This article is extremely poorly written and smacks of yellow journalism.
No other currency in the world has the liquidity that the USD provides, regardless of current valuation trends, and the USD makes up 63% of all central bank reserves across the globe.
We saw the USD go lower in the late 70s and early 80s, and if anyone thinks we're remotely close to have any currency supplant the USD as the reserve currency, they're delusional and/or buying into the goldbug BS.
Once any significant pullback occurs, as Wall Street and Main Street intersect once again, the USD will rally furiously.
p.s. - Most exporting nations are in a race to devalue their currencies.
