Crude Oil Volatility Surface Prices Hormuz Risk as a Core Factor
nashnova research
Brent crude is back above $100/barrel, and Bloomberg strategist Frank Monkam argues the move marks more than a price milestone — Hormuz Strait risk has graduated from a tail event to a core input in the volatility surface, meaning the options market may never return to its old calm.
Brent broke $100 — why is this more than a price event?
Brent cleared the $100 psychological level, but the deeper signal sits in the options market: the volatility regime — the market's overall framework for pricing future price swings — has shifted.
This means → it is not simply that oil is more expensive; the market has repriced volatility itself, expecting larger and more persistent swings ahead.
The call comes from Bloomberg macro strategist Frank Monkam.
Why is skew volatility "stuck" at elevated levels?
The 30-day realized volatility of Brent's 1-month 25-delta call skew — a measure of how much extra protection traders demand against upside moves — currently sits at roughly 9 vol points.
Historically, skew vol mean-reverts after each geopolitical shock, dropping back to a low-single-digit baseline of about 2.0. This time it pulled back from extreme peaks but never returned to the old baseline.
In plain terms = after past scares, the market "forgot" within weeks; this time the anxiety is still embedded in every quote, and normalization is clearly incomplete.
How did Hormuz change its identity in the pricing framework?
Hormuz disruption used to be the oil market's "doomsday risk" — extremely low probability, triggering a rush for upside protection only when tensions flared.
Now, a Strait closure has become a persistent input into the physical supply outlook: traders must continuously reassess not just the probability of disruption but also its duration and severity.
This means → the risk has moved from "an occasional scare" to "a constant that must be modeled every day," making the shape of the volatility surface inherently less stable.
What does the new regime mean for the oil options market?
Monkam's conclusion: the new regime does not necessarily require implied volatility to stay permanently elevated, but upside skew will be structurally more volatile and will settle at a higher baseline.
In plain terms = oil options will not sit in permanent panic mode, but the "floor during calm periods" is now higher, and each new shock will produce wider swings than before.
Whether Hormuz risk can truly retreat from "core risk" back to "tail risk" is the key test for whether the options market can return to its old equilibrium.
