If you want to punt on currencies, fixed deposits are the
worst way to do it. They'll get you for 1% on the way in and 1% on the way out, and they'll pay you a below-market interest rate while you're waiting.
...no, wait, I take that back. The only thing dumber than punting on FX through fixed deposits is
keeping GBP 25,000 cash in your house.
If you want to punt on GBPSGD going up (because that's what you're doing), open an account with your friendly local FX bucketshop (I use and endorse Interactive Brokers), and press the big green BUY button next to GBPSGD. You'll get a much tighter spread, more competitive interest rates, and you won't have to worry about people breaking into your house and stealing your trade.
