ab22 February 2024Global Research and Evidence LabGlobal Rates StrategyMarch/June Treasury RollsRepo reform should boost the real money long/HF short in US and WN going forwardWith mandatory central clearing coming in 2026, we think market participants will be reluctant to do very long repo trades that extend beyond where there is clarity in the structural format of a repo trade. That means real money accounts looking to do the duration overlay trade will need to find avenues other than bond forwards, with WN and US being alternatives. WN: Sell March/Buy JuneValuation and positioning favor June.US: Sell March/Buy JuneWe think the real money long rolling forward will cause June to richen.

While mandatory central clearing of futures will not be effective until mid-2026, we think there are immediate effects. Many ALM accounts/real money accounts running against an index use a duration overlay strategy. Instead of buying an off-the-run Treasury in their index, they buy a portfolio of shorter credit and use swaps, futures, total return swaps, or bond forwards to reach their target duration/curve/bucket risk. When accounts do bond forwards, they buy a bond and finance it in term repo. They tend to want to have the term repo leg be as long as possible, because there can be P&L recognition when the repo is reset. Accordingly, 2yr or 3yr repo is typically a desired term. Unfortunately, no one knows what mandatory clearing is going to look like, because the FICC needs to make...
