China's reserve outflow episode (2015-2016)
Fears of yuan devaluation triggered massive capital outflows. China's reserves fell by about $1 trillion from a peak near $4 trillion as Beijing spent dollars defending the currency.
Beijing burned through reserves, imposed capital controls, and stabilized the yuan.
It showed Beijing treats reserve allocation as a deliberate policy tool and will shift positions when it perceives risk.
Today's Treasury sell-down is similar reserve management — slower and more strategic than the 2015 panic, but the same willingness to move money for policy reasons.
