Phillips 66 is a publicly traded company in the Energy sector. This company operates across Energy and is subject to various Congressional legislative and regulatory actions. HillSignal is tracking 17 active Congressional signals mentioning Phillips 66, including 17 bills. The current legislative sentiment is predominantly bullish, suggesting potential tailwinds from government policy.
HR 8519, introduced April 27, 2026, by Rep. Mast (R-FL), mandates an EPA waiver of summer Reid Vapor Pressure (RVP) limits on gasoline from May 1 to September 15, 2026. The bill is in early legislative stages (referred to House Energy and Commerce). If enacted, it would reduce refinery production costs for summer gasoline by allowing cheaper butane blending, benefiting independent refiners like Valero, Phillips 66, and Marathon Petroleum. No market data is available for price impact analysis.
→ Reduces need to produce or purchase lower-RVP blendstocks (alkylate, reformate) and allows increased butane blending, lowering per-gallon production cost by $0.02–$0.05 during the May–September window.
HR 8600 is an early-stage bill referred to the House Ways and Means Committee on April 30, 2026. It proposes a conditional fuel excise tax reduction tied to gasoline prices above $3.99/gallon, offset by suspending certain oil and gas tax deductions (intangible drilling costs). The bill has zero near-term market impact as it has not passed committee, let alone either chamber.
→ Reduced excise tax liability on fuel removed during high-price months; tax rate decreases proportionally to price above $3.99 threshold, lowering per-gallon cost for refiners
HR7688 (DPA Modernization Act) reduces regulatory risk for domestic energy producers by limiting presidential DPA emergency powers, combined with a concurrent Presidential Determination supporting petroleum and refining. Energy stocks XOM, CVX, PSX, MPC rose 4-10% in the 7 days after the 41-0 committee vote on March 4 and the Presidential Determination, while defense primes LMT, NOC, GD, RTX continue significant 30-day declines of 7-17% unrelated to this bill.
→ Reduced regulatory uncertainty for refinery operations and logistics. The bill prevents the President from redirecting refined product flows or NGL supply away from commercial markets for extended periods, preserving normal refinery feedstock arrangements and product distribution.
SCONRES33 is a congressional budget resolution that sets overall revenue and spending levels for FY2026-2035 and provides reconciliation instructions. It does not directly authorize or appropriate funds for any specific program, company, or sector. The resolution has passed the Senate but awaits House action, and no direct linkage to energy producers or other companies can be made from the bill text alone.
HR8330, introduced April 16, 2026 and referred to the House Judiciary Committee, proposes a broad liability exemption for all energy companies across the full hydrocarbon value chain. The market has already been accumulating energy equities over the past 7 trading sessions, with refiners MPC (+9.97%) and PSX (+8.79%) leading sector gains, suggesting institutional recognition of this pro-energy regulatory trajectory. Combined with the April 20 DPA determinations and recent presidential permits for Enbridge, the administration is building a comprehensive policy floor for energy infrastructure investment.
→ eliminates a class of downstream legal risk that could otherwise force refiners to change product specifications or face cleanup liabilities tied to consumer-end emissions
HR8204, the Western Refined Fuel Reserve Act of 2026, is an early-stage bill authorizing a storage reserve for gasoline, diesel, and jet fuel in Western states. Critically, it contains no appropriation of funds for construction or operations, rendering any market impact negligible until separate funding legislation is passed.
HR8266 is early-stage legislation with low passage probability. The bill proposes a gasoline export ban when US average prices exceed $3.12/gal for 7 days. Near-term market impact is negligible; refiners PSX, VLO, and MPC are structurally short this policy if it advanced. Current stock prices show strong 7-day rallies (PSX +8.33%, VLO +6.74%, MPC +9.75%) unrelated to this bill.
→ If triggered, domestic gasoline supply would increase by the volume previously exported, reducing domestic wholesale prices and compressing refining margins. Phillips 66 exported ~25% of its gasoline production in recent years; an export ban would redirect that volume into the domestic market.
The FENCES Act (HR6409) was reported by the House Energy and Commerce Committee on 2026-04-09 and placed on the Union Calendar, advancing toward a floor vote. It provides regulatory relief to states and industries in Severe/Extreme ozone and Serious PM nonattainment areas by exempting them from EPA sanctions if they demonstrate transboundary emissions cause nonattainment. The bill authorizes no direct funding but removes a compliance cost liability for utilities and refiners in affected states, with immediate beneficiaries being companies with assets in Texas, Louisiana, and the Carolinas.
→ States with refinery clusters in Texas, Louisiana, and California are relieved from imposing EPA penalty fees and implementation plan sanctions on industrial sources if the state demonstrates transboundary emissions cause the nonattainment. This reduces compliance cost liability for refineries in those states.
S. 3390 is an early-stage procedural bill requiring a DNI report and Treasury determination on Chinese-Iranian oil and ballistic missile transactions. It authorizes zero funding, has no direct market mechanism, and faces a long legislative path with no near-term impact on any publicly traded company.
