Yamatai Stock Exchange

The Yamarai Stock Exchange (YSE), also known as the Kyoto Exchange Index (KEI) after the city in which the headquarters are based, is a national stock exchange program designed to bring together the biggest corporations and companies into a singular stock market meant to streamline the sales of shares, coordinate dividends, and allow for investors to conduct business on a shared market throughout the Yamatai Star Empire.

Established YE 40 (Predecessor YE 25)
Employees ~4,000 in office, 2,000 dispersed
Associated Factions Yamatai Star Empire
Headquarters Imperial Stock Exchange, Kyoto, Planet Yamatai
Director Abu Habichi
Nomenclature ID YSE, KEI
Nickname Kyoto Stock Exchange


In YE 25, when Kyoto was completed, the Imperial Stock Exchange was built to house the Kyoto Stock Exchange. This exchange acted only on corporations that were headquartered or at least housed on Planet Yamatai. In YE 34, Origin Industries became a member of the Exchange, and with that, more megacorporations joined in, including Tamahagane Corporation, Murasaki Keiretsu, and Ketsurui Zaibatsu.

In YE 38, the exchange officially opened for the entirety of Yamatai, merging with both the Uesureyan and Teisenjou Stock Exchange. It was officially renamed as the Yamatai Stock Exchange, though to this day it is better known by its prior name of Kyoto Stock Exchange and Kyoto Exchange Index. The first day of the exchange was opened personally by Empress Himiko; subsequently, on holidays and after summer and winter recess, the exchange has been opened by one or more prominent members of one of the companies.

The exchange has been directed by the Minkan Abu Habichi since its opening in YE 25. He has two deputies, one for directing the staff on the site of Imperial Stock Exchange and another for the staff dispersed trough so-called 'front offices' - local buildings where the stock exchange can be remotely accessed without being in Kyoto. Although the use of pagers and stockbrokers is widespread, some of these offices are used intensively by local investors to keep a personal eye on their stocks.


The YSE is calculated by the combination of the prices of all shares at one moment, divided by a divisor called the Kyoto Divisor. The divisor remains reliably stable, but is adjusted in the case of stock split or any structural changes in the index to prevent those events from changing the numerical value of the KEI. The divisor has, since the opening of the exchange in YE 25, been more than 1, meaning that the sum of the shares value is larger than the index. A healthy index is situated around the value of 550 KS for the sum of shares value.


The Stock Exchange is led by the Director, also known as the President, who controls the personnel responsible for its operations. Immediately below him is the Chief Operating Officer(COO), who presides over the daily workings of the company and the Board of Supervision, and the Chairman, who presides over the Board of Managers. The Director has a number of deputy supervisors, who make up the Board of Supervision, also known as the Officers Group; aside from the Director and COO, the Board of Supervision consists of:

  • The Head of Finances, also known as Chief Financial Officer (CFO), who directs market policy and fiscal matters for the Exchange.
  • The Head of Security, who controls the flow of transactions and the physical security of the Exchange.
  • The Head of Technology or Chief Technology Officer (CTO), who directs the IT and Tech personnel in maintaining the smooth operation of the electronic part of the Exchange.
  • The Head of Legal Affairs, or Chief Legal Officer (CLO), who directs the juristic matters of the Exchange.
  • The Head of Partnership or Chief Customer Officer (CCO), who directs contact with the enlisted companies and shareholders.

A Head of Personnel Affairs was proposed in YE 38, but its role was ultimately split between the two Personnel Managers.

Below the Board of Supervision is the Board of Managers, who answers to the Director and advises the Heads on the personnel. It is presided over by the Chairman. The Board of Managers consists of:

  • Two Personnel Managers, one for the Imperial Stock Exchange personnel and one for the personnel dispersed throughout Yamatai space.
  • The Press Manager, who handles all news matters for the exchange.
  • The Investment Manager, who presides over corporate investments and risks.
  • The Marketing Manager, who handles the exchange's public face.
  • The Analysis Manager, who is subordinate to the CTO and oversees the analytical process of the exchange
  • The Diversity Manager, who is subordinate to the Personnel Managers and is responsible for diversity and social inclusion in the exchange's personnel.
  • The Administrative/Accounting Manager, who oversees the daily administrations and accounting work of the exchange.

Aside from these, each corporation has the right to appoint a financial advisor to the Director to advise on the conduct between the exchange and their company. As such, Origin Industries and Tamahagane Corporation both have advisors embedded in the exchange, the Yamatai Department of Finance has a financial advisor installed at the exchange to advise on financial law, the National Bank of Yamatai has advisors for concerns on precious metals and other goods, and the Star Army of Yamatai has an emergency advisor - assigned to the Head of Security - in order to prevent any terrorist or hostile attacks. The Star Army's presence has only been needed once thus far: in YE 33 there were indications of Mishhuvurthyar intrusions in the database systems.

Both of the Boards meet on each start and end of the financial week (on Monday and Saturday) to discuss the workings of the Exchange; additionally, the Board of Managers meets on each Thursday - and on each Wednesday there is a Company Meeting, where governmental advisors and representatives from other exchange companies can meet with the Director and both of the Boards. There is also a possibility for an emergency meeting - also called a Big Coalition Meeting - wherein all heads, government advisors, and company representatives meet in the Imperial Stock Exchange. As they're generally reserved for galaxy-wide incidents or events, these meetings have so far only happened twice: once in YE 31 with the outbreak of the Second Mishhuvurthyar War, and once in YE 38 with start of the Kuvexian War.

Highs and Lows

There have been a number of historical occasions that have altered or updated the exchange's outlook for the better or worse.

In YE 33, during the Second Mishhuvurthyar War, the exchange value reached an all-time low when it closed at only 210 points. This low point was attributed to the war, but later investigations also led to suspicions of Mishhuvurthyar intermingling. In YE 38, shortly after opening the expanded Imperial Stock Exchange, the exchange reached a record value of 780 points. This influx came after an extensive period of growth, first reaching 600, and then 700 points - however, this all-time high has yet to be broken again. The share values of Origin Motor Corporation reached the highest value of all time in the exchange, valuing at 3,830 KS/per share in early YE 40.

Also during the Second Mishhuvurthyar War, the price on precious metals skyrocketed, as bankers, stockbrokers, and investors paid heavy money for gold, silver, and - especially - diamonds. The market for building materials plummeted however, as the Star Army of Yamatai purchased and produced metals like titanium, aluminium, and steel in bulk loads. Both the building and precious metals markets renormalized after the war.
