The impact of the COVID-19 pandemic on migrant remittances has generated a great deal of confusion and debate. This article aims to test three conflicting global and local narratives about the relationship between the pandemic and remittance flows in the South Africa–Zimbabwe remittance corridor. We refer to these as remittance pessimism, remittance resilience and remittance rerouting narratives. The article presents the pre-pandemic background context of migration from Zimbabwe to South Africa, the evidence for a shift from informal to formal remitting during the pandemic, and the implications of the remittance rerouting narrative for other corridors. We find that many Zimbabwean migrants in South Africa experienced severe economic impacts including unemployment, income loss and lack of access to COVID-19 relief measures. We conclude that there was a significant increase in formal, primarily digital, remittances during the pandemic and a decline in informal remittance conveyance. We highlight the need for more research in other remittance corridors to identify similarities and differences between them in terms of COVID-19 impacts and the shift from informal to formal remittances enabled by digital platforms.
