Upper bound on forward settlement price발음듣기

Let's see if there's a way to make a risk-free profit.발음듣기

And let me just tell you right from the get-go there's usually not that many way to make risk-free profit in the world, so this is very theoretical.발음듣기

If the spot price for gold was a thousand dollars...발음듣기

So the spot price literally just means the market price.발음듣기

If you were to buy or sell gold today and actually exchange hands, then you would pay or sell the gold for a thousand dollars per ounce.발음듣기

And let's also say that the 1-year forward settlement price is $1200 per ounce.발음듣기

So if you want to buy gold one year from now, you can agree right now to buy it for $1200.발음듣기

Or if you want to sell gold one year from now, you could agree right now to sell for $1200 by entering into a forward or futures contract.발음듣기

And just, the other details, the interest rate to borrow money is 10%.발음듣기

And the carrying cost of gold is $50 per ounce per year.발음듣기

And the carrying cost means if I had an ounce of gold, and I wanted to hold it responsibly, I wanted to store it, maybe someplace in a safe at a bank, and I wanted to insure it in case it got stolen or in case someone lost it, that would cost me $50 per ounce per year.발음듣기

So that's what we mean by carrying cost.발음듣기

And let's say you could also invest money risk-free in this type of a market...발음듣기

(I've just made up these numbers) for 5% a year.발음듣기

So how could you make the money?발음듣기

Well, you could, and we're assuming you start with nothing, so you could literally just borrow $1000.발음듣기

And then you use that to buy an ounce of gold in the spot market.발음듣기

So you buy one ounce of gold.발음듣기

And you also agree to sell it in the future.발음듣기

So you enter into that forward contract.발음듣기

So you enter into forward as the seller.발음듣기

So you are, on the spot market, you are the buyer.발음듣기

And on the forward market, one year from now, you agree to be the seller.발음듣기

So let's just think about how this is going to play out.발음듣기

So over the course of the year, you will have some cost.발음듣기

You will have to pay the interest on this $1000. That's 10%.발음듣기

So you're going to have to pay $100 in interest.발음듣기

And you're going to have to pay the carrying costs.발음듣기

$50 per ounce. So, $50 carrying cost. And so, when we end up a year from now, you can sell, you will sell the gold for $1200.발음듣기

One year from now. And you know you can do that, because you entered into the forward agreement.발음듣기

And then you can pay back the $1000 loan plus $100 interest.발음듣기

And let's say you had to pay the carrying cost at the end of the year to the bank.발음듣기

So plus the $50 carrying cost.발음듣기

So how much did we profit?발음듣기

Well, we get $1200 and we had to pay back $1150.발음듣기

So we make... So, $1200 minus $1000 minus $100 minus $50...발음듣기

We make a profit of $50.발음듣기

So the big takeaway here is... that these type of things here normally don't exist!발음듣기

If they did, people would do it all day and all night.발음듣기

And this price would go up because everyone would want to buy on spot... and this price would go down because everyone would want to sell on the futures market.발음듣기

Everyone would want to do this right here.발음듣기

So the appropriate price is this one should not... this price, based on these numbers right here, should not be any higher than $1150.발음듣기

So the correct market price here, if we didn't want risk-free profit, or essentially what the arbitragers would make happen by kind of taking advantage of this... it would eventually go to $1150.발음듣기

So it's essentially the spot price, plus the cost to borrow money at that spot price, plus the carrying cost.발음듣기

So that's essentially what would be the rational price for the futures contract, Or the forward settlement price.발음듣기
