Yields Hit Two-Year Highs as Companies Rush to Issue Bonds to Lock In Financing Costs
nashnova research
U.S. investment-grade corporate bond yields have topped 5.5%, a two-year high, spurring a wave of issuance as companies race to lock in rates before they climb further. Wall Street forecasts September volume near a record $215 billion, but buyer fatigue is creeping in.
Where are yields, and why the urgency?
Average investment-grade bond yields have climbed above 5.5%, the highest in over two years.
This means → borrowing is already expensive, and waiting could make it worse.
Tom Murphy, head of investment-grade credit at Columbia Threadneedle, puts it bluntly: financing planned for 2027 is being pulled forward to 2026.
In plain terms = companies would rather pay today's high rate than gamble on an even higher one tomorrow.
Will September break the issuance record?
Dealers forecast roughly $215 billion in U.S. investment-grade issuance for September; last year's record was $207.5 billion. Some banks see as much as $250 billion.
Four of the first eight months of 2026 already set monthly records, including three consecutive record-breaking months. Year-to-date supply is 7.6% above the same period in 2020.
This reflects a market-wide rush to front-load funding, not isolated one-off deals.
What role does AI-driven tech issuance play?
Tech companies raising capital for AI infrastructure are a core driver of primary-market activity. AI-related spending is projected at tens of trillions of dollars, suggesting more issuance ahead.
Bank of America strategists note, however, that several mega-cap tech firms just completed outsized deals and may pause in September.
This means → the AI bond wave comes in bursts — after a cluster of jumbo deals, expect a temporary lull.
Spreads are tight — what advantage does that give issuers?
Credit spreads — the premium corporate bonds pay over Treasuries — average below 0.8 percentage points.
Moshe Tomkiewicz, head of IG debt capital markets at Mizuho Americas, calls it a "better the devil you know" situation: rates are high, but spreads are still tight, so issuing now beats waiting for heavier supply to push valuations wider.
In plain terms = the "base price" of borrowing is up, but the "markup" is still cheap. That narrow markup is the window companies are racing to exploit.
Can buyers still absorb the supply?
Lesya Paisley, portfolio manager at Mackay Shields, says the historic issuance wave demands discipline: "be more selective and demand fair compensation."
CreditSights warns that some buyers may be approaching portfolio concentration limits — investment-grade investors typically cap a single issuer at 3%–5% of assets.
This means → even if yields are attractive, the capacity to absorb more paper is shrinking. Buyer wallets have a ceiling.
What is the core tension?
Sellers (companies) want to lock in costs and are flooding the market; buyers (investors) are tightening standards and pulling back at the margin.
Whether September actually breaks the record depends on whether these two forces stay in balance.
In plain terms = companies are pushing bonds onto the market as fast as they can, while investors are getting pickier — whoever blinks first decides whether this record falls.
