SEC Gives DTCC OK to Tokenize Stocks In Move To Blockchain

Slashdot.org - Fri, 12/12/2025 - 05:00
The SEC has granted the Depository Trust & Clearing Corp., or DTCC, a no-action letter allowing it to custody and recognize tokenized stocks, ETFs, and Treasuries on approved blockchains for three years. "Although this program is a pilot subject to various operational limitations, it marks a significant incremental step in moving markets onchain," SEC Commissioner Hester Peirce said in a statement. Bloomberg reports: With the permission, DTCC will also extend their record-keeping to the blockchain, Michael Winnike, global head of strategy and market solutions at DTCC Clearing & Securities Services, said in an interview. "It's the same legal entitlement, the same stock that you would hold in your account from the DTCC in traditional form," Winnike said. [...] The SEC's authorization of tokenization services only applies to a specific set of securities that trade often. The approval includes the Russell 1000 index which represents the 1,000 largest publicly traded US companies, as well as exchange-traded funds that track major indices and US Treasury bills, bonds and notes, Winnike said. "This allows us both to create value for the markets, while staying in a pre-defined pool of highly-liquid securities to start," said Winnike. The firm's ultimate aspiration is to add its entire depository, which represents $100 trillion in securities, to the blockchain, a move that would require further expansion of the no-action relief from the SEC, he said. Winnike said the tokenization service will help bridge the traditional and digital worlds in part because the new technology will have the same legal entitlements and controls as traditional markets, including freezing or forced transfers if assets are stolen. "This enables participants to adopt and integrate, because they know there is a trusted party that can recover their securities as needed" and can address potential errors, he said. The new blockchain service will also allow investors to move assets all the time, not just Monday through Friday when traditional markets are open. "That creates a lot of new utility," Winnike said. "It brings the two ecosystems together."

LifeX TIPS ETFs: Monthly Inflation-Adjusted Income

MyMoneyBlog.com - Fri, 12/12/2025 - 02:11

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. Inflation was relatively mild for a long time until recently, but historically it has been a significant risk factor.

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 this year, but that number would increase with CPI inflation each year for 30 years (through the year 2055). At 3% average inflation, your 30th year’s income would have grown to over $100,000 a year. Of course, inflation could be a lot higher, which is why no private insurance company will sell you inflation protection over such a long period of time.

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.

Cadmium Zinc Telluride: The Wonder Material Powering a Medical 'Revolution'

Slashdot.org - Fri, 12/12/2025 - 02:00
Cadmium zinc telluride (CZT), a hard-to-manufacture semiconductor produced by only a handful of companies, is enabling a quiet revolution in medical imaging, science, and security by delivering faster scans, lower radiation doses, and far more precise X-ray and gamma-ray detection. "You get beautiful pictures from this scanner," says Dr Kshama Wechalekar, head of nuclear medicine and PET. "It's an amazing feat of engineering and physics." The BBC reports: Kromek is one of just a few firms in the world that can make CZT. You may never have heard of the stuff but, in Dr Wechalekar's words, it is enabling a "revolution" in medical imaging. This wonder material has many other uses, such as in X-ray telescopes, radiation detectors and airport security scanners. And it is increasingly sought-after. Investigations of patients' lungs performed by Dr Wechalekar and her colleagues involve looking for the presence of many tiny blood clots in people with long Covid, or a larger clot known as a pulmonary embolism, for example. The 1-million-pound scanner works by detecting gamma rays emitted by a radioactive substance that is injected into patients' bodies. But the scanner's sensitivity means less of this substance is needed than before: "We can reduce doses about 30%," says Dr Wechalekar. While CZT-based scanners are not new in general, large, whole-body scanners such as this one are a relatively recent innovation. CZT itself has been around for decades but it is notoriously difficult to manufacture. "It has taken a long time for it to develop into an industrial-scale production process," says Arnab Basu, founding chief executive of Kromek. [...] The newly formed CZT, a semiconductor, can detect tiny photon particles in X-rays and gamma rays with incredible precision -- like a highly specialized version of the light-sensing, silicon-based image sensor in your smartphone camera. Whenever a high energy photon strikes the CZT, it mobilizes an electron and this electrical signal can be used to make an image. Earlier scanner technology used a two-step process, which was not as precise. "It's digital," says Dr Basu. "It's a single conversion step. It retains all the important information such as timing, the energy of the X-ray that is hitting the CZT detector -- you can create color, or spectroscopic images."
