Buying insurance through the government program known as COBRA would temporarily become a lot cheaper. COBRA, for the Consolidated Omnibus Budget Reconciliation Act, generally lets someone who loses a job buy coverage via the former employer. But it’s expensive: Under normal circumstances, a person may have to pay at least 102 percent of the cost of the premium. Under the relief bill, the government would pay the entire COBRA premium from April 1 through Sept. 30. A person who qualified for new, employer-based health insurance someplace else before Sept. 30 would lose eligibility for the no-cost coverage. And someone who left a job voluntarily would not be eligible, either.

This credit, which helps working families offset the cost of care for children under 13 and other dependents, would be significantly expanded for a single year. More people would be eligible, and many recipients would get a bigger break. The bill would also make the credit fully refundable, which means you could collect the money as a refund even if your tax bill was zero. “That will be helpful to people at the lower end” of the income scale, said Mark Luscombe, principal federal tax analyst at Wolters Kluwer Tax & Accounting. .

There would be a big one for people who already have debt. You wouldn’t have to pay income taxes on forgiven debt if you qualify for loan forgiveness or cancellation — for example, if you’ve been in an income-driven repayment plan for the requisite number of years, if your school defrauded you or if Congress or the president wipes away $10,000 of debt for large numbers of people. This would be the case for debt forgiven between Jan. 1, 2021, and the end of 2025. .

The bill would provide billions of dollars in rental and utility assistance to people who are struggling and in danger of being evicted from their homes. About $27 billion would go toward emergency rental assistance. The vast majority of it would replenish the so-called Coronavirus Relief Fund, created by the CARES Act and distributed through state, local and tribal governments, according to the National Low Income Housing Coalition. That’s on top of the $25 billion in assistance provided by the relief package passed in December. To receive financial assistance — which could be used for rent, utilities and other housing expenses — households would have to meet several conditions. Household income could not exceed 80 percent of the area median income, at least one household member must be at risk of homelessness or housing instability, and individuals would have to qualify for unemployment benefits or have experienced financial hardship (directly or indirectly) because of the pandemic. Assistance could be provided for up to 18 months, according to the National Low Income Housing Coalition. Lower-income families that have been unemployed for three months or more would be given priority for assistance. .

“While the economic fallout has been real and widespread, the worst was avoided by swift and vigorous action,” he said.

Mr. Powell and Ms. Yellen faced a volley of questions on how financial regulators should deal with climate change risks. Republicans have expressed concern that the Fed’s growing attention to climate-related issues in its role as a bank overseer could end up making it harder or more expensive for carbon-heavy companies to get loans.

“It’s really very early days in trying to understand what all of this means,” Mr. Powell said, noting that many large banks and large industrial companies were already thinking about and beginning to disclose how climate might affect them over time. “We have a job,” he said, “which is to ensure that the institutions we regulate are resilient to the risks that they’re running.”

Financial Stability Climate Committee “to identify, assess and address” climate-related risks to financial stability.

The new body will approach its task in a way that “considers the potential for complex interactions across the financial system,” Ms. Brainard said, rather than just the risks to individual companies.

That’s the kind of oversight some lawmakers fear.

“Linking hypothetical climate scenarios to risks to the entire financial system seems to me highly speculative,” Representative Andy Barr, a Republican from Kentucky, told Mr. Powell and Ms. Yellen during the Tuesday hearing.
