# Banks turn to synthetic derivatives to cut initial margin

## Options-based instruments can halve initial margin for some non-cleared products, say dealers

At least two dealers have turned to so-called synthetic derivatives to reduce the initial margin (IM) required for their interest rate and foreign exchange portfolios, with estimated margin savings of up to 50% on some positions.

New margin rules require large dealers to post initial margin against new non-cleared derivatives positions. This has created a problem for the trading of instruments such as swaptions, which are non-cleared but hedged with cleared swaps.

Under the industry’s agreed standard initial margin model (Simm), the more directional a portfolio is, the more initial margin needs to be posted, so some banks have looked to create non-cleared synthetic swaps – a long swaptions call and a short put – with the same counterparty to mimic the cleared hedge. This offsets the directionality of the swaptions position and reduces initial margin in the process.

“Swaptions have a big contribution to IM and they are delta-hedged with cleared swaps. So instead, one can use calls minus puts to reduce the IM,” says a credit valuation adjustment trader at a European bank. The trader says a 20–30% reduction will be possible by using synthetic swaps to offset IM.

Once the IM is offset, the original delta, which is the sensitivity of the position’s value to changes in the underlying, needs to be reinstated via another cleared swap. The cleared swap does require IM to be posted to the clearing house but the overall amount is less than at the start of the trade.

“We don’t want to change the overall risk profile,” says a managing director at a second European bank. “So you would take synthetic swaps created through swaptions. And then you would reinstate the risk through a swap. The swap is clearable so it will not contribute to Simm IM,” he says.

This technique is also being used for forex products, with at least one European bank using synthetic forex forwards to offset initial margin on non-cleared forex options, forex swaps and non-deliverable forex forwards (NDFs) that haven’t been backloaded to clearing. Similar to swaptions, banks use a combination of forex option puts and calls to offset the forex derivatives position with a counterparty and replace the risk with a deliverable forex forward, which is not subject to the non-cleared margin rules and so doesn’t attract IM.

“Our overall portfolio across all dealers is probably well hedged. So if we add a synthetic forward to the Simm IM portfolio, we have to reinstate the same amount of risk through different types of trade which are not subject to Simm IM. It would be deliverable forwards in this case,” says the managing director at the second European bank.

The bank has been using synthetic forex derivatives to reduce IM since the first quarter of this year. The managing director says funding costs could potentially be reduced by up to a half, depending on the initial margin profile of the portfolio being optimised.
