BMO Alto CD Review (2026), The $200B Big Bank's Online-Only Play
Quick take: BMO Alto is the online-only deposit brand of BMO Bank N.A. (the US subsidiary of Bank of Montreal, NYSE: BMO). $0 minimum, no monthly fees, and a clean online CD product, but the rate has fallen well off the top of the market: 2.50% APY on the 12-month CD as of September 25, 2026 (Alto Online Savings paid 3.00%).
| Product | APY | Source, as of |
|---|---|---|
| Alto Online CD, 12-month | 2.50% | alto.bmo.com, 9/25/2026 |
| Alto Online Savings | 3.00% | alto.bmo.com, 9/25/2026 |
BMO Alto publishes its 12-month CD APY on its home page; it offers 6 fixed CD terms (6 to 60 months), $0 minimum. Alto’s 12-month CD is no longer a top-of-market rate. For comparison, A-rated 5-year MYGAs topped out around 5.80% to 6.00% (AnnuityRateWatch, September 24, 2026). Rates change weekly. Other rate figures further down this page are as of June 27, 2026.
CD vs MYGA, after tax
What $100,000 earns in 5 years: CD vs MYGA, after tax
Rates used: CD 4.50%, the top nationally available 5-year CD (DepositAccounts, September 24, 2026); change it to the rate you are offered. MYGA 5.95%, the best A-rated rate we track as of October 13, 2026: Delaware Life Pinnacle Plus 5-year (AM Best A-, negative outlook, 7/31/2026), $100,000 and up, effective October 6, 2026 (Delaware Life rate sheet).
| CD, interest taxed every year | $118,826 |
|---|---|
| MYGA, tax-deferred, before tax | $133,507 |
| MYGA after paying tax on all the interest at withdrawal | $126,136 |
| Tax deferral alone adds about | $674 |
| MYGA ahead of the CD, after tax | $7,310 |
Assumes 22% federal and 0% state income tax, no withdrawals, rates held for the whole term. MYGA interest is taxed as ordinary income when you withdraw it, not as capital gains. Gains taken before age 59 1/2 can owe a 10% IRS penalty, and cashing out early can cost a surrender charge. In an IRA both grow tax-deferred, so the edge there is the rate alone. Bank and credit union deposits are FDIC or NCUA insured up to the limits; a MYGA is backed by the issuing insurer's claims-paying ability and your state's guaranty association up to its limits, not the FDIC.

Who BMO Alto is
BMO Alto is the online-only deposit brand of BMO Bank N.A., the US subsidiary of Bank of Montreal (NYSE: BMO, TSX: BMO). BMO Bank N.A. holds ~$280 billion in US assets following the 2023 acquisition of Bank of the West from BNP Paribas. The parent (Bank of Montreal) holds ~$1.4 trillion in total assets globally and is one of the largest banks in North America.
BMO Alto launched in 2023 as a national online deposit-gathering brand, effectively BMO's answer to Marcus, Synchrony, and Ally. It is NOT a separate bank; deposits are held by BMO Bank N.A. (FDIC cert #16571).

Why BMO Alto rates lead the pack
BMO is gathering deposits aggressively to fund the integrated balance sheet post-Bank-of-the-West acquisition. That funding pressure means BMO Alto consistently sits at or near the top of online-bank CD leaderboards across the curve. That is no longer true: on September 25, 2026 the 12-month CD paid 2.50% APY, well below the top 1-year CDs.
The $0 minimum is a real differentiator vs $1,000-$1,500 minimums at most online banks. You can build a small starter ladder with $5,000 split across five rungs without rounding issues.
What we like about BMO Alto CDs
- Rates consistently in top quartile across the full curve
- $0 minimum, rare combination with big-bank backing
- BMO Bank N.A. is one of the largest US banks (~$280B assets)
- FDIC-insured at the BMO Bank N.A. level, same protection as a BMO retail branch deposit
- No monthly fees, no minimum balance, no maintenance charges
- Clean, modern web/mobile experience built fresh in 2023
What we don't
- Brand is new (launched 2023), less customer-service track record than Marcus or Ally
- Cannot link to BMO retail checking under the same login, Alto is a standalone deposit-only brand
- 5-year rate (4.30%) still trails MYGAs by 100+ bps
- 365-day EWP on 4-5 year terms is harsher than Ally (150 days on 5-yr)

When a MYGA beats this BMO Alto CD
Even BMO Alto's competitive 5-year at 4.30% trails MYGAs materially. Compare $250,000 over 5 years:
- BMO Alto 5-yr CD at 4.30%: $250,000 grows to $308,737 (taxable annually)
- A-rated 5-yr MYGA at 5.80% (low end of the A-rated range on September 24, 2026, AnnuityRateWatch): $250,000 grows to $331,412 (tax-deferred)
- Pre-tax delta: $22,675 in favor of the MYGA
BMO Alto's edge is on the 1-2 year part of the curve; for the 5-year, the MYGA is a more efficient instrument unless you specifically need FDIC at the $250K cap or expect to break the contract early. Note: in California, the state guaranty fund covers MYGAs up to $250,000 per carrier, similar in dollar terms to FDIC's per-bank cap.

My take
BMO Alto is one of the best 1-year CD products in the market right now, top-quartile yield, $0 minimum, and a $280B big-bank balance sheet behind it. Use it for shorter tenors; for 5-year money, MYGAs still beat the math.

Disclosure
This review reflects publicly available bank rate sheets and approximate APYs as of the date stated above. CD rates change frequently, sometimes weekly, and the rates above may be stale by the time you read this. Always confirm current rates and terms against the bank's current rate sheet and disclosure documents before opening an account. FDIC insurance covers $250,000 per depositor, per insured bank, per ownership category; deposits above that amount at a single bank are not insured. This article is general information for educational purposes; it is not personalized financial advice, a solicitation, or an offer of any specific product. Hans Goldstein is an independent licensed insurance producer (NPN 20602398) and is not a bank, deposit broker, or registered investment adviser. CDs are bank deposit products and are not sold by insurance producers; references to CDs are for comparison context only. MYGAs (multi-year guaranteed annuities) are insurance contracts, subject to surrender charges and state guaranty fund coverage rather than FDIC. Early withdrawal of a CD before the maturity date typically results in a penalty that may exceed interest earned. Always read the actual deposit account agreement and consult a licensed advisor before making material financial decisions.
