What the Customer Protection Rule Actually Requires

The Customer Protection Rule (Exchange Act Rule 15c3-3) exists for one specific reason: to stop broker-dealers from using your money to run their business. Here is how the rule works and how Curvature broke it for eight months.

• Every registered broker-dealer must maintain a dedicated “reserve account” funded with customer money. The amount required is calculated weekly using a specific formula: tally up everything the firm owes customers (credits), subtract what customers owe the firm (debits), and deposit the difference.
• If the reserve account is underfunded, the firm is technically operating with a customer-protection gap. In a sudden insolvency scenario, customers would be first in line to feel that gap.
• A “hindsight deficiency” is the formal term for discovering, after the fact, that a prior week’s deposit was too small. Curvature logged 27 of them in a single eight-month stretch.
• The individual deficiencies ranged from $20,906 to $6,846,329. The largest single underfunding was nearly $6.9 million. The combined total across all 27 deficiencies was $29,233,133.
• The trigger was a data pipeline problem. Curvature was using a data source that excluded the “short market values” of customer securities from the reserve calculation. Short positions affect the reserve formula, and excluding them produced a consistently deflated required-deposit number.
• The firm ran this flawed calculation 32 times before anyone identified and corrected the error. Five of those 32 calculations did not produce a documented hindsight deficiency; 27 did.

The Non-Financial Ledger

The documents in this case are written in the language of compliance. “Hindsight deficiencies.” “Books and records violations.” “FOCUS report inaccuracies.” That language is designed to make what happened feel technical, abstract, and ultimately minor. It is not minor.

The Customer Protection Rule exists because of what happened in the 1960s, when broker-dealers across the United States collapsed and left their customers with nothing. People who thought their savings were held in trust found out the hard way that their broker had commingled, gambled, or simply lost their money. The rule Curvature broke was written in direct response to that wreckage. It is one of the most fundamental investor protections in American financial law.

Every week that Curvature ran its flawed calculation, the reserve account meant to protect customer assets was short of where it legally had to be. For the week with the worst deficiency, the gap was nearly $6.9 million. If, during that exact week, Curvature had failed, the money that was supposed to be ring-fenced and waiting was not fully there. That is the entire scenario the law was written to prevent.

The customers of Curvature Securities were not told any of this. They received no notice that the mathematical foundation of their account protection had been broken for eight months. They had no idea that the weekly calculation ensuring their assets were safeguarded was being run on incomplete data. They trusted a system, and the system quietly failed them, week after week, while the error went undetected.

The corrective action statement Curvature attached to this settlement reveals something telling. The mandatory controls now being put in place, including mandatory presidential review of formula changes and weekly sign-off meetings between the firm’s financial officer and compliance staff, did not exist before this happened. These are not exotic safeguards. These are basic oversight mechanisms. Their absence for an eight-month period at a firm handling customer funds is a window into how lightly some corners of financial services treat the foundational rules that exist to protect ordinary people.

FINRA’s $50,000 fine lands as approximately 0.17 cents for every dollar the reserve was short. No customer compensation. No admission of wrongdoing. A censure that lives in a database. The firm’s Chief Compliance Officer, Todd Pigott, signed the settlement. The firm’s legal team, Sullivan & Worcester LLP, negotiated it. By February 6, 2025, it was done. The story was closed before most of Curvature’s customers ever knew there was a story at all.

Societal Impact Mapping

Public Health of the Financial System

This case documents a structural failure in the safeguards designed to protect ordinary investors from broker-dealer insolvency. The documented harms extend beyond Curvature’s clients.

• The Customer Protection Rule is the core mechanism preventing a repeat of the 1960s broker-dealer collapses that wiped out retail investors. Each firm that fails to accurately maintain its reserve weakens the operational integrity of that system, even if no insolvency occurs during the period of non-compliance.
• Eight consecutive months of inaccurate FOCUS reports means that FINRA’s own surveillance system was operating on false data for the entire duration. Regulators cannot respond to a gap they cannot see; Curvature’s filings made the gap invisible.
• The source of the error, a data pipeline quietly excluding short positions, is the kind of systemic technical failure that goes undetected precisely because it produces numbers that look plausible. No alarm triggered. No human reviewer flagged it. The compliance architecture at a 35-person registered broker-dealer simply did not catch it for eight months.
• Curvature’s own corrective action statement confirms that the controls now being mandated (documented formula changes, executive sign-off, weekly FINOP review meetings) were entirely absent before this investigation. This was a firm operating a legally mandated weekly calculation without any formal change-management or verification process.

