Your money doesn't have to sit in a bank to be exposed to risks. From Starbucks gift cards to digital wallets and nonbank lenders, a growing network of unregulated financial institutions is holding billions of dollars in consumer funds, generally with minimal oversight

Key insights:

      • Convenience has outpaced consumer understanding — Many users treat apps, prepaid accounts, and rewards programs as simple payment tools, remaining unaware they are entrusting their money to entities with few safeguards.

      • Risk is no longer confined to traditional banks — Some of the most significant financial activities now occur within platforms and brands that do not resemble banks at all.

      • Opacity enables systemic vulnerability — The less transparent an institution’s obligations, leverage, and oversight, the easier it is for financial fragility, misconduct, and systemic risk to grow unchecked.


When you think of where money is held, you generally think of a bank. However, as we look at the financial landscape today, money is being held at a wide range of institutions that often have varying levels of safety and oversight. Entities from Starbucks to Visa to Coinbase hold money for individuals, effectively serving as a bank, but often without the regulatory framework that comes with it.

Behind the scenes, it can seem like Starbucks is quietly operating like a bank. In its daily operation, it collects prepaid funds that resemble deposits, holds them as liabilities, and uses them internally — all without offering interest, cash withdrawals, or FDIC insurance. Starbucks’ rewards program holds $1.8 billion in customer cash, and if it were a bank, that would make it bigger, by total deposits managed, than 85% of chartered banks, making the coffee chain one of the largest financial institutions in the country.

This dynamic extends well beyond coffee shops. “Popular digital payment apps are increasingly used as substitutes for a traditional bank or credit union account but lack the same protections to ensure that funds are safe,” warns the Consumer Financial Protection Bureau (CFPB). If a nonbank payment app’s business fails, your money is likely lost or tied up in a long bankruptcy process.

Shadow banking

Think of a Starbucks gift card as a financial instrument. Technically it is one, but no one seriously worries about it being weaponized for any large-scale financial crimes. Most people’s concerns about a gift card is either losing it. The real concern lies not in lost gift cards, however, but in the broader trend: Nonbank institutions managing vast sums without commensurate oversight — and scale matters. A lost gift card is a personal inconvenience; but an unregulated institution managing billions of consumer dollars in leveraged capital is a systemic one.

Shadow banking encompasses credit and lending activities by institutions that are not traditional banks, and crucially, they do not have access to central bank funding or public sector credit guarantees. And because they are not subject to the same prudential regulations as depository banks, they do not need to hold as high financial reserves relative to their market exposure, allowing for very high levels of leverage which in turn can magnify profits during boom periods and compound losses during downturns.

The shadow banking ecosystem is diverse, and each segment of it presents distinct risks:

    • Hedge funds and private equity firms — Firms like Blackstone, KKR, and Apollo manage vast capital pools using leveraged strategies under limited oversight. Their size and borrowing levels may mean that market reversals can trigger rapid deleveraging, spilling risk into broader markets.
    • Family offices — A private company or advisory firm that manages the wealth of high-net-worth families, these can operate with even less transparency and often outside direct regulatory scrutiny, enabling them to engage in extreme leveraging and posing risks of sudden collapse.
    • Nonbank mortgage lenders and FinTechs — This group faces lower capital requirements than traditional banks, leaving thinner buffers to absorb losses during downturns, which can be especially concerning considering this sector’s rapid growth.
    • Crypto exchanges — Like much of the cryptocurrency ecosystem, these exchanges operate in jurisdictional gray zones, complicating enforcement and enabling illicit financial flows.
    • Money market funds — While these are generally perceived as safe, they can suffer runs if confidence in underlying assets erodes, which can force fire sales that destabilize related markets.
    • Special Purpose Vehicles (SPVs) and Structured Investment Vehicles (SIVs) — These investment instruments allow large institutions to move risk off their balance sheets, rendering such activity invisible to regulators.

Shadow banking may be the single greatest challenge facing financial regulation. These non-traditional institutions act like banks, but without the safeguards that make banks accountable. And where accountability is absent, opportunity often fills the void.

The same opacity that makes shadow banking difficult to regulate also makes it attractive to those with less legitimate intentions. Without mandatory reporting requirements, standardized oversight, or the threat of deposit insurance revocation, these institutions can become conduits for money laundering, fraud, terrorist financing, and sanctions evasion in ways that traditional banks simply cannot. The question is no longer whether these vulnerabilities exist, but how they continue to be exploited.

The challenge of regulation

The global financial system has always evolved faster than the rules designed to govern it. What began as a coffee loyalty program and a few alternative lending platforms has quietly morphed into a parallel financial universe, one that moves trillions of dollars with a fraction of the transparency that traditional banking requires. That gap between innovation and oversight is not just a regulatory inconvenience, it’s an open door for illicit actors.

Closing that door will require more than periodic enforcement actions or piecemeal legislation. It will require regulators, lawmakers, and institutions to reckon honestly with how broadly the definition of a financial institution has expanded, and who bears the risk when things go wrong. Because historically, it has not been the institutions themselves; rather it has been the customers, the investors, and ultimately the public.

The first step, of course, is awareness. Recognizing that your money does not need to be in a bank to be at risk and that the custodians of that money need not be offshore shell companies to operate in shadows, can transform how we think about financial safety.

The line between a convenient app and an unaccountable financial intermediary is thinner than most realize. And in the world of financial crime, thin lines have a way of vanishing entirely.
