At APPEC, Mark Senn shared how evolving markets are shaped by three A’s – access, agility and adaptability – and how a fourth A, asset-backed trading, turns insight into action

In September, The Asia Pacific Petroleum Conference opened a week of oil-market conversations in Singapore at a moment when geopolitics, sanctions, disrupted trade routes, refining outages and low inventories were testing how quickly the system could adapt.
For Phillips 66, APPEC provided an opportunity to bring an asset-backed commercial perspective to that discussion.
Mark Senn, senior vice president of global trading, participated in an opening morning fireside chat to examine how companies can use physical flexibility, global market insight and market access to respond when conditions change.
A market with less slack
When asked what defines the current price regime, Senn pointed to a tighter system in which disruptions can move quickly across regions and markets. He said that dynamic makes it critical for companies to connect market insight with physical assets and logistics — and act before a local disruption becomes a broader supply challenge.
“The system has less slack, and disruptions travel faster through the system,” Senn said. “That is why trading, logistics and asset flexibility have become strategic capabilities.”
“The market is no longer defined by price alone. It is defined by who has access to supply, logistics and customers — and who can adapt when the route changes.”

Commercial as a strategic capability
That perspective led directly to Commercial’s role within Phillips 66.
“Commercial is no longer just optimizing a margin after the fact,” Senn said. “It is helping the company decide where to source, how to move supply, which market to serve and how to protect the customer relationship.”
At Phillips 66, Commercial connects the company’s integrated asset base — from supply and refining to logistics and trading — with market opportunities and energy demand around the world.
Its asset-backed trading model allows teams to see the business as one system rather than a series of isolated transactions, helping the company understand how disruptions affect physical flows and what it takes to keep customers supplied.
Putting the system to work
Senn pointed to the company’s response to recent disruption as an example.
“We did not respond to the conflict with one trade or one asset,” Senn said. “We responded with the system: reliable supply, flexible refining, logistics reach, market access and disciplined optimization working together.”
Connecting the portfolio to the market
That idea is not theoretical. Phillips 66’s recent earnings calls provide a real-world view of how the system works.
On the first-quarter call, company leaders described moving Bakken crude through Beaumont and on to Bayway, placing Gulf Coast gasoline into West Coast markets and using the global footprint to deliver LPG and naphtha to customers around the world. They also highlighted the Singapore team’s role in optimizing delivered LPG supply through time-charter capacity.
On the second-quarter call, executives said the time-charter fleet had grown fourfold over two years, supporting roughly 40 percent of asset-backed demand while creating a third-party opportunity.
Taken together, these examples show what Senn meant by responding with the system: connecting market insight, physical assets and logistics to keep molecules moving, support customers and strengthen the resilience of the integrated portfolio.
Beyond the stage
The conversation’s themes also extended beyond the APPEC stage through post-event media coverage. That attention underscored broader industry interest in how companies are navigating tighter systems, changing trade routes and a growing focus on energy security.
What it means for Phillips 66
For Phillips 66, the conference was also an important opportunity for the Singapore Commercial office to connect with customers, counterparties and industry peers across Asia Pacific.
Those relationships reflect a broader value proposition: Phillips 66 helps customers navigate changing conditions with reliable supply and resilient routes. Its asset-backed platform gives Commercial more options to respond and deliver practical solutions.
Ready for what comes next
In his closing, Senn explained that markets will continue to re-optimize, but the more durable advantage lies in the ability to operate safely and reliably, preserve optionality and manage risk with discipline.
That is the role Commercial plays at Phillips 66: connecting the company’s assets and capabilities to customer needs, turning market insight into action and helping provide energy where it is needed.
