If you have 1,000 pesos today and you intent to use it for food after one year, then don't deposit it on bank. Your money will decrease its purchasing power and the interest given to you by your bank is not enough to compensate its lost.
Today, I just purchased a canned sardines and immediately I ate. While eating I asked myself, "What if I had purchase this canned sardines one year earlier then I should have save a lot."
If I have 1,000 pesos today then I am going to buy canned goods in wholesale price. Of course, taking into consideration the storage life span or expiration of canned goods. Canned goods increases in price every time there is a calamity or a disaster. Their prices goes up and never comes down.
