delivered the opinion of the Court.
In this case we must determine whether federal legislation providing for controls over the allocation and pricing of petroleum products, passed in response to the oil crisis of the early 1970’s, or the legislation subsequently eliminating those controls, pre-empts gasoline price regulation by the Commonwealth of Puerto Rico.
I
In 1973, Congress passed the Emergency Petroleum Allocation Act (EPAA), Pub. L. 93-159, 87 Stat. 627, 15 U. S. C. § 751 et seq., in reaction to severe market disruptions caused by an embargo on oil exports to the United States. The central provision of the legislation, upon which all the rest depended, was § 4, 15 U. S. C. § 753, which required the President to promulgate regulations governing allocation and pricing of petroleum products. The Act also contained an express pre-emption provision, § 6(b), 15 U. S. C. § 755(b), precluding state and local regulation of allocation and pricing in conflict with a regulation or order under § 4. * As origi *498 nally enacted, the EPAA provided for termination of the President’s regulatory authority early in 1975, but during that year Congress provided for temporary extensions, and then enacted the Energy Policy and Conservation Act (EPCA), Pub. L. 94-163, 89 Stat. 871 (codified in scattered Titles and sections of United States Code), which amended the EPAA to provide for gradual decontrol. The EPCA extended the President’s EPAA regulatory obligations for 40 months, and thereafter granted him discretionary regulatory authority until September 30, 1981; on that date, the statute prescribed that “[t]he authority to promulgate and amend any regulation or to issue any o'rder under [the EPAA] shall expire.” § 461, 89 Stat. 955, 15 U. S. C. § 760g.
Before enactment of the EPAA, Puerto Rico had regulated the prices of gasoline and other petroleum products sold in the Commonwealth. The Puerto Rico Department of Consumer Affairs (referred to in this litigation as DACO, apparently the acronym of its Spanish title, Departamento de Asuntos del Consumidor) was charged with regulating these and other commodities, but suspended its regulation of petroleum products when the EPAA was passed in 1973. In 1975, anticipating the expiration of the EPAA, DACO issued a regulation to restore its regulatory authority, but after the EPCA was passed it modified this regulation to make it effective only after federal price controls were lifted. Then in the spring of 1986 (414 years after the President’s regulatory authority was terminated), the Legislature of Puerto Rico imposed an excise tax on oil refiners, and DACO issued the regulations that are the subject of the challenge here. DACO Orders of March 26, April 23, and May 20, 1986 (App. to Pet. for Cert. 42a-45a, App. 7-12, 21-29). Among other requirements, these regulations prescribed that the Secretary of DACO be given 15 days’ notice of price increases, pro *499 hibited wholesalers from passing on the cost of the excise tax to retailers, and imposed maximum profit margins on sales by wholesalers to retailers. '
Respondents, several oil companies, brought actions that were consolidated in the United States District Court for the District of Puerto Rico alleging,
inter alia,
that DACO’s orders were unconstitutional on pre-emption grounds, and requesting declaratory and injunctive relief. The District Court enjoined DACO from enforcing its regulations, in part on the grounds that DACO’s authority was pre-empted by Congress’ decision to decontrol petroleum prices, and petitioners appealed this determination to the Temporary Emergency Court of Appeals (TECA). (Petitioners also challenged certain other aspects of the District Court’s decision in an appeal to the United States Court of Appeals for the First Circuit, which has stayed its proceedings.) A divided panel of the TECA affirmed.
II
Although Puerto Rico has a unique status in our federal system, see,
e. g., Examining Board
v.
Flores de Otero,
We have suggested elsewhere that the Constitution permits congressional creation of such a regime. See,
e. g., Arkansas Electric Cooperative Corp.
v.
Arkansas Public Service Comm’n,
In the last analysis, what respondents rely upon consists of nothing more than excerpts from the legislative history of the EPCA which in their view (though not in the view of petitioners) evidence a congressional intent that there be a free market in petroleum products. While we have frequently said that pre-emption analysis requires ascertaining congressional intent, see, e. g., Louisiana Public Service Comm’n, supra, at 369, we have never meant that to signify congressional intent in a vacuum, unrelated to the giving of meaning to an enacted statutory text. There is no text here — neither §6(b), which only pre-empts conflicts with actual federal regulation, nor any extant federal regulation that might plausibly be thought to imply exclusivity — to which expressions of pre-emptive intent in legislative history might attach. Respondents have brought to our attention statements that may reflect general congressional approval of a free market in petroleum products, or general congressional belief that such a market would result from enactment of the EPCA, or even general congressional desire that it result. But unenacted approvals, beliefs, and desires are not laws. Without a text that can, in light of those statements, plausibly be interpreted as prescribing federal pre-emption it is impossible to find that a free market was mandated by federal law.
Today’s conclusion that the DACO regulations are not preempted was plainly foreshadowed by our decision in
Tully
v.
Mobil Oil Corp.,
Instead of following our decision in
Tully,
the TECA relied on language in our subsequent decision in
Transcontinental Pipe Line Corp.
v.
State Oil and Gas Bd. of Miss.,
At one point in our Transcontinental opinion, we phrased the question as “whether Congress, in revising a comprehensive federal regulatory scheme to give market forces a more significant role in determining the supply, the demand, and *503 the price of natural gas, intended to give the States the power it had denied FERC.” Id., at 422. In the decision below, the TECA apparently interpreted this as the enunciation of a new pre-emption test, and proceeded to search the legislative history of the EPCA for evidence of an affirmative intention that the States assume the price-regulating role that the Federal Government was abandoning. Finding none, and further finding the expression of congressional sentiments favoring the free market, it concluded that the States were pre-empted. This mistook our intent. Transcontinental was not meant to announce a new rule of burden-shifting whenever the Federal Government terminates or reduces its regulation of a field of commerce, replacing the normal need for finding a federal intent to pre-empt with a need to find a federal intent to retransfer authority to the States. To the contrary, a “clear and manifest purpose” of pre-emption is always required. We demanded an affirmative intent to retransfer authority in Transcontinental because only that could have refuted the pre-emptive intent already manifest in the revised, but nonetheless “comprehensive,” federal regulatory scheme.
Respondents would draw exaggerated inferences from another statement in
Transcontinental,
to the effect that “ ‘[a] federal decision to forgo regulation in a given area may imply an authoritative federal determination that the area is best left unregulated, and in that event would have as much preemptive force as a decision
to
regulate.’ ”
Ibid.,
quoting
Arkansas Electric Cooperative Corp.,
*504 That is not what we have here. Congress has withdrawn from all substantial involvement in petroleum allocation and price regulation. There being no extant action that can create an inference of pre-emption in an unregulated segment of an otherwise regulated field, pre-emption, if it is intended, must be explicitly stated. To adopt the imaginative analogy set forth in the Solicitor General’s amicus brief, repeal of EPAA regulation did not leave behind a pre-emptive grin without a statutory cat.
For the reasons stated, the judgment of the TECA is
Reversed.
Notes
Specifically, § 6(b), as codified, 15 U. S. C. § 755(b), read as follows:
“The regulation under [§ 4] of this title and any order issued thereunder shall preempt any provision of any program for the allocation of crude oil, residual fuel oil, or any refined petroleum product established by any State or local government if such provision is in conflict with such regulation or any such order.”
This text permits the argument that the federal pre-emption excluded state and local price regulation only in connection with a state or local allocation program. That argument has not been made here, and would in any event only reinforce the conclusion that we reach. We shall assume, for *498 purposes of our analysis, that the federal pre-emption of conflicting price regulation was complete.
