1 · Functions of the Financial System
The financial system includes markets and intermediaries that help transfer financial assets, real assets, and risks from one entity to another. People use the financial system for six main purposes.
Saving — move money from present to future via investments
Borrowing — obtain current funds with promise to repay
Raising equity capital — sell ownership interests for funding
Managing risks — hedge exposures using derivatives and insurance
Exchanging assets — spot market trading (currencies, commodities)
Information-motivated trading — profit from analysis of undervalued/overvalued assets
Facilitate the six purposes above
Determine rates of return — equilibrium interest rate equates aggregate savings with aggregate borrowings
Capital allocation efficiency — direct funds to most productive uses
Equilibrium interest rate: The rate at which aggregate savings equals aggregate borrowing/equity issuance. Required returns vary by risk, term, and liquidity — all depend on a common equilibrium rate plus adjustments for risk.
Investors move money forward in time; borrowers move it from the future to the present. The interest rate is the price of moving money through time.
Capital allocation efficiency — in well-functioning markets, only projects with value > cost are funded. Accurate market information is critical.
Information-motivated traders (active managers) seek returns beyond fair compensation for risk — they buy undervalued and sell overvalued assets.
2 · Assets, Contracts & Market Classifications
Financial assets, physical assets, and contracts are the building blocks of the financial system. Practitioners classify them by various characteristics.
Category | Examples | Key Characteristics |
|---|---|---|
Securities | Bonds, common stock, preferred stock, ETFs, mutual funds | Financial assets; may be public (registered) or private |
Currencies | USD, EUR, GBP, JPY, CHF | Monies issued by national monetary authorities; trade in FX markets |
Commodities | Gold, oil, agricultural products, carbon credits | Physical assets; trade in spot and futures markets |
Real Assets | Real estate, machinery, aircraft, timber | Tangible properties; illiquid, heterogeneous, costly to manage |
Contracts | Forward, futures, swaps, options, insurance | Agreements to exchange in the future; derivative if value depends on underlying |
Market classification dimensions: Primary vs Secondary · Spot vs Forward/Futures · Money vs Capital · Traditional vs Alternative · Public vs Private · Quote-driven vs Order-driven vs Brokered
Securities in Detail
Bonds, notes, bills, CDs, commercial paper, repos
Contractual payment schedules (interest + principal)
Money markets: ≤ 1 year maturity
Convertible bonds — can convert to stock
Common shares — residual ownership, voting rights
Preferred shares — priority dividends, usually no voting
Warrants — rights to buy issuer's stock at fixed price
Pooled Investments
Open-end funds — issue/redeem shares at NAV on demand
Closed-end funds — fixed shares; trade in secondary market at discount/premium to NAV
ETFs — trade like stocks; APs arbitrage to keep price near NAV
Hedge funds — limited partnerships; performance fees + leverage
Asset-backed securities — pools of mortgages, credit card debt, auto loans; tranches with different risk/return
Contracts
Forward — customized OTC; counterparty risk, illiquid
Futures — standardized exchange-traded; clearinghouse guarantees performance; daily margin settlement
Swaps — exchange periodic cash flows (interest rate, commodity, currency, equity)
Options — right (not obligation) to buy (call) or sell (put) at strike price; premium paid
Insurance contracts — pay benefit if specified event occurs (life, liability, CDS). Life settlements trade existing policies.
Physical vs financial contracts — physical: underlying is a physical product (oil, gold); financial: underlying is financial (index, currency, interest rate).
3 · Financial Intermediaries
Intermediaries connect buyers to sellers and facilitate the transfer of capital, risk, and assets. They are essential to well-functioning financial systems.
Intermediary | Role | Key Characteristics |
|---|---|---|
Brokers | Agents filling orders for clients; do not trade with clients | Reduce search costs; block brokers handle large orders; investment banks arrange offerings |
Dealers | Trade with clients for their own account | Provide liquidity; profit from bid-ask spread; can be broker-dealers (conflict of interest) |
Arbitrageurs | Profit from price discrepancies across markets or related instruments | Connect buyers in one market to sellers in another; provide liquidity; use replication strategies |
Securitizers | Pool assets and issue securities backed by the pool | Mortgage-backed, asset-backed securities; tranches with different risk profiles; SPVs/SPEs |
Depository Institutions | Banks, credit unions — take deposits, make loans | Transfer funds from savers to borrowers; subject to capital requirements |
Insurance Companies | Create insurance contracts to hedge risks | Pool risks; face fraud, moral hazard, adverse selection; use reinsurance |
Clearinghouses | Arrange final settlement; guarantee contract performance | Reduce counterparty risk; require margins; hierarchical system of responsibility |
Depositories/Custodians | Hold securities on behalf of clients | Prevent loss through fraud, oversight, disaster; often banks |
Key distinction — Brokers vs Dealers: Brokers arrange trades for clients (agency). Dealers trade with clients (principal). Broker-dealers do both, creating potential conflicts of interest.
