China's biggest commercial banks managed to eke out small increases in profit for 2020, with a sharp turnaround in their fortunes during the year mirroring the country's rapid economic rebound from the coronavirus pandemic.

For all of 2020, China's four largest banks reported that annual net profit rose between 1.2% to 2.9%, according to filings released Tuesday and late last week. China was the only major world economy to grow last year, expanding by 2.3%.

The quartet -- Industrial and Commercial Bank of China Ltd., China Construction Bank Corp., Agricultural Bank of China Ltd. and Bank of China Ltd. -- together account for more than one-third of the industry's total assets.

At Industrial and Commercial Bank of China, net profit grew 1.2% year-over-year to 315.9 billion yuan, the equivalent of $48.1 billion. The giant lender is the world's biggest bank by assets, according to an April 2020 ranking by S&P Global Market Intelligence.

The modest increase in annual earnings masked a turbulent year, with earnings jumping 44% year-over-year in the last three months of 2020. It was a similar story at the other big banks.

To combat the economic effects of the pandemic, Beijing slashed benchmark lending rates, stepped up government spending and ordered banks to offer cheap loans to support businesses and households. First-half profits fell by more than 10% at all of the big four banks, as they took large provisions against potential bad loans.

In the last sixth months of the year, as an economic recovery gathered steam, businesses recovered. Meanwhile the central bank tolerated rising money-market rates. These help determine the levels at which banks lend to their customers.

"Covid was under control for the second half of the year," said Harry Hu, senior director at S&P Global Ratings in Hong Kong. That meant corporate cash flows improved as people and businesses grew less pessimistic, he said, leading to a slowdown in loans turning sour.

Likewise, Shujin Chen, a banking analyst at Jefferies, said new bad loans declined after peaking in the second quarter, allowing banks to set aside fewer provisions. At the same time, she said banks were able to increase their net-interest margins, a key measure of bank profitability, after previously having to "forgo profit to bolster the real economy." Ms. Chen said these two tailwinds meant the banks had a good chance of growing earnings by double-digit percentages in 2021.

Interest margins rose in the second half, but still lag pre-pandemic levels. At China Construction Bank, for instance, the net-interest margin rose to 2.19% for the whole year, up from 2.14% at the half-year point. In 2019 the margin stood at 2.32%.

For the whole year, the ratio of nonperforming loans to total assets at the big four banks edged up versus 2019.

Across the banking sector, net profit declined by 2.7% in 2020, official figures show. That indicates smaller lenders face tougher conditions than the big four, but shows the entire sector is recovering, after registering a 9.4% drop in the first half of the year.
