Greenwich CT Mortgage Escrow Interest: What the New Federal Rule Changes

If you have a mortgage on a house in Greenwich, you almost certainly have an escrow account, and until this spring Connecticut law was clear about it: whoever holds that money owes you interest on it. Greenwich CT mortgage escrow interest is now an open question. A federal rule issued in May 2026 says national banks get to decide for themselves whether to pay it, and on August 11 Connecticut sued to stop that rule.

No one is going to win or lose a Greenwich house over an escrow account. But the balances sitting in these accounts here are unusually large, because the tax bills are, and it's worth understanding whose money is earning what while the courts sort this out.

Here's the plain version of where things stand.

Does Connecticut require lenders to pay interest on mortgage escrow accounts?

Yes. Connecticut General Statutes section 49-2a requires any bank, savings institution, insurance company, or mortgage servicer holding a Connecticut homeowner's escrow funds for taxes and insurance to pay interest on those funds.

A few details in that statute matter for how it actually feels as a homeowner. It applies to owner-occupied residential property of no more than four living units, plus housing cooperatives occupied solely by their shareholders. The rate can't be less than the state's deposit index, set annually under section 36a-26 and rounded to the nearest tenth of a percentage point.

For 2026, the Connecticut Department of Banking set the deposit index at 0.49%, announced December 9, 2025. Rounded as the statute directs, that puts the escrow floor at 0.5% for this year.

The interest doesn't arrive as a check. Section 49-2a says it's credited on December 31 each year and applied toward the next year's taxes or insurance. The exception: if you pay off the mortgage before December 31, the interest through that date is paid to you.

There's also a carve-out that suddenly matters a great deal. Section 49-2c excuses the interest requirement where paying it would violate any federal law or regulation. That clause is the exact pressure point in the current fight.

What did the OCC actually change in May 2026?

On May 15, 2026, the Office of the Comptroller of the Currency issued two final rules. One codifies national banks' authority to set the terms of mortgage escrow accounts themselves, including whether to pay interest at all. The other is a formal preemption determination.

Per OCC Bulletin 2026-21, that determination concludes the National Bank Act preempts New York's interest-on-escrow statute, and that 13 other states and territories have laws with substantively equivalent terms that are preempted too. Fourteen in total. Connecticut's law is one of them.

The bulletin is addressed to national banks, federal savings associations, and federal branches and agencies of foreign banks. It notes explicitly that the determination applies to all community banks, which the OCC defines as institutions with up to $30 billion in assets. So this isn't only about the largest lenders.

Why did Connecticut sue?

On August 11, 2026, Attorney General William Tong joined nine other state attorneys general in filing Oregon et al. v. Office of the Comptroller of the Currency in the U.S. District Court for the District of Oregon. California, Maine, Maryland, Massachusetts, Minnesota, New York, Oregon, Rhode Island, and Vermont are the others.

The states argue the OCC exceeded the limits Congress placed on national bank preemption under Dodd-Frank and violated the Administrative Procedure Act. They're asking the court to declare both rules unlawful and vacate them, according to the National Law Review's August 13, 2026 summary of the filing.

Tong's office put the consumer framing bluntly: "This new rule will put banks first, families last, and strip states of yet another tool put in place to help consumers."

The state also raised a competition point that's easy to miss. If national banks are exempt from Connecticut's interest-on-escrow law but Connecticut's own state-chartered banks still have to follow it, the smaller local institutions are the ones carrying the cost.

How much escrow interest is actually at stake on a Greenwich home?

Tens of dollars a year on a typical house, not thousands. The reason it's worth a look anyway is that Greenwich escrow balances are large in absolute terms, because the underlying tax bills are.

Run the arithmetic with public numbers and you can see the shape of it. Connecticut assesses property at 70% of market value. Greenwich's fiscal year 2026-27 mill rate is 10.12, which Board of Estimate and Taxation Chair David Weisbrod described as the lowest in Connecticut when the budget was set. The Greenwich Association of REALTORS reported a median single-family sale price of $3,602,000 for July 2026.

A house at that median assesses at roughly $2.52 million, which works out to about $25,500 a year in town property taxes. Spread across twelve escrow payments, that's roughly $2,125 a month going in for taxes alone, before homeowners insurance, which isn't cheap on this stretch of the Sound either.

Federal escrow rules under Regulation X (12 CFR 1024.17) let a servicer collect one-twelfth of estimated annual disbursements each month and hold a cushion of up to one-sixth of the annual total, roughly two months' worth. Greenwich bills real estate tax in two installments, due July 1 and the following January 1, so the balance climbs and then drops twice a year rather than draining evenly.

If your account averages $12,000 across the year, 0.5% is about $60. If it averages $20,000, it's about $100. Those are illustrations built on the inputs above, not a reading of anyone's actual statement, and your own balance depends on your insurance premium, your closing date, and how your servicer set the cushion.

