LifeX TIPS ETFs: Monthly Inflation-Adjusted Income
Sometimes it seems like everyone just wants risk these days. Crypto. Sports gambling. Options trading, ETFs that magically yield 10% or more. However, if you’re in the opposite camp and you want the absolute least amount of risk, you’d want to retire off an investment that has a return that is fully-guaranteed, pays out a monthly income like clockwork, is even guaranteed to grow with inflation.
If that interests you, check out 3 Ways to Build an Inflation-Adjusted Pension by Allan Roth – which first reminds you that Social Security is exactly this! – but also introduces a new series of LifeX Inflation-Protected Longevity Income ETFs.
At current rates as of 12/11/25, the LifeX 2055 Inflation-Protected Longevity Income ETF (LIAM) contains a managed portfolio of United States Treasury Inflation Indexed Bonds (TIPS) that can provide you with a 4.26% guaranteed real withdrawal rate for 30 years. That means a $1,000,000 portfolio would distribute roughly $42,600 in annual income for 30 years (through the year 2055), but importantly would increase with CPI inflation each year. At 3% average inflation, your 30th year’s income would have grown to over $100,000 a year.
After those 30 years, you will be left with nothing. Your initial principal will be gone. Therefore, your income taken each year is partially a return of principal.
The expense ratio is 0.25%, which isn’t Vanguard-level but not horrible. I like that it does all of the work for you in a tidy ETF package, as building a TIPS ladder yourself can be a bit tricky (and do you want to keep doing it at age 80, 90?). Of course, I also worry about what happens if you bought a 30-year ladder at 65 and happen to live past 95. It could happen, and remember, this product is meant for the risk-averse folks that like to cover all the bases.
In general, I feel a TIPS ladder or equivalent that adjusts with inflation would work well in combination with a traditional annuity like an SPIA or a deferred longevity annuity that starts at a later age, which doesn’t adjust with inflation but does provide an higher initial fixed income that can last as long as you live. This is what I have set up for my parents – Social Security that rises with inflation, plus a joint income annuity that pays out as long as one is living.
inKind Dining App: New $25 off $25 Promo
Added new $25 off $25 link (may be targeted). inKind is a startup that provides restaurants financing in exchange for “food and beverage credit”. Retail customers can use inKind to pay their food bill at participating restaurants through the app and get 20% back in “inKind Cash” credit on their bills. They say over 4,000 restaurants are in their network, mostly nicer local spots, but some chains like California Pizza Kitchen are also included (which is a favorite for our family).
The good thing is that you don’t have to let the server know ahead of time, or do anything awkward like using a coupon. You just get the check and then use the inKind app to pay. All the restaurants use the same backend Toast software, so you just need a number from the top of the paper bill. Within the inKind app, you can link your existing rewards credit card and also earn those rewards on your net cost (will still code as dining). inKind works primarily for dine-in, but some restaurants do specifically allow take-out. You are supposed to order the takeout from within the inKind app, but as long as you get the bill with the code, you should be able to pay using the app.
Current promos:
- New customers should first open via a $25 off $50+ referral link (that’s mine, thanks if you use it!). Expires 30 days after claiming. “Friend of Jonathan”.
- Existing customers can visit this separate $25 off $25+ link for another order. May be targeted. “Your End of Year Reward”. Expires 12/14/2025.
- Existing customers can visit this separate $25 off $50+ link for another order. May be targeted. “Mystery Reward”. Expires 45 days after claiming.
- Existing customers can visit this separate $25 off $50+ link for another order. May be targeted. “We Miss You”. Expires 30 days after claiming. Hat tip to DoC.
- $10 off $30. Expires 11/25.
- Existing customers can visit this separate $25 off $75+ link for another order. Expires 30 days after claiming. Marked as “Anniversary Gift”.
- Existing customers can visit this separate $15 off $15+ link for another order. May be targeted. Added October 2025 and marked as “Thanks for your feedback”.
- Existing customers can visit this separate $25 off $50+ link for another order. May be targeted. Added October 2025 and marked as “Thanks for your feedback”.
