25% increase in cleared swaps initial margin in the 5 days since Brexit

On Tuesday, 28th June, I posted a blog post about the impact of Brexit on OTC swaps cleared margin.

We anticipated that the impact of Brexit would progressively increase in magnitude over the subsequent days.

This post shows results from the period from 23rd to 29th June, and shows how the impact has now hit 25% for long-dated swaps change over this period. The analysis assumes the same 30Y GBP swap position as the previous post.

The impact of Brexit on your next cleared swaps margin call

With regulation driving derivatives trading firms to make decisions on their approach to mandatory OTC clearing, they will be weighing up CCPs’ competing claims about potential cost savings that can be derived from cross-margining. However, attempting to separate the hype from the reality can be difficult, while at the same time potentially significant given the possibility of up to 35% reduction on the hundreds of millions of dollars in initial margin posted by even medium sized firms.
