India’s UPI is national service so fraud is “relatively easy” to combat but it depends on banks’ responsiveness.

However, i heard from my Indian friends is that UPI fraud is on the raise and becoming a big challenge.

Edit: UPI fraud rate is similar to CC fraud rate but only about ~6 % of the money lost to UPI fraud has been recovered. If this trend continues (fraud pct continues to grow and recovery rate does not improve) UPI system might get into trouble.

Btw, the stats say that the UPI fraud rate is doubling every year for past few years.
