Copper and base metals rose on July 30 as the dollar fell to one-week lows after the Fed kept rates steady. LME three-month copper rose 0.75% to $13,676 a tonne, and aluminium also gained on Middle East supply disruptions.
Markets priced a 58% chance of a September hike, down from 81% before the statement.
A weaker dollar and lower hike odds support metals and other dollar-priced commodities. Supply tightness in aluminium from the Middle East adds upward pressure.
After 1,637 past bearish macro events, US Dollar (Broad) moved a median -0.2% over 5 sessions (39% higher; middle half -0.6% to +0.3%), and -0.2% over 20.
