Duration & Credit Pulse

Week Ending June 29, 2025

Executive Summary

Bottom Line: The Israel-Iran conflict that erupted with US strikes on June 22 delivered the most significant geopolitical shock to fixed income markets in years, yet credit spreads barely budged from historic tights even as Treasury yields whipsawed on competing safe-haven and inflation narratives. The successful June 24 ceasefire triggered oil's sharpest single-day decline (-7.2%) since 2020, driving a decisive bull steepening in Treasuries with 2-year yields plunging 16 basis points while high yield spreads compressed to just 282bp—the 24th percentile of their 5-year range—highlighting dangerous complacency amid valuation extremes.

Curve Analysis: Treasury markets delivered a textbook bull steepening as geopolitical tensions resolved, with the 2s30s spread widening from 98 basis points to 109bp. The front-end led the rally with 2-year yields falling 16bp versus just 5bp for the 30-year, as traders unwound crisis hedges following the June 24 ceasefire announcement. Long bonds showed more modest gains despite their extreme 92nd percentile positioning, suggesting persistent term premium demands. The move reflected both an unwind of inflation premiums built during the conflict's escalation and renewed confidence that the Fed could maintain its patient stance without addressing supply-shock inflation.

The week's dramatic geopolitical developments—beginning with US strikes on Iranian nuclear facilities on June 22 and concluding with a negotiated ceasefire on June 24—created extraordinary volatility that ultimately resolved in favor of duration bulls. The Israel-Iran conflict Treasury yields initially spiked on inflation fears as oil touched $78.50, but the swift diplomatic resolution triggered a flight from commodities into bonds. The 2-year yield's 16 basis point plunge marked its largest weekly decline since March, signaling market confidence that Middle East tensions would not derail the Fed's measured approach.

Oil's Historic 72-Hour Round Trip: WTI crude's violent journey from $68.00 to $78.50 and back to $68.51 in just three trading sessions epitomized modern geopolitical risk pricing. The June 24 collapse of 7.2%—the largest single-day decline since April 2020's negative pricing episode—completely erased the inflation premium that had been building since early June. Energy equities (XLE) fell 4.2% for the week despite the crisis resolution, suggesting permanent demand destruction fears. This commodity whipsaw left CTAs and macro funds nursing estimated losses exceeding $2.8 billion while validating the Fed's view that supply shocks remain transitory.
Ceasefire Changes Everything: The June 24 ceasefire announcement at 04:00 GMT marked an inflection point that reverberated across global fixed income markets. Within hours, WTI crude crashed 7.2% in its steepest single-session decline since April 2020, while Treasury yields collapsed as inflation premiums evaporated. The speed of the reversal—from crisis to resolution in just 48 hours—highlighted how geopolitical risk premiums had become exaggerated. More concerning was the immediate return of risk appetite, with credit spreads tightening even as the 30-year Treasury remained at its 92nd percentile, suggesting investors learned little from the near-miss with a broader regional conflict.

Credit Pulse

MetricJune 22, 2025June 29, 2025Weekly Δ5-Year Percentile
IG OAS 81 bp 80 bp -1 bp 33rd %ile (middle range)
HY OAS 292 bp 282 bp -10 bp 24th %ile (low)
VIX Index 20.62 16.32 -4.30 31st %ile (middle range)

Credit markets exhibited remarkable resilience during the week's geopolitical turmoil, with high yield spreads tightening 10 basis points to 282bp despite the most significant military escalation in the Middle East since 2003. This compression to the 24th percentile of the 5-year range occurred even as initial reports suggested potential oil supply disruptions that could cripple energy-sensitive sectors. Investment grade spreads barely moved, edging 1bp tighter to 80bp, maintaining their position in the middle of historical ranges despite extreme Treasury volatility.

The credit market's sanguine reaction becomes more perplexing given Moody's historic May 16 downgrade of US sovereign debt from Aaa to Aa1, completing the unprecedented loss of America's AAA rating from all three major agencies. Rather than widening to reflect heightened sovereign risk, spreads have compressed further, with foreign investors providing $109 billion of demand year-to-date despite April TIC data showing $50.6 billion in net Treasury selling. This divergence—foreign investors fleeing government bonds while embracing corporate credit—suggests a troubling reordering of perceived risk hierarchies that could violently reverse during the next crisis.

