Despite their convenience, sweep accounts come with certain limitations that may impact overall effectiveness or suitability:
Variable Interest and Market Risk
Returns are not guaranteed. Money market funds and other short-term instruments used for sweeps are subject to interest rate fluctuations and, in some cases, credit or liquidity risks.
Transfer Timing and Delays
Sweeps typically execute post-business hours or at end-of-day processing. This means immediate fund needs or rapidly changing account balances may not trigger a sweep in real-time, potentially affecting liquidity.
Minimum Balance Requirements
Some banks mandate a minimum surplus before initiating a sweep. If balances regularly fall below this threshold, the feature may not activate, and idle funds remain unutilised.
Costs and Fees
Banks may impose fees for setting up and maintaining sweep arrangements. There could also be penalties for premature withdrawal of funds from fixed deposits or charges on liquid fund redemptions, which may erode the incremental yield.
Regulatory and Tax Impacts
Income from sweep-linked instruments may be taxable. Taxation depends on the investment product and the investor’s income bracket. Furthermore, regulatory norms may change, affecting product features or permissible instruments.
