The differences are subtle, but there are two in particular: | ||
:*[[TRS]] tend to be “[[Bullet swap|bullet]]” swaps with a scheduled termination date and do not “[[re-strike|restrike]]” their notional before maturity, and they are [[static margin|statically margined]]. | |||
:*[[Portfolio swap]]s are designed to replicate cash [[prime brokerage]]; the investor does not have a specified maturity date in mind at the outset, and may keep a swap on for a day or five years, so the broker is completely in the dark as to the likely tenor of the trade. This makes fixing an amount of margin upfront fraught. To assist with nerves in the risk department, the notional of synthetic equity [[re-strike]]s periodically (like, monthly), and [[initial margin]] is calculated daily against the ''prevailing'' “{{eqderivprov|Final Price}}” rather than the ''original'' “{{eqderivprov|Initial Price}}”. Archegos swaps were, typically, bullet swaps margined with a fixed amount up front. As they appreciated, the margin value as a proportion of their prevailing value eroded. Archegos apparently used the [[variation margin]] it was earning through those appreciating positions to double down on the same trades — ''also'' static margine — pushing the equity price further up, exacerbating the problem. His swap portfolio was a ticking time-bomb. | |||
*'''They didn’t keep an eye on the direction of the portfolio''': Archegos at first used the swap book to put on short positions that offset the long bias on its cash book. It used this bias to argue for lower margins — a request the business accommodated, provided the combined portfolio bias did not exceed 75% long or short. Over time Archegos frequently exceeded these limits, often for months at a time, but CS took no action, accepting Archegos’ promises to correct the bias. | *'''They didn’t keep an eye on the direction of the portfolio''': Archegos at first used the swap book to put on short positions that offset the long bias on its cash book.
