The Indian government has stopped the circulation of 500-rupee and 1,000-rupee banknotes, supposedly to combat financial crimes such as counterfeiting, corruption, money laundering and tax evasion ("India scraps 500-rupee, 1,000-rupee banknotes"; Nov 9).

I strongly support this aim, but, as a frequent business traveller, I am left wondering what to do with my old banknotes, as money changers in Singapore are not accepting the notes for exchange ("Money changers, banks stop taking old rupees"; Nov 11).

More guidance is needed on how people like me can exchange the notes.
