In a big collaboration, Mastercard and some big American banks are trying out new technology to make it easier to trade digital assets. These assets are things like money from commercial banks, government bonds, and other types of loans. They want to make transactions in dollars faster and safer by using what's called a Regulated Settlement Network. This is like a test to see if it works.

The new technology could change how money moves around the world. Right now, different types of money and loans use different systems to trade. But if they become digital tokens on one system, it could make trading faster and simpler. This trial is building on another test done in 2022, which looked at how to move money between banks in the US and across borders.

Some big names are taking part in this trial, like Citigroup, JPMorgan Chase, Visa, Swift, and others. They've got help from experts like the Bank of New York Mellon and the International Swaps and Derivatives Association. But even though they're trying it out, it doesn't mean they'll use it for real.

At the same time, big banks in the US are asking the government to help them join the new Bitcoin market. They've sent a letter to the Securities and Exchange Commission, asking for changes to some rules. This comes as another bank, Republic First Bank, closed down recently. It's the second time it's happened, showing there are still problems in the banking world that need fixing.

In conclusion, Mastercard and US banks are testing new technology to make trading digital assets faster and safer. They're also asking the government for help to join the Bitcoin market. But with some banks still facing challenges, it's clear there's work to be done to make the banking system stronger.
