House Republicans, who are critical of many provisions in Dodd-Frank, have been seeking to use funding cuts as a way to starve regulators of resources and slow down the implementation of the law.
More recently, the CFTC has also come under fire for its oversight of the collapsed brokerage MF Global.
While the CFTC has borne the brunt of Republican efforts to slash funding, the SEC has managed each year since the crisis to win spending increases.
That may be due in part to the fact that the agency's budget is offset by industry transaction fees, and does not contribute to the U.S. deficit.
The appropriations subcommittees that oversee the SEC and CFTC will consider the spending bills on Wednesday.
In addition to the proposed budgets for the SEC and CFTC, the House Appropriations Committee is also proposing to change the funding structure for the newly-created Consumer Financial Protection Bureau.
Under the plan, the CFPB would no longer be funded by the Federal Reserve, and instead would have its budget appropriated by Congress starting in 2014.
Critics of the new CFPB, which was created by the Dodd-Frank law to protect consumers from unfair credit-card practices and predatory lending, have complained the bureau should be more directly accountable to Congress.
