State Bond and Obligation Auctions on July 16, 2026: types, terms and who can participate

Key data

On July 16, 2026, the General Directorate of the Treasury and Financial Policy holds three Spanish public debt auctions, under the Resolution of July 10, 2026. The three references expand existing issues and are integrated into previous series, which strengthens their liquidity in the secondary market. For institutional investors, asset managers and corporate treasuries, this call opens a specific window of access to Spanish sovereign debt with returns exceeding 4% in the long segment.

What does this regulation establish?

The resolution calls three simultaneous public debt auctions of the Spanish State for July 16, 2026. Each reference has its own characteristics in terms of term, coupon and maturity:

Key operational aspects established by the resolution:

• Separable securities: the three instruments are separable (STRIPS), which allows coupons and principal to be separated for independent trading.
• Trading admission: the issued securities will be admitted to trading on AIAF Fixed Income Market from July 21, 2026.
• Exclusive second rounds: Market Makers will have exclusive access to second rounds at the resulting marginal price of each auction.
• Expansion of existing references: no new series are created, but previous issues are expanded, integrating as a single series with previous ones.

Economic and operational impact

For institutional investors and corporate treasuries, this call presents three differentiated return windows depending on the investment time horizon:

• Short segment (3 years, 2.35%): suitable for medium-term liquidity management with Spanish sovereign risk. The implicit yield from 2.3% positions it as an alternative to deposits or money market funds in a declining rate environment.
• Mid-range segment (~7 years, 3.55%): reference of balance between return and duration. Attractive for insurers and pension funds seeking medium-term liability matching.
• Long segment (30 years, 3.95%): with implicit yields that can reach 4.3%, it is the reference of greatest interest for investors with a long horizon and tolerance for price volatility. It is also the most sensitive to rate movements.

The fact that the three references expand existing series provides additional liquidity in the secondary market, which reduces the illiquidity risk for those who need to unwind positions before maturity.

Market Makers obtain a relevant competitive advantage: exclusive access to second rounds at the marginal price allows them to increase position without competing in the main auction, with known price and without award risk.

Who does it affect?

• Institutional investors: investment funds, pension funds and insurers seeking Spanish sovereign debt for their portfolios.
• Market Makers: entities with exclusive access to second rounds at the resulting marginal price.
• Corporate treasuries: companies managing liquidity surpluses and valuing the safety and liquidity of Spanish public debt.
• Asset managers and private banking: channeling sovereign debt investment for high-net-worth clients.
• Individual savers: who can access Spanish public debt through their financial institution or directly through the Public Treasury.
• CFOs and financial directors: evaluating public debt as a destination for treasury surpluses in the short, medium and long term.

Practical example

Suppose a pension fund manager decides to participate in the auction on July 16, 2026 with a purchase order for the 30-year Obligations (3.95% coupon, October 2056 maturity):

• If the award occurs at a price implying a yield of 4.3% (the upper end of the indicated range), the manager locks in that annual return until 2056 on the awarded nominal amount.
• Since the securities are separable, the manager can separate the coupons from the principal and trade them independently on AIAF from July 21, 2026, optimizing the duration management of its portfolio.
• If the manager is a Market Maker, it can also participate in the second round at the resulting marginal price, increasing position with known price and without additional competition.
• If not a Market Maker, its only participation route is the main auction on July 16.

What should investors do now?

1. Confirm the order deadline: the auction takes place on July 16, 2026. Orders must be submitted before the deadline established by each intermediary entity or directly with the Bank of Spain.
2. Select the reference appropriate to the investment horizon: evaluate whether the 3-year (2.35%), 7-year (3.55%) or 30-year (3.95%) segment fits the target duration of the portfolio and liquidity needs.
3. Verify Market Maker status: if the entity is a Market Maker, also plan participation in second rounds at the marginal price to optimize the award.
4. Prepare operations on AIAF: securities will be available for trading on AIAF Fixed Income Market from July 21, 2026. Confirm with the depositary the settlement and registration timelines.
5. Analyze separability: if the strategy includes STRIPS, coordinate with the custodian the separation of coupons and principal once admitted to trading.
