Will Monaco’s two-stop rule prevent a Sunday procession?

The Monaco Grand Prix, Formula 1’s crown jewel, is set to deliver a fresh twist this weekend with a bold tyre strategy overhaul.

For a second consecutive race, Pirelli has selected the three softest compounds from its 2025 range. As in Imola last week, the C4 will be the Hard, the C5 the Medium and the C6 the Soft, with the first two being the mandatory compounds for the race.

But the real game-changer is a new rule requiring drivers to make two mandatory pit stops, a move by the FIA and F1 intended to spice up a race notorious for its processional nature.

With the Principality’s tight streets making overtaking a nightmare, this regulation aims to spark strategic creativity, potentially turning tyre choices into the key to victory.

Two-Stop Rule: A Catalyst for Drama?

Monaco’s 2024 race was a snooze, with the field locked into predictable one-stop strategies and minimal action. To counter this, the FIA has introduced Article 30.5, paragraph m of the sporting regulations, which mandates that each driver must use at least three different tyre types (dry or wet) during the race.

If intermediates or wets aren’t used, drivers must deploy at least two different slick compounds, one of which must be the Hard or Medium. Failure to comply risks disqualification or a hefty 30-second penalty for using fewer than two slick compounds, with an additional 30 seconds for using only one tyre set.

To accommodate potential wet conditions, each driver receives an extra set of Full Wet tyres on top of the standard two, ensuring the two-stop rule applies regardless of weather.

This shake-up could transform Monaco’s strategic landscape. With no clear pit-stop windows, teams face a puzzle: when to pit, and which compounds to prioritize.

The low tyre degradation at Monaco, where the smooth asphalt and tight corners minimize wear, reduces concerns about tyre life, opening the door for aggressive strategies.

The C6 Soft, typically a qualifying darling, could see race action, especially for late second stops or during Safety Car periods.

Sky F1 pundit Jacques Villeneuve predicts unorthodox approaches.

“With two obligatory pit stops there might be some strange strategies. Maybe a team will wait until the last five laps to do their two stops, then hope for a Safety Car. It will be odd…”

Indeed, late pit stops could play a decisive role – especially in a race where a well-timed yellow flag can completely reshape the running order. The unpredictability introduced by this rule may well be the catalyst Monaco needs to deliver the kind of dramatic racing fans crave.

The Challenge Ahead

While tyre degradation remains low in Monte Carlo due to the circuit’s low-speed nature and smooth asphalt, managing the timing and sequence of two stops around the tight streets and potential traffic could prove to be a greater challenge than managing the tyres themselves.

And for the drivers, there’s an added layer of pressure. Strategy calls will need to be precise, pit crews flawless, and any Safety Car intervention instantly capitalised on.

The blend of strategic complexity and the ever-present threat of barriers means this year's Monaco Grand Prix is shaping up to be far more than the usual parade.

Whether it brings chaos or calculated brilliance, one thing is certain: Monaco 2025 won’t be business as usual.
