Bank issuance effect on swap spreads

Barclays | Interest Rate Derivatives

• Broader market factors including risk appetite, funding conditions, dealer balance sheet

capacity and Treasury supply dynamics remain the primary drivers of swap spreads.

Issuance-related hedging flows matter, but at the margin.

• US regulators have proposed reducing capital requirements for US GSIBs (B3E and GSIB

surcharges) in addition to those that have been approved (SLR). This should reduce minimum

requirements for regulatory issuance (ie, TLAC and LTD) if the proposals are finalized as is.

Bank issuance and swap spreads

With Q2 earnings season kicking off this month, we have been getting questions about the

performance of swap spreads around banks' issuance windows. As banks exit blackout periods,

they access debt capital markets, raising cash for funding, refinancing and regulatory needs.

Bank issuance tends to exert tightening pressure on swap spreads,particularly in the belly/

intermediate sector (5-10y) as issuers swap newly issued fixed-rate debt into floating by

receiving in swaps to manage their asset/liability duration exposure. In a steep yield curve

environment, banks prefer to fund short-term and borrow long-term, which boosts net interest

margin (NIM). Investor demand is typically stronger for fixed-rate debt, where banks can get

better liquidity and execution, and then swap the proceeds to floating-rate debt.

In the post-COVID period, there has been a modest spread-tightening bias heading into earnings

season. While issuance-related hedging flows matter, they are secondary to broader

drivers such as risk appetite, funding conditions, dealer balance sheet constraints and

Treasury supply dynamics.
