I Bonds vs TIPS: Which Inflation Hedge Pays More Now?

I bonds vs TIPS comes down to one gap: on October 30, 2026, Treasury set the new I bond fixed rate at 1.40%, the highest since November 2006, for a 5.51% composite rate. Five-year TIPS still offered about 2.25% real that same day. TIPS pay roughly 0.85 points more. I bonds win on tax deferral, a deflation floor and zero price risk.

Key takeaways

• New I bonds lock a 1.40% real rate, up from 0.90% in May.
• Five-year TIPS yielded about 2.25% real on October 30, 2026.
• Over five years, $10,000 earns roughly $457 more real return in TIPS.

What changed for I bonds on October 30, 2026?

Treasury reset Series I savings bond rates for purchases from November 1, 2026 through April 30, 2027. The fixed rate rose to 1.40% from 0.90%. The inflation component rose to 2.04% for six months, or 4.08% annualized. The composite is 5.51%, up from 4.26%.

The announcement came on Friday, October 30, as Tipswatch reported. The 1.40% fixed rate is the highest since November 2006. That matters more than the headline 5.51%.

Here is why. The fixed rate is locked for the bond’s full 30-year life. The inflation component resets every six months. The 5.51% you see today only applies to your first six months.

The backdrop explains the jump. The Fed held its target range at 3.75% to 4.00% on October 28, 2026, but two officials dissented in favor of a hike. The FOMC statement said plainly that “inflation remains elevated.” Real yields climbed all year, and Treasury’s fixed rate followed them up.

I bonds vs TIPS: which pays the higher real yield?

TIPS do. Five-year TIPS yielded about 2.25% above inflation on October 30, 2026, against the I bond’s 1.40% fixed rate. That is a gap of roughly 0.85 percentage points a year. The October 22 five-year TIPS auction cleared even higher, at a 2.367% real yield.

Both products add inflation on top of the real rate, using the same CPI-U index. So the real rate is the cleanest way to compare them. On that measure, TIPS have led all year.

The table below uses the latest figures available as of the dates shown. Treasury yield data for October 30 comes from the TIPSyield daily tracker, which republishes Treasury’s real yield curve.

Feature	I bonds (Nov 2026 issue)	5-year TIPS
Real (fixed) rate	1.40%, locked for 30 years	~2.25% (Oct 30, 2026); 2.367% at Oct 22 auction
Inflation adjustment	4.08% annualized for first 6 months	Principal indexed to CPI-U
Annual purchase limit	$10,000 per person (electronic)	No retail cap at auction
Minimum hold	12 months	None; sell any trading day
Early exit cost	Last 3 months of interest if cashed before 5 years	Market price, which can be below par
Federal tax	Deferred until redemption	Owed yearly on coupons and inflation accrual
State and local tax	Exempt	Exempt
Deflation protection	Accumulated value never falls	Original principal floor at maturity only

The skeptical read on the I bond reset: Treasury’s own formula still lags the market. Tipswatch’s long-running model, which applies a 0.65 ratio to the six-month average five-year TIPS yield, implied a “fair value” of 1.50%. Treasury paid 1.40%. Savers buying through TreasuryDirect accept a real rate well under what the bond market pays.

How much more does $10,000 earn in TIPS?

About $457 in real terms over five years, before tax. Inflation adds the same amount to both, so the real rate decides the gap. At 1.40%, $10,000 grows to about $10,720 in today’s dollars. At 2.25%, it grows to about $11,177.

The worked math

1. I bond real growth: $10,000 × 1.014⁵ = $10,720. Real gain: $720.
2. Five-year TIPS real growth: $10,000 × 1.0225⁵ = $11,177. Real gain: $1,177.
3. Gap: $1,177 − $720 = $457, or roughly $91 a year.
4. At the October 22 auction yield of 2.367%, the TIPS figure rises to $11,241, widening the gap to $521.

These figures use simple annual compounding for clarity. I bonds compound semiannually and TIPS pay semiannual coupons, so exact results differ by a few dollars.

What does cashing out early cost?

Redeem an I bond before five years and you lose the last three months of interest. On $10,000 at 5.51%, that is $10,000 × 5.51% ÷ 4 = $137.75. You also cannot touch the money for the first 12 months at all.

A TIPS holder can sell any day. The catch is price risk. If real yields rise after you buy, the bond’s market price falls, and selling early locks in that loss.

Does the tax treatment change the winner?

In a taxable account, it narrows the gap. TIPS owners owe federal tax every year on the inflation added to principal, even though they receive no cash for it. I bond owners defer all federal tax until they redeem. Inside an IRA or 401(k), the tax edge disappears and TIPS win cleanly.

The TIPS problem is called phantom income. Suppose inflation runs at the I bond’s current 4.08% annualized pace for a year. A $10,000 TIPS position accrues about $408 of principal. In the 24% bracket, that is roughly $98 of federal tax due in cash, with no cash received.

