Question

In the financial market, what causes a movement along the demand curve? What causes a shift in the demand curve?

Short answer

A movement along the demand curve in the financial market occurs due to a change in the price of the financial asset, resulting in a change in the quantity demanded while keeping other factors constant. On the other hand, a shift in the demand curve is caused by factors other than price, such as income, interest rates, and market expectations, affecting the overall level of demand for financial assets. For example, a decrease in the price of bonds causes a movement along the curve, while a central bank lowering interest rates causes a shift in the demand curve.

Step-by-step solution

Understand the demand curve

The demand curve is a graphical representation of the relationship between the prices of financial assets (e.g., stocks, bonds, or currencies) and the quantity demanded by the market participants (investors and traders). It slopes downward, which means that as prices go down, demand increases, and as prices go up, demand decreases.

Explain a movement along the demand curve

A movement along the demand curve occurs when the quantity demanded changes because of a change in the price of the financial asset, while all other factors that affect demand remain constant. In other words, a movement along the curve is a direct result of a change in price. For example, let's say the bond market experiences a decrease in the price of bonds. This makes bonds more attractive to investors, thus increasing the quantity demanded. As a result, we observe a movement along the demand curve from a higher price and lower quantity demanded to a lower price and higher quantity demanded.

Explain a shift in the demand curve

A shift in the demand curve occurs when the entire curve moves either to the right (an increase in demand) or to the left (a decrease in demand) due to factors other than the price of the financial asset. These factors can include changes in income, interest rates, preferences of market participants, market expectations, and other macro-economic variables. For example, consider a scenario where the central bank lowers interest rates. Lower interest rates make borrowing cheaper and may encourage more investments in the financial market, thus increasing the demand for financial assets. Consequently, we observe a rightward shift in the demand curve, as market participants demand more financial assets at any given price level than before the interest rate change.

Differentiate between the two concepts

To summarize, a movement along the demand curve is caused by a change in the price of the financial asset, while a shift in the demand curve is caused by factors other than price, such as income, interest rates, and market expectations. A movement along the curve represents a change in the quantity demanded due to a change in price, while a shift in the curve represents a change in the overall level of demand for financial assets.
