Personal & Business Finance – In-Depth Study Notes

FDIC Protection & Basic Account Types

  • Federal Deposit Insurance Corporation (FDIC)

    • Federal agency that guarantees deposits in member U.S. banks up to 250 000250\,000 per depositor, per ownership category, per bank.
    • If your cash exceeds 250 000250\,000, simply open additional accounts (or use multiple banks) to keep each balance under the limit.
    • Purpose: Consumer confidence – banks do occasionally fail.

  • Core retail bank products

    • Savings account – “safe parking spot” for cash; very small interest (≈ 0.04%0.04\% APY typical example mentioned).
    • Checking account – transactional account used to write checks, pay bills online, or use a debit card; usually earns negligible or no interest.
    • High-yield online savings (e.g.Synchrony) – offers rates closer to 4%4\% in current market, but still FDIC-insured.

Certificates of Deposit (CDs) & Interest-Rate Mechanics

  • CD = Certificate of Deposit (time deposit)
    • You commit funds for a fixed term (3 mo, 6 mo, 1 yr, 5 yr, 10 yr, …).
    • Bank pays higher interest than a regular savings account because it can safely lend those locked-up funds (mortgages, auto loans, corporate loans).
    • If you redeem early you pay a penalty (forfeited interest).
  • Profit source for bank = spread between what it pays CD holders and what it collects on loans.
  • Importance of understanding interest:
    • Compounding, APR vs APY, fixed vs variable rates.

Business Loans: Short-Term vs Long-Term

  • Short-term business loans
    • Maturity ≤\le 1 year.
    • Supply working capital, inventory financing, or bridge a seasonal cash gap.
  • Long-term business loans
    • Maturity > 1 year (can be 5–30 yrs).
    • Fund buildings, warehouses, heavy equipment.
  • Home-equity loan analogy for individuals: borrow against built-up property equity.
  • Interest-rate structures
    • Fixed – unchanged for life of loan.
    • Variable/adjustable – resets with market benchmark (e.g.SOFR, Prime).

Credit Cards vs Debit Cards

  • Debit card

    • Linked directly to checking/savings; purchase amount debits immediately.
    • Functions like electronic cash; usually also ATM card.
    • Security: PIN requirement, bank fraud policies, ability to get cash back at point of sale.
    • Pros: no interest, encourages budget discipline.
    • Cons: declined if insufficient funds; possible overdraft fees if opt-in.

  • Credit card

    • Card issuer pays merchant; you repay issuer later (short-term loan).
    • Grace period: if balance paid in full each cycle, Interest=0\text{Interest} = 0.
    • Benefits: builds credit history, emergency liquidity, rewards (cash-back, miles, hotel nights), purchase protection, travel insurance, stronger charge-back rights, fraud protection limits.
    • Risks: late fees, penalty APR, credit-score damage, overspending, high average APR (≈ 25%25\% typical), over-limit fees.

  • Practical advice from lecturer

    • Start early to build credit history (students often approved for $3 000\$3\,000 limit; <18 requires co-signer).
    • Prefer cards with 00 annual fee + at least 2%2\% cash-back.
    • Pay entire balance monthly; avoid carrying debt except true emergencies.

U.S. Credit-Card Statistics Shared

  • Average American holds 3.43.4 credit cards.
  • 76%76\% of U.S. adults own at least one card.
  • Roughly 50%50\% carry a revolving balance (credit-card debt). High interest exacerbates hardship, esp. around holidays.

Retailer Card-Processing Fees

  • Merchant services fee ≈ 3.5%–4%3.5\%\text{–}4\% of transaction value on credit cards.
  • Some stores:
    • Offer cash or debit discount price.
    • Add explicit surcharge for credit-card usage (<$15 flat 1.251.25 fee example cited).

International Trade Finance Instruments

  • Letter of Credit (L/C)

    • Bank guarantees exporter will be paid once shipment documents match pre-agreed criteria (quantity, quality, date).
    • Solves importer-exporter trust problem (“who ships/pays first?”).

  • Banker’s Acceptance

    • Time draft accepted by a bank promising payment of a specified amount on a stated future date; can be traded on secondary market.

