China Central Bank’s deputy governor, Lu Lei, recently explored the ideas of Nobel laureate Robert Mundell and Bitcoin’s elusive creator, Satoshi Nakamoto, in his new book. Both figures, Lu argues, left enduring marks on monetary theory, though their visions face challenges in today’s economy. Mundell, often called the “father of the euro,” laid the groundwork for single-currency areas, dreaming of a world where economies could unite under one currency to streamline trade and boost economic stability. His ideal of a “dollarization utopia,” however, never fully materialized. Satoshi Nakamoto’s vision for Bitcoin, introduced in 2008 as a revolutionary digital currency, promised financial freedom outside traditional banking systems. Yet, over time, Bitcoin transformed into a speculative asset, valued more as a store of wealth than as an everyday currency. Lu points out that Bitcoin’s rising value and energy-intensive mining process have distanced it from its original role. He highlights that mining the remaining two million Bitcoins now consumes enough power annually to support hundreds of millions of households, which conflicts with Mundell’s principles of efficiency and accessibility in currency design. These factors, Lu argues, make Bitcoin an imperfect solution for global monetary needs, despite its appeal as an alternative asset.

Here is What’s Behind Bitcoin’s Success, According to Crypto Expert In his book, Lu suggests that central banks face a crucial choice: adapt to the digital age or risk being left behind. He envisions central bank digital currencies (CBDCs) as a way to merge the innovation of digital assets with the stability that sovereign currencies provide. However, for CBDCs to succeed, he argues, they must address scalability and ensure monetary stability. Lu believes that while Bitcoin may have started the digital currency revolution, the future of money might rest on balancing technological progress with the core values of monetary sovereignty and stability, allowing central banks to remain relevant in an increasingly digital financial landscape.
