PIX, UPI, Interac & Osko: Instant Payments Around the World
While the US debated instant payments, much of the world just built them. Brazil and India now run two of the largest real-time payment systems on Earth, and for hundreds of millions of people "bank transfer" already means "arrives before the conversation ends." Here's how the big four behave, and their quirks.
PIX in Brazil
Launched by the central bank in 2020, PIX became the default way Brazilians pay for nearly everything. Transfers clear in seconds (the system targets ~10 seconds end to end), 24/7, addressed by keys (a phone number, email, tax ID or random key) instead of account numbers.
- Quirk: to fight kidnapping-related coercion, nighttime transfers (typically 8 PM–6 AM) have a default R$1,000 limit unless you've raised it in advance.
UPI in India
The Unified Payments Interface processes more than a billion transactions a month across hundreds of banks through apps like PhonePe, Google Pay and Paytm. Payments settle in seconds, 24/7, addressed to a virtual payment address (name@bank).
- Quirk: per-day caps (commonly ₹1 lakh, higher for specific categories) and occasional bank-app outages that queue rather than fail payments.
Interac e-Transfer in Canada
Canada's e-Transfer is near-universal and runs 24/7, but with a twist the others don't have: unless the recipient enabled Autodeposit, they must click the notification and accept the transfer. The money is typically available to accept within minutes (Interac quotes up to 30), but the clock includes a human.
- Quirk: "Where's my e-Transfer?" is usually "check your spam folder," not a payments problem.
NPP and Osko in Australia
The New Payments Platform (branded Osko in banking apps, with PayID addressing) clears payments in under a minute, 24/7. Nearly all consumer accounts are reachable.
- Quirk: banks aggressively hold first payments to new payees for fraud review; subsequent payments to the same payee fly.
The pattern (and the catch)
| System | Country | Typical speed | Hours |
|---|---|---|---|
| PIX | Brazil | seconds | 24/7/365 |
| UPI | India | seconds | 24/7/365 |
| Interac e-Transfer | Canada | minutes (+ acceptance) | 24/7/365 |
| NPP / Osko | Australia | < 1 minute | 24/7/365 |
The catch: these are all domestic rails. Money entering Brazil, India, Canada or Australia from abroad still arrives by SWIFT (or a fintech's local settlement network). The instant rail only carries the final domestic leg. That's why an international transfer to a PIX-enabled account can still take two days: the last 10 seconds were never the problem.
So when you send money into one of these countries from abroad, the useful question isn't whether the local rail is fast (it is), but how quickly your provider hands off to it. Specialist remittance services connect directly into these domestic rails, which is why they can quote a delivery time your bank usually can't. Price your bank's transfer first, then compare at least one specialist for your exact corridor, since costs swing widely by country pair and payout method.
Partner link One such service, which hands off into these domestic rails:
- Remitly, whose faster tier is priced separately from its economy tier.
The speed you are buying is the hand-off, not the local rail: PIX, UPI, Interac and Osko are already near-instant and free at the destination end. Quote it against your bank for your exact corridor, since the same service can rank differently country to country.
