The ongoing charge figure (OCF) for 10 funds which all track S&P indices will be reduced to 0.14% from 0.3% previously.
The $573.4m technology ETF is the largest fund affected, followed by the $465m S&P US Financials Sector ETF and the $265.3m S&P Energy Sector Ucits ETF.
In total the changes apply to $1.8bn (£1.4bn) worth of assets.
The products are part of the $18bn stable of Source-managed ETFs Invesco acquired in April 2017.
Just over half of discretionary fund managers (DFMs) are currently using sector ETFs, according to SPDR research published in May.
