Risk monitoring - Nacha frequently surveys financial institutions about Same Day ACH and risk management. In the most recent survey following the March 2020 dollar limit increase, zero financial institutions responded that they had experienced an increase in fraud that is directly attributable to the increase in the Same Day ACH dollar limit. 
  • All of the responding financial institutions allow their ACH origination clients to originate Same Day ACH payments up to the new $100,000 limit

Existing use cases would be improved by making a greater percentage eligible for Same Day ACH, such as for:
  • Business-to-business payments
  • Tax payments
  • Payroll funding
  • Insurance claim payments
  • Merchant settlement
  • Same Day Reversals of standard ACH payments
  • Business continuity - recovery from missed deadlines or outages
A greater percentage of ACH dollar volume becomes eligible for Same Day ACH
  • The percentage of ACH dollars eligible for Same Day ACH would more than double 
  • An additional 3.5% of B2B payments will become eligible for Same Day ACH
Anticipated Impacts
A dollar limit increase would result in a larger amount of dollars settling at several times throughout the day – 1:00 p.m.; 5:00 p.m., and 6:00 p.m. (all in ET).
All ACH participants should understand and plan for these dollar flows within their organizations. 
  • ODFIs need to determine whether to offer higher dollar limits to Same Day ACH Originators
    • Higher Same Day ACH dollar limits might impact a financial institution’s assessment of its customers’ credit risks

RFC Summary

In December 2020, Nacha issued a Request For Comment for a proposal to increase the Same Day ACH dollar limit on a schedule of three increases over three consecutive years. By the third increase, the Same Day ACH dollar limit would have been eliminated. The increases would apply to all Same Day ACH payments; Consumer and business payments, credits and debits
The proposal would have given Nacha the ability to pause the scheduled effective dates for up to 6 months if operational, risk, or fraud issues arise. A 60-day notice would be given in the event of a pause. 
Responses to the RFC: 
107 responses were received to the RFC, including 68 financial institutions. FI respondents were well distributed among asset sizes
91% of respondents agreed that the current Same Day ACH dollar limit should be raised
85% agreed that all Same Day ACH entries should have the same limit 
60% said new/expanded use cases would be created by raising the dollar limit, such as: 
  • Payroll file funding; urgent large dollar vendor payments; auto dealer payments; corporate account transfers and cash management; and tax payments
  • Loan disbursements
  • Insurance claim payments
53% of respondents indicated a higher dollar limit would increase or significantly increase their usage of Same Day ACH
82% said impacts to their ACH operations and technology would be minimal-to-moderate
Respondents rated the impact on risk management as somewhat more impactful, though 60% still rated it as minimal-to-moderate 
71% of all respondents agreed that Same Day ACH payments should ultimately have the same limits as non-same day payments.
Nearly 70% of respondents supported raising the dollar limit in multiple scheduled increases.
  • Many respondents supported an increase to $1 million per eligible entry, but not subsequent increases without re-evaluation
  • Many respondents commented in support of an increase in March 2022, but not scheduled future increases
Changes from the original proposal in the RFC: 
This rule provides for a single increase of the limit to $1 million per entry, instead of three increases over three years
  • A sufficient percentage of respondents provided feedback and commentary that a single, incremental increase creates value for users of Same Day ACH, but that future increase should be deliberated after evaluation of this initial increase
  • Without multiple, future increases, there is not a need to provide for the ability to pause the schedule
