Understanding risk.
Types of financial risk and how to manage them.
Financial decisions involve risk. Compare the types of risk and the three responses, with links to relevant sections of the site.
Risk is not "the market might go down." Risk is any chance that reality doesn't match your plan. verify×DON'T TRUST, VERIFYClaim: Investor.gov defines risk as the degree of uncertainty and/or potential financial loss inherent in an investment decision.Verify at: SEC Investor.gov: What is Risk? ↗ Source 1 in the list belowThe SEC's investor-education page gives this definition and walks through business, volatility, inflation, interest-rate and liquidity risk, several of the eight types below. There are at least eight distinct types, you can only control three responses (avoid, retain, or transfer), and your capacity to bear risk is different from your willingness. Every page on this site is about managing one of these risks, this page names them all in one place.
Eight types of financial risk
| TYPE | WHAT IT IS | WHERE YOU SEE IT |
|---|---|---|
| Market | Asset prices fall | Bitcoin volatility, stock drawdowns |
| InflationinflationA general increase in prices over time, meaning each dollar buys less than it did before.Full definition | Purchasing powerPurchasing powerWhat money can actually buy, not the number on the bill or in the account. Inflation shrinks it over time: by the BLS consumer price index, it takes more than $8 today to buy what $1 bought in 1971. Same dollar, much less buying ability.Full definition erodes | Inflation types, the fiat problem |
| Longevity | Outliving your money | FIRE, withdrawal strategy |
| Sequence | Bad returns hit early in retirement | Sequence of returns |
| Concentration | Too much in one asset | Bitcoin allocation, diversificationdiversificationSpreading investments across different assets so a drop in one doesn't devastate your entire portfolio.Full definition |
| Counterparty | Someone you depend on fails | Self-custody, exchange risk |
| LiquidityliquidityHow quickly and easily you can convert an asset to cash without significantly affecting its price.Full definition | Can't sell without a loss | Private credit, real estate, illiquid alts |
| Tail | Rare, catastrophic events | Job loss, disability, currency collapse |
Three responses to risk
Every risk gets one of three treatments:
- Avoid. Don't take the risk at all. Don't invest in things you don't understand. Don't leave your emergency fund in the market.
- Retain. Accept the risk because the expected reward justifies it. Long-term equity investing retains market risk for about 6.8% a year after inflation (S&P 500 with dividends reinvested, compounded, 1928-2025). verify×DON'T TRUST, VERIFYClaim: The S&P 500 with dividends reinvested returned about 6.8% a year after inflation, compounded, from 1928 through 2025.Verify at: Damodaran, Historical Returns on Stocks, Bonds and Bills (NYU Stern, January 2026) ↗ Source 2 in the list belowDamodaran's table gives each year's S&P 500 total return; deflating each year by CPI-U inflation (his method, from FRED) and compounding 1928-2025 gives 6.77%. His own summary row shows 6.78%. Holding Bitcoin retains volatility risk for potential asymmetric upside.
- Transfer. Pay someone else to carry it. Insurance transfers disability risk, life risk, health risk. Diversification transfers concentration risk across assets.
Capacity vs tolerance
Risk capacity is how much loss you can financially survive, measured in months of expenses, years to retirement, income stability, and debt load.
Risk tolerance is how much loss you can emotionally handle without panic-selling. The two rarely match. Most people overestimate their tolerance until the first -40% drawdown. Your allocation should be set by capacity, tested by tolerance.
Risk across the site
Every section of this site addresses risk:
- Inflation, the risk that quietly erodes idle cash
- Bitcoin allocation, position sizing is risk management
- Bitcoin security, custody risk is the one you control directly
- Bond basics, bonds exist to dampen portfolio risk
- Disability insurance, risk transfer on your income
- Emergency fund, the fund is sized to the risk you're buffering
- Behavioral finance, most money mistakes are misjudged risk
