Y-axis:

The Y-axis is the vertical line along which one variable is measured in a 2-dimensional system of Cartesian coordinates. See the Cartesian coordinate system figure for more discussion.

Yankee Bond:

A Yankee bond is a bond issued by a foreign corporation but for which payment in U.S. dollars is specified. This allows U.S. investors to avoid exchange rate risk while investing in foreign institutions.

yap money:

yield curve:

yen:

The yen (¥) is the official currency of Japan.

Y-intercept:

The Y-intercept is the value of b in the formula of linear equation Y = mX + b. In a 2-dimension Cartesian space, the slope of the straight line is m, and b is the value of the variable on the Y-axis when the variable on the X-axis is zero. See the Cartesian coordinate system figure for more discussion.

yuan:

The yuan is the official currency of China.
