While funding rates are the main driver for many Eurex futures rolls, the Bund and Shats calendar spreads are different. Their performance is primarily determined by the evolution of the cheapest-to-deliver (CTD) yield curve and relative value dynamics, making them directional to yields.

Contrary to historical norms where Eurex futures lack delivery option value, the German Buxl (30-year) future currently presents some. This is driven by potential Cheapest-to-Deliver (CTD) switches, particularly to a lower coupon bond in a sell-off, creating an asymmetric upside risk for the delivery option's value.

With the European Central Bank firmly on hold, a low-volatility regime is expected to persist. However, the options market is not fully pricing in the potential for directional curve movements, such as steepening or flattening. This creates opportunities to express curve views through options where the risk is undervalued.

Despite negative political headlines, the Euro/Dollar spot rate has fallen below its fair value of 1.17, as determined by real yield differentials. This marks a significant shift, suggesting the risk/reward is once again becoming attractive for medium-term bulls on the currency.

Despite a recent sell-off, German Bunds are seen as attractively valued compared to US Treasuries. The US-Germany spread is considered too tight, with US yields approximately 7 basis points too expensive versus their Euro counterparts, presenting a cross-market opportunity for fixed income investors to favor German debt.

The sell-off in 30-year German yields has increased the probability of the Buxel futures' 'Cheapest to Deliver' (CTD) bond switching. This is not a trivial event; such a switch would alter the future's price sensitivity (delta) by approximately 35%, posing a significant and potentially unmanaged risk for investors who are not dynamically hedging their positions.

Germany's finance agency signaled it would adjust debt issuance in response to a steepening yield curve. This sensitivity acts as a structural anchor on intermediate-term yields, creating a potential outperformance opportunity for German bonds versus US and UK debt, which face greater fiscal pressures.

Lacking official CFTC-style data, analysts estimate Eurex futures positioning using open interest and price changes. This proprietary analysis reveals significant long positions in Italian BTP and German Schatz futures, corroborating client survey data that shows the European carry trade is a popular theme.

A switch in the cheapest-to-deliver (CTD) bond for Eurex Buxel futures could cause a massive 35% change in the contract's DV01 (a measure of interest rate risk). This presents a significant hedging risk for investors who are not dynamically managing their exposure, as the duration gap between the current and competing CTD bonds is exceptionally large.
