21
Q

A

When a liability is uncertain, e.g. an option

22
Q

What 4 ways do clearing houses protect against risk?

A

1) Only deal with member firms
2) Require Margin
3) Use their own financial resources (e.g. credit line with a consortium of banks or have a default account
4) Insurance policies

23
Q

What is initial margin?

A

The margin required to be posted at the outset of a trade.

24
Q

What can be placed as initial margin

A

Cash or collateral (an asset with value)

25
Q

Who doesn’t need to post initial margin?

A

Buyers of options

Loss is limited to premium

26
Q

How is initial margin calculated?

A

Volatility - what is the most an asset could move in a single day

27
Q

If a clearing house determines the most a FTSE forward could move is 300 points, what is the initial margin?

A

300 * £10 = £3,000

28
Q

When is initial margin calculated.

Why does this mean that it can require topping up?

A

Calculated daily and collected each morning before the market opens.

Increased volatility means more margin may be required to be comfortable.

Intra-day margin

Members have direct debits which the clearing house will use to increase margin.

29
Q

What are spreads and how do they effect initial margin?

A

Spreads refer to having a position in the same asset or correlated assets which offset the margin required.

E.g. long July ftse future and short a September FTSE future, these positions offset and will reduce the margin

30
Q

What is an example of a spread through correlated assets?

A

Brent Crude and Oil and Gas Futures

31
Q

When else might initial margin increase?

Why is this done?

A

Approaching expiry

Reduce short term speculative pressures

Force less capitalised speculators to close out positions and reduce risk.

Ensure delivery can be made / received.

32
Q

What are the three types of margin?

A

1) Initial
2) Variation
3) Maintenance

33
Q

How is variation margin calculated?

A

Ticks Moved * Tick Price * Contracts

A

Portfolio Value / Futures Value * h

Where h is beta

37
Q

How is H calculated in the hedge ratio?

A

Volatility / Duration

Can be either portfolio or future

38
Q

What is risk that arises in a hedged portfolio called?

A

Residual Risk

Arises even in a portfolio with the corerct hedge ratio

39
Q

What are 2 examples of residual risk?

How can risk still arise?

A

1) Using the incorrect hedge ratio as a result of incorrectly assessing the beta
2) Unsystematic risk within the portfolio that the hedge cannot eliminate

Unsystematic risk can only be eliminated by further diversification

39
