The Fisher effect is a theory of how nominal interest rates are determined. The original theory, which was developed by Irving Fisher in the 1920s, says that the nominal interest rate (r) is equal to the real interest rate (r*) plus expected inflation (π).

What is the Fisher effect? – Definition

The Fisher effect refers to a relationship between inflation and nominal interest rates. In other words, it is the idea that each increase in inflation leads to an equal rise in nominal interest rates (or vice versa).

It is used as an indicator of whether people are holding cash balances or investing them. If there is no Fisher effect, then people will invest their money until they find the highest return possible before they start buying goods and services. However, if there is a positive Fisher effect then people will likely hold onto their money instead of investing it for better returns.

This means that investors see less risk associated with holding onto cash than making investments because inflation has already pushed up the price of goods so much that any gains from investments aren’t worth risking losing some money from price increases on products or services purchased with dollars held in currency form over time periods long enough for them not only earn interest but also see prices go up due to inflationary pressures which could lower purchasing power if savings were invested rather than spent today (like when someone buys bonds instead of stocks).

Factors that influence the Fisher effect

Inflation, deflation, uncertainty, and risk are the enemies of your portfolio. Fortunately, stocks are a great hedge against all of them.

Stocks go up when inflation is high because they’re priced in dollars and you get more back for every dollar you invest. When inflation is subdued, stocks go down because their profits get diluted by lower prices for goods and services.

Inflation also makes it harder to predict future earnings so investors often buy more shares when it appears that inflation will rise (because they’ll get more money out of those shares). This causes stock prices to increase even more than expected by analysts who don’t fully account for potential volatility caused by changing conditions in the economy or geopolitical climate (like trade wars). In other words: uncertainty leads to higher stock values!

Deflation is bad news because people tend not to spend if prices are falling—which means demand for goods goes down as supply increases relative to demand; this lowers production costs but also reduces profits from sales throughout an entire industry sector until no one wants anything anymore except maybe bread from mom’s store down the main street… She’s already sold out because everyone else has been hoarding stuff like crazy too!

How to calculate the Fisher effect?

The Fisher effect formula is as follows:

\text {Nominal Interest Rate} = \text {Real Interest Rate} + \text {Expected Inflation Rate}

The real interest rate is the interest rate after inflation. That is, it’s how much you’re earning (or losing) in terms of purchasing power. If you invest $1000 and earn 3% over two years, that means your purchasing power will increase by 3% during that time period; if inflation were at 5%, your dollar would actually be worth less than when you invested it—you’d see a loss even though you earned something in nominal terms.

The nominal interest rate is the interest rate before inflation. That’s what lenders charge borrowers on loans based on their expectation of future inflation; if they expect prices to go up 10% over the next year and charge 4% on loans, then buying a house with them will cost about 4% more than buying one without any such loan—that’s why economists say “the borrower pays” when discussing this relationship between borrowers/lenders and expected inflationary effects on home prices/interest rates: because lenders can only raise their rates so much before they lose customers who don’t want to pay higher fees just because they’re worried about losing value!
