U.S. Treasury Secretary Mnuchin dismissed concerns that the dollar's recent drop threatens its global dominance.  
He said, "Dollar prices don’t reflect our strong-dollar policy, which focuses on long-term measures to keep it as the reserve currency."  
Mnuchin believes Trump’s policies, like the GOP tax bill, support this goal.  
The dollar fell 11% this year, its worst first half since 1973, amid worries over tariffs and strained alliances.  
He argues these policies still fuel growth.

Mnuchin's confidence in the dollar's long-term strength is totally uplifting, showing how solid policies can keep it shining bright despite short-term dips