If you have a big bill, know that you can “split the check” within the app, so that two separate people can use a $25 off $50 discount in their respective inKind apps.
You should see your multiple offers in the app:
California Pizza Kitchen is part of the inKind network, and they are a reliable way to use these offers. They usually have some sort of promo going, like right now they have $10 Pizzas on Monday and Tuesday that you can stack.
Now, I can’t guarantee this will work for you, but this may work with CPK take-out and not just dine-in. (Be sure order directly from CPK.com or over the phone, not another app like Doordash or Grubhub.) The place we go to just has a separate take-out counter and the default check that comes from them should work with inKind. If not, tell them you want to pay with inKind and they should be able to generate the right check with the number on top. Make sure you meet the minimum purchase amount.
SoFi Offers: SoFi Plus Changes, New 5% Grocery Card, $325/4.20% APY Checking Bonus, $300-$1000 Loan Bonuses
Update December 2025: SoFi announced some changes to their available features and what is only available with their SoFi Plus “Premium” membership program. I feel that they are trying to build something like “Robinhood Gold”, but hopefully better promos are coming because I don’t feel the perks are worth the cost right now. First, there are now three different ways to earn their higher APY tier (any single ONE of these is enough):
- Eligible Direct Deposit of any amount (even $1). Many people can split their paycheck multiple ways.
- $5,000+ in combined balances across SoFi Checking and Savings accounts
- SoFi Plus members that pay $10/month fee.
You can see this on their rate sheet (as of 11/12/25):
Second, SoFi Plus is now paid-only at $10/month. You no longer get it for free with a direct deposit, although they are extending complimentary access to all SoFi Plus benefits through March 30, 2026 with eligible deposits. You can see a list of SoFi Plus benefits here.
For the most part, the SoFi Plus benefits are the same as before. A notable new addition is the SoFi Smart Card which is a charge card linked to your SoFI Bank accounts that offers unlimited 5% cash back at grocery stores.
Otherwise, I would say the most valuable SoFi Plus perks that existing Direct Deposit folks lost with this change are:
- 10% rewards boost on the SoFi Unlimited 2% Credit Card, which turns the 2% cash back into 2.2% cash back.
- 2% match on recurring IRA contributions, plus a 1% match on recurring deposits made through SoFi Invest taxable brokerage accounts.
- Possibly the ability to “schedule an unlimited number of appointments with a financial planner”, although I’m not sure of the quality of this advice. There is no indication you’re guaranteed at least a CFP. I’ve never used this feature, but it might be nice if you wanted to get some general advice.
Update April 2024: SoFi made a few notable changes recently, both positive and negative:
- The SoFi Unlimited 2% Credit Card added 10% boost on their rewards with direct deposit into SoFi Checking or Savings. This would work out to 2.2% cash back rewards points on everyday purchases. (As of December 2025, this is now restricted to SoFi Plus members paying $10 a month.)
- There is a new inactivity fee of $25 per account for every 6 months of login inactivity.
- The outgoing ACAT transfer fee was increased to $100. Previously $75.
Original post:

Valuation Gap Chart: US vs. International Developed vs. Emerging Markets
As 2025 winds down, you will probably read a lot of articles remarking how international stock indexes have outperformed US stock indexes like the S&P 500 by a significant amount this year. This hasn’t happened in a while! Yet, the following chart shows that the gap in valuations is still very wide.

Kraken Crypto: Existing Users 30 Days of Free Spins, New User Bonuses
Update: A quick heads up for existing Kraken users that many people are being targeted for another 30 days of their “Daily Spin” game given out to new users. You will need to make one trade to activate (even buying $1 of BTC or USDG and paying a penny fee works). Then you get 30 days of spins, like free slot machine pulls. The total average winnings over 30 days seem to be reliably at least around $15-$20. Check your offers tab; The e-mail subject was “🎄Spin to win up to $2,500 this Christmas!”, which looked a little spammy so you might have missed it.