The I bond holder pays nothing until redemption. Both products are exempt from state and local income tax, so investors in high-tax states get no extra edge from either. Our earlier breakdown of TIPS vs Treasuries and the breakeven inflation rate covers how phantom income stacks against nominal bonds.

Are TIPS ETFs a cheaper way to own TIPS?

Not cheaper than buying TIPS directly, which costs nothing at a Treasury auction. But a low-cost fund gets close. The Schwab U.S. TIPS ETF (SCHP) charges 0.03%, according to ETF Database. The iShares TIPS Bond ETF (TIP) charges 0.18%, according to Seeking Alpha.

On $10,000, that is $3 a year in SCHP and $18 a year in TIP. Over five years the difference is $75 before compounding. ETF Database lists SCHP’s assets at about $15.7 billion, so liquidity is not a concern for retail-size trades.

One caution. An ETF never matures. A five-year TIPS bought at auction returns par plus inflation at maturity. A fund holds a rolling basket, so its price keeps moving with real yields forever. That is a different risk than holding a single bond to term.

Which inflation hedge fits which investor?

The answer depends on three things: the account type, how soon you might need the money, and how much you want to invest. Taxable savers with a five-year horizon and under $10,000 a year lean toward I bonds. Retirement accounts and larger sums lean toward TIPS.

Investor profile	Better fit	Why
Taxable account, backup emergency fund	I bonds	No price swings, deferred tax, cash out after 12 months
IRA or 401(k)	TIPS	Tax deferral already built in; higher real yield wins
Investing more than $10,000 a year	TIPS (or both)	I bond cap limits the position
Building a retirement income ladder	TIPS	Choose exact maturities across years
Worried about deflation	I bonds	Accumulated value cannot fall
Wants daily liquidity	TIPS ETF (SCHP 0.03%)	Trades any market day, though price moves

Cash that needs to stay fully liquid belongs elsewhere. We compared those options in T-bill ETFs vs money market funds and in USFR vs SGOV.

Is the 5.51% I bond rate better than T-bills?

For the first six months, yes on paper. Tipswatch cited a 4.42% one-year T-bill yield at the reset, below the 5.51% composite. But the comparison is misleading. The I bond rate is backward-looking, built from April to September 2026 inflation, and it resets in May.

A T-bill locks its yield to maturity. An I bond locks only its 1.40% real rate. If inflation cools, the composite falls. If it heats up, the composite rises. That is the point of an inflation hedge, but it means 5.51% is not a 12-month number.

Nominal rates set the context. TIPSyield’s data shows the 10-year Treasury at 4.94% on October 30, against a 2.60% 10-year TIPS real yield. That implies a 2.34% breakeven: the market expects inflation near that level for a decade, well below the I bond’s current 4.08% annualized inflation component.

What to watch next

Four dated events could shift the I bonds vs TIPS math before the next reset. Inflation prints move both products’ accrual. Auctions set fresh TIPS real yields. The May reset decides the next fixed rate.

• November 10, 2026: October CPI release from the Bureau of Labor Statistics. It is the first month feeding the May 2027 I bond inflation rate.
• November 19, 2026: Treasury reopens the 10-year TIPS (CUSIP 91282CRE3), per Tipswatch. Its secondary yield was 2.58% on October 30, down 33 basis points since October 5.
• December 10, 2026: November CPI release.
• December 22, 2026: Five-year TIPS reopening (CUSIP 91282CRR4).

The fixed rate you lock between now and April 30, 2027 stays 1.40% regardless. Treasury announces the next rate for bonds bought from May 1, 2027.

FAQ

What is the I bond rate for November 2026?

The composite rate is 5.51% for bonds bought from November 1, 2026 through April 30, 2027. It combines a 1.40% fixed rate with a 2.04% semiannual inflation rate.

Do TIPS pay more than I bonds right now?

Yes, on real yield. Five-year TIPS yielded about 2.25% real on October 30, 2026, versus the I bond’s 1.40% fixed rate.

How much can I invest in I bonds each year?

The limit is $10,000 per person per year in electronic I bonds, unchanged with this reset.

What is the penalty for cashing I bonds early?

You cannot redeem in the first 12 months. Between one and five years, you forfeit the last three months of interest. On $10,000 at 5.51%, that is about $137.75.

Why do TIPS create phantom income?

The inflation added to TIPS principal is taxable each year at the federal level, even though you receive it only at maturity or sale. Holding TIPS in an IRA avoids this.

Which TIPS ETF has the lowest fee?

Of the two compared here, SCHP is cheaper at 0.03% versus 0.18% for TIP. That is $3 versus $18 a year on $10,000.

The bottom line

On the measurable question, TIPS win. A 2.25% real yield beats 1.40% by about $91 a year on $10,000, and that gap is wider at auction. In a retirement account, there is no counterargument.

The I bond case rests on four specific conditions: a taxable account, a horizon of at least five years, a position under $10,000 a year, and a need for zero price risk. Meet all four and the 1.40% fixed rate, the best since 2006, is a reasonable trade for deferred tax and a deflation floor. Miss one and TIPS do the job better.
