Oil above $100, G7 in crisis mode, and a Fed boxed in by war-driven inflation — this week, the Iran shock isn't background noise. It is the portfolio story.

This Week's Income Strategy Tip

Lock in 6-Month T-Bills at >5% While the Fed Stays Frozen

With headline CPI at 3.8%, core at 2.8% and rising, and Lazard's chief strategist explicitly stating that Fed easing is "off the table," there is no near-term catalyst to push short-term yields lower. That makes 6-month Treasury bills — currently yielding above 5% — the highest-confidence risk-adjusted income vehicle available right now. Here's how to act on it this week:

1. Buy 26-week (6-month) T-bills directly via TreasuryDirect.gov at the next weekly auction (typically Mondays), or purchase the iShares 0-3 Month Treasury Bond ETF (SGOV) or SPDR Bloomberg 1-3 Month T-Bill ETF (BIL) for same-day liquidity — both currently yield above 5% annualized and carry near-zero duration risk.
2. Set a yield floor of 5.00%. If the 6-month T-bill yield at auction falls below that threshold, re-evaluate; otherwise roll proceeds at maturity. Do not extend to 2-year or longer durations until 10-year Treasury yields stabilize and Iran-war energy premium subsides.
3. Avoid intermediate-duration bond funds (e.g., AGG, BND) until the geopolitical oil premium clears. With G7 borrowing costs spiking and global oil inventories falling at a record pace, duration risk remains asymmetrically to the downside in May and likely June.

Iran War Drives Friday Selloff: Energy Rises as 10 of 11 S&P Sectors Fall

Wall Street closed sharply lower on Friday, May 16 — with the Dow shedding 537 points, the S&P 500 losing 1.2%, and the Nasdaq falling 1.5% — as rising oil prices and renewed Iran war concerns hammered sentiment. The lone bright spot was Energy (XLE +2.3%), confirming that the conflict's market footprint is now a sector-rotation story, not just a macro headline: Materials fell 2.7%, Utilities 2.4%, and Industrials 1.8%, while NVIDIA dropped 4.4% on the day. (Note: Friday's close data is from May 16; Monday May 18 markets are open as of this writing, with the S&P near 7,403.)

Hot Core CPI + $4.50 Gas: The Fed Is Stuck and May Inflation Will Be Worse

April CPI data released May 12 showed headline inflation at 3.8% year-over-year — up from 3.3% in March — while core CPI (excluding food and energy) came in at 2.8%, above the 2.7% consensus and its highest reading since September. Lazard's Chief Market Strategist Ronald Temple was blunt: "Fed easing appears to be off the table, but rate hikes are unlikely." Critically, he warned that May's CPI print will likely be even higher: with gas averaging $4.50/gallon now versus ~$4.00 in April, gasoline alone is poised to contribute 40 basis points to the next headline number — meaning this is not the peak.

G7 Finance Ministers Meet in Paris as Bond Costs Spike and Oil Inventories Hit Crisis Levels

G7 Finance Ministers and Central Bank Governors convened in Paris on Monday with the Iran war's economic shock dominating the agenda; Eurogroup President Kyriakos Pierrakakis called opening the Strait of Hormuz "of the utmost importance." The gathering comes as borrowing costs across G7 nations have spiked in recent weeks, global oil inventories are falling at a record pace, and strategists warn European oil shortages could materialize within weeks — a supply crunch that one analyst described simply as "bad," with depletion risks extending into 2027. Separately, a Putin-Xi meeting in Beijing is scheduled for Tuesday, adding another geopolitical layer to an already fraught week for global markets.

The Six-Week Rally That Was: Jobs Beat Fueled Records on May 8 — Before Iran Reset the Tape

Context matters: just ten days ago, on May 8, the S&P 500 and Nasdaq were setting fresh all-time closing records on the back of a blowout April jobs report — employers added 115,000 jobs versus 55,000 expected — capping the index's sixth consecutive week of gains. That optimism has since been unwound by the CPI miss and escalating war risk, illustrating how quickly the macro narrative can flip. As Zacks strategist Brian Mulberry noted at the time, the jobs data "pushes away fears of recession any time soon" — but also raises the probability that stagflation conversations "will heat up if prices begin to dig into wages over the summer."

AI Venture Funding Surges to $37B in April — Anthropic and Bezos's Project Prometheus Lead

Global venture funding hit $56 billion in April — up 100% year-over-year from $26 billion — making it the third-largest monthly funding total in the past year, driven by a $15 billion raise for AI lab Anthropic and a $10 billion round for Jeff Bezos's AI manufacturing venture Project Prometheus; together they accounted for 45% of all April venture capital. AI overall commanded $37 billion, or 66% of global VC, with AI model companies alone raising $26.7 billion — a concentration of capital that underscores why Berkshire's return to airline stocks (a $2.6B Delta stake) and DRAM ETF records are part of the same theme: the market is repricing every asset class through the lens of what AI can and cannot replace.