Spreads Ignore Geopolitical Reality: The 10bp tightening in high yield spreads during a week featuring US military strikes on Iran reveals dangerous market complacency. At 282bp, high yield compensation sits at just the 24th percentile while 30-year Treasuries trade at the 92nd percentile—a historic divergence suggesting credit investors have abandoned risk discipline. The VIX collapse from 20.62 to 16.32 following the ceasefire implies markets believe all risks have passed, yet the fundamental tensions that triggered the conflict remain unresolved. This combination of tight spreads, collapsed volatility, and extreme Treasury yields creates asymmetric risk toward sudden spread widening should geopolitical tensions resurface.

US Macroeconomic Assessment – Geopolitical Shock Tests Market Resilience

The week of June 22-29 will be remembered as a defining moment when US foreign policy directly intersected with financial markets, as President Trump's decision to launch strikes on Iranian nuclear facilities at Fordow, Natanz, and Isfahan on June 22 represented the most significant American military action in the Middle East in over two decades. The 48-hour period between strike authorization and ceasefire negotiation compressed years of geopolitical risk premium building and unwinding into a single devastating week for volatility traders.

Oil markets delivered the week's most dramatic price action: WTI crude's journey from $68 to $78.50 and back to $68.51 in just three trading sessions epitomized the whipsaw nature of modern geopolitical risk. The 7.2% single-day collapse on June 24 following ceasefire announcements ranked among the commodity's sharpest declines in history, erasing inflation premiums that had been building since early June. This violent round trip left energy traders nursing significant losses while highlighting the fragility of supply-shock inflation narratives that had dominated Fed discussions.

Limited economic data left markets focused on sentiment indicators: With no major data releases during the June 22-29 week, traders parsed consumer confidence measures for signs of geopolitical impact. The Conference Board's index plummeting to 93.0 on June 24—down from May's 98.4—suggested households immediately recognized the gravity of military escalation. Yet the University of Michigan's sentiment improvement to 60.7 by week's end indicated rapid stabilization following the ceasefire, though readings remained 18% below December 2024 levels as tariff concerns persisted.

Fiscal Revolution – Tariffs Deliver 1934 Redux: June's stunning $27 billion budget surplus, driven by an 18.2% effective tariff rate—the highest since the Smoot-Hawley era—fundamentally challenged deficit narratives. Customs duties generated $27 billion in a single month, compared to just $85 billion for all of fiscal 2024. While this windfall temporarily reduced Treasury issuance needs, dropping Q2 borrowing estimates by $85 billion, sustainability remains dubious. The Congressional Budget Office estimates each percentage point of tariffs reduces GDP growth by 0.1%, suggesting June's revenue surge came at substantial economic cost. Markets struggled to price whether this represents a new fiscal paradigm or a one-time sugar high before inevitable retaliation and recession.

Market positioning reflected conflicting narratives: Despite the week's extraordinary volatility, institutional flows suggested more concern about missing upside than protecting downside. High yield funds received $1.8 billion in the week's final two days, while Treasury funds saw modest outflows of $450 million. This risk-on tilt, even amid military strikes and oil spikes, highlighted the market's muscle memory from a decade of buying every dip. The contrarian indicator: retail investors pulled $2.3 billion from equity funds during the week, typically a bullish signal for risk assets.

Federal Reserve Policy Outlook – Patience Tested But Maintained

The Federal Reserve entered its traditional summer quiet period at precisely the wrong moment, with the June 17-18 FOMC meeting occurring just days before geopolitical chaos erupted. The Committee's decision to maintain rates at 4.25-4.50% for a fourth consecutive meeting while signaling potential September easing now appeared prescient, providing markets with a steady anchor during the week's turmoil. The absence of Fed communication during the crisis itself—no emergency statements or official commentary—reinforced the institution's commitment to data dependence over market volatility.

Markets maintained conviction that geopolitical shocks wouldn't alter the Fed's trajectory, with September rate cut probability holding steady near 75% throughout the week's drama. This stability reflected growing consensus that supply-side inflation shocks from oil or geopolitics fall outside the Fed's reaction function unless they become embedded in expectations. The rapid resolution of the Iran crisis validated this patient approach, though questions lingered about whether repeated geopolitical flare-ups might eventually force a policy response. The week's events highlighted the delicate balance between maintaining credibility through consistency and responding to genuine economic threats.

