Morgan Stanley IM: Hyperscalers' Euro Bond Issuance to Erode Eurozone Credit Appeal
Claire Weston
Morgan Stanley Investment Management warns that if hyperscalers shift more bond issuance to Europe, the valuation edge of euro-zone investment-grade credit over the US will shrink — undermining the core logic behind a 'buy Europe, sell US' credit strategy.
Why does Morgan Stanley IM favour euro-zone IG credit?
Senior strategist Hugh Briscoe notes that hyperscalers — tech giants such as Google and Amazon that build massive data centres — have funnelled the vast majority of their AI-infrastructure bond issuance into the US investment-grade market.
This means → the US market absorbs far more supply pressure than Europe, pushing US spreads wider and making euro-zone IG look relatively attractive.
In plain terms = the US market is flooded with new bonds, so prices drop; Europe stays dry, so prices hold — that gap is why Morgan Stanley prefers Europe.
How could this advantage disappear?
Briscoe warns that if hyperscaler issuance in Europe rises significantly relative to the US, the euro zone's valuation edge will narrow.
The key word is "relatively" — even if Europe's total issuance stays below America's, a faster rate of increase is enough to close the gap.
This reflects a deeper signal: euro-zone credit appeal is not about Europe's own strength — it rests on the comparison that "the US hurts more."
Have hyperscalers already started issuing in Europe?
This year Google completed debut bond sales in sterling and Swiss francs, both among the largest-ever deals in those currencies, and simultaneously tapped the euro bond market.
Briscoe sees the motive clearly: "Funding costs in the US are elevated; they are looking for alternative sources." He expects the shift to become more systematic.
This means → European issuance is not a one-off experiment — the continent's "supply-light" status is being eroded.
How severe is the supply pressure in the US?
Bloomberg data show US hyperscaler bond issuance this year has topped $132 billion, driving overall primary-market volume up 31% year-on-year.
July spreads widened across the board: Meta bonds widened ~22 bp on average; Oracle ~29 bp. When Amazon printed a $25 billion deal last month, traders sold existing bonds to make room, intensifying secondary-market pressure.
In plain terms = too many new bonds, not enough buyer appetite — investors had to mark down existing holdings to absorb the fresh supply. That is what a supply shock looks like in practice.
Can hyperscaler fundamentals support this borrowing?
Briscoe is relatively upbeat on fundamentals: most hyperscalers still have strong balance sheets, and their borrowing costs remain low relative to their credit ratings.
But the real question, he stresses, is "what return the invested capital will generate" — the money is raised; whether AI spending pays off is what matters.
He judges that this year's credit-market returns come mainly from coupon income, not spread tightening, and that heavy supply will "push IG spreads wider by year-end."
How much more supply is coming?
Alphabet, Meta, Microsoft, and Amazon have collectively committed roughly $2.4 trillion in capital expenditure over the coming years.
This means → bond-market supply pressure will persist — this is not a one-quarter event but a multi-year cycle.
Whether Europe can absorb its share of that supply without damaging valuations will be the critical test of euro-zone credit attractiveness.
