June levels (Exhibit 1). Pressure is not isolated to July; SPTR funding has repriced higher US Rates Research

across the curve, with quarterly expiries also reflecting a higher cost of balance sheet BofAS

(Exhibit 2). Investors are not just paying up for temporary quarter end funding but for Eleanor Xiao

BofASEquity financing spike = cash / collateral imbalance mark.cabana@bofa.com

Equity funding cost reflects a cash / collateral imbalance exacerbated by dealer frictions.

See Team Page for List of Analysts

Cash = finite amidst relatively fixed dealer balance sheets. Collateral = growing with

higher equity values & large public offerings. Dealer friction = unable to easily shift

across products or regions due to capital / other business constraints. Equity financing SPTR = S&P 500 Total Return

uses different nomenclature but the cash / collateral principles are same as US rates. FF = federal funds rate

Equity funding matters for US FI b/c it risks intermediation crowding out. If funding OI = open interest

continues higher in equities, dealers could potentially shift sheet from FI to equities.

SOFR = secured overnight financing