Original post:
Crypto exchange Kraken is now offering up to a $150 bonus in crypto after you open a new account and complete the requirements. You can confirm when entering the code, as shown above. You must trade crypto that isn’t stablecoin, like BTC. The details are below. That’s my referral link, which should auto-populate with the promo code 2zr4jyp5 . Thanks if you use it!
- Open an account and deposit at least $100.
- Trade at least $100, earn $15.
- Trade at least $300, earn $20. ($35 total)
- Trade at least $500, earn $50. ($75 total)
- Trade at least $5,000, earn $75. ($150 total)
Select cashback portals are offering bonuses as well, which change regularly but can be upward of $100 as well, like TopCashback and Rakuten (search “Kraken”). The payouts vary up to daily, but I would wait until one is above $100, currently Rakuten is at $150 at time of writing (Hat tip to DoC). I am not 100% certain if this will stack with the referral discount, but I would still try going through the portal link and then adding the referral code. There are multiple successful reports of stacking.
Be on the lookout for a Daily Spin game which offers free spins for 30 days as well.
Other crypto offers:
- Gemini $50 bonus after trading $100.
- OKX $150 bonus after depositing and trading $200 of crypto.
Best Interest Rates Survey: Bank Accounts, Treasury Bills, Money Markets, ETFs – December 2025
Here’s my monthly survey of the best interest rates on cash as of December 2025, roughly sorted from shortest to longest maturities. Banks and brokerages love taking advantage of idle cash, and you can often earning more money while keeping the same level of safety by moving to another FDIC-insured bank or NCUA-insured credit union. Check out my Ultimate Rate-Chaser Calculator to see how much extra interest you could earn from switching. Rates listed are available to everyone nationwide. Rates checked as of 12/5/2025.
TL;DR: Savings account interest rates have dropped slightly overall, moving with Fed rates. You can still get 4.6% and 4.5% APY if you accept some hoops/restrictions, but most are a little under 4% now. Short-term T-Bill rates have fallen, now ~3.7%. Top 5-year CD rates are ~4.25% APY, while 5-year Treasury rate is ~3.7%.
High-yield savings accounts*
Since the huge megabanks still pay essentially no interest, everyone should at least have a separate, no-fee online savings account to piggy-back onto your existing checking account. The interest rates on savings accounts can drop at any time, so I list the top rates as well as competitive rates from banks with a history of competitive rates and solid user experience. Some banks will bait you with a temporary top rate and then lower the rates in the hopes that you are too lazy to leave.
- The top saving rate at the moment: Pibank at 4.60% APY (no min), but they have some weird restrictions; like you can only use wire/Plaid to deposit and wire transfers to withdraw funds?! Hyperion Bank has a 4.50% APY money market account ($10,000 minimum, new money) with a 6-month rate guarantee. CIT Platinum Savings is now at 3.75% APY with $5,000+ balance and is offering an up to $300 deposit bonus which increases your effective APY for a while. There are many banks in between.
- SoFi Bank is at 3.60% APY + up to 4.30% APY for 6 months + $325 new account bonus with qualifying direct deposit. You must maintain a direct deposit of any amount (even $1) each month for the higher APY. SoFi has historically competitive rates and full banking features.
- Here is a limited survey of high-yield savings accounts. They aren’t the top rates, but a group that have historically kept it relatively competitive such that I like to track their history. This month they start at 3.30% APY on up.
Short-term guaranteed rates (1 year and under)
A common question is what to do with a big pile of cash that you’re waiting to deploy shortly (plan to buy a house soon, just sold your house, just sold your business, legal settlement, inheritance). My usual advice is to keep things simple and take your time. If not a savings account, then put it in a flexible short-term CD under the FDIC limits until you have a plan.
- No Penalty CDs offer a fixed interest rate that can never go down, but you can still take out your money (once) without any fees if you want to use it elsewhere. Marcus has a 13-month No Penalty CD at 3.95% APY ($500 minimum deposit). Farmer’s Insurance FCU has a 9-month No Penalty CD at 4.00% APY ($1,000 minimum deposit). USALLIANCE Financial CU has a 11-month No Penalty CD at 3.90% APY ($500 minimum deposit).
