Profits at Goldman Sachs jumped amid a merger boom, while JPMorgan Chase's results were boosted by the impact of the recovering economy on loan quality, according to results released Tuesday.

The financial heavyweights reported soaring second-quarter profits compared with the year-ago period when large banks set aside massive reserves in case clients defaulted amid the coronavirus downturn.

But widespread access to Covid-19 vaccines and the accelerating reopening of the US economy have put those days in the rearview mirror.

At JPMorgan, which has a significant retail operation in addition to investment banking, combined debit and credit card spending was up 45 percent from the year-ago level and more than one-fifth higher than in the pre-pandemic 2019's second quarter, said Chief Executive Jamie Dimon.

He highlighted "exceptionally strong" consumer and business balance sheets.

The much sunnier outlook, however, includes some continued question marks surrounding the course of the pandemic.

The rapid spread of the Delta variant of Covid-19 is one factor creating "elevated uncertainty" about the bank's outlook for "a very robust recovery," said JPMorgan Chief Financial Officer Jeremy Barnum.

And Goldman Sachs Chief Executive David Solomon also cited the pandemic as a potential source of economic trouble, noting recent restrictions in Hong Kong and Australia.

Vaccine pickup "is not consistent across communities and nations, including parts of the United States," Solomon said on a conference call with analysts. "Widespread vaccine distribution and high vaccine rates are critical to open and thriving economies."

The biggest US bank by assets, JPMorgan kicked off the earnings season for the sector, reporting that profits more than doubled to $11.9 billion in the latest quarter, including a boost from $3 billion that had been set aside as reserves.

JPMorgan had budgeted $8.9 billion for bad loans in the year-ago period, but it reported just $734 million in charge-offs for defaults in the second quarter.

But revenues for the period fell eight percent to $30.5 billion, as the bank's trading business saw much less activity compared with the year-ago level.

Bank executives also expressed little optimism about loan growth, given the healthy state of US consumer finances following government stimulus programs.

Loan growth is going to be "a little bit of a slog through the rest of this year," Barnum told reporters.

While "unusually high" pay rates for credit cards are "a healthy thing for consumers," he said "it does create a bit of a headwind for our loan growth."

JPMorgan scored record global investment banking fees of $3.6 billion during the quarter, driven by heavy merger and acquisition activity.

At Goldman, profits came in at $5.3 billion in the second quarter, compared to just $197 million a year earlier, a when results were dented not only by provisions for bad loans, but from elevated legal costs.

Revenues were $15.4 billion, a 16 percent increase and the second highest quarterly revenues in the firm's history after the first three months of 2021.

Goldman's results reflected a jump in financial advisory revenues due to a rise in completed mergers and acquisitions. The backlog of additional deals also "increased significantly compared with the end of 2020."

However, Goldman also saw a steep drop in markets revenue on lower volatility compared with the same period of last year.

Solomon said the strong performance reflected a "constructive but more normalized market environment.:

He expressed measured concern about rising prices, noting Goldman economists' views that "inflationary pressures might be transitory," in which case "any resulting risks could be adequately managed."

Goldman announced a boost in its quarterly dividend to $2 per share from the prior $1.25.

Shares of JPMorgan fell 1.5 percent to $155.65 while Goldman fell 1.2 percent to $375.98.

Both banks have seen share prices rise in 2021 on Wall Street, JPMorgan by more than 20 percent and Goldman by more than 40 percent.
