Amazing article, Luca. Loved it. Thanks for it. Reading your text I saw no mention to the fact of the current traditional financial system works with fractional reserves, and if I understood it correctly, your New monetary triangle (CBDC or CBDC+stablecoin system) suggests that we would have a system that would be full collateralized by Central Bank money. what are your thoughts on this? And again, thx for the text. I love it. And also as a Cyclist too the introduction was just perfect. ;)

Great piece, thanks Luca! I've been organizing my sporadic thoughts on how primitives in defi can make the banking system more stable and looking for thought experiments in this realm -- seems like I've finally found it.

In your new system, seems like depositors have no choice in choosing their counterparties (ie. the state treasury / central bank solely manage that). That's fair and suitable for retails since most don't want to bother with selecting counterparties when depositing. However, completely removing the market from influencing where capital flows and centralize that power to the central bank looks concerning to me. How are you thinking of making sure the most efficiently run banks stand out and get the liquidity they deserve?

I've been thinking through a model in which depositors deposit with commercial banks, having all deposit as mid to long-term but the receipts of deposit can be used as money -- making it even the long-term deposits convenient to use for commercial activities. In this scenario, banks put up a certain percentage of capital as collateral to "lever up" (ie. taking deposits). The revenue of the lever up is split between bank and their depositors by a certain ratio, similar to the GP/LP incentives structure in VC/PE, and with the bank's collateral as a buffer if anything goes south.

Would love to hear your thoughts. In general, I like how defi CDP can "make any relatively liquid assets / claims function like cash" and think this primitive shift can go very far in shaping the new financial system
