The past 150 days have been momentous for the financial policy world. Congress has been at the center of much of the action.

Lawmakers are working overtime to incorporate crypto into the regulated financial system. The U.S. housing affordability crisis looms. President Donald Trump’s trade wars are bending the economy in ways policymakers are just beginning to understand. And stock and bond markets have been bouncing around like an EKG.

All this financial policy action comes as key congressional panels have new leaders. So let’s take a second to check in with four lawmakers who are defining the Trump administration’s finance agenda, either through support or opposition.

Sen. Tim Scott (R-S.C.): The Senate Banking Committee chair had a good spring. It remains to be seen whether the summer will be as kind.

Scott’s panel advanced the GENIUS Act to regulate the stablecoin market in March, and the bill passed the Senate on Tuesday with 18 Democrats. This is the first time the Senate has ever advanced crypto legislation. Banking has also quickly advanced several critical financial policy nominees — though a few prominent ones have struggled to get floor time.

Everything coming next will be tougher. It’s not clear how the House will proceed on GENIUS, given its own approach. Scott has faced open skepticism from GOP members about his panel’s section of the party’s reconciliation package, which tries to eliminate funding for the Consumer Financial Protection Bureau. The committee has barely touched crypto market structure reform, giving the House’s product a legislative edge.

Sen. Elizabeth Warren (D-Mass.): The ranking member of the Senate Banking Committee has had a weird season so far.

The headlines haven’t been pretty for the Massachusetts progressive. Warren fought hard against the GENIUS Act, arguing the bill would crack open the payments system for commercial giants, imperil community banks and further enrich Trump. For her trouble, more than half the Democrats on the Banking panel voted for the stablecoin bill on the floor.

Warren has also been denied some key personnel victories. The White House isn’t planning to fill Democratic spots on bipartisan agency boards, such as at the Securities and Exchange Commission, which would have been a golden opportunity for Warren to install future financial policy leaders from her orbit.

But it hasn’t been a wash. There’s no question that pressure from Warren and other Democrats shaped key additions to the final version of GENIUS. Warren has found pockets of bipartisanship, including with Sen. Jim Banks (R-Ind.) on national security concerns around Nvidia and even with Trump on getting rid of the U.S. debt limit. And the Banking Committee is expected to host a bipartisan housing markup as soon as next month.

Rep. French Hill (R-Ark.): The House Financial Services Committee chair is in a strong position heading into the summer and fall.

Hill’s committee is a pocket of discipline in an otherwise unwieldy House. The panel has been cranking through legislation all year long, hosting six days’ worth of markups since January. That includes high-profile crypto bills, reconciliation instructions and a flurry of changes to bank supervision.

The Senate has outrun the House on stablecoin legislation. But Hill holds significant leverage on the second half of the crypto sector’s legislative agenda after lawmakers advanced a bill that would set the rules of the road for crypto markets through both the House Agriculture and Financial Services committees.

The crypto sector is more than a little worried that Congress won’t enact both halves of its agenda this session. Right now, Hill’s got two bills in hand to the Senate’s one. If we’re gonna see One Big Beautiful Crypto bill, chances are it will appear in the House.

Rep. Maxine Waters (D-Calif.): Like Warren, Waters has mostly struck out on crypto legislation this year. The California Democrat has been flatly opposed to the digital asset bills coming out of the House Financial Services Committee, but that hasn’t stopped some of her members from backing these efforts.

But we’ll say this much about the former Democratic chair of Financial Services: She has made Republicans fight for every inch of every markup held this year. Waters has forced marathon, 10-hour-plus markups several times this year, including a 13-hour markup of the STABLE Act in April. Regardless, policy-wise, the effect has been muted.
