I have a yen account with Citibank. 0% interest but I can transfer a couple of hundred £ a month in online and if things start hotting up dump a load more in pretty fast.
Would this work. I figured a stronger Yen is bad for Japanese stocks so didn't do it this way
What you would be doing is called going "Long" on the Yen as you think that the Yen is undervalued compared to the pound and when the pound devalues you will make some profit by selling the Yen for sterling.
What we are talking about is the "Yen carry trade". In this situation I am holding a currency pair i.e GBP/YEN and leveraging myself up say 10:1 i.e for every pound I put in get £10 pounds worth of YEN.
This is called a "Position". While this position is open you get (GBP BASE interest rate - the Yen BASE interest rate) worth of interest on it. However as it's leveraged I have to have a margin to cover this position. With a 10:1 leverage I have to have 10% of the total open position margin. So If I have £10,000 levereaged up to £100,000 then I would also need a £10,000 margin in my account.
This means for a £20,000 investment I get (GBP BASE interest rate - the Yen BASE interest rate) worth of interest on £100,000 and GBP base rate on my £10,000 margin.
Great, but there is a catch, if sterling drops below my margin, my open positions are closed and I loose my £10,000 margin. At the moment the pound is strong against the Yen and could be in for a big drop so it's up to you to weigh up the risks.
It's a very interesting subject to read up about because the amount of money generated through the Yen carry trade is so big there isn't a precise figure for it and a lot of people think that if it unwound in an uncontrolled fashion then the whole financial system could collapse.
