Announcing the measure, bank governor Miguel Angel Fernandez Ordonez said that examinations had already taken place on banks, savings banks and credit co-operatives, with checks attempting to ensure that the firms have sufficient capital available for now and the future.
He said making the results of the stress tests public will have several consequences, reports AP.
"[It will] reveal the deterioration estimated, the consequent capital requirements and the capital funding committed [and] provide the markets with a perfectly clear idea of the situation of the Spanish banking system," the official explained.
Earlier this week, Deutsche Bank chief executive officer Josef Ackermann warned that publishing stress test results could increase market instability unless support mechanisms were put into place.
