# Bank — Complete Banking Intelligence System

## What This Skill Does

Most people have the same bank account they opened as a teenager or young adult. They have
never seriously evaluated whether it is the right account for their current life. They pay
fees they do not need to pay, earn interest rates that round to zero when better rates are
available, and use products that were sold to them rather than chosen by them.

Banking is infrastructure. Bad infrastructure is invisible until it fails or costs you money.
This skill makes your banking infrastructure deliberate.

---

## Core Principle

A bank is not a relationship. It is a vendor. You are paying for services — either explicitly
in fees or implicitly in the spread between what they earn on your money and what they pay
you for it. The customer who evaluates banking decisions with this clarity consistently gets
better terms, pays less, and earns more than the customer who treats banking as a loyalty
relationship.

## Workflow

### Step 1: Assess the Banking Scenario
```
BANKING_SCENARIOS = {
  "account_optimization": {
    "goal":    "Ensure current accounts are the best available for actual usage patterns",
    "review":  ["Monthly fees paid", "Interest earned", "Features used vs available",
                "ATM costs", "Transfer fees"],
    "trigger": "Any time fees exceed $10/month or interest rate is below current HYSA rates"
  },
  "account_selection": {
    "goal":    "Choose the right account type for specific purpose",
    "types":   ["checking", "savings", "HYSA", "money_market", "CD", "business_checking"],
    "key":     "Match account features to actual usage — not to what sounds good"
  },
  "dispute_resolution": {
    "goal":    "Recover fees, resolve errors, escalate unresolved issues",
    "process": ["Direct request", "Formal complaint", "Regulatory escalation"],
    "success": "Most fee reversals are granted to customers who ask specifically"
  },
  "business_banking": {
    "goal":    "Separate business finances, build banking relationships, access credit",
    "needs":   ["Business checking", "merchant services", "business credit", "payroll"],
    "key":     "Business banking affects how lenders evaluate you — build it deliberately"
  },
  "international": {
    "goal":    "Minimize costs on cross-border transactions",
    "products": ["Multi-currency accounts", "international wires", "foreign ATM access"],
    "key":     "Traditional bank international fees are 3-5x what specialized providers charge"
  }
}
```

### Step 2: Account Architecture

The right banking structure separates money by purpose and ensures each dollar is held
in the account type that best serves its function.
```
ACCOUNT_ARCHITECTURE = {
  "checking": {
    "purpose":     "Daily transactions — bills, purchases, transfers",
    "what_matters": ["No monthly fee or easily waived", "ATM network or reimbursement",
                     "Mobile deposit", "Zelle or instant transfer"],
    "what_not_to_optimize_for": "Interest rate — checking balances should be minimal",
    "target_balance": "1-2 months of expenses — enough to avoid overdraft, not more"
  },

  "high_yield_savings": {
    "purpose":     "Emergency fund and short-term savings goals",
    "what_matters": ["APY as close to Fed Funds rate as possible",
                     "FDIC insured", "No minimum balance fee", "Easy transfer to checking"],
    "where_to_find": "Online banks consistently offer 4-5x the rate of traditional banks",
    "rate_reality": """
      Traditional big bank savings:  0.01% - 0.10% APY
      Online HYSA:                   4.50% - 5.25% APY
      Difference on $20,000:         $880 - $1,040 per year
      # This is free money left on the table by staying at traditional bank
    """
  },

  "money_market": {
    "purpose":     "Larger balances needing liquidity and higher rates",
    "vs_HYSA":     "Similar rates, often higher minimums, check-writing ability",
    "best_for":    "Balances over $50K where check-writing access has value"
  },

  "certificates_of_deposit": {
    "purpose":     "Fixed-rate return on money not needed for defined period",
    "CD_ladder":   """

                  "maturity": today + timedelta(months=months)

          # One CD matures every few months = liquidity + rate optimization
          return ladder
    """,
    "early_withdrawal": "Penalty typically 90-180 days interest — know before locking in"
  },

  "business_checking": {
    "purpose":     "Separate business and personal finances — legally and practically essential",
    "what_matters": ["Transaction volume limits", "Cash deposit ability if needed",

### Step 3: Fee Elimination
```
FEE_AUDIT = {

    },
    "ATM": {
      "typical":    "$2.50-$5 per transaction plus out-of-network fee",
      "eliminate":  "Choose bank with ATM reimbursement (Schwab refunds all ATM fees globally),
                     use cash back at grocery stores instead of ATM"
    },
    "wire_transfer": {
      "typical":    "$15-$35 domestic, $25-$50 international",
      "eliminate":  "ACH for domestic transfers, Wise or similar for international"
    },
    "paper_statement": {
      "typical":    "$2-$5/month",

### Step 4: Interest Rate Optimization

### Step 5: International Banking
```
INTERNATIONAL_FRAMEWORK = {

### Step 6: Banking Disputes
