Update 1 adds what this blogger said yesterday and what he said six years ago.

Once the Chinese yuan will be convertible,
it will be this planet’s reserve currency,
says Hans Redeker, global head of FX strategy at BNP Paribas,
answering readers’ questions on the many faces, including its future-or-not as reserve currency, of the US dollar in the Financial Times.

The dollar is still the world’s major reserve currency with latest IMF data suggesting 62 per cent of the world’s currency reserves held in dollars. [...]
The discussion concerning the reallocation of currency reserves out of dollars misses another important point: Namely, which currency qualifies as the next reserve currency?
The euro has balanced foreign balances, but has no surpluses. China has massive surpluses, but its currency is NOT CONVERTIBLE. The ruble does not qualify due to its unstable domestic banking system. In short, as long as China runs a regulated currency regime there is no credible alternative to the dollar as a reserve currency.
Summing up: In the next couple of years, the dollar should be steadier than many may think today. UNSNIP

AS I SAID YESTERDAY:
[…] China and the Association of South-East Asian Nations (ASEAN) […are] decoupling from the West.
The decoupling process may be strengthened by an emerging hard currency in the region, China’s yuan. (1)

AS I SAID SIX YEARS AGO:
