Sparta in action: How Sparta called the Singapore regrade correction early
How Sparta called the Singapore regrade correction early
When Singapore regrade was pushing higher in early December, the market still looked comfortable.
Sparta didn’t see it that way.
Six days before the move, our signals were already pointing to stretched structure and downside risk, well before prices rolled over.
This is a breakdown of what we saw, when we saw it, and how desks using Sparta were positioned ahead of the regrade correction.

Setting the stage: Regrade at $1.45/bbl (3 Dec)
On the surface, Singapore regrade looked strong.
But underneath, the structure was starting to fray.
Sparta’s live market intelligence was already flashing warnings.
1. Jet arbitrage outlets were closed
Sparta’s Pricing Centre showed regrade-linked jet barrels had nowhere to go.
LR2 arbs from North Asia into Singapore were shut.
MR arbs from Asia into LA were closed.
LR2s from AG and WCI into Europe were no longer workable.
With no clear flow outlets, surplus jet pressure was building.
2. Jet yields were maxed
Refiners were already running at high jet yields.
Sparta commentary flagged that additional upside would require demand to absorb even more jet. That demand wasn’t there.
Volatility remained elevated, a clear sign the structure was stretched.
3. Volatility was signalling exhaustion
Regrade volatility stayed high as prices pushed up, but without fresh structural support.
This combination historically does not persist.
On 3 December, Sparta Knowledge flagged it clearly:
“Strong regrade is ripe for correction, with max yields now being signalled.”
The call was simple: regrade cracks.
What happened next
By 9 December, Singapore regrade had fallen from $1.45/bbl to $0.90/bbl.
A 55 cent move.
A 38 percent drop in under a week.
Exactly the turn Sparta warned about in advance.
