As of March 29–30, 2026, markets are already trading an Iran-war stagflation shock: Reuters reports Brent around $115, WTI around $103, S&P 500 futures down, and 10-year Treasury yields up roughly 47 bps in March as investors price higher inflation and weaker growth. Fed officials have also said the war has shifted risks toward inflation, not easier policy. In other words, the live market is not behaving like a clean “risk-off, buy duration” episode. (Reuters)

Your full scenario is more extreme than current reality: not just a long war, but a perceived U.S. strategic defeat, a break in the petrodollar bargain, and a lasting downgrade in U.S. geopolitical primacy. I would treat that as a regime-break stress, not a normal recession stress. Current reporting says the petrodollar foundations are being tested, not yet broken, and the dollar still dominates reserves, FX trading, and foreign-currency debt issuance. The IMF put the dollar at 56.77% of disclosed reserves in 2025 Q4; the BIS says it was on one side of 89.2% of global FX trades in April 2025; the Fed says foreign investors held about $9 trillion of Treasuries in Q1 2025, and Treasury’s June 2025 survey put total foreign holdings of U.S. securities at $35.3 trillion. That means a true break would probably be a multi-quarter repricing, not an overnight disappearance of dollar centrality. (Reuters)

What happens next, in that tail scenario, is this: the first phase is likely a liquidity squeeze and inflation shock. The dollar can rise initially because it remains the most liquid funding currency and the U.S. is still relatively less exposed than big energy importers; Reuters has already reported that pattern in the current conflict. At the same time, oil stays high or goes higher, inflation expectations rise, and long Treasury yields back up rather than hedge. Reuters cited a JPMorgan scenario of oil moving toward $150 if the Strait disruption persists another month, and the IMF said every persistent 10% rise in oil adds about 40 bps to global headline inflation and cuts global output by 0.1–0.2%. My inference is that the first move in your scenario is higher U.S. yields, wider credit spreads, lower equity multiples, and a stronger dollar before any later structural dollar weakening. (Reuters)

For the U.S. stock market, I would expect a broad derating, not just an earnings recession. Higher oil hits margins and demand; higher long yields hit valuation multiples; and any loss of reserve-premium or security-premium hits U.S. assets directly. The biggest casualties would likely be long-duration growth, small caps, levered cyclicals, rate-sensitive sectors, and any equity style dependent on cheap capital. Energy, defense, some materials, and selected infrastructure names would probably outperform on a relative basis, but in a severe de-risking they may still fall in absolute terms. The key point is that under this regime-break stress, the market is not just discounting slower GDP; it is discounting a higher U.S. risk premium. That is my inference from the current oil-shock pricing, rising yields, and the strain now visible in the petrodollar/security arrangement. (Reuters)

For bonds, I would separate the front end from the long end. Long nominal Treasuries are the vulnerable sleeve because they absorb inflation risk, fiscal risk, and any foreign reserve diversification. That vulnerability is amplified by the fact that Treasury-market liquidity has already been described by the Fed as low by historical standards, while FSOC warned that highly leveraged hedge-fund basis trades have become an important but unstable source of Treasury demand. In this tail, the long end can sell off even as growth deteriorates. By contrast, very short bills still retain utility as collateral and dry powder, and TIPS should be structurally better than nominal duration. (Federal Reserve)

For gold, the lesson from the current war is important: gold is not guaranteed to rally immediately in a liquidation phase. Reuters reported it falling because a firmer dollar, higher oil, and fading rate-cut hopes raised the opportunity cost of holding it. But medium term, gold is still the cleaner hedge against reserve diversification and credibility loss. The Fed notes that gold’s share of official reserves has more than doubled since 2015, and the World Gold Council says 95% of surveyed central banks expect global gold reserves to rise over the next 12 months while 73% expect lower U.S. dollar holdings in global reserves over five years. So in your stress test I would model gold as down or flat in phase one, then strongly positive in phase two. (Reuters)

For bitcoin, I would not treat it as core insurance. The live tape in this conflict shows bitcoin selling off with broader risk, and the academic evidence remains mixed: some recent papers find safe-haven properties against geopolitical crash risk, while others still find bitcoin behaves more like a high-beta risk asset in real stress episodes. That makes BTC an optionality sleeve, not a dependable hedge. In a genuine U.S.-credibility break, bitcoin could rebound later on a “hard-money / anti-fiat” narrative, but the first move is still likely to be a sharp drawdown and forced deleveraging. (MarketWatch)

So the portfolio answer is not “sell everything and buy gold.” It is: cut duration, cut beta, raise liquidity, add inflation convexity, and own regime-break hedges that survive both liquidation and de-dollarization. Concretely, I would do six things.

