101PD SAMPLEChapter 1 — Money, Credit, and the Mortgage Economy California Real Estate Finance · 101PD Original Text · Professional training material. No statutory prelicensing credit is issued. Learning objectives. After this chapter you can: explain what money is and how credit expands it; describe the Federal Reserve's structure and each of its policy tools, and trace how a policy change reaches a buyer's mortgage quote; distinguish monetary from fiscal policy and explain how each moves housing; read the yield curve and the spread between the 10-year Treasury and the 30-year mortgage as a practitioner; explain inflation's double role as rate-driver and asset-driver; and narrate the real estate cycle — expansion, oversupply, recession, recovery — with the financing forces that push each phase. §1.1 Why a finance course begins with money Every real estate transaction is two transfers, not one: a deed moves in one direction and money moves in the other. Principles taught the law of the deed. This course teaches the law and machinery of the money — and that machinery begins far from the escrow table, in decisions made by a central bank about the price and quantity of credit. A licensee who cannot explain why rates rose between the listing appointment and the offer cannot counsel clients through the most rate-sensitive purchase of their lives. The chain runs: Federal Reserve policy → short-term rates and bank reserves → bond-market expectations → mortgage-backed-security yields → the rate sheet a loan officer prints in the morning → the buyer's maximum price → the seller's pool of qualified buyers → the comparable sales that set next quarter's appraisals. Finance is the study of that chain, link by link. Money itself performs three functions the exam and the practice both test: a medium of exchange (it settles transactions without barter), a measure of value (prices are quoted in it), and a store of value (it carries purchasing power across time — imperfectly, which is what inflation means). Modern money is fiat money: it is not backed by a commodity but by the taxing power and credibility of the government that issues it, and most of it exists not as currency but as ledger entries — bank deposits created by lending. §1.2 How banks create credit — the multiplier at the heart of mortgage lending When a bank receives a 100,000-dollar deposit and regulation or prudence requires it to hold a fraction in reserve, it lends the remainder; the borrower's spending becomes someone else's deposit; that bank lends again. Through this deposit-and-relend cycle, the banking system multiplies an initial deposit into a much larger stock of credit. Two practice consequences follow. First, credit availability is elastic: policy that changes reserves or the cost of reserves changes the lendable supply many times over, which is why housing — the most credit-dependent consumer market — feels monetary policy first and hardest. Second, confidence is collateral: because the system lends long (30-year mortgages) against liabilities it owes on demand (deposits), it depends on depositors
