Quick answer: SWIFT gpi is a service SWIFT launched in 2017 that lets banks track a cross-border payment end to end, see the fees taken out, and speed up delivery. ACI Worldwide is a software vendor that connects banks to gpi and to real-time payment schemes. Domestic instant rails like FedNow and The Clearing House RTP settle within seconds, and together these systems are rebuilding how money moves across borders.

Cross-border payments used to be a black box: you sent money and hoped it arrived, with no way to see where it was or what got deducted. The rails described here are the response to that. This is a plain-language walkthrough of what SWIFT gpi actually does, what ACI Worldwide’s role is, and how domestic real-time systems fit alongside it. One caution up front, since it is a common mix-up: none of this is SWIFT integrating Ripple.
What SWIFT gpi is
According to ACI’s SWIFT gpi explainer, gpi launched in 2017 to give “visibility into the status of cross-border payments, to improve payment processing speeds, and to ensure that creditors received the full amount promised.” It does three things: it tracks, it shows fees, and it moves faster than the old correspondent-banking flow.
The tracking piece is the key idea. Every gpi payment gets a Unique End-to-end Transaction Reference (UETR) that banks update in SWIFT’s central Tracker, so the sender can follow it through each intermediary. On speed, the page reports that 75 percent of cross-border payments reach beneficiary banks within 10 minutes, and almost 100 percent within 24 hours. On adoption, it cites over 4,450 financial institutions using gpi, moving more than $300 billion a day.
Where ACI Worldwide fits
SWIFT sets the standard and runs the Tracker; banks still need software to connect. That is ACI’s role. Its ACI and SWIFT page describes the company as “the first certified vendor of SWIFT gpi solutions and a SWIFT partner for more than 20 years,” and says ACI “supports around 9 percent of global SWIFT traffic and approximately 30 percent in the US.”
Here is the part that gets misread. The same page says ACI’s platform lets “any bank use Real-time Payment Systems to support SWIFT FIN, gpi, DLT (e.g. Ripple), Wire and immediate payments.” That is ACI’s own product supporting several rails, including a distributed-ledger option, as choices a bank can route through. It is not SWIFT adopting Ripple, and it is not Ripple replacing SWIFT. The distinction matters because the two are often conflated in headlines.
Real-time rails: FedNow and RTP
SWIFT gpi is about cross-border. Inside a country, a different set of rails clears payments instantly. ACI’s US real-time payments page notes there are more than 50 real-time payment schemes live worldwide, up from 40 in 2018.
In the US, two systems anchor this. The Clearing House operates the RTP network, owned by a group of large commercial banks, clearing and settling payments in real time. And the Federal Reserve’s FedNow Service went live on July 20, 2023, providing “interbank clearing and settlement that enables funds to be transferred” in near real time, designed for “uninterrupted 24x7x365 processing.” A cross-border payment increasingly hands off to one of these domestic instant rails on the receiving end, which is why gpi speed and local real-time speed are two halves of the same journey.
ISO 20022: the data layer
Speed is only half the upgrade. The other half is richer data. The industry is moving payment messaging to the ISO 20022 standard, which carries far more structured information than the legacy formats. For cross-border payments and reporting (CBPR+), the coexistence period between old and new message formats ended in late November 2025, so structured ISO 20022 data is now the baseline. Better data is what makes automated tracking, compliance screening, and reconciliation faster, and it is a prerequisite for the straight-through processing that both gpi and real-time rails depend on.
Why this matters
Payments infrastructure is a repeat-use case, not a one-time event. Every one of these transactions needs a reliable network and a settlement asset, which is why banks, card networks, and ledger projects all compete for the same flows. The Bank for International Settlements frames where this could head next: it argues “tokenisation could dramatically enhance the capabilities of the monetary and financial system” by removing “the traditional separation of messaging, reconciliation and settlement” through a unified ledger. Whether the future rail is an upgraded SWIFT, a domestic instant scheme, a distributed ledger such as Ripple’s, or a mix, the direction is the same: track everything, settle faster, carry better data. The G20’s cross-border payments roadmap points the same way, targeting most cross-border payments reaching recipients within one hour by the end of 2027.
Common questions
What is SWIFT gpi?
SWIFT gpi is a service SWIFT launched in 2017 to improve cross-border payments. It gives each payment a Unique End-to-end Transaction Reference that banks update in a central Tracker, so senders can follow the payment, see fees deducted along the way, and receive faster delivery. ACI reports that 75 percent of cross-border payments reach beneficiary banks within 10 minutes.
Is SWIFT integrating Ripple?
No. ACI Worldwide’s own platform can route payments across several rails, including SWIFT gpi and a distributed-ledger option such as Ripple, as separate choices a bank can use. That is an ACI product capability, not SWIFT adopting Ripple or Ripple replacing SWIFT.
What does ACI Worldwide do in payments?
ACI Worldwide is a payments software vendor that connects banks to SWIFT and to real-time payment schemes. It describes itself as the first certified vendor of SWIFT gpi solutions, a SWIFT partner for over 20 years, and says it supports around 9 percent of global SWIFT traffic and roughly 30 percent in the US.
What is the difference between SWIFT gpi and FedNow?
SWIFT gpi is for cross-border payments between banks in different countries, focused on tracking, transparency, and speed. FedNow is a US domestic instant-payment service run by the Federal Reserve that settles payments in near real time, 24x7x365. A cross-border payment often hands off to a domestic real-time rail like FedNow or RTP on the receiving end.
What is ISO 20022 and why does it matter for cross-border payments?
ISO 20022 is a messaging standard that carries richer, more structured payment data than legacy formats. For cross-border payments and reporting, the coexistence period between old and new formats ended in late November 2025, making ISO 20022 the baseline. Better structured data supports faster automated tracking, compliance screening, and reconciliation.
