Jerome Powell
Jerome Powell is an American lawyer, former investment banker, and member of the Federal Reserve’s Board of Governors. He served as Chair of the Federal Reserve from February 2018 until May 2026. During his chairmanship, traders closely followed his speeches and press conferences for information about interest rates, inflation, employment, and monetary policy. Powell first joined the Board of Governors in 2012 and continues to serve as a governor after leaving the chairmanship, with his Board term scheduled to end in January 2028. Unlike many previous Fed chairs, he trained as a lawyer rather than completing advanced academic study in economics.
Job Openings and Labor Turnover Survey (JOLTS)
The Job Openings and Labor Turnover Survey, usually shortened to JOLTS, shows movement within the US labour market. It reports job openings, hires, voluntary resignations, layoffs, dismissals, and other separations. The number of openings indicates how many positions employers are trying to fill. The quits figure receives particular attention because workers are usually more willing to leave voluntarily when they believe other jobs are available. Job openings are counted on the last business day of the month, while hires and separations cover activity throughout the month. JOLTS therefore adds detail that cannot be seen from the headline monthly payroll figure alone.
Jobber
A jobber was a market maker on the London Stock Exchange before the 1986 reforms known as the Big Bang. Jobbers held shares in their own trading books and quoted one price for buying and another for selling. Their income mainly came from the difference between those prices. Investors did not normally place orders with jobbers directly. Instead, a stockbroker received the client’s instructions and dealt with a jobber on the client’s behalf. The distinction between brokers and jobbers disappeared as London’s market became more competitive and electronic. Today, the word appears mainly in historical accounts of British share trading.
Joint venture
A business arrangement where two or more parties agree to pool their resources to achieve a specific goal.
Jordanian Dinar (JOD)
The Jordanian Dinar, carrying the code JOD, is Jordan’s official currency. One dinar can be divided into 100 qirsh or 1,000 fils, so amounts may be written using three decimal places. JOD 2.500, for example, means two dinars and 500 fils. The Central Bank of Jordan maintains a fixed exchange-rate arrangement linking the dinar closely to the US dollar. As a result, JOD does not move freely against USD in the same way as many floating currencies. The dinar entered circulation in 1950, replacing the Palestinian pound that had previously been used in Jordan.
