FINRA $2,000 Minimum Initial Equity Requirement

An investor opens a new margin account and places an initial order to buy 100 shares of ABC stock at $30 per share ($3,000 total). Under Regulation T and FINRA rules, what is the required initial cash deposit?

Correct Choice: A

While Reg T 50% of $3,000 would be $1,500, FINRA Rule 4210 mandates an initial minimum equity requirement of $2,000 on margin purchases between $2,000 and $4,000.

Complete Analysis & Legal Rationale

FINRA's $2,000 minimum equity rule overrides Reg T whenever 50% of the purchase is less than $2,000. Therefore, the customer must deposit $2,000 (creating $2,000 equity and a $1,000 debit balance).

Mathematical Step-by-Step Derivation

  1. Step 1: Purchase Value = $3,000.
  2. Step 2: Reg T 50% = $1,500.
  3. Step 3: FINRA Minimum Equity Rule = $2,000.
  4. Step 4: Customer must deposit the GREATER amount: $2,000.

Distractor Autopsy (Why Other Options Are Traps)

FINRA exam writers design incorrect distractors using specific calculation mistakes and regulatory misconceptions. Review why each option succeeds or fails:

Choice ACorrect
Accurate Rule Application

Applies FINRA $2,000 minimum rule overriding Reg T $1,500.

Choice BIncorrect
Ignoring FINRA $2,000 Minimum

$1,500 is Reg T 50%, but it violates the FINRA $2,000 minimum equity floor.

Choice CIncorrect
Sub-$2,000 Rule Misapplication

100% deposit ($3,000) is only required if total purchase is UNDER $2,000.

Choice DIncorrect
Arbitrary Figure

Understates required deposit.
