Leveraged US treasury Bonds

Does anyone knows how to find leverage to US Treasury bonds? we get an annual yield at least of 1%, just imagine, if you have a 100:1 leverage over 1% we are taking with almost 0 risk.

Dont want to imagine a 400:1 leverage.

but how do we get it???

If anyone can get it easily without any risk, nobody will be working in the states.

Think about this...leverage is only useful when cost of leverage is less than the return.

Return > leverage

profit = return-leverage

Most brokers offer margin at 4% (correct me if i'm wrong), you're aiming at a 1% return...

profit = 1-4

This is the opposite of arbitrage...

Also, bigger players create leverage by shorting the treasuries.
