How Sparta flagged the Singapore GO E/W tightening early

In late January, the GO E/W spread was deeply discounted.

Most of the market saw the structure as stretched, but not urgent.
Flows still looked active on paper. The downside felt contained.

Sparta saw something different.

Days before the move, Sparta’s signals were already pointing to a tightening setup: Singapore inflows were drying up, LR2 flows were redirecting West, and seasonals showed the structure was historically overstretched.

This is what we saw, when we saw it, and how Sparta users were positioned before the move.

Setting the stage: GO E/W at –$41.75/mt (28 Jan)

On 28 January, GO E/W was trading around –$41.75/mt.

The market looked heavy.
Structure felt extended, but few expected a fast reversion.

Underneath the surface, though, supply dynamics were already shifting.

Sparta’s dashboards were flagging a clear imbalance: fewer barrels were able to reach Singapore, while structure sat at extreme seasonal levels.

What Sparta saw

1. Singapore inflows were drying up

Sparta’s Pricing Centre showed that all major ULSD arbitrages into Singapore were shut.

At the same time, AG/WCI LR2 flows were pointing West, meaning fewer barrels were heading into the region.

With inbound flows tightening, the structure became increasingly exposed.

No barrels in. Structure overstretched.

2. Seasonals flagged an extreme

Seasonals showed GO E/W trading at its widest February level in more than eight years.

Historically, extremes like this rarely persist.

Sparta’s tools highlighted that the spread was vulnerable to a fast reversion if supply tightened further.

3. Commentary called the tightening setup

On 28 January, Sparta commentary stated:

“With fewer barrels able to arrive… the path of least resistance remains higher for Singapore diesel cracks and spreads. A narrowing GO E/W likely to follow.”

The message was clear:

No supply.
Price had to correct.

What happened next

By 5 February, GO E/W had rallied sharply, tightening to –$32.75/mt.

From –$41.75/mt to –$32.75/mt in just one week.

That’s a +$9/mt move, or roughly +21%, in seven days.

Seasonal extremes reversed, exactly as flagged.
