Is there a real alternative to the dollar and Treasury market?
Core argument: The dollar is involved in some 90% of foreign-exchange trades and accounts for almost 60% of central bank reserves, with no real competitor capable of filling any void it leaves.
However much the financial world’s faith in the US has been shaken, it’s short of immediate alternatives. European assets suddenly look somewhat more appealing, but nothing can match the depth and liquidity of the nearly-$29 trillion Treasury market. The dollar is involved in some 90% of foreign-exchange trades and accounts for almost 60% of central bank reserves. It has no real competitor capable of filling any void: The euro still lacks the depth of debt instruments required of a reserve asset and perhaps still the political ties across its 20-strong membership, and China’s yuan is managed by its government. For all these reasons, any so-called regime shift away from the dollar “could well hit its limits soon,” says Eswar Prasad, a professor at Cornell University and author of 2014's "The Dollar Trap." “Rebuilding institutions and foreign investors’ trust in them will be a long and arduous process, if and when it starts,” he says. “But the US certainly has the luxury of not having any serious rival to its financial markets and currency.”
