Oil Shock from Iran Conflict Drives Markets Lower as Yields Surge
The conflict with Iran remains the dominant force shaping global financial market behavior, primarily through its impact on surging oil prices. With Brent crude climbing above $100 per barrel, equity markets have consistently come under pressure while Treasury yields continue to creep higher. Concerns over the potential drag on global economic growth are weighing heavily on stocks, even as rising inflation expectations push interest rates upward.
Iran’s continued threats, its refusal to signal de‑escalation, and ongoing attacks on cargo vessels in the Strait of Hormuz have only intensified market anxiety. Despite occasional statements from President Trump suggesting that Iran was “about to surrender,” there is little evidence that hostilities are nearing an end.

Once the 10‑year Treasury yield moved decisively above the 4% mark - coupled with inflation risks stemming from elevated oil prices - we set our sights on the January peak closing level of 4.29%, with an interim technical checkpoint at 4.21%. By Friday afternoon, the 10‑year had nearly reached that upper bound. Treasury futures have clearly outlined the key support and resistance zones throughout this period, presenting compelling short‑position opportunities as yields pushed higher over the past two weeks, of which we have taken advantage in our positioning.
Looking forward, interest rates are likely to track the volatility of oil. Technical levels suggest notable resistance slightly above the current range, and from a purely technical perspective, once the 4.33% level is breached and supported, there is limited impediment to a further move toward 4.49% - particularly if crude prices resume climbing and break above the previous ~$120 per‑barrel peak. Should this breakout occur, I plan to increase short exposure to capitalize on the next leg higher.
On Friday morning, core PCE for January arrived largely in line with expectations, registering a year‑over‑year increase of 3.1%. Importantly, this data does not yet reflect the price impacts stemming from the Iran conflict, which implies upward pressure in upcoming first‑quarter readings. Meanwhile, the second estimate of fourth‑quarter GDP was revised down from 1.4% to 0.7%, offering momentary hope to dovish investors that the Federal Reserve might adopt a more accommodative stance. However, by the market close, renewed inflation concerns - driven by higher oil - had reasserted themselves, pushing yields up and leaving equity markets firmly in negative territory.
From the Municipal Desk:
Municipal yields generally tracked the direction of Treasuries but ultimately underperformed, rising at a faster pace than comparable government rates over the past week. This outcome was largely anticipated, given that municipals had shown modest outperformance the prior week as the initial move toward higher rates began to take shape. Despite the weaker price action, dealer bid‑side levels held up reasonably well, providing stability through the volatility.
Investors welcomed the opportunity to buy at the most attractive absolute yield levels seen since January, taking advantage of pockets of value across the curve. Meanwhile, this week’s lighter supply - declining to roughly $9 billion from last week’s $13.3 billion - may create enough of a supply/demand imbalance to keep buyers engaged and maintain competitive dealer bid‑side support.
As we approach the April 15 tax deadline, the municipal market typically experiences a seasonal slowdown, as investors redirect liquidity toward tax payments and defer reinvestment decisions. During this period, municipal‑to‑Treasury ratios are likely to improve, offering more compelling relative value as the market adjusts to shifting demand dynamics.
