In brief

I-bonds are U.S. Treasury savings bonds whose interest combines a fixed component with an inflation-linked component.

The common picture

TreasuryDirect.govThe store. The UI is a 2004 ghost.

12-month lockCannot cash at all in year one.

5-year / 3-month penaltyCash out in years 1–5, lose last 3 months of interest.

2022 9.62% ghostThe number people still say in 2026. Not the current rate.

Electronic I-bond purchase cap: $10,000 a calendar yearThis is the standard individual purchase limit through TreasuryDirect; gifts and separate entities have their own rules.

People discuss holding periods, access to the money, TreasuryDirect administration and comparisons with other places to keep savings.

Good to know. Treating last year’s 9.62% as a current product. Putting the only emergency month here. Losing the TreasuryDirect password.

What people say

The job: A government savings bond with an inflation component.
Why it was loud: 2022’s rate. Why it cooled: the rate fell and Treasuries / HYSA got simpler.
Bogleheads still hold some as a slice of “safe.” They do not pretend it is a HYSA.
Emergency fund debate: lockup vs inflation protection. Many keep I-bonds as a *slice*, not the whole starter fund.
The website is the other half of the lore — passwords, entities, gifts.
Paper vs electronic leftover talk. New buyers are electronic.
State-tax treatment is a perk people mention. They verify for themselves.
Not a 2026 flex. The flex year ended.
You cannot buy these in a normal brokerage the same way. TreasuryDirect is the ritual.
Not advice. Rates change every 6 months in the product’s design.
$STUD is not an I-bond.

How people do it

They only buy money they will not need this year.
They write down TreasuryDirect recovery info like it is a will.
They keep the real starter fund in a HYSA.
They check the current composite rate — not a 2022 screenshot.
They calendar the 12-month and 5-year marks.
Gifting / tax-time purchases have their own folklore. They read the current page.
If the UI defeats them: they stay in HYSA. Fine.

Amounts people use

Electronic purchase cap: $10,000 per calendar year for an individual owner under the standard TreasuryDirect limit. Separate gift and entity rules remain distinct.
Emergency slice: 0–3 months of expenses in cautious diaries, rest in HYSA.
2022 rate people still quote: 9.62%. History, not an offer.
2026 feel: closer to “why bother vs HYSA” in a lot of comments.
Penalty: last 3 months of interest if cashed before 5 years.

How people keep it

Password manager + a paper backup someone they trust can find.
A note in the emergency-fund doc: “$X is locked until DATE.”
They do not check the rate weekly after purchase. They already bought.
They buy earlier in the month if they care about the dating folklore — optional nerdiness.
They stop buying when the rate is not worth the UI.

How it may feel

2022 buyers: genius, then trapped, then fine.
2026 buyers: underwhelmed.
Lost TreasuryDirect login: a special panic.
Cashing at month 13: relief plus a small penalty shrug if before year 5.
Explaining I-bonds at dinner: someone’s uncle mentions 9.62 again.
The good version: a boring slice they forgot.

How long

Minimum 1 year. Productive hold often 5+ to skip the penalty.
They can hold 30 years in the product design.
A 2022 pile may just sit until they need a house or a year-5 birthday.
Not a trading vehicle.

The longer notes

HYSA is the liquid cash job.
Full emergency fund can include a slice, not the first $1,000.
T-bills are the other Treasury nerd parking spot.
Inflation protection is the pitch. Liquidity is the cost.
Not advice. Rates reset.

Good to know

Do not lock the only emergency month.
9.62% is a history fact.
Write down the login.
This is not a brokerage ticker.
UI rage is a valid reason to skip.

Earlier wording (updated)

Annual purchase limit talk A cap exists. They look up this year.

Purchase cap: look up the current year electronic limit. This page will stale.
