Despite expectations of increased T-bill supply, which typically pushes rates higher, a significant $80 billion influx of cash into money market funds is keeping repo rates unusually soft. This large volume of cash is the dominant market factor, potentially capping how high short-term funding rates can rise in the near term.
Investors are extending out of cash into low-duration bond funds, evidenced by $55 billion in inflows over five months. This shift is driven by the one-month, two-year yield curve disinverting for the first time since 2025, making it more attractive for yield-seeking investors to take on slightly more duration for a better return.
Typically, soft funding conditions provide a tailwind for widening swap spreads. However, spreads have remained unusually stagnant, moving only about one basis point. This anomaly suggests that geopolitical uncertainty or anticipation of other market events is overriding the usual funding dynamics, signaling potential for a sharp move if conditions stabilize.
Bank earnings season presents two headwinds for swap spreads. First, rising Treasury yields could cause AOCI losses, reducing banks' Treasury demand. Second, banks historically issue debt post-earnings and swap it to floating rates, an action that directly pressures spreads to narrow. This combination creates a challenging environment for swap spreads in the near term.
