Mark Zuckerberg will tell Congress that Libra can bring financial services to the world's 1.7 billion unbanked.
And if Libra doesn't do it, he said, China's new central-bank crypto will.
Facebook's CEO released his written testimony a day before his scheduled appearance before the U.S. House of Representatives Financial Services Committee, stating that Libra is envisioned as a global payments service that can help people send money more easily.
"The current system is failing them," Zuckerberg said. "The financial industry is stagnant and there is no digital financial architecture to support the innovation we need. I believe this problem can be solved, and Libra can help."
Notably, he highlighted Facebook's role – and the backlash the company has faced – in his remarks, writing:
Zuckerberg cautioned that the U.S. might lose its "financial leadership" on the world stage if Libra is not allowed to launch, noting that "China is moving quickly to launch similar ideas in the coming months."
He added that Facebook will not be part of launching Libra "anywhere in the world" until "all U.S. regulators" approve of the project, and will support delaying any launch until this has happened.
The CEO also emphasized that Facebook does not "expect to be leading" any efforts to further Libra's development given that the project's governing council, the Libra Association, has now been formally signed into existence with 21 members (including Calibra, a Facebook subsidiary, and Breakthrough Initiatives, a venture capital fund that Zuckerberg is involved in).
Zuckerberg claimed that Libra has no intention of competing with sovereign currencies or with participating in monetary policy, writing that it "is the province of central banks."
"[The Libra Association] will work with the Federal Reserve and other central banks responsible for monetary policy to make sure that is the case," he wrote.
The group even expects regulators to prohibit Libra from entering this space, he said, writing:
Zuckerberg even suggested that Libra may be better able to fight financial crimes than the existing system, noting that law enforcement agents can analyze on-chain activity and check know-your-customer information.
The Facebook CEO will be the second Facebook official to defend the cryptocurrency project before Congress, following his company's head of blockchain, David Marcus. Marcus testified before the Financial Services Committee (and its Senate counterpart) in July, articulating similar points about monetary policy.
