8%" can both be true at once — because official CPI is a weighted average across a standardized basket, and your spending pattern almost certainly doesn't match that average. Here's why housing-heavy, food-heavy, or energy-heavy budgets systematically diverge from headline figures, the shrinkflation and hedonic-adjustment perception gaps, and how to build a rough "personal inflation rate" using your own category weights.
Inflation Winners and Losers: Who Benefits and Who Loses When Prices Rise
Inflation transfers wealth from cash savers and fixed-income investors to fixed-rate debtors and real asset holders. Here's who benefits from inflation (property owners with fixed mortgages, governments with large debt), who loses (cash savers, bond holders, fixed-income retirees), and why these dynamics matter for portfolio construction.
How Central Banks Target Inflation: The 2% Target, Interest Rate Transmission, and CPI vs RPI
Central banks target 2% inflation — not because it's optimal, but because zero is dangerous. Here's why the 2% target emerged from New Zealand in 1989, how raising interest rates reduces inflation (with an 18-month lag), why CPI and RPI give different numbers, and what actually causes hyperinflation.