Personal Wealth-Building: Mortgages, Equity & Investing

  • Typical Miami one-bedroom ≈ $300 000\$300\,000.

    • Consumers rarely save entire price → need mortgage.
    • Down-payment typically 20%20\% unless first-time-buyer programs allow less.
    • Over time, payments build equity (ownership stake).

  • Rent ≠ wealth: renters pay landlord’s mortgage.

  • Excel amortization schedule reveals: early payments mostly interest; principal portion grows over time.

  • Refinance tips

    • Never sign predatory loan locking you in; ensure no prohibitive prepayment penalty.
    • Weigh fixed vs variable rate depending on macro outlook.

  • Broader investing philosophy

    • Salary alone seldom creates wealth; invest surplus in stock market, CDs, real estate.
    • Even $50\$50–$25\$25 monthly contributions accumulate via compounding.
    • Live below means – “not how much you make, it’s how much you keep.”

Financing Terminology & Short-Term Funding Vehicles

  • Unsecured financing – no collateral (e.g.credit cards, unsecured lines of credit).
  • Secured financing – backed by collateral (mortgage, auto loan, inventory loan).
  • Trade credit – seller allows buyer 3030–6060–4545 days to pay invoice; extended once trust established.
  • Promissory note – written IOU specifying amount & due date.
  • Commercial paper – short-term promissory notes issued by large corporations (typical maturity 270 days or less).
  • Compensating balances – lender requires borrower to keep minimum deposit with bank as part of unsecured loan agreement.
  • Factoring/Receivables financing – borrow against A/R; lender may advance ≈ 50%50\%–80%80\% of face value.

Raising Capital: Stocks, IPOs & Venture Capital

  • Corporation can issue stock; selling ownership slices raises equity capital.
  • Initial Public Offering (IPO) – first sale of shares to public (NYSE/Nasdaq, etc.).
    • Examples: Airbnb, DoorDash, Warner Music, Zoom, Facebook, Alibaba, Google, Spotify, WhatsApp.
  • Venture Capital (VC)
    • Professional investors provide early-stage funding for high-growth startups.
    • Miami ecosystem: Wynwood & downtown hubs; “eMerge” conference; city ranked #13 nationally for VC inflow post-COVID.

Alternative Funding: Crowdfunding & SPACs

  • Crowdfunding
    • Raise small amounts from large crowd via platforms (Kickstarter, GoFundMe).
    • Used for charity/emergencies & also startup pre-sales/equity (regulated JOBS Act portals).
  • SPAC (Special Purpose Acquisition Company)
    • “Blank-check” shell that IPOs, then hunts for a private firm to merge with.
    • Celebrity-backed examples: Donald Trump’s venture, Justin Timberlake, Kendall Jenner, A-Rod, Shaquille O’Neal, Snoop Dogg.
    • Empirical data: post-merger performance often under-performs traditional IPOs; considered higher risk (“buyer beware”).

Macro-Economic Context & Policy Implications (U.S.)

  • U.S. national debt now exceeds GDP\text{GDP} ("we owe more than we produce").
  • Federal budget interest payments are 3rd-largest line item (after Social Security & Medicare/Medicaid), surpassing defense spending.
  • Bond-market shift: recent auctions show weaker demand → could force higher Treasury yields.
  • Possible consequences
    • Higher future taxes to service debt.
    • Rising interest-rate environment → variable-rate borrowers face larger payments.
    • Importance of fixed-rate financing & prudent debt levels.

Best Practices & Ethical / Practical Take-aways

  • Separate business and personal bank accounts to maintain clear cash-flow history and improve loan eligibility.
  • Consolidate debts where possible; fewer bills = easier management.
  • Avoid late fees ("throwing $20\$20 out the window").
  • Treat credit card as free 30-day loan — only if balance is paid in full.
  • Be skeptical of “too good to be true” investment pitches (pyramid schemes, unrealistic returns).
  • Understand legal capacity: under 1818 cannot be held liable for contracts → need adult co-signer.
  • Maintain liquidity: “Cash is king” for both households & firms; avoid exhausting cash on single big asset purchase.
  • Use financial calculators (Excel amortization templates, online mortgage calculators) before major commitments.
