Iron Bank of Braavos
According to Matthar, the Iron Bank was founded by twenty three Braavosi: sixteen men and seven women, each of whom owned a key to the bank's great subterranean vaults. Their descendants, now numbering more than one thousand, are known as "keyholders" and proudly display their keys on formal occasions, though these keys are entirely ceremonial. Certain of these founding families have declined, with some losing their wealth entirely, yet all of them they cling to their keys and the honors that go along with them.
However, the Iron Bank is not ruled by the keyholders alone. Some of the wealthiest and most powerful Braavosi families of today are rather younger, yet their heads own shares in the bank, sit on its secret councils, and have a voice in selecting the men who lead it.
Though all the Free Cities have their own banks, the Iron Bank is richer and more powerful than all the others combined and has a fearsome reputation when collecting debts. When princes or kings default on their debts or are foolish enough not to honor their agreements with the Iron Bank, the Iron Bank supports new princes and kings to appear. These new princes and kings then honor the previous debt along with paying back the money the bank loaned them in claiming their new power, lest they suffer the same fate as their predecessors. There is a common saying among the Braavosi...

A Game of Thrones
A Clash of Kings
Bronn informs Tyrion Lannister that a moneylender from Braavos has come to the city and requests to see the King for payment on some loans. Tyrion tells Bronn to send the moneylender to Littlefinger to keep him busy.
A Feast for Crows
Queen Cersei and the small council decides to defer payments on the loans they have from the Iron Bank. Pycelle is the only one who objects and tries to warn her of the problems it will cause, but Cersei rejects his advice. In response to the Iron Throne's decision, the Iron Bank begins calling in outstanding debts from all over the Seven Kingdoms and refusing all new loans, causing economic chaos throughout Westeros. Noho Dimittis was sent by the Bank to the Iron Throne to collect the debt, and was told by Queen Cersei at an audience that the Iron Bank would only get its money when the rebellions were quashed.
A Dance with Dragons
Tycho Nestoris, an envoy from the Iron Bank, arrives at the Wall via Eastwatch-by-the-Sea. The Iron Bank plans to help Stannis Baratheon's claim on the condition that he honors the debts the Iron Throne owes the Bank. While present at Castle Black, Jon Snow makes arrangements with the envoy to borrow from the Iron Bank so the Night's Watch can buy food and supplies to see them through the approaching winter. Nestoris travels to Deepwood Motte, where he pays a ransom for the Ironmen which Lady Sybelle Glover accepts for the king. He travels through the snow to Winterfell looking for Stannis. Stannis is not there, but he finds Mors Umber outside the gates with some young boys. Nestoris also takes Theon Greyjoy and Jeyne Poole, who were found by Umber after their escape from Winterfell. After three days they arrive at Stannis's camp in a village.
Ser Harys Swyft, the Master of Coin under Lord Regent Kevan Lannister, has written to the banks of both Pentos and Myr in order to gain the crown a new loan so they can placate the Iron Bank of Braavos, so far however he has been unsuccessful. Before his death, Lord Kevan suggests Ser Harys travel to Braavos and treat with the bank in person.
The Winds of Winter
Tycho and Stannis meet and sign a contract.
Ser Justin Massey has been ordered to escort Tycho safely back to the Wall and from there sail to Braavos with him and use the new found wealth of the Iron Bank to hire sellsword companies for Stannis's cause.