HR8228, an early-stage House bill to nullify Presidential Proclamation 11012's temporary import surcharge, would materially reduce input costs for major retailers and energy companies if enacted. The bill mandates retroactive refunds of surcharges collected since February 20, 2026, creating potential for significant cash refunds to importers. Market data shows retailers $WMT and $TGT trading near 52-week highs and refiners $PSX and $MPC posting strong 7-day gains, reflecting sector optimism around trade cost relief.
→ Removal of the surcharge on crude oil and petroleum product imports reduces feed costs for domestic refiners, improving downstream margins.
$DOW and $PSX face incremental compliance risk from S.4181 (Plastic Pellet Free Waters Act), which mandates EPA ban all plastic pellet discharge within 60 days. However, the bill is at earliest legislative stage — referred to committee with no funding authorization — so zero near-term market impact. Passage probability is low in 119th Congress.
→ Required capital expenditure for industrial wastewater treatment upgrades, spill containment infrastructure, and pellet capture systems at facilities handling pre-production plastic pellets; potential operational constraints on pellet loading and transport logistics.
HR8079 eliminates ALL federal emissions control requirements for motor vehicles — a complete repeal of Title II Clean Air Act rules on aftertreatment, diagnostic systems, and diesel fuel sulfur. The bill structurally destroys demand for aftertreatment component suppliers like Dana ($DAN) while drastically lowering cost bases for truck manufacturers (PACCAR) and refiners (ExxonMobil, Chevron, Phillips 66, Marathon Petroleum). This is early-stage legislation with zero earmarked funding, but its mechanism — absolute prohibition on enforcement — is a direct financial transfer from the emissions control supply chain to truck OEMs and fuel producers.
→ Removal of RIN (RFS) and ULSD compliance costs; Phillips 66’s clean fuel program costs could decline by $200M–$400M annually. Refining margin per barrel of diesel increases $0.50–$1.50.
The American Petroleum First Act (HR8021), introduced March 19, 2026, exempts certain vessels from Jones Act restrictions for domestic crude and petroleum product transport, lowering marine costs for refiners and producers. Real market data shows a strong 7-day recovery in energy stocks, led by independent refiners MPC (+9.52%), PSX (+8.42%), and VLO (+6.48%), reversing sharp 30-day pullbacks in majors (XOM -8.7%, CVX -6.65%). Bill is early-stage but represents a clear regulatory catalyst for domestic oil logistics cost relief.
→ Lower marine transport costs by allowing lease of foreign-flagged, lower-cost vessels; eliminates reliance on high-cost U.S.-flagged, U.S.-built, U.S.-crewed Jones Act fleet
HR 7960 (Big Oil Windfall Profits Tax Act) is an early-stage bill referred to committee with low passage probability. It introduces headline risk to the energy sector but has no near-term financial impact. Real market data shows a broad 7-day rally across the sector (XOM +3.79%, CVX +4.1%, MPC +8.82%) despite a mixed 30-day trend, indicating that investors are not pricing in this legislative risk.
→ If Brent crude oil average price in a calendar quarter exceeds the 2025 annual average (plus inflation adjustment), the excess multiplied by 50% becomes a per-barrel tax liability
The Big Oil Windfall Profits Tax Act (S4111) imposes a 50% excise tax on crude oil profits above a 2025 baseline, directly targeting U.S. producers (XOM, CVX, EOG, OXY) and refiners/importers (MPC, PSX, VLO). The bill is in early committee stage with 12 Democratic cosponsors and a companion in the House, indicating partisan momentum but a long legislative path. Despite recent 7-day rallies in oil stocks (XOM +3.7%, MPC +8.74%), the bill signals a clear policy risk to upstream margins and refining costs.
→ Imposes a direct tax on imported crude volumes, increasing raw material costs for refiners that depend on foreign oil.
HR161 (New Source Review Permitting Improvement Act) reported out of House Energy & Commerce Committee on April 28, 2026. Refiners ($MPC, $PSX) and chemical companies ($LYB, $DOW) show strong 7-day gains of +9.37% and +8.75% respectively, reflecting market pricing of regulatory relief. The bill redefines NSR 'modification' to require a 10-year peak-hourly baseline and exempts reliability/safety projects, directly lowering compliance costs for heavy industry.
→ Phillips 66 can accelerate FCC (fluid catalytic cracking) unit maintenance and coker projects without triggering NSR reviews. The bill also benefits their chemical joint venture by exempting catalyst changes and process optimizations from 'modification' designation.
HR1422 (Enhanced Iran Sanctions Act) passed the House on March 16, 2026, and is now pending in the Senate. If enacted, mandatory sanctions on Iranian petroleum transactions will tighten global crude supply by 0.5-1.5 million bpd, boosting prices and margins for U.S. oil producers ($XOM, $CVX), independent refiners ($MPC, $PSX, $VLO), and crude tanker owners ($FRO, $DHT). Recent market data shows energy stocks already pricing in supply disruption risk, with refiners and tanker stocks posting strong 7-day gains of 2.7-9.4%.
→ Reduction in global heavy-sour crude supply tightens the market, widening the differential between WTI-linked domestic crude and Brent-linked product prices. U.S. refiners benefit from lower relative feedstock costs.
