On October 6, 2026, data center real estate investment trust Digital Realty Trust, Inc. (NYSE: DLR) executed a dual-market European debt financing, closing CHF 510 million across three tranches of Swiss Franc guaranteed bonds and pricing an offering of €1.0 billion in 10-year senior guaranteed green notes due 2036. The multi-currency transactions allow the company to fund massive artificial intelligence infrastructure expansion across continental Europe while capitalizing on favorable cross-currency interest rate differentials.
The financing highlights how institutional digital infrastructure operators are managing substantial balance sheet requirements. By issuing debt in currencies where benchmark yields remain competitive relative to domestic U.S. borrowing costs, Digital Realty secures long-term fixed capital while establishing natural currency hedges for its European operating facilities.
Key Takeaways
- Dual-Currency Debt Issuance: Digital Realty closed CHF 510 million in Swiss bonds across maturities from 2029 to 2036 with coupons between 1.6803% and 2.4150%, while concurrently pricing €1.0 billion in 10-year Euro notes at a 5.125% coupon.
- Distinct Offering Statuses: The three-tranche Swiss Franc offering officially closed on October 6, 2026, whereas the €1.0 billion Euro offering was priced on October 6, 2026, with closing scheduled for October 9, 2026, subject to customary closing conditions.
- Pre-Fee Issue Pricing: The Euro notes were priced at 99.289% of par, generating an illustrative pre-fee gross issue value of €992.89 million before underwriting discounts and transaction expenses.
- Green Bond Framework: Net proceeds from both transactions are earmarked for Eligible Green Projects, with temporary interim allocations permitted to pay down revolving credit facility borrowings.
Inside Digital Realty’s Multi-Currency Debt Raise
According to a regulatory Form 8-K filed with the Securities and Exchange Commission, Digital Constellation B.V., an indirect wholly owned finance subsidiary of the operating partnership Digital Realty Trust, L.P., issued and sold CHF 510 million aggregate principal amount of senior unsecured Swiss Franc bonds on October 6, 2026. The offering was conducted outside the United States under Regulation S and within Switzerland under exemptions from the Swiss Financial Services Act.
The Swiss Franc transaction was split into three distinct tranches designed to ladder maturities across the coming decade:
- CHF 225 million of 1.6803% Guaranteed Notes due October 8, 2029.
- CHF 185 million of 2.0600% Guaranteed Notes due October 6, 2032.
- CHF 100 million of 2.4150% Guaranteed Notes due October 6, 2036.
Interest on all three Swiss tranches is payable annually in arrears. The obligations are fully and unconditionally guaranteed by Digital Realty Trust, Inc., the operating partnership Digital Realty Trust, L.P., and Digital Intrepid Holding B.V., the indirect holding subsidiary through which Digital Realty holds its Interxion European data center business.
| Tranche | Principal Amount | Coupon | Status | Maturity |
|---|---|---|---|---|
| 2029 Swiss Notes | CHF 225M | 1.6803% | Closed | Oct 8, 2029 |
| 2032 Swiss Notes | CHF 185M | 2.0600% | Closed | Oct 6, 2032 |
| 2036 Swiss Notes | CHF 100M | 2.4150% | Closed | Oct 6, 2036 |

Euro Notes Pricing and Capital Allocation Mechanics
Simultaneously on October 6, 2026, Digital Realty announced the pricing of a separate benchmark European debt transaction. Its wholly owned indirect finance subsidiary, Digital Euro Finco, LLC, priced an offering of €1 billion aggregate principal amount of 5.125% Guaranteed Notes due 2036 at an issue price of 99.289% of par.
The Euro notes carry an annual coupon of 5.125% payable annually in arrears commencing October 9, 2026, with a final maturity date of October 9, 2036. The offering is expected to close on October 9, 2026, subject to customary closing conditions. At the 99.289% issue price, the gross issue value before fees equals €992.89 million, reflecting an original issue discount of €7.11 million (0.711%). Reported net proceeds will be determined upon formal settlement after deducting underwriting commissions and estimated offering expenses.
According to the accompanying offering release furnished under Exhibit 99.1, Digital Realty intends to allocate an amount equal to the net proceeds from both the Swiss Franc and Euro notes to finance or refinance Eligible Green Projects under its Green Bond Framework. Eligible categories include energy efficiency improvements, renewable energy procurement, clean transportation, sustainable water management, and green building developments. Pending direct disbursement toward green initiatives, the company may temporarily apply proceeds to reduce outstanding borrowings under its global revolving credit facilities, fund development pipelines, or invest in short-term interest-bearing instruments consistent with REIT qualifications.
Strategic Drivers: Funding the Hyperscale AI Buildout
Digital Realty’s aggressive use of European debt markets reflects broader structural trends across global capital markets. As artificial intelligence workloads demand unprecedented data center capacity, digital infrastructure providers require billions in capital spending. Similar institutional dynamics have unfolded across private equity and alternative asset managers, including Blackstone’s Digital Infrastructure Trust and KKR and NVIDIA’s B Helix platform, both targeting scalable computing capacity.
By issuing debt denominated in Swiss Francs and Euros, Digital Realty achieves two distinct strategic benefits:
- Natural Currency Hedging: Digital Realty operates extensive colocation and interconnection campuses across Frankfurt, London, Amsterdam, Paris, and Zurich. By borrowing in EUR and CHF, the company aligns its debt service obligations with local tenant cash flows, eliminating the recurring friction and hedge rollover costs associated with cross-currency derivative contracts.
- Yield Arbitrage: In an era of elevated benchmark rates, Swiss Franc yields remain structurally lower than U.S. borrowing benchmarks, as tracked across the U.S. Treasury yield curve. Locking in Swiss coupons between 1.68% and 2.42% for 3-year to 10-year terms substantially dampens overall corporate weighted-average interest expenses.
Importantly, while these green bond issuances bolster liquidity, the company continues to manage substantial existing indebtedness across its senior unsecured notes and bank revolving credit agreements. The proceeds serve as refinancing flexibility and capex funding rather than eliminating existing balance sheet leverage.
What to Watch Next
Investors and capital markets participants should track two immediate milestones following these transactions:
- Euro Notes Settlement: Formal closing of the €1.0 billion 5.125% notes scheduled for October 9, 2026, which will confirm final net proceeds and initial balance sheet cash balances.
- Green Asset Allocation Reporting: Subsequent quarterly 10-Q disclosures outlining the specific pace of capital deployment into European hyperscale developments and revolving facility paydowns.