- USALLIANCE Financial CU has a 12-month certificate at 4.18% APY ($500 min). Early withdrawal penalty is 180 days of interest. Anyone can join this credit union via partner organization American Consumer Council (try promo codes “consumer”, “abnb”, or “USFFCU” to join for free).
Money market mutual funds
Many brokerage firms that pay out very little interest on their default cash sweep funds (and keep the difference for themselves). Note: Money market mutual funds are highly-regulated, but ultimately not FDIC-insured, so I would still stick with highly reputable firms.
- Vanguard Federal Money Market Fund (VMFXX) is the default sweep option for Vanguard brokerage accounts, which has a 7-day SEC yield of 3.89% (changes daily, but also works out to a compound yield of 3.96%, which is better for comparing against APY). Odds are this is much higher than your own broker’s default cash sweep interest rate.
- Vanguard Treasury Money Market Fund (VUSXX) is an alternative money market fund which you must manually purchase, but the interest will be mostly (100% for 2024 tax year) exempt from state and local income taxes because it comes from qualifying US government obligations. Current 7-day SEC yield of 3.88% (compound yield of 3.95%).
Treasury Bills and Ultra-short Treasury ETFs
Another option is to buy individual Treasury bills which come in a variety of maturities from 4-weeks to 52-weeks and are fully backed by the US government. You can also invest in ETFs that hold a rotating basket of short-term Treasury Bills for you, while charging a small management fee for doing so. T-bill interest is exempt from state and local income taxes, which can make a significant difference in your effective yield.
- You can build your own T-Bill ladder at TreasuryDirect.gov or via a brokerage account with a bond desk like Vanguard and Fidelity. Here are the current Treasury Bill rates. As of 12/5/25, a new 4-week T-Bill had the equivalent of 3.72% annualized interest and a 52-week T-Bill had the equivalent of 3.61% annualized interest.
- The iShares 0-3 Month Treasury Bond ETF (SGOV) has a 3.85% 30-day SEC yield (0.09% expense ratio) and effective duration of 0.10 years. SPDR Bloomberg Barclays 1-3 Month T-Bill ETF (BIL) has a 3.71% 30-day SEC yield (0.136% expense ratio) and effective duration of 0.15 years. The new Vanguard 0-3 Month Treasury Bill ETF (VBIL) has a 3.89% 30-day SEC yield (0.07% expense ratio) and effective duration of 0.10 years.
US Savings Bonds
Series I Savings Bonds offer rates that are linked to inflation and backed by the US government. You must hold them for at least a year. If you redeem them within 5 years there is a penalty of the last 3 months of interest. The annual purchase limit for electronic I bonds is $10,000 per Social Security Number, available online at TreasuryDirect.gov.
- “I Bonds” bought between November 2025 and April 2026 will earn a 4.03% rate for the first six months. The rate of the subsequent 6-month period will be based on inflation again. More on Savings Bonds here.
- In mid-April 2026, the CPI will be announced and you will have a short period where you will have a very close estimate of the rate for the next 12 months. I will post another update at that time.
Rewards checking accounts
These unique checking accounts pay above-average interest rates, but with unique risks. You have to jump through certain hoops which usually involve 10+ debit card purchases each cycle, a certain number of ACH/direct deposits, and/or a certain number of logins per month. If you make a mistake (or they judge that you did) you risk earning zero interest for that month. Some folks don’t mind the extra work and attention required, while others would rather not bother. Rates can also drop suddenly, leaving a “bait-and-switch” feeling.
- OnPath Federal Credit Union (my review) pays 6.00% APY on up to $10,000 if you make 15 debit card purchases, opt into online statements, and login to online or mobile banking once per statement cycle. Anyone can join this credit union via $5 membership fee to join partner organization. You can also get a $150 Visa Reward card when you open a new account and make qualifying transactions.
