Stablecoins as Shadow Reserves: Finance Without a Safety Net
In the long history of money, reserves have been the ballast that steadies the system. Central banks hold gold or dollars to reassure markets that when turbulence strikes, redemption is possible.

To traders in crypto markets, they are the grease that keeps transactions flowing. To investors in emerging economies, they have become a lifeline—an unofficial dollarization for those wary of local inflation.
