Binance international

I believe it's Binance International (binance.com) as you have rightly used as your question title (0.1% fee).

If you have an SGD account, you can use your remit function in with your bank to send it to Binance. With DBS, this is known as DBS Remit. Do note that you will be subjected to bank exchange rates (which are pretty bad tbh, ~0.7%).

On Binance side, you'll have to initiate the SWIFT transfer to find the details on where to remit your money to. You can try a small amount first to test it out before sending the full sum.

Alternatively, if you have other cryptocurrencies in like BinanceSG, you can trasnfer them directly and sell them off for BUSD in Binance and trade from there as well. This can be cheaper if you're handling coins which are cheap to send like LTC or XRP, or even BNB tbh.
