SETTLEMENT |
|---|
Clearing Broker | ||
|---|---|---|
An organization that acts as an intermediary wishing to trade on an Exchange Detail A Clearing Broker acts for an organization in two capacities: Intermediary between a trading organization and the Exchange's Clearing House - trades are executed directly with the Exchange itself Intermediary between a trading organization and an Exchange to allow trading with that Exchange without being a member | ||
Clearing House | ||
|---|---|---|
An organization that manages the clearing for an Exchange Detail Every Exchange appoints a Clearing House to manage the clearing of trades executed on the Exchange Bigger Exchanges may own their own Clearing House - others may appoint a large Clearing House to act for them For most settlement and financial purposes the Clearing House (or a Clearing Broker acting for us) is the settlement and financial counterparty to futures, swaps and spot trades executed on the Exchange | ||
Close out | ||
|---|---|---|
Flattening an open position to a net zero (or flat) position Detail Trading activity in general leads to opening positions, and very often to closing out those positions before the delivery period For example I may sell 10,000 therms of gas for delivery May 2024 today I have an open position of 10,000 therms in 2024 Next year the price has dropped and I decide to buy back all 10,000 therms at the lower price, thus locking in a profit (sell price - buy price) x 10,000 remember when we short a position we make a profit when the price drops! I have no remaining open position in 2024 gas - so I have closed out my position I can always re-open it by executing another trade If my second trade had been to buy 6,000 therms then I would have closed out 6,000 therms, and have 4,000 therms remaining open position Closing out a Futures position on an Exchange has an additional meaning and consequence The profit or loss value would immediately be considered as realized P&L for the following reasons:

Confirmation | ||
|---|---|---|
A Confirmation is a document describing a trade that has been executed, and is generally sent by the Seller to the Buyer to check the trade details, to be returned by the Buyer confirming that the trade details match the trade as they have recorded it The Confirmation, or Confirm, process allows both parties to agree the trade details Detail The Confirmation process, and the form of the Confirmation document are defined in the Master Agreement, usually as an Appendix The Confirmation match is the final stage of the contract between the two parties, without it the trade is not legally binding, as well as specifying the trade details the Confirmation also specified the Master Agreement under which the trade was executed Confirmations are not normally produced for Exchange trades Some parties produce and send Confirmations for both Buy and Sell trades Confirmations must be signed by an authorized signatory in the Trading Organization Confirmations are normally produced and signed electronically Matching Confirms tends to be a manual process - systems of bar coding have been proposed There are schemes that electronically confirm trades, generically known as ECM (Electronic Confirmation Matching) These are generally point to point - but there is no reason not to utilize a centralized matching service | ||
Fee | ||
|---|---|---|
A fee is a cash payment which may be associated with:
Detail Fees are usually cash payments that are not directly related to delivery of a commodity There are four general categories of fees:
Fees booked against trades are generally associated with a cash flow type, so that they can be correctly allocated in P&L, invoicing and general ledger accounting | ||
Floating | ||
|---|---|---|
A financial side or leg of a trade that is not fixed in advance, but is dependent on the value of some observable (usually an index) at a pre-agreed time related to the delivery date Detail Most trades involve at least two legs or sides, in a straightforward physical Forward contract one side is the physical delivery of the commodity, the other is the cash payment in settlement of the commodity delivered In an indexed forward, or floating forward, the cash side is not fixed in advance, but related to an index (usually published daily), and generally fixed in daily or monthly either at the daily price or the average of the daily-published monthly price | ||
Index | ||
|---|---|---|
An Index is a set of prices that are published for a commodity or product, usually derived from trading data, using an open and independent method Detail An index consists of a set of time periods, with an associated price (or set of prices) for a particular commodity or product for each of the time periods: The time periods are sometimes called grid points (or gridpoints) A typical index has daily granularity forward from the date it is published for a number of days, then monthly for some months, then quarterly, seasonal and annual For each time period there may be a bid price, an offer price, and an average (mean) price Indexes are usually published at the end of each trading day, and represent some sort of average of the prices that Forward and Futures contracts actually traded at on that day (or for a pre-defined period of the day) Various organizations publish indexes for different commodities and products: Exchanges publish indexes for the various products they offer Independent analysts publish indexes for commodities in markets they specialize Trading organizations use indexes to: Derive forward (valuation) curves Fix in floating prices of floating price trades Agree forward valuation of trade portfolios with counterparties for netting agreements There is some similarity between indexes and curves since they are both sets of time-series data. The main differences are: Indexes are published by independent organizations, and are available to any organization that wishes to subscribe to them Indexes only relate to prices of commodities and products Curves are usually created by, and proprietary to, the trading organizations that create them Curves consist of any time-series data, including valuation, volatility, interest rates etc.

