What's driving the recent volatility in the global bond markets? | On Investors’ Minds - APAC Edition | J.P. Morgan Asset Management Hong Kong
Government bond markets experienced intense volatility through May 2026, driven by cautious economic outlooks while equity markets remained captivated by the AI capital expenditure (capex) story [00:00:00].
The US 10-year Treasury yield surged to a 16-month high of 4.66%, and the 30-year Treasury yield reached an 18-year high of 5.17% [00:00:40].

This upward shift was synchronized globally [00:00:53]:
German 10-year Bund yields rose to their highest levels since 2011 [00:00:53].
UK Gilts climbed to levels not seen since 2008 [00:00:53].
Japanese 30-year government bond yields reached a record high [00:01:01].
These rising yields present a direct diversification challenge for investors seeking portfolio balance against equity market gains [00:01:09].
Driver 1: The Physical Oil Shock & Geopolitical Chokepoints
Brent crude oil prices have surged 73% higher since the start of 2026 [00:01:22].
Physical supply constraints are intensifying the longer the Strait of Hormuz remains closed [00:01:27].
Long-term oil price expectations are adjusting upward: the price of Brent crude for delivery in 2026 has escalated from $68 to $88 per barrel since February 28, 2026 [00:01:33].
J.P. Morgan Asset Management expects the average oil price for the year to remain above $90 a barrel [00:01:48].
Driver 2: Aggressive Repricing of the Global Rates Outlook
Supply chain and commodity disruptions flowing from the Strait closure have forced macro markets to drastically reprice the path of global monetary policy [00:01:56].
US Federal Reserve: Expectations swung from 60 basis points of easing anticipated at the start of the year to 25 basis points of tightening priced in by year-end [00:02:04].
Global Central Banks: Markets are now pricing in 65 basis points of hikes from the European Central Bank (ECB), 48 basis points from the Bank of England (BoE), and a matching restrictive path from the Bank of Japan (BoJ) through the remainder of the year [00:02:16].
Driver 3: Structural Fiscal Concerns & Shifting Bond Ownership
Elevated government debt burdens continue to drive up the structural term premium [00:02:29].
The prospect of governments issuing further supply to offset the ongoing economic shock has brought debt sustainability back to the forefront [00:02:36].
Demand-Side Deterioration: Price-insensitive buyers are pulling back. Foreign institutional holdings of US Treasuries have steadily declined from 34% in 2015 to 24% as of April 2026 [00:02:48]. This structural exit coincides directly with an expected acceleration in net bond supply, threatening to keep yields structurally elevated [00:03:06].
Core Government Bond Strategies & Yield Curve Mechanics
The macro trajectory and whether yields pivot will depend almost entirely on the reopening of the Strait of Hormuz [00:03:20].
Yield Curve Steepening: Portfolios can hedge exposures by positioning for a steeper yield curve under two completely opposing macro scenarios [00:03:27]:
Sticky Inflation Shock: Short-term yields rise on higher policy rates, while the long end moves higher to price in structural inflation premium [00:03:33].
Growth Shock: If the inflation shock hurts growth, central banks will ease aggressively. Short-dated yields will plunge faster than long-dated yields, also steepening the curve [00:03:52].
Maturity Recommendation: Allocating deeply into long duration is premature due to persistent fiscal and inflation threats [00:08:07]. Shorter-to-medium-term maturities are highly favored, capturing attractive absolute yields while limiting drawdown exposure to further interest rate spikes [00:08:14].
Strong global corporate fundamentals have successfully compressed credit spreads across both US and European IG markets, despite macro friction [00:04:11].
The underlying surge in government benchmark rates has completely outpaced this spread compression, presenting strong entry points with excellent all-in yields for investors allocating to new paper [00:04:25].
Key Risks: Prolonged borrowing costs will eventually tighten broader financial conditions, risking corporate refinancing hurdles and weighing heavily on future corporate earnings [00:04:39]. This leaves IG exposed to sudden spread widening alongside its higher structural duration risk [00:04:52].
Credit Quality Discrimination in High Yield (HY) Markets
High Yield credit offers structural insulation against duration risk but remains exposed to downside economic growth shocks and expanding default metrics [00:05:00].
The BB-Rating Safety Play: The upper tier of high yield (BB-rated bonds) trades at a tighter yield of 6% relative to the broader high-yield index average of 8% [00:05:18]. They present a highly defensive source of carry given that impending default risks are concentrated in lower tiers [00:05:24].
Spread Dispersion: Since early March 2026, BBB, BB, and B spreads have compressed, whereas CCC spreads have widened sharply, confirming aggressive market discrimination against distressed balance sheets [00:05:37].
The Energy Sector Structure: Energy commands a 12% weighting inside the US High Yield Index (vs. only 7% in IG) [00:05:52]. Unlike prior energy default cycles triggered by collapsing demand, the current shock is supply-driven. The surviving, upgraded energy firms remaining in the index are actively benefiting from high cash-flow generation driven by supply shortages [00:06:10].
Emerging Market (EM) Debt & The Double Squeeze Risk
EM debt hard currency assets have been standout fixed income performers, pushing spreads on US dollar-denominated emerging market corporate and sovereign bonds to multi-year tights [00:06:29].
The Double Squeeze: EM faces simultaneous head-winds. Surging US benchmark yields lift global risk-free rates, while a strengthening US Dollar automatically raises the structural debt-servicing costs of USD-denominated EM liabilities [00:06:35].
Active Allocation Filter: Managers must strictly avoid nations and corporates highly exposed to input energy crises while shifting allocations to EM countries benefiting directly from the massive AI-related capex waves [00:06:48].
Securitized Products as a Floating Rate Macro Hedge
Securitized asset classes have experienced strong spread tightening despite the sovereign yield rout, backed by resilient underlying collateral quality [00:07:01].
Floating Rate Structural Advantage: Floating rate assets offer an explicit, direct hedge against a sticky "higher for longer" inflation or policy rate regime [00:07:19]. Highly elevated base rates continue to lock in very attractive all-in yields, driving robust institutional investor demand [00:07:27].
Risk Warning: Selectivity is critical. Lower-rated tranches across securitized structures maintain high correlation to consumer or commercial slowdowns should this macro inflation wave trigger a broad credit event [00:07:35].
