(Bloomberg) — A new cryptocurrency aims to occupy the final frontier of investor safety — cash that doesn’t lose purchasing power to inflation.

USDi, being launched by two veterans of US inflation-protected and foreign-exchange derivatives, is a dollar tracking stablecoin whose value is determined by the increase in the US consumer price index since December 2024. On April 15, it was $1.00863.

Inflation protection in US markets has been available to investors since 1997 via Treasury inflation-protected securities, or TIPS — government bonds whose principal is indexed to the US consumer price index, or CPI. But as bonds, they’re subject to losses when interest rates rise, an outcome that took by surprise some of the investors who piled into TIPS ETFs as inflation accelerated in 2021.

USDi is comparable to TIPS principal or, theoretically, to an inflation-protected savings account, if such a thing existed, according to Michael Ashton, who began his career in inflation-protected investing at Barclays Plc in the early 2000s.

“The riskless asset doesn’t actually currently exist, and that’s inflation-linked cash,” Ashton said. “Holding cash is an option on future opportunities, and the cost of that option is inflation. If you create inflation-linked cash, that’s the end of the risk line.”

As described by USDi Partners LLC in a statement, the token will have as much purchasing power as the dollar did in December 2024. USDi will mint and burn the coin at its stated value, which, like TIPS principal, will be a function of that day’s CPI.

While the government publishes CPI only once a month, it interpolates daily values that TIPS investors use to calculate accrued interest. CPI values determine TIPS and USDi index values with a two-month lag, meaning that the December CPI maps to March 1, and values have been published through May 31. The April 15 value of USDi is calculated by dividing that day’s CPI — interpolated between the January and February monthly values — by the December CPI, which will always be the denominator in the equation.

It’s different in that sense from stablecoins whose value is pegged to the dollar — of which there are dozens, with combined market value exceeding $200 billion. Initially they were used primarily as a conduit for trading other cryptocurrencies. Newer tokens have been created for use as collateral.