Modest money. It's still your money, and under Connecticut law it's been credited toward your next tax bill rather than kept by the bank.

Does it matter whether your lender is a national bank or a Connecticut bank?

Under the OCC rules as written, yes. That's the practical distinction for a Greenwich buyer shopping lenders right now:

• National bank or federal savings association: the OCC's determination says it can decide whether to pay escrow interest, without regard to section 49-2a. Subject to how the Oregon case comes out.
• Connecticut state-chartered bank or credit union: not covered by the OCC's preemption determination, and still subject to Connecticut's interest-on-escrow requirement. This is the disadvantage Tong's office flagged.
• Non-bank mortgage servicer: section 49-2a names mortgage servicers directly, while the OCC's determination is addressed to institutions the OCC regulates.
• Whoever you close with, your loan can be sold, and the servicer holding your escrow can change more than once over thirty years.

This is a moving target and none of it is legal advice. If it matters to you, ask the lender in writing and keep the answer.

What should Greenwich homeowners and buyers do right now?

• Look at your December 31 escrow statement this year and see whether an interest credit appears. That's the single clearest signal of how your servicer is treating this.
• Ask your lender directly, in writing, whether they pay Connecticut escrow interest under section 49-2a and whether that's changing. A one-line email now saves an argument in January.
• If you're comparing loan offers, put escrow treatment on the list, then keep it in proportion. Rate, points, and fees will almost always outweigh a $60 credit.
• Reconcile your escrow after the reval. Greenwich completed a town-wide revaluation and adopted a new budget in the same cycle, and Weisbrod's July 2 letter to residents laid out why bills moved differently for different houses. If your assessment jumped, your escrow payment should have been re-analyzed to match.
• Watch the case rather than the headlines. Nothing about your account changes because a lawsuit was filed.

Key takeaways

• Connecticut General Statutes section 49-2a requires lenders and servicers holding escrow funds on owner-occupied Connecticut homes to pay interest, credited every December 31 toward the following year's tax or insurance bill.
• The Connecticut Department of Banking set the 2026 deposit index at 0.49% on December 9, 2025, which puts this year's escrow interest floor at 0.5% after statutory rounding.
• OCC Bulletin 2026-21, issued May 15, 2026, concluded that federal law preempts interest-on-escrow laws in 14 states and territories, Connecticut among them, for national banks and federal savings associations.
• Attorney General William Tong and nine other attorneys general sued the OCC on August 11, 2026 in the District of Oregon, arguing the agency exceeded its Dodd-Frank preemption authority.
• On a Greenwich house at the July 2026 median sale price of $3,602,000, town property taxes run roughly $25,500 a year at the 10.12 mill rate, so escrow balances here are large even though the interest at stake is modest.

Frequently Asked Questions

What is a mortgage escrow account?

It's an account your lender or servicer maintains to pay your property taxes and homeowners insurance for you. You pay into it monthly as part of your mortgage payment, and the servicer disburses the money when the bills come due. In Greenwich, real estate tax bills come due July 1 and January 1.

Does my Greenwich lender have to pay me interest on escrow in 2026?

It depends on who holds your loan. Connecticut's section 49-2a says yes, at a 2026 floor of 0.5%. The OCC's May 15, 2026 preemption determination says national banks and federal savings associations can decide for themselves. Connecticut and nine other states sued on August 11, 2026 to overturn that determination, and the case is pending.

How is Connecticut escrow interest paid to me?

Under section 49-2a it's credited on December 31 each year and applied toward the taxes or insurance owed in the following year, so you generally see it as a credit rather than a payment. If you pay off the mortgage before December 31, the interest accrued through that date is paid to you directly.

How much money sits in escrow on a typical Greenwich home?

More than most places, because the tax bill is larger. At the July 2026 median single-family sale price of $3,602,000 and the 10.12 mill rate, town taxes alone are around $25,500 a year, which is roughly $2,125 a month flowing into escrow before insurance. Regulation X lets servicers hold a cushion of up to two months of disbursements on top of that.

Can I waive escrow and pay my Greenwich taxes myself?

Sometimes. Escrow waivers are a lender decision and typically depend on your loan type and your down payment, and some lenders charge for the privilege. If you do go without escrow, you're responsible for hitting the July 1 and January 1 deadlines yourself, and the Town of Greenwich charges 1.5% per month, 18% a year, on late payments.

Thinking about buying or selling in Greenwich?

Escrow interest is a small line item, but it's the kind of detail that tells you whether someone is paying attention. We track the town budget, the reval, and the lending rules the same way we track inventory in Old Greenwich, Riverside, Cos Cob, and the backcountry, because all of it ends up in the number you write on a check.