First, shrink broad U.S. equity beta, especially long-duration growth, levered cyclicals, small caps, and financials sensitive to higher long yields. Keep only high-quality franchises with pricing power and low refinancing risk. Add relative overweight to energy, defense, and hard-asset-linked equities, but do not assume they fully offset a market drawdown. This follows directly from the current oil/inflation/rates mix. (Reuters)

Second, remake the bond book. Move a large share of nominal duration from the 7–30 year area into 0–2 year bills and TIPS. In this scenario, the bond sleeve should be a liquidity and inflation-defense sleeve, not a duration bet. Long Treasuries may eventually rally in a deep recession, but that is not the stress you asked for; your stress is a U.S. credibility shock, and in that case the long end is where pain sits. (Federal Reserve)

Third, keep or increase gold, but hold it in unlevered form. Gold has proven it can get sold to meet margin calls, so the position should be resilient to near-term drawdowns. I would think of it as strategic reserve insurance, not tactical momentum. Current central-bank behavior supports that framing. (Reuters)

Fourth, reduce bitcoin to a capped risk budget. If you want to keep the upside to a later anti-dollar narrative, size it like venture capital or deep convexity, not like core ballast. If BTC is doing your hedging job, the portfolio is underinsured. (Barron’s)

Fifth, add explicit convex hedges if your mandate allows them. The cleanest hedge to this scenario is energy upside plus equity downside: oil call structures, energy-equity exposure, S&P/Nasdaq puts or put spreads, and—in institutional books—rate-vol or curve-steepener hedges. If the concern is a forced repricing of U.S. term premium, payer structures on long-end rates are more aligned than owning more long bonds. That is an inference from the current market move in oil, yields, and equity futures. (Reuters)

Sixth, run the stress test in three horizons, not one. For 1–5 trading days, assume liquidity stress: equities down hard, BTC down harder, gold mixed, dollar up, long yields up. For 1–3 months, assume oil remains elevated and growth weakens: more equity pain, tighter financial conditions, TIPS outperform nominals. For 6–24 months, assume reserve diversification and petrodollar erosion: weaker structural dollar, higher U.S. term premium, lower U.S. equity multiples, stronger gold, and better performance from real assets and selectively from non-U.S. exposures tied to commodity production rather than energy imports. That sequencing is the most important design feature of the stress test. (Reuters)

If I had to summarize the positioning in one sentence: prepare for stagflation first, de-dollarization second. In portfolio terms, that means less U.S. beta, much less long nominal duration, more bills and TIPS, a durable gold allocation, smaller bitcoin, and explicit convex hedges tied to oil and equity downside. (Reuters)

The grid below is built for a regime-break stress, not a normal recession: first an oil shock and liquidity squeeze, then a higher U.S. risk premium, and only later a deeper challenge to dollar primacy. That matches the current tape better than a classic “stocks down, long Treasuries up” framework: Reuters reports oil surging, equities weakening, the dollar firming, and Treasury yields rising as the Iran war widened, while the Fed’s 2025 Financial Stability Report said Treasury-market liquidity had been low by historical standards in a prior volatility episode.

How to build each sleeve

Sleeve
Construction

Stocks
Keep 60–70% of equity exposure in energy, defense, materials, pipelines, utilities, and quality cash-generative value; keep 30–40% in broad quality/global franchises. Underweight long-duration tech, REITs, small caps, regional banks.

Bonds
Of the bond sleeve, put roughly 55–65% in 0–6 month bills, 25–35% in TIPS, and only 10% or less in nominal duration beyond 7 years.

Gold
Prefer unlevered physical-backed exposure or fully funded instruments.

Bitcoin
Treat as a capped optionality sleeve, not ballast. Rebalance mechanically if it rallies.

Use:

S&P 500 / Nasdaq put spreads instead of naked puts where carry matters.

Brent or energy-equity upside hedges for the oil shock.

Long-end rate payer structures rather than owning more long Treasuries.

Execution order

Immediately: cut long nominal duration and high-beta equity.

Next: raise bills, TIPS, and gold.

Then: rotate equity book toward resource/defense/value.

Finally: cap BTC risk and add overlays.

The single biggest mistake to avoid

Do not run this stress as if it were a standard recession. In the current Iran-war backdrop, the market has already shown that oil can surge while stocks fall and Treasury yields rise, which is exactly the setup where long nominal bonds fail as the main hedge. (Reuters)
1) Scenario Tree (Macro Regime Outcomes)

3) Portfolio Allocations by Scenario
Scenario A Portfolio (Pro-US Recovery)

This is closest to a traditional portfolio:

US equities: 50%

International equities: 15%

Bonds (UST): 20%

Commodities: 5%

Gold: 5%

Bitcoin: 5%

Optimized for growth + disinflation

Scenario B Portfolio (Multipolar / Inflation Regime)

Shift toward real assets:

US equities: 25%

International equities: 20%

Bonds: 10% (short duration only)

Commodities (energy-heavy): 20%

Gold: 15%

Bitcoin: 5–10%

Cash (non-USD diversified): 5%

This is a 1970s-style portfolio

Scenario C Portfolio (US Structural Decline)

This is the true stress-case positioning:

US equities: 10% (mostly energy/defense)

International equities: 25% (commodity exporters)

Bonds: 0–5% (avoid duration risk)

Commodities: 30%

Gold: 20%

Bitcoin: 10%

Cash (multi-currency): 5%

This is anti-fragile to dollar collapse

4) Blended “Macro Hedge Fund” Allocation

Now the key question:

What do you hold TODAY given uncertainty?

We weight by probabilities:
Final Blended Allocation

US equities: 28%

International equities: 20%

Bonds: 10% (short duration bias)

Commodities: 18%

Gold: 14%

Bitcoin: 7%

Cash (diversified FX): 3%

5) Why this works (important)

This portfolio is intentionally:
Underweight the biggest hidden risk

Long-duration bonds

Not overexposed to one regime

Still participates if US wins

Long real assets

Protects against inflation + war

Has convexity

Gold + Bitcoin = regime-break hedges
