McGeever: The war in Iran traps Treasuries' investors in an oil stagflationary dilemma.

U.S. Treasuries have just had their best month since last year. Investors must now decide whether the sudden outbreak of war in the Middle East will boost the bond market rally, or if a surge in oil prices will cause it to crash.

The U.S. and Israeli attack on Iran, which resulted in the death of Supreme Leader Ayatollah Khamenei, on Saturday marked a dramatic 'escalation' in tensions in the region. The simmering conflict has already pushed Brent crude prices above $70 per barrel in recent weeks. It also sparked investor appetite for Treasuries, pushing the 10-year yield down to below 4%.

These two moves both accelerated dramatically in the early trading of Monday.

Brent oil soared by as much as 14 percent, and Brent broke through the $80/bbl mark, amid fears of disruptions in supply from one of the world's largest producing regions. The 10-year Treasury yield fell to 3.90% - its lowest level since last April.

The buying frenzy cooled down, particularly at the short end, where the yield on the 2-year Treasury note flipped and traded 6 basis points higher.

Bond investors face a dilemma: should they buy Treasuries as a hedge against a possible slump in risky assets due to a spike in geopolitical risks, or should they sell them in anticipation of inflation and a possible Federal Reserve response due to the soaring price of oil?

Which half of "stagflation's" dynamic will win out?

FLIGHT TO SAFETY

Investors' first instinct was to seek cover. The allure of Treasuries, and other high-rated government bonds, seemed overwhelming as stocks fell around the globe. On Monday, the majority of Asian and European benchmark equity indexes dropped between 1% to 2%. European yields also initially declined.

It's easy to understand, given the potential crushing impact of rising oil prices on economic development.

Jordan Rochester, a Mizuho analyst, estimates that an increase of $10/barrel will knock 10-20 basis point off the growth rate for the next year. Oil has already risen by $20/bbl over the past six weeks and could reach $100/bbl soon. The global economy would be severely affected if crude rose above this threshold and stayed there.

The "bull" case is strong for Treasuries, especially when you consider the looming threat of AI to white-collar jobs in the next few years.

OIL NOW +13 % YEAR-ON-YEAR

The "risk-off" trade that immediately followed the U.S. - Israel strikes sparked a flood of demand for Treasuries. However, a persistent rise in oil prices ultimately pushes all other prices higher.

Analysts at Rabobank note that a significant increase in oil prices is inflationary. "Just as it was during the Russian invasion of Ukraine", they say.

According to economists, a $10 increase in oil can boost the annual inflation rate by up 0.2 percentage points. This might not seem like much. The Fed's preferred annual inflation measure is already at 3%, and it is creeping up. So every increase counts.

Mizuho’s Rochester said oil at $100-$130/bbl for any period of time would not just take Fed rate reductions completely off the table but also trigger a mild cycle of rate-hiking "at least".

The broad-based price pressures are already pushing prices higher in the U.S. The data on producer price inflation for January, released last Friday, was hotter than anticipated. And the deflationary pressure from oil is now turning into an inflationary one.

Brent crude's price increased by a positive amount last week. If this trend continues, it will mark the first time since 2024 that oil's "base effect" will exert upward pressure rather than downward on annual inflation calculations.

Brent crude was nearly 30% cheaper in early January than it had been a year before. It is now 13% higher than a year ago. This is a major shift in the inflation models that will cause Fed officials to be on alert.

Energy and motor fuel account for a combined weighting of more than 9% on the U.S. Consumer Price Index. $100/bbl could translate to a 0.8-1.5% rise in the CPI, if sustained and fully reflected in increased gasoline prices.

It is possible that this figure could be significantly underestimated, if rising oil prices also increased housing, transportation, food, and other costs.

Treasuries have fallen from the highs they reached on Monday morning. The conflict in 'the Middle East' is fluid and appears to be spreading, so sentiment can change in an instant.

The jobs of Treasuries' investors just got harder.
