Sheria ya Benki Kuu ya Tanzania ya mwaka 2006 inatoa mamlaka kwa Benki Kuu pekee kutengeneza na kutoa fedha (noti na sarafu) kwa matumizi nchini Tanzania. Hiyo ndiyo fedha halali kwa ajili ya malipo nchini Tanzania. Hivyo, Benki Kuu ina wajibu wa kubuni na kuagiza noti na sarafu ili kukidhi mahitaji ya fedha nchini. Fedha ya Tanzania ni Shilingi, ambayo imegawanywa kwenye senti 100. Benki Kuu inahakikisha kwamba sarafu yake ni ubora unaokubalika kwa sarafu nzuri ambao ni; :

• Kukubalika na umma kama fedha kwa ajili ya kufanya malipo ya bidhaa na huduma;
• Alama za usalama ambazo zinafanya iwe vigumu kutengeneza noti na sarafu zisizo halali;
• Uwezo wa sarafu kudumu kwa muda mrefu.

Ili kutekeleza na kuhakikisha kwamba hali inakuwa hivyo, Benki inatekeleza Sera ya Fedha Safi ambayo inatoa elimu kwa umma kupitia programu mbalimbali, zikiwemo ushiriki katika maonesho ya biashara ya kimataifa ya Dar es Salaam (Saba Saba) na Kilimo (Nane Nane).
