Judging by the trace, there are 300K accounts in DEPOSIT_ACCOUNT_INT_OPTION, DEPOSIT_ACCOUNT and ACCOUNT, but only 500 in DEPOSIT_ACCOUNT_SUMMARY. This type of mis-match is not something Oracle anticipates very well. You could drive off DEPOSIT_ACCOUNT_SUMMARY and nested loops join to the other tables. That way you would avoid reading most of the 300K unmatched rows in 3 tables. The SQL may need hints though.
You will need indexes on
ACCOUNT.ACCT_ID
DEPOSIT_ACCOUNT.ACCT_ID
DEPOSIT_ACCOUNT.DEPOSIT_ACCT_ID
DEPOSIT_ACCOUNT_INT_OPTION.DEPOSIT_ACCT_ID
Make sure you have these indexes in place, and change the beginning of your SQL to:
SELECT /*+ LEADING(DPAS) USE_NL(DPIO) USE_NL(DPA) USE_NL(A) */
A.REC_ST,
DPAS.VERSION_NO,
...
Try with just the LEADING hint first. Add the USE_NL hints if it continues to perform hash joins. If that doesn't work, add INDEX hints for each of DPIO, DPA and A as well.

Ummm ... there are 500 rows in the table, you are using all 500 of them. What type of index were you hoping to use that would speed up the read of every single row in the table?
More to the point: is it faster?