- Genisys Credit Union pays 6.75% APY on up to $7,500 if you make 10 debit card purchases of $5+ each per statement cycle, and opt into online statements. Anyone can join this credit union via $5 membership fee to join partner organization.
- Oklahoma Central Credit Union pays 6.00% APY on up to $10,000 if you make 15 debit card purchases (non-ATM) per statement cycle. Anyone can join this credit union if they are “affiliated with another credit union”.
- La Capitol Federal Credit Union pays 5.75% APY on up to $10,000 if you make 15 debit card purchases of at least $5 each per statement cycle. Anyone can join this credit union via partner organization, Louisiana Association for Personal Financial Achievement ($20).
- First Southern Bank pays 5.50% APY on up to $25,000 if you make at least 15 debit card purchases, 1 ACH credit or payment transaction, and enroll in online statements.
- Credit Union of New Jersey pays 6.00% APY on up to $25,000 if you make 12 debit card purchases, opt into online statements, and make at least 1 direct deposit, online bill payment, or automatic payment (ACH) per statement cycle. Anyone can join this credit union via $5 membership fee to join partner organization.
- Andrews Federal Credit Union pays 5.50% APY (down from 6%) on up to $25,000 if you make 15 debit card purchases, opt into online statements, and make at least 1 direct deposit or ACH transaction per statement cycle. Anyone can join this credit union via partner organization.
- Find a locally-restricted rewards checking account at DepositAccounts.
Certificates of deposit (greater than 1 year)
CDs offer higher rates, but come with an early withdrawal penalty. By finding a bank CD with a reasonable early withdrawal penalty, you can enjoy higher rates but maintain access in a true emergency. Alternatively, consider building a CD ladder of different maturity lengths (ex. 1/2/3/4/5-years) such that you have access to part of the ladder each year, but your blended interest rate is higher than a savings account. When one CD matures, use that money to buy another 5-year CD to keep the ladder going. Some CDs also offer “add-ons” where you can deposit more funds if rates drop.
- United Fidelity Bank has a 5-year certificate at 4.25% APY ($1,000 minimum), 4-year at 4.20% APY, 3-year at 4.20% APY, 2-year at 4.25% APY, and 1.5-year at 4.15% APY. Early withdrawal penalties are not disclosed clearly online.
- Mountain America Credit Union (MACU) has a 5-year certificate at 4.00% APY ($500 minimum), 4-year at 4.00% APY, 3-year at 4.05% APY, 2-year at 4.20% APY, and 1-year at 3.85% APY. Early withdrawal penalty for the 4-year and 5-year is 365 days of interest. Anyone can join this credit union via partner organization American Consumer Council (use promo code “consumer” when joining).
- You can buy certificates of deposit via the bond desks of Vanguard and Fidelity. You may need an account to see the rates. These “brokered CDs” offer FDIC insurance and easy laddering, but they don’t come with predictable early withdrawal penalties. Right now, I see a 5-year non-callable brokered CD at 3.90% APY (callable: no, call protection: yes). Be warned that both Vanguard and Fidelity will list higher rates from callable CDs, which importantly means they can (and will!) call back your CD if rates drop significantly later.
Longer-term Instruments
I’d use these with caution due to increased interest rate risk (tbh, I don’t use them at all), but I still track them to see the rest of the current yield curve.
- Willing to lock up your money for 10 years? You can buy long-term certificates of deposit via the bond desks of Vanguard and Fidelity. These “brokered CDs” offer FDIC insurance, but they don’t come with predictable early withdrawal penalties. You might find something that pays more than your other brokerage cash and Treasury options. Right now, I see a 10-year CDs at 4.00% (non-callable) vs. 4.13% for a 10-year Treasury. Watch out for higher rates from callable CDs where they can call your CD back if interest rates drop.
All rates were checked as of 12/5/25.
* I no longer recommend fintech companies due to the possibility of significant loss due to poor recordkeeping and the lack of government protection in such scenarios. The point of cash is absolute safety of principal.
