Why is inflation important to economists




















Most of the data they have to work with is old data, so an understanding of trends is very important. At its best, the Fed is hoping to always be ahead of the curve, anticipating what is around the corner tomorrow so it can be maneuvered around today.

There is as much debate over how to calculate GDP and inflation as there is about what to do with them when they're published. Analysts and economists alike will often start picking apart the GDP figure or discounting the inflation figure by some amount, especially when it suits their position in the markets at that time.

Once we take into account hedonic adjustments for "quality improvements," re-weighting, and seasonality adjustments, there isn't much left that hasn't been factored, smoothed, or weighted in one way or another. Still, there is a methodology being used, and as long as no fundamental changes to it are made, we can look at rates of change in the CPI as measured by inflation and know that we are comparing from a consistent base.

Keeping a close eye on inflation is most important for fixed-income investors because future income streams must be discounted by inflation to determine how much value today's money will have in the future.

Real returns all of our stock market discussions should be pared down to this ultimate metric are the returns on investment that are left after commissions, taxes, inflation, and all other frictional costs are taken into account. As long as inflation is moderate, the stock market provides the best chances for this compared to fixed income and cash.

There are times when it is most helpful to simply take the inflation and GDP numbers at face value and move on, especially since there are many other things that demand our attention as investors. However, it is valuable to re-expose ourselves to the underlying theories behind the numbers from time to time so that we can put our potential for investment returns into the proper perspective.

Key Takeaways Individual investors need to find a level of understanding of gross domestic product GDP and inflation that assists their decision-making without inundating them with too much unnecessary data.

Unlike bonds, some assets rise in price as inflation rises. Price rises can sometimes offset the negative impact of inflation:.

To combat the negative impact of inflation, returns on some types of fixed income securities are linked to changes in inflation:. Through its monetary policy tools, the Fed works to encourage full employment and stabilize prices.

All opinions are subject to change without notice. All investments contain risk and may lose value. Investing in the bond market is subject to risks, including market, interest rate, issuer, credit, inflation risk, and liquidity risk.

The value of most bonds and bond strategies are impacted by changes in interest rates. Bonds and bond strategies with longer durations tend to be more sensitive and volatile than those with shorter durations; bond prices generally fall as interest rates rise, and low interest rate environments increase this risk. Reductions in bond counterparty capacity may contribute to decreased market liquidity and increased price volatility. Bond investments may be worth more or less than the original cost when redeemed.

Currency rates may fluctuate significantly over short periods of time and may reduce the returns of a portfolio. Commodities contain heightened risk, including market, political, regulatory and natural conditions, and may not be appropriate for all investors. Department of Labor Statistics. There can be no guarantee that the CPI or other indexes will reflect the exact level of inflation at any given time.

It measures inflation across the basket of goods purchased by households, and is computed by taking the difference between current dollar PCE and chained dollar PCE.

The Harmonised Indices of Consumer Prices HICP is an economic indicator that measures the changes over time in the prices of consumer goods and services acquired by households. The HICP gives a comparable measure of inflation in the euro-zone, the EU, the European Economic Area and for other countries including accession and candidate countries.

It is calculated according to a harmonised approach and a single set of definitions. It also provides the official measure of consumer price inflation in the euro-zone for the purposes of monetary policy in the euro area and assessing inflation convergence as required under the Maastricht criteria. It is not possible to invest directly in an unmanaged index.

Statements concerning financial market trends or portfolio strategies are based on current market conditions, which will fluctuate. There is no guarantee that these investment strategies will work under all market conditions or are appropriate for all investors and each investor should evaluate their ability to invest for the long term, especially during periods of downturn in the market.

Wars and natural disasters are two examples that can also cause inflation to rise. One of their prime tasks is ensuring a healthy rate of inflation. Central banks do this by adjusting the money supply. The more money is available, the less each dollar or other unit of currency is worth.

The more they reduce the supply, the more each unit is worth. If the rate of inflation gets too high, a currency can become virtually worthless. Countries with high inflation rates are generally impoverished. One of the best examples of this was the German hyperinflation of , where things became so bad that people used wheelbarrows for wallets. At the same time, too much deflation—the opposite of inflation, when prices drop for an extended period of time— is bad, too.

During the Great Depression, deflation played a central role in preventing the economy from recovering. As prices continued to fall, companies struggled to turn profits, which they needed to employ people. Falling levels of employment made it impossible for the economy to stabilize. A more recent example of a central bank stepping in to introduce stability to an economy was the Federal Reserve using quantitative easing, following the financial crisis that began in In the years immediately following the recession, consumer confidence was low, but inflation remained at moderate levels.

A company that relies mostly on large deals with multi-year revenue streams may have reduced opportunity to compensate for losses in its revenue purchasing power during the period of a contract. Conversely, it can reap unanticipated gains if the purchasing power of its future revenue were to increase. A company that continually brings in new sales may be able to adjust its pricing more readily to respond to its customers' purchasing power changes.

Of course, while raising prices can promise increased revenue, any such discussion assumes that the company has the market power to increase its prices even if one or more of its competitors do not adjust their prices. On the expense side of the ledger, the impact of changes in price level depends on factors such as the proportions of cash and accrual expenses and the amounts of inventory and work-in-process that may be carried from year to year. A business that constantly buys raw materials at current prices could see its costs of goods sold respond relatively quickly to changes in the economy's price level.

A business that accrues large fractions of its costs by depreciating prior investments could see less immediate cost effects as older investments are consumed. Products with short production cycles may see relatively little impact on the cost of any given unit. However, those with a multi-year production cycle may carry accrued costs that lag behind current price levels.

Interest costs could be a special case. A company with a large proportion of fixed-rate interest costs could see the impact of those costs diminish as price levels rise but increase if price levels fall.

Conversely, companies with significant variable-rate costs could see their interest costs rise due to inflation and fall due to deflation. At the broadest level, inflation may tend to increase focus on immediate consumption rather than deferred rewards. This is particularly evident in the consumer sectors of the economy, where the value of buying something before prices rise could outweigh any impulse to save for the future.

On the opposite side, the impulse to spend quickly can be diminished when consumers believe that the same item will be materially cheaper in the near future.

Stock markets are volatile and can fluctuate significantly in response to company, industry, political, regulatory, market, or economic developments. Investing in stock involves risks, including the loss of principal.