Invoicing | ||
|---|---|---|
Like most businesses, we sell something, we deliver it, we raise an invoice, we send it to our buyer, we get paid - we hope. The Master Agreement between us and our counterparty will specify if we raise an invoice for a specific delivery (of oil for example), or for a continuously delivered commodity (gas or power for example) over a period (usually a day, week or month) Detail The two main invoicing schedules are:
Invoices usually have the following granularity:
We may therefore raise a number of invoices for a counterparty, with different combinations of the above Once we generate, or raise, an invoice, and are satisfied that it is correct, we transmit the invoice(s) to our counterparty, and we post the invoice(s) into an Account in our General Ledger We expect our counterparty to be doing the same for commodities that we have bought from them, and expect to receive invoice(s) that we will check against our own records To help this we raise a set of shadow invoices, or purchase orders, so that we can compare these to the invoices received from our counterparty. Once agreed we post these purchase orders into an Account in our General Ledger | ||
Margining | ||
|---|---|---|
Margining is a form of Settlement, whereby exposure to Credit Risk between two parties is limited by keeping the overall Credit Exposure below a certain threshold by means of Margin payments between the parties whenever the threshold is breached Detail Let's take a simple example
If you go out of business or default on the deal I won't lose out
But if I default then you will lose $200
I need to arrange for that $200 available to you in case I do default
On day three we both note that the price has risen to $62 per tonne - that's good for me, bad for you Now if I default you won't need to deliver $12,400 worth of coal in exchange for $12,000 cash
But if you default then I'll be $400 worse off
You need to arrange for $400 to be available to me in case of default
Let's say on day eight the price rises to $66 per tonne
You now need to arrange for $1,200 to be available to me in case of default
We talked about making the cash available in case of default - how does that work?
There are actually a few different schemes:
Clearingin a clearing arrangement each if us has a margining account with a central clearing house
Before we even start trading we need to deposit some money into the account, and each time we execute a trade we need to make sure there is sufficient in the account to cover a certain amount of loss
Let's say we both deposit $1,500 initially and then an additional $1,000 as a result of doing the single trade - we can see that on typical price movement, for the volume of the trade this, then it would take quite a large movement in the price to change the value of the trade by $1,000
We both now have $2,500 deposited
The initial $1,000 deposit against this specific trade is called the Initial Margin
At the end of day two the clearing house would remove $200 from my account and put it into your account - this is the Daily Variation Margin
I now have $2,300 and you have $2,700
At the end of day three the clearing house would remove $600 from your account and put it into my account - this is the Variation Margin
I now have $2,900 and you have $2,100
At the end of day eight I would have $3,700 and you have $1,300
At this stage you would need to make a payment into your account to top it back up to a minimum level - this may be $200, or it might be more depending on the agreement
CollateralWe might agree to post $2,000 collateral with each other to cover any initial movement either way
We agree to margin limits of a minimum of $1,500 and a maximum of $2,500, if the margin falls below $1,500 we will post a minimum of $500 to get the collateral back up to $1,500, and likewise, if the collateral goes above $2,500 we will be able to withdraw cash to bring it below $2,500
At the end of day two my collateral stands at $1,800 - the cash in the collateral account minus the $200 current liability on the deal at that point - we're both OK, I have more than the minimum $1,500
At the end of day three I have $2,400 collateral and you have $1,600 (your original $2,000 less your current liability of $400 on the deal)
At the end of day eight I have $3,200 collateral, and you have just $800 (your original $2,000 less your current liability of $1,200 on the deal)
A requirement to top up a clearing account or collateral account is known as a margin call

Master Agreement | ||
|---|---|---|
When two parties execute a trade between themselves they specify the terms of the trade: Price, Volume, Location, timing etc. But in order to successfully manage the trade's delivery and settlement a lot more information needs to be available than is captured in the trade details, such as when payment is due, who needs to notify a TSO etc. This additional detail is held in a Master Agreement Each trade that is executed is regulated by a Master Agreement Detail Master Agreements exist to cover various sorts of trade, for example the UK standard gas and power Master Agreements : GTMA (Grid Trading Master Agreement) covers UK power trading, complete with all the details of notification NBP97 (Short Term Flat NBP Trading Terms and Conditions Ref. NBP 1997) covers natural gas trading at the NBP complete with details of nomination Master Agreements may reference other Master Agreements - ISDA for example is an organization that is aiming to offer master agreements that unify trading, for example at the NBP and at TTF Master Agreements are themselves referenced by bilateral trading agreements, which are agreements set up by pairs of potential trading partners to specify which Master Agreements will be used for different products and instruments, and usually cover other arrangements such as netting, collateral etc. Master Agreements may have schedules or annexes that define additional terms, or override terms in the main agreement Bilateral Master Agreements may have additional schedules that define variations to the standardized master agreements A Confirmation, as well as confirming the trade details, also confirms the master agreements that regulate the trade, and may itself contain exceptions or variations from the general bilateral terms
