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.

With both the Federal Reserve and European Central Bank expected to remain on hold, forward financing rates are stable. This removes central bank policy as a key driver for the upcoming bond futures roll, elevating the importance of technical factors like investor positioning and repo market specifics.

Asset managers, who typically avoid delivery, have accumulated unprecedented net long positions in the WN futures sector. This concentration, a shift from shorter-duration sectors, is expected to unusually pressure WN calendar spreads as these positions are rolled early.

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.

German swap spread movements are being driven more by technical factors than macro fundamentals. A primary driver is the unwinding of long-end interest rate hedges by Dutch pension funds. This flow is causing significant steepening in the 10-30 year swap curve and is expected to continue.

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.

Asset managers tend to roll their futures positions early to avoid the complexities of the physical delivery period. This concentrated activity creates predictable market pressure. In sectors where these managers are net long, their early rolling can exert a bearish influence on calendar spreads.

Instead of making binary bets on whether prices will rise or fall, sophisticated traders maximize value from the "shape of the curve"—the price differentials between contract months. They shift hedges to capture these anomalies, a more nuanced approach to risk management.
