Viewpoint: 2025 Hardisty heavy diffs may remain strong
Calgary, 31 December (Argus) — Heavy crude spot differentials in Alberta are
expected to remain strong into next year, even with growing oil sands production
and possible US import tariffs. After years of cost-overruns and construction
delays, the 590,000 b/d Trans Mountain Expansion (TMX) commenced on 1 May,
nearly tripling the capacity of crude able to reach Canada's Pacific coast and
providing Alberta oil sands producers with increased access to buyers on the US
west coast and Asia-Pacific. Extra egress capacity for Alberta crude westward
has pulled previously apportioned volumes away from Enbridge's 3mn b/d Mainline
system — Canada's main method of export to ship crude south to US refiners in
the midcontinent and Gulf coast. In the fourth quarter, apportionment averaged
just over 1pc for both light and heavy crude on the Mainline, significantly
lower than the average apportionment of 21pc for lights and heavies in the
fourth quarter last year. While president-elect Donald Trump's looming blanket
tariff on all Canadian imports would re-direct more Albertan crude westward via
TMX to Asia- Pacific buyers, many believe the tariff would be too harmful to US
midcontinent refiners for Trump to actually carry out his threat. Prior to TMX's
commencement, high apportionment combined with rising crude production heading
into the winter months forced more crude onto railcars, which typically requires
a $15/bl to $20/bl spread between Western Canadian Select (WCS) at Hardisty
Alberta, and Houston, Texas, for uncommitted shippers to profit. With the
redirection of apportioned volumes to buyers in the west, Canadian heavy spot
differentials in Alberta have strengthened in a quarter when discounts have
generally widened in recent years. Argus's WCS Hardisty assessment averaged a
$12.08/bl discount to the CMA Nymex WTI during fourth quarter Canadian trade
cycle dates, $11.52/bl stronger than the $23.61/bl discount averaged in the
fourth quarter a year prior. Yet, crude output in Alberta's key oil sands is
expected to rise heading into 2025, with production levels reaching record-high
levels this year. Alberta crude output was 4.2mn b/d in October, according to
the latest Alberta Energy Regulator (AER) data, up by 9.4pc year from a year
earlier and the second highest monthly production on record. Alberta oil sands
producers, meanwhile, have increased their crude production guidance for next
year. Suncor expects to pump out 810,000-840,000 b/d across its upstream sector
in 2025, up by 5pc from 2024. Cenovus expects to increase production next year
by 4pc to between 805,000-845,000 b/d of oil equivalent (boe/d), and Imperial
Oil plans to boost upstream production by 2pc to 433,000-456,000 boe/d. Egress
capacity remains ample despite rising production heading into 2025. Total crude
pipeline egress capacity out of Alberta is expected to be over 4.6mn b/d in
2025, with shippers still yet to utilize uncommitted space on the 890,000 b/d
Trans Mountain pipeline. About 712,000 b/d or 80pc of the system is reserved for
contracted shippers, with the remaining 20pc available for uncontracted
shipments. With unconstrained egress capacity expected to persist, Suncor and
Cenovus have both assumed WCS at Hardisty will average a strong $14/bl discount
to WTI in 2025. In the near term, Trump's plans to impose a blanket 25pc tariff
on all Canadian imports would threaten some US demand for Canadian crude. Yet,
while some traders are pricing in the reality of US tariffs, most market
participants are skeptical of whether Trump's tariff plans would extend to
Canadian crude due to the co-dependency between Albertan producers and some US
refiners. US midcontinent refiners, many of whom were financial backers of
Trump's 2024 presidential campaign, are dependent on Canadian crude given a lack
of access to alternative heavy sour crudes suited for their refineries. Canadian
grades represent approximately 70pc of the US midcontinent refinery feedstock,
with the remainder largely sourced in the US. US importers may take more crude
from countries including Saudi Arabia, given the country has plenty of spare
capacity to increase the production of heavy sour crude favored by US
midcontinent refiners. However, replacing Canadian crude with waterborne
supplies would result in a substantial increase in tanker demand. In August,
only around 370,000 b/d of the 3.8mn b/d of Canadian crude imported by US
refiners moved on tankers, Vortexa data show. Even if US refiners can replace
Canadian and Mexican heavy crude, they are expected to face higher landed costs
and, potentially, less reliable supplies. By Kyle Tsang Send comments and
