Climate activists are starting to map out a coordinated campaign to oppose the potential renomination of Federal Reserve Chair Jerome Powell, because they view his record on fighting climate change through the banking system as scant and not aggressive enough.

The Federal Financial Institutions Examination Council says bank accounts and information systems have become more vulnerable as mobile and other technologies have expanded. It issued guidelines on detailed steps financial institutions should take to heighten security.

This year’s stress tests examined 23 banks including JPMorgan Chase and Goldman Sachs, with the remainder of the firms on an “every other year” test cycle. The capital requirements for those remaining firms are unchanged from last year.

A problem caused by the pandemic appeared to be resolved, but has returned in recent months. Here’s what happened.

As the Federal Reserve mulls the idea of issuing a digital currency, some industry representatives are already sounding the alarm. Their main concern is a new regime for storing cash will reduce demand for bank deposits.

Sen. Patrick Toomey, the ranking Republican on the Banking Committee, has argued that research by the Federal Reserve into these topics could result in “mission creep.” Fed officials have said their job includes fostering inclusive economic growth and ensuring the banking system is girded against financial risks posed by climate change.

Sen. Elizabeth Warren praised Federal Reserve Gov. Lael Brainard on Wednesday for her approach to financial regulation while criticizing Chairman Jerome Powell as too protective of big financial institutions.

The industry had tightened up last year in the face of COVID-19. But as the economic outlook improves, banks are now easing criteria amid heightened competition, according to the Federal Reserve’s survey of loan officers.

The smallest U.S. businesses — those with no employees other than the owner — struggled during the past year with 76% of the firms suffering a decline in revenue over 12 months, a new survey by regional Federal Reserve banks found.

The Office of the Comptroller of the Currency’s pledge to rescind Trump-era Community Reinvestment Act reforms and work with other regulators suggests that an interagency agreement is within reach. But outstanding issues remain, particularly around the treatment of online banking activities.

While money market funds are flocking to the Federal Reserve’s overnight reverse repurchase agreement facility for the yield, large U.S. banks are using the program to shed unwanted deposits.

Sens. Sherrod Brown and Elizabeth Warren criticized Federal Reserve Chair Jerome Powell over reg relief policies instituted by the central bank, signaling that some progressive lawmakers may be reluctant to give him a second term.

As the Federal Reserve mulls whether to establish its own digital currency, Chair Jerome Powell told lawmakers that cryptocurrencies designed to have the stability of bank deposits and money market funds should be regulated accordingly.

Fiscal restraint, the reversal of enormous amounts of monetary stimulus, smarter regulation and job retraining are among the public policy steps that could interrupt the long U.S. tradition of boom-and-bust cycles.

The president has a chance to make his mark on the central bank as the terms of Federal Reserve Chair Jerome Powell and Vice Chair of Supervision Randal Quarles near their end. He will face pressure from progressives to pick reform-minded leaders, while moderate Democrats and Republicans in the narrowly divided Senate might favor reappointing Powell.

Fintech companies with narrow-purpose banking charters pose a safety-and-soundness risk and should be denied access to the payment system and other perks unless they meet the same strict regulatory criteria as traditional financial institutions, trade groups for banks and credit unions told the Federal Reserve.

Edward Al-Hussainy, senior interest rate and currency analyst at Columbia Threadneedle, will discuss the economy, inflation and the Federal Reserve.

Fed Vice Chairman for Supervision Randal Quarles says the benefits of a central bank digital currency are “unclear,” and that a digital dollar could actually “pose significant and concrete risks.”

Some of the 23 large banks that participated in last week’s stress tests will be better positioned to reward shareholders than others, since they padded their capital amid the pandemic. Still, all are expected to tread cautiously amid ongoing economic uncertainty.

The Federal Reserve found that under its harshest stress-test scenario, bank capital ratios would decline to 10.6% on average — well above the 4.5% minimum requirement. Restrictions imposed on dividend payments and share repurchases during the economic crisis last year will be lifted after June 30.
