Treasury rout opens switch-option trade for arbitrage-focused traders
A prolonged selloff in US Treasuries is creating a potential opportunity for hedge funds and other relative-value traders to exploit pricing discrepancies between Treasury futures and the underlying bonds, according to a report by Bloomberg.
A recent surge in US Treasury yields has opened up an intriguing trading opportunity for sophisticated investors, according to Bloomberg. The prolonged decline in Treasury prices has pushed long-dated yields above 5%, the highest level in nearly two decades. This heightened volatility is giving rise to a new type of Treasury arbitrage known as the "switch option" trade.
Traditionally, traders exploit pricing discrepancies between Treasury futures and the actual bonds by shorting futures contracts while simultaneously buying the cheapest-to-deliver (CTD) bond. However, as Treasury yields rise sharply, the bond designated as the CTD can change. Savvy traders with short futures positions can then quickly switch into the newly designated CTD bond, potentially capturing the resulting price differential.
The switch option trade is becoming increasingly relevant due to several factors. The looming issuance of corporate bonds and long-dated inflation-protected securities this week, along with a 20-year Treasury auction, have contributed to the steep rise in 30-year yields, reaching their highest point since 2007. Bloomberg's analysis suggests that a modest 10 basis-point increase in long-term yields could prompt a shift in the CTD bond, moving from the current August 2045 issue to the February 2046 offering.
A more significant 30 basis-point rise could propel the CTD further down the delivery basket, to the August 2049 bond.
Barclays strategists Andres Mok and Amrut Nashikkar have emphasized the growing importance of this switch risk, particularly as long-end yields surpass the 5% threshold. They note that a large-scale sell-off of Treasuries could push the CTD further out along the eligible bond basket, while a sustained rally in Treasuries could have the opposite effect.
However, implementing this strategy is not without its challenges. Transaction costs and the timing of switches can quickly diminish potential returns. Moreover, changes in the CTD bond require futures traders to adjust their hedge ratios, which may entail additional buying or selling of contracts and could introduce further market volatility.
Despite these risks, the combination of elevated yields, uncertainty surrounding the Federal Reserve's policy outlook, and renewed pressure from higher oil prices has created a more favorable environment for relative-value strategies in the Treasury market.