4 · Positions: Long, Short & Leveraged
Own assets or contracts
Profit from price appreciation
Gains: unbounded; Losses: limited to 100%
Sell assets not owned (borrowed) or write contracts
Profit from price decline
Gains: limited to 100%; Losses: unbounded
Short seller must repay borrowed shares + dividends in lieu
Leverage Ratio = Value of Position / Equity Investment
Maximum leverage = 1 / Minimum margin requirement
Example: 40% margin → max leverage = 1/0.40 = 2.5
Equity per share = Initial equity + (P − Purchase price)
Margin call when: Equity per share / Price = Maintenance margin %
Example: Buy at $20, 40% margin ($8 equity), 25% maintenance:
($8 + P − 20) / P = 0.25 → P = $16
Total return on leveraged position = Leverage ratio × (return on unleveraged position) − interest costs − commissions
Short sale mechanics: borrow shares → sell → later buy back to return; proceeds held as collateral; short rebate rate paid on collateral
Option positions: Long call = long exposure; Short call = short exposure; Long put = short exposure; Short put = long exposure
5 · Orders & Execution
Orders specify instrument, quantity, side (buy/sell), and additional instructions: execution, validity, and clearing.
Execution Instructions
Fill immediately at best available price
Certain execution, but price may be uncertain
Can be expensive for large/illiquid trades
Fill at best price ≤ limit (buy) or ≥ limit (sell)
Better price on average, but may not execute
Aggressively priced = more likely to trade
Limit order terminology: Make a new market = improves the best bid/ask; Make the market = matches the best bid/ask; Behind the market = worse than current best; Marketable = crosses the spread and trades immediately.
Validity Instructions
Day order — expires end of trading day
Good-till-cancelled (GTC) — remains until filled or cancelled (broker may limit duration)
Immediate-or-cancel (IOC) — fills partially or fully, remaining cancelled; also called fill-or-kill
Good-on-close / Good-on-open — filled at closing or opening price
Step Orders
Stop-sell — becomes valid once price trades at or below stop price (often used as stop-loss)
Stop-buy — becomes valid once price trades at or above stop price
Stop-limit — combines stop trigger with limit price constraint
Stop orders can contribute to market momentum and often execute at poor prices
Clearing instructions: Indicate how to arrange final settlement — who is responsible (customer's broker, custodian, prime broker). For sales, must indicate long vs short sale and confirm deliverable securities.
6 · Primary & Secondary Markets
Issuers sell securities to investors
Funds flow to the issuer
IPO — first public offering
Seasoned offering — additional shares of previously issued security
Underwritten — investment bank guarantees sale
Best efforts — bank acts as broker, no guarantee
Private placement — to qualified investors; less disclosure
Rights offering — existing shareholders get rights to buy at discount
Shelf registration — sell shares over time
Investors trade securities among themselves
Funds flow between traders
Provide liquidity — investors can exit
Liquid secondary markets lower cost of capital in primary markets
Investors pay more for liquid securities
Higher prices = lower cost of capital for issuers
Market Structures
Structure | Description | Examples / Notes |
|---|---|---|
Quote-driven | Customers trade with dealers at quoted prices | Bonds, currencies, most spot commodities; OTC markets |
Order-driven | Rules match buy/sell orders; price and time priority | Exchanges, ECNs; uses uniform (call) or discriminatory (continuous) pricing |
Brokered | Brokers arrange trades among clients | Unique/infrequent instruments: large blocks, real estate, fine art, IP |
Call markets — trades only at specified times; single price auction; liquid when called but illiquid between sessions
Continuous trading markets — trades anytime open; more flexible but harder to find counterparties
Order precedence hierarchy: Price priority → Display priority → Time priority
Trade pricing: Uniform (call markets) — all trades at same price; Discriminatory (continuous) — standing limit order determines price; Derivative (crossing networks) — price from another market
7 · Well-Functioning Financial Systems & Regulation
Three types of efficiency:
• Complete markets — instruments exist to solve financial problems
• Operational efficiency — low transaction costs (commissions, spreads, price impact)
• Informational efficiency — prices reflect all available information about fundamental values
Informative prices lead to allocational efficiency — scarce capital flows to its most productive uses. Well-informed traders make prices efficient; liquid markets encourage informed trading.
Objectives of Market Regulation
Control fraud and agency problems (agents may not act in clients' best interests)
Promote fairness — e.g., insider trading prohibitions
Set mutually beneficial standards — e.g., common accounting standards (IFRS, US GAAP)
Prevent undercapitalised firms from taking excessive risks (capital requirements)
Ensure long-term liabilities are funded (insurance, pension reserves)
Self-Regulating Organizations (SROs): Exchanges, clearinghouses, dealer trade organisations that regulate their own members — either voluntarily or with delegated government authority — to promote confidence and reduce losses.
