FCNR vs HYSA vs US Treasury: Best Savings Options for NRIs?

If you're sitting on US dollars and deciding where to park them, the honest answer is: it depends on what you're optimizing for.

FCNR deposits usually post the highest headline rate right now, a high-yield savings account (HYSA) wins on flexibility and simplicity, and US Treasury bills win on safety plus a state tax break that neither of the other two offers. I'd never tell a client to chase the top number on a rate table without checking what the IRS and your home state do to it first.

Here's how the three actually compare once you run the numbers the way I do for clients.

What is FCNR?

An FCNR (Foreign Currency Non-Resident) deposit is a fixed-term deposit you open with an Indian bank, but it's held in a foreign currency, usually US dollars, not rupees. Only NRIs and OCI cardholders can open one, and you pick a tenure between one and five years. The rate is fixed for that tenure and set by the bank, subject to an RBI ceiling, and opening an FCNR account requires NRI or OCI status plus a transfer from abroad. In India, the interest is exempt from tax under Section 10(15) of the Income Tax Act for as long as you hold NRI or RNOR status. That exemption is real, and it's also the part everyone stops reading at, which is where the trouble starts if you're a US taxpayer.

What is a HYSA?

A high-yield savings account is an ordinary US savings account, usually at an online bank, that pays a meaningfully higher rate than the roughly 0.6% national average you'd get at a large branch bank. You open it the same way you'd open any US bank account: no NRI status required, no foreign paperwork, no minimum tenure. Money moves in and out whenever you want, and the rate floats with whatever the Federal Reserve is doing that quarter. It's the least exotic of the three options here, and that's the point.

FCNR vs HYSA vs US Treasury: Detailed comparison

Please note: Data accurate as of August 2026. FCNR and HYSA rates change bank to bank and week to week; verify the current rate before opening anything. Treasury yields come from the Treasury's daily par yield curve, published every trading day.

For most NRIs who are also US taxpayers, the FCNR row that decides this isn't the yield column, it's the one two rows down.

A 7% FCNR rate and a 4.2% HYSA rate land closer together than they look once you've paid US tax on both, because the FCNR side gets no credit for the tax India didn't charge in the first place. The 6.5% to 7.1% rates you'll see quoted at smaller banks are real, driven by the RBI's swap-window incentive, but a rate that good is still only as good as what's left after your US bracket takes its share.

FCNR vs HYSA vs US Treasury: which one should you choose?

There's no single winner here, because the three products are answering different questions. FCNR is a bet on a specific bank's rate for a fixed number of years. HYSA is for money you might need. Treasury bills are for money you want completely safe and don't want locked to one bank.

Choose FCNR if:

• You've confirmed your all-in FCNR rate genuinely beats a HYSA and a Treasury bill after you've accounted for US tax, not before
• You're not a US taxpayer, or you're in a low enough bracket that the missing foreign tax credit barely matters
• You don't mind the money being locked for the tenure, and you're comfortable with DICGC's roughly $6,000 protection ceiling on a deposit that's often much larger

Choose HYSA if:

• You want the money accessible for an emergency fund, a near-term move, or a down payment you can't predict the timing of
• You'd rather not deal with the FBAR filing or Form 8938 paperwork that a foreign account like FCNR triggers
• You want FDIC protection on the full balance without doing currency math
• Your bracket is high enough that you want to shop the after-tax rate, not the sticker rate

Choose US Treasury if:

• You live in a state with meaningful income tax, California and New York both tax at rates that eat straight into a bank rate but not into Treasury interest
• You want zero counterparty risk and don't want to think about deposit insurance ceilings at all
• You're comfortable buying bills yourself through TreasuryDirect or a brokerage, and laddering maturities instead of locking one multi-year rate

Can you use more than one?

Holding two of these at once is usually the right call rather than a failure to decide, and here's how I'd split them. A HYSA holds the true emergency fund, three to six months of expenses, because it has to be available the day you need it.

Treasury bills, laddered across a few maturities, hold the money you know you won't touch for a year or two but still want liquid enough to sell if a better use for it shows up.

FCNR earns a place only for the portion you're genuinely willing to lock away for the full tenure, and only after the after-tax math has actually been run for your bracket and your state.

The bottom line

FCNR, a HYSA, and a Treasury bill are each right for a different job, not competing for the same one.

If you're a US taxpayer holding cash you might need, a HYSA usually keeps more of its rate after tax and skips the FBAR paperwork entirely. If you want the safest possible dollar and a state tax break, ladder Treasury bills.

FCNR earns its place only when you've actually run the after-tax number for your bracket and still come out ahead, and once you run it, I'd expect that group to be smaller than the rate table alone would suggest.

Whichever way you land, check the math against your own state and bracket before you lock a rate anywhere.
