How to spot deposit outflow to crypto exchanges in your transaction data

Community banks are the financial backbone of Main Street. They fund small businesses, agricultural operations, and families in communities where no one else shows up. That mission only works when deposits stay close to home — cycling back into the communities that generated them.

That cycle is quietly under pressure.

At KlariVis, we sit at the intersection of data and community banking every single day. And what we’re seeing in transaction data across our client base is something every community bank leader needs to understand: deposits are moving — steadily, incrementally — toward crypto exchanges. Not dramatically. Not all at once. But persistently enough that the lending implications are real.

This isn’t about taking a position on crypto. It’s about making sure community banks have the visibility to see what’s happening in their own data, and the tools to respond thoughtfully before a manageable trend becomes a material problem.

Recent transaction-level research analyzing nearly 226,000 Coinbase-related transactions across 92 community banks found that 9 in 10 had customers actively transacting with crypto exchanges, with $2.77 leaving for every $1 returned. Money market accounts showed the sharpest concentration: 96.3% of MMA-linked crypto transaction volume was outbound.

Today, this activity largely tracks crypto market cycles and speculative trading. But as Congress negotiates legislation that could allow crypto exchanges and stablecoin platforms to legally pay yield on holdings, what is currently speculative behavior could quickly become yield-driven deposit flight.

The behavioral infrastructure is already in place at most community banks: customer habits, account linkages, and transfer patterns are established. This playbook is about acting before the behavior shifts.

Signals to Look for in Your Data

Not all crypto activity looks the same. Some signals are loud and immediate. Others are quieter — patterns that only become visible when you’re paying attention. Here are the primary indicators worth monitoring:

• Recurring or growing ACH/wire transfers to known crypto exchanges or digital asset platforms (e.g., Coinbase, Kraken, Binance.US, Gemini, Robinhood Crypto, CryptoHub, Bitcoin Depot)
• Outflows originating from money market or high-balance DDA accounts — your most yield-sensitive customers
• Declining savings or MMA balances paired with crypto platform activity
• Reduced in-bank transaction frequency or card usage alongside crypto outflows

Beyond these, secondary signals — like customers asking about wire transfer limits, multiple small “test” transfers before larger movements, or new account openings followed quickly by large outbound transfers — can also indicate accelerating activity. The full list is in the playbook HERE.

How to Surface These Signals

Core system transaction data, ACH originator/receiver descriptions, and wire memo fields are your primary sources. Many banks can identify crypto exchange counterparties directly from transaction description strings (e.g., “Coinbase,” “Kraken”). Work with your data or operations team to build a recurring report or filter against known crypto exchange identifiers.

Where to Start

Once you’ve identified the activity, the response should be deliberate and relationship-first. A few places to begin:

• Prioritize by account type (MMA first), outflow size, and relationship value
• Assign calling responsibilities to the appropriate owner — retail, wealth, or digital banking
• Lead with a financial check-in conversation, not a product pitch. The goal is to understand customer goals, confirm liquidity needs are met, and position the bank as a partner alongside those activities

The conversation tone matters as much as the outreach itself. Avoid language that feels judgmental or alarmist. Customers exploring crypto aren’t doing anything wrong — and they’re more likely to stay if they feel understood, not redirected.

A Note on Guardrails

This kind of outreach requires care. Do not disparage crypto or discourage customers from their investment choices. Be transparent if your bank doesn’t currently offer yield-competitive alternatives. And if a customer signals they are moving amounts that appear disproportionate to their financial picture, treat it as a financial health conversation, not a product push.

Compliance and legal counsel should review any talk tracks before deployment given the evolving regulatory landscape around digital assets. The goal is retention through relationship strengthening — not through discouraging lawful financial activity.