Economic Inequality

The penalty structure in this case illustrates a recurring pattern in financial regulation: the fine is calibrated to what a firm can easily absorb, not to the scale of the risk it created for others.

• The $50,000 fine represents 0.17% of the total reserve shortfall. An individual caught shoplifting $50,000 worth of goods faces felony charges. A firm that runs a $29 million customer-protection gap for eight months faces a fine that, for a securities firm, rounds to a rounding error.
• Curvature waived its right to contest the findings, its right to a disciplinary hearing, and its right to appeal. The AWC explicitly states that this was done “voluntarily” with “no offer, threat, inducement, or promise of any kind.” In practice, waving all procedural rights and paying a small fine is the standard playbook for settling enforcement actions without admitting guilt, a playbook most ordinary defendants never get access to.
• No customer compensation was ordered or mentioned in the settlement. If any customer experienced harm during the eight months the reserve was underfunded, there is no mechanism in this settlement to make them whole. The $50,000 went to FINRA, not to any affected account holder.
• The firm’s legal representation (Sullivan & Worcester LLP, a major New York law firm at 1251 Avenue of the Americas) and the relatively modest fine outcome are consistent with a regulatory system where well-resourced financial firms can negotiate the terms of their own accountability in ways unavailable to individuals who break rules of similar or lesser financial significance.

The “Cost of a Violation” Metric

What Now?

This is what accountability looks like when the rules are enforced by a self-regulatory organization funded by the industry it polices. Here is what you can actually do.

The Parties of Record

• Curvature Securities LLC, CRD No. 169708, Chatham, New Jersey. Member of FINRA since 2014. The AWC is now part of its permanent disciplinary record and is publicly accessible via FINRA BrokerCheck.
• Todd Pigott, Chief Compliance Officer, signed the AWC on behalf of Curvature Securities on February 5, 2025.
• Michael Dyson and Meghan Roha of Sullivan & Worcester LLP, 1251 Avenue of the Americas, New York, NY 10020, served as counsel for the respondent.
• The settlement was accepted by FINRA’s Office of Disciplinary Affairs on February 6, 2025.

Watchlist: Regulatory Bodies With Jurisdiction

• FINRA (Financial Industry Regulatory Authority): The self-regulatory organization that brought this case. FINRA’s BrokerCheck database lists Curvature’s disciplinary record. If you are a Curvature client, you have a right to view it at finra.org/brokercheck.
• U.S. Securities and Exchange Commission (SEC): Exchange Act Sections 15(c) and 17(a), the statutory authorities cited in this AWC, fall under the SEC’s jurisdiction. FOCUS reports are filed with both FINRA and the SEC. The SEC has independent authority to pursue additional action based on the same conduct.
• SEC Office of Investor Education and Advocacy (OIEA): If you are a Curvature client and believe your account was affected by the reserve shortfall, you can file a complaint directly at investor.gov/additional-resources/news-alerts/alerts-bulletins/investor-bulletins/how-file-complaint.

Grassroots Resistance and Mutual Aid

• Check your broker on BrokerCheck before you trust them with a dollar. FINRA’s public database lists every disciplinary action, customer complaint, and regulatory event for every registered broker and firm. The information from this AWC will appear in Curvature’s record. Use it: finra.org/brokercheck.
• Push for penalty reform in FINRA’s self-regulatory model. Contact your congressional representatives and ask them to support legislation requiring FINRA fines to be proportional to the financial harm created, with a mandatory floor tied to the size of the violation. A $50,000 fine for a $29 million reserve gap is not a deterrent; it is a line item.
• Demand customer notification requirements. The current regulatory framework does not require a firm to notify its customers when it has been operating with an underfunded customer reserve. Advocate for rules mandating disclosure to affected account holders when reserve violations are confirmed. Contact the SEC’s public comment portal at sec.gov/regulatory-actions/rulemaking to submit comments on investor protection rules.
• Support organizations fighting for stronger financial consumer protections. The Consumer Federation of America (consumerfed.org) and Better Markets (bettermarkets.us) actively advocate for tougher Wall Street enforcement standards and publish research on the gap between financial misconduct and regulatory penalties.
• Share this record. The AWC is a public document. Its case number is 2023077005701. Send it to anyone who uses Curvature Securities or works with a broker-dealer and trusts that their money is protected. The most powerful tool against quiet accountability is loud transparency.
