One further privilege: Foreigners hold $950 billion dollars of USD banknotes – interest free lending to the US Treasury.
Could BRICS counter this privilege by denominating their intra-BRICS trade in a member’s currency, such as the yuan (RMB)?
Saudi Arabia already denominates some of its oil exports to China in RMB. But unless the Saudis want to hold RMB assets in their foreign-currency reserves, they sell the RMB to buy assets in more-tradable currencies, mainly USD. Perhaps this allows the oil transaction to bypass the SWIFT international payments system and any threat of US currency sanctions, but if the Saudis want convertible currency as payment for their oil, they still need dollars. And it is the attractiveness of the USD as a reserve currency – not its trade-denomination role – which gives the United States an advantage in funding its chronic external deficits.
The more radical currency suggestions seem uniformly infeasible. The idea of a common currency (like the euro) was, unsurprisingly, dismissed by O’Neill as “ridiculous”. Returning to the gold standard is equally fanciful: it broke down because it required more discipline than governments could provide.
What about a multi-currency basket to replace the USD in intra-BRICS trade and capital flows? Something like the IMF’s synthetic reserve-unit, Special Drawing Rights (SDRs)? A basket made up of BRICS currencies would include a Russian ruble component – hardly an advantage in current circumstances. A basket based on convertible currencies (more akin to SDRs) requires a central authority to administer it, with a balance sheet of the component currencies, ready to provide liquidity.
All these possibilities run into the same obstacle: intra-BRICS trade balances overwhelmingly put China (and Saudi Arabia, in the enlarged group) in surplus. Unless there is a mechanism for equilibrating these inter-country imbalances, any common-currency system would quickly break down, with the surplus countries accumulating all the BRICS-currency.
On a different tack, would the BRICS’ New Development Bank (NDB) represent a substantial new source of development funding? The suggestion is that the NDB could issue debt and lend in the borrowing countries’ currency, thus removing foreign currency risk for the borrower.
Risk can be shifted to others, but rarely can it be extinguished. Either the NDB or the funder is bearing the currency risk. And, of course, someone is bearing the risk of lending to low-creditworthy borrowers. Thus, the NDB will be in the familiar position of all multilateral development banks, with tight constraints on how much it can sensibly lend.
And besides, so far, the NDB has lent $32 billion – a tiny sum, just a few percent of China’s Belt and Road Initiative.
What conclusion might be drawn? There is prestige in your currency being widely used globally, so China may be prepared to wear some of the costs of creating a role for the RMB in BRICS trade and investment. China (and perhaps Saudi Arabia also) have an interest in facilitating non-USD foreign investments as outlets for their trade surpluses.
It seems likely that China will play an important development role in Africa and South America in the future, and the related financial transactions might be placed within the BRICS framework to give the grouping some semblance of economic substance. But these developments will be constrained by the same realities that apply without the BRICS framework. Namely, that China wants to make profitable investments and get repaid.
So much (or so little) for the currency economics. That leaves whatever soft-power benefits come from developing a rival to the Western-dominated international order. It is even possible that this might hasten the adaptation of the Bretton Woods institutions to a world no longer dominated by its founding countries. Let’s wait and see.
