Hyman Minsky's financial instability hypothesis states that stability breeds instability: 'you can lead a banker to liquidity but you can't make them lend'—a banker with a bad balance sheet won't lend at any rate, and only late in the cycle when they're optimistic will they lend aggressively.

Interest rates are to housing demand as sticker shock is to sales: people look at monthly payment (achievable via subsidies) not the absolute price, so rate movements less important than headlines suggest; homebuilder financing subsidies can offset rate increases.

Behavioral macro framework analyzes markets through narratives, risk structure, and revealed preferences rather than economic theory, because actual behavior is narrative-driven (what people believe about the future), not theory-consistent.

For most people (non-professional traders), dollar-cost averaging with a diversified 60/40 portfolio and periodic rebalancing is superior to discretionary trading or stock picking because it removes behavioral error.

The JP Morgan quote 'nothing so undermines a man's financial judgment as seeing his neighbor get rich' explains why lenders are willing to lend at lower rates during booms—it's not about the rate level but about fear of missing out and competitive pressure.

Late-cycle speculation (people expecting 200-300% returns on houses or coins) is insensitive to whether Fed funds is 1%, 3%, or 5%—the absolute rate level becomes trivial compared to expected return.

Mortgage spreads (e.g., 40-130 basis points depending on market) don't meaningfully change buying decisions: the married couple wanting to leave the city or needing more space won't delay purchase because spreads widened 40bp.

The Federal Reserve does not control the quantity of money; chartered banks and shadow banks create the bulk of money supply. Banks can create money by lending without requiring reserves, only needing to stay within capital and liquidity ratios. The Fed only controls reserves in the settlement system.

The Fed's late start to hiking (beginning in March 2022 vs earlier) was actually justified given the transitory shock hypothesis, because multiple supply shocks (COVID, Delta, ports, Russia) meant you didn't know if tightening would help; waiting to see if inflation self-corrected was rational policy.

Japan has higher debt-to-GDP (higher than US), zero inflation problem, and no crisis despite this high debt, proving that high debt levels alone don't force either inflation or crisis if you're the reserve currency.

The yield curve inversion was not a reliable signal of recession in the modern financial system because maturity transformation has changed: via swaps and derivatives, a bank can borrow and lend at the same maturity (e.g., both at the 10-year point), eliminating classic interest-rate-risk from inverted curves.

For distressed companies with highly uncertain cash flows, the discount rate (Fed policy) doesn't matter at all; you only care about binary 'will they survive' questions. This proves the finance principle: discount rate relevance is inversely proportional to cash flow uncertainty.

Apple's growth rate slowdown matters more to its stock price than 300 basis points of rate increases, because the uncertainty is in the growth rate, not the discount rate.

The GFC recovery was slower than the COVID recovery because the GFC relied entirely on monetary stimulus (weak) without adequate fiscal support, while COVID had both (strong). This historical comparison proves fiscal is the powerful tool, not monetary.

Risk management is more important than fundamental correctness for trading success; being right on thesis but wrong on timing/leverage can wipe you out, whereas being wrong on thesis but right on stops can leave you profitable.

Fiscal stimulus in response to the COVID shock filled a 'hole' in aggregate income, which prevented hysteresis (permanent loss of productive capacity). Overfilling the hole slightly (creating 1-2% extra inflation per year) was worth the cost of preventing permanent supply-side damage.

The 2007-2023 period's lack of housing supply shortage recovery was not about Fed policy but about three factors: supply constraint from GFC hangover, post-COVID supply demand shock (people moving out of cities), and structural building constraints. Fed funds rate is almost irrelevant to total housing supply.

The 2000 tech bubble had the highest valuations in Mark's lifetime with Fed funds at 5% and 10-year at 7%, and the 2008 financial crisis featured the highest quantity and worst quality of mortgages during the three preceding years when Fed funds was at 5% average, yet we call the Fed rates 'easy' in hindsight.

The post hoc ergo propter hoc fallacy is rampant in financial analysis: people observe 'this happened and then that happened' and conclude 'this caused that' without considering alternative causes, particularly with QE where timing is confounded with other economic factors.

Monetary policy matters less than people think because it gets swamped by other factors like behavioral/animal spirits, fear, greed, and economic expectations, particularly in a globalized financial system with shadow banking.
