Global corporate bond issuance surged past the $2 trillion mark in the first half of 2026, setting a new record for the period as chief financial officers moved aggressively to secure funding ahead of anticipated central bank rate decisions, according to data released Monday by Refinitiv.
The figure represents a 22% increase on the same period in 2025 and marks the busiest six months for corporate debt markets since the pandemic-era borrowing spree of 2020. Investment-grade issuers accounted for $1.6 trillion of the total, with the remaining $400 billion coming from high-yield borrowers.
The technology and healthcare sectors led the charge, together accounting for nearly 40% of all issuance, as firms sought to fund capital expenditure programmes, refinance maturing debt, and build cash buffers. “CFOs are reading the same tea leaves as everyone else,” said Rebecca Chen, head of fixed income strategy at Barclays. “With inflation proving stickier than expected in several major economies, there’s a growing consensus that the rate-cutting cycle may be shallower and later than markets priced in six months ago. The smart money is locking in term funding now.”
European issuance proved particularly robust, rising 31% year-on-year, driven by a wave of sustainability-linked bonds and a resurgence in merger and acquisition financing. In the United States, volumes climbed 18%, supported by strong demand from pension funds and insurance companies seeking to lock in yields above 5% on investment-grade paper.
Spreads have tightened markedly across the credit spectrum. Investment-grade spreads narrowed to an average of 85 basis points over benchmark government bonds, down from 105 basis points at the start of the year, reflecting voracious investor appetite for corporate credit. “The sheer weight of money chasing these deals is remarkable,” Chen noted. “Recent investment-grade offerings have been oversubscribed by an average of 4.2 times.”
However, analysts caution that the issuance boom carries forward-looking risks. The International Monetary Fund warned in its June Global Financial Stability Report that elevated corporate leverage in certain sectors — particularly commercial real estate and highly-indebted technology firms — could amplify stress if economic conditions deteriorate. Total outstanding global corporate debt now stands at approximately $84 trillion.
Looking to the second half, market participants expect issuance to moderate as the summer lull takes hold and borrowers who front-loaded their funding needs step back. “We’ll likely see a quieter third quarter, followed by a fourth-quarter rush if the rate outlook firms up,” Chen said. “The key variable is inflation data over the next two to three months. If it surprises to the downside, the window for issuing at these yields narrows considerably.”
