The last few days of Chinese New year holidays allowed me to spend some time on SGD INR analysis. I always had a feeling that transferring money to Indian specially with a view to play on the interest rate differential would not have been beneficial in the last year and I had to test my feeling against some actual numbers.

I took the average investable Tax Free NRE FD rate as 8% and cost of transferring money as 1%. The interest that someone could earn in Singapore was taken as average of 2% (DBS Multiplier, OCBC 360, UOB One or some money market funds) which brought the effective interest rate differential as 6% (8% – 2%).

There might be a few of you who could have got slightly better NRE FD rates and also managed a better transfer rate, however in my observation banks or transfer services usually charge anywhere between 0.8% to 1.5% as remittance fee. This fee could be charged as a out right fee or built into the exchange rate that they offer you. Similarly I took the cost of transferring money back from India as 1% as well though people tell me it can be close to 2%. I have personally never transferred money from India so just went in with the 1% charge.

The result of number crunching vindicated my gut feel  – there were only  39 days in 2015 (around 11%) which provided a better return if someone transferred money to India, invested in NRE FD and transferred it back to Singapore as compared to keeping money in Singapore and starting to transfer to India once SGD INR crossed 47.50.

Interestingly of those 39 days 12 were in Jan 2015 and remaining between 24th April to 22 May and few in mid June.

The number of days went up to 62 (around 20%) if the person decided to leave money in India instead of bringing it back but the period of transfer remained in first half of the year.

Anyone who panicked and transferred money since July would be “out of money” based on today’s DBS remittance rate of 48.50 (Market rate around 48.90).

Of-course the rates can and will change in the coming days and a few more days of 2015 might become “In the money” but I would rather transfer around 48 than at 46 – it translates to gains of around 5%.
