Profit reached 203.2 billion yen ($1.85 billion) for the three months through June, versus 86.1 billion yen in the same period a year earlier, Japan's second-largest lender by assets said in a filing to the stock exchange.
For the full year through March, SMFG reiterated its forecast for profit of 600 billion yen. That compared with the 646.4 billion yen average of 10 analyst estimates compiled by Refinitiv.
Japanese banks have been struggling with years of ultra-low interest rates and a shrinking population, and in the last financial year, major banks including SMFG saw a surge in credit-related costs because of the pandemic.
SMFG's credit-related costs dropped to 10.3 billion yen in the first quarter of the financial year started April, compared with 114.8 billion yen a year earlier.
The lender has estimated such costs will reach 300 billion yen in the current financial year.
While credit-related costs have pressured the bank's profit, its interest income has increased as corporate clients rushed to borrow to survive the pandemic slowdown. Japanese bank lending rose 1.4% in June from a year prior, Bank of Japan data showed.
SMFG's net interest income at its banking arm was 235.9 billion yen for the first quarter, a 12.5% on-year rise.
Bigger peer Mitsubishi UFJ Financial Group Inc is scheduled to announce first-quarter earnings on Monday.
