FCNR(B) vs US Treasury Bonds: What NRI & PIO in America Should Know in 2026

For NRI & PIO living in the United States, 2026 presents an unusually interesting comparison. US Treasury yields are sitting around [VERIFY: 4.5%], which makes them a credible benchmark for any India-linked fixed-income option. At the same time, RBI’s June 2026 relaxation have pushed USD FCNR(B) deposit interest rates up meaningfully — making this a genuine conversation, not a default choice in either direction. 

This article breaks down how FCNR(B) deposit compares for US-based NRIs, what you need to know about FATCA and DTAA, and how to think about the two as complementary parts of a cross-border portfolio.

You earn in dollars, your financial life is anchored in the US, and you likely have family ties, property aspirations, or a retirement plan linked to India. Your challenge isn’t just finding a good interest rate — it’s finding a good interest rate in a structure that works across two different regulatory and tax systems. FCNR(B) deposit is one of the few products that genuinely fits this picture: USD-denominated, held in India, but with none of the currency conversion or repatriation friction that rupee-based deposits carry.

RBI introduced a special forex swap facility in June 2026 for banks mobilising eligible FCNR(B) Deposits. Following a strong response and significant foreign currency inflows, RBI has now brought forward the mobilisation deadline for eligible FCNR(B) deposits to August 31, 2026.

For customers, the key distinction is that August 31 is the revised deadline for deposits eligible under RBI's special swap facility. It is not the closing date for the regular FCNR(B) Deposit product. 

FCNR(B) deposit interest is fully exempt from income tax in India for NRI/PIO. India does not deduct TDS on FCNR(B) deposit interest. However, US-based NRI/PIO need to factor in US tax rules: 

• The US taxes its citizens and green card holders on worldwide income, including foreign interest income 

• H-1B, L-1, and other visa holders on the Substantial Presence Test are also subject to US taxation on FCNR(B) interest 

The India-USA Double Taxation Avoidance Agreement (DTAA) allows you to claim a foreign tax credit in the US — but since India doesn’t tax FCNR(B) interest, there may be no Indian tax paid to offset against your US liability.

Note: FCNR(B) interest is likely reportable on your US tax return. The Indian tax exemption is an India-side benefit, not a US-side one. Consult a US-India crossborder tax advisor before making a decision based solely on the tax angle.

The Foreign Account Tax Compliance Act (FATCA) requires US persons to report foreign financial accounts above certain thresholds. An FCNR(B) deposit held at an Indian bank is a foreign financial account for this purpose. If your FCNR(B) deposit exceeds the applicable threshold, you will need to:

• Report it on your FBAR (FinCEN Form 114) 

• Potentially include it in your FATCA filing (Form 8938)

This is a standard compliance requirement — not a reason to avoid FCNR(B) deposit, but something to handle correctly. HDFC Bank is a FATCA-compliant institution and will collect your US person status at account opening.

Despite the US tax reporting requirement, FCNR(B) deposit offers things a US Treasury cannot: 

India connection: proceeds can be used directly for India-linked goals — property purchase, parental support, future return — without currency conversion friction 

No INR exposure: unlike NRE fixed deposits, FCNR(B) deposit keeps your principal in USD throughout, so your India corpus doesn’t shrink if the rupee weakens 

Full repatriability: principal and interest can come back to the US at any time after maturity 

Potentially higher rate: post-June 2026 relaxation, competitive with or above comparable US Treasury rates for 3-5 year tenors

The strongest case for FCNR(B) deposit isn’t that it replaces US Treasuries — it’s that it fills a different slot: a USD-denominated instrument with India-linked utility and competitive returns.

HDFC Bank supports non-face to face account opening for new to bank NRI/PIO customers. You will need: 

• A valid Passport copy 

• Address proof 

• Proof of NRI/PIO status

• PAN card 

• FATCA self-certification (collected at account opening)

• Documents to be certified by designated authorities prescribed by RBI 

Booking can be done via wire transfer from your US bank account.