Yet beneath this surface calm, structural pressures continued building. April's Treasury International Capital (TIC) data revealed foreign holders sold $50.6 billion in US government securities, with China's holdings falling below $770 billion for the first time since 2009. Japan, traditionally the most reliable buyer, reduced holdings for a third consecutive month. This foreign retreat helps explain why 30-year yields remain at the 92nd percentile despite Fed pause expectations—without the traditional bid from overseas central banks, term premiums must rise to attract domestic buyers. The June geopolitical shock likely accelerated this trend, though confirmation awaits July's TIC release.

Week Ahead: Focus Returns to Fundamentals

  • FOMC Minutes (July 2): June 17-18 meeting minutes gain extra scrutiny for any discussion of geopolitical risks or oil price impacts on inflation outlook. Markets will parse for hawkish dissents given the subsequent Iran crisis.
  • Employment Report (July 3): June payrolls could show hiring hesitation during Iran crisis week. ADP's Wednesday preview and official Friday data will reveal if geopolitical uncertainty froze hiring decisions.
  • ISM Manufacturing PMI (July 1): June's reading takes on heightened importance as first clean look at real economy impact from both tariffs and geopolitical tensions. Consensus expects 49.2.

Israel-Iran Conflict Impact on Fixed Income Positioning

The week's geopolitical shock and rapid resolution offers crucial lessons for fixed income positioning in an era of heightened tail risks. The Israel-Iran conflict's impact on Treasury yields—initial spike on supply fears followed by aggressive rally on resolution—demonstrated that duration remains the superior hedge for geopolitical uncertainty, despite inflation concerns. Credit's muted response, with spreads actually tightening through the crisis, revealed dangerous complacency that leaves little cushion for the next shock.

The persistence of valuation extremes despite the week's drama suggests structural forces dominate tactical considerations. The 30-year Treasury's 92nd percentile positioning barely budged despite wild intraweek swings, while high yield spreads at the 24th percentile seem to price perfection in an obviously imperfect world. This divergence between rates and credit creates opportunities for relative value trades, particularly curve steepeners funded by credit spread wideners. The VIX collapse to 16.32 offers cheap tail hedges for those believing geopolitical risks merely paused rather than passed.

For institutional allocators, the week reinforced the importance of liquidity over yield in uncertain times. The Treasury market's ability to absorb massive flows during both the crisis escalation and resolution, while credit markets saw sporadic liquidity gaps, argued for maintaining government bond overweights despite richer valuations. The successful navigation of this geopolitical storm shouldn't breed complacency—rather, it should remind investors that when spreads are this tight and yields this high, the next shock could prove far more destructive to unhedged portfolios.

Frequently Asked Questions

How did the Israel-Iran conflict affect Treasury yields in June 2025?

The US strikes on Iranian nuclear facilities initially pushed Treasury yields higher on inflation fears as oil spiked to $78.50. However, the June 24 ceasefire triggered a sharp reversal, with 2-year yields plunging 16 basis points for the week as safe-haven demand overwhelmed inflation concerns.

Why did credit spreads tighten during such significant geopolitical turmoil?

High yield spreads compressed 10bp to 282bp as markets immediately priced in the ceasefire's positive resolution. Strong technical conditions and persistent reach-for-yield behavior overwhelmed fundamental concerns, pushing spreads to just the 24th percentile of their 5-year range despite obvious risks.

What caused oil prices to crash 7.2% on June 24, 2025?

The US-brokered ceasefire announcement at 04:00 GMT on June 24 immediately eliminated supply disruption fears that had driven oil to $78.50. The single-day collapse to $68.51 ranked among WTI's sharpest declines ever as inflation premiums evaporated within hours of the diplomatic breakthrough.

How does the $27 billion June fiscal surplus impact Treasury issuance?

June's surprise surplus, driven by record 18.2% effective tariff rates, temporarily reduced Treasury's borrowing needs but raised questions about revenue sustainability. While near-term issuance pressure eased, markets remained skeptical that tariff revenues could meaningfully address structural deficits given their economic drag.
