Economy what is inflation

Because households spend more on childcare than books, childcare has a greater weight in the basket. In this example, childcare accounts for 73 per cent of the basket and books account for the remaining 27 per cent.

Using these weights, and the change in prices of the items, annual inflation for this basket was 4. The ABS collects prices from a wide range of sources, such as retailers, supermarkets, department stores and websites where households shop.

It also collects prices from government authorities, energy providers and real estate agents. For some items, the ABS has access to data that allows it to record prices frequently. For example, scanner data from supermarkets give information about the price and number of items a consumer buys in one transaction. For other items, the ABS records prices either monthly, quarterly or annually. In total, the ABS collects around , prices each quarter.

In deciding which goods and services to include in the CPI basket and what their weights should be, the ABS uses information about how much — and on what — households in Australia spend their income.

If households spend more of their income on one item, that item will have a larger weight in the CPI. For example, the ABS included smart phones in the CPI to reflect consumers taking advantage of advances in technology. Data on household spending across all items is only available approximately every five years or so. These indicators exclude items that have particularly large price changes either frequently or in a given quarter. Large price changes can often be due to temporary factors, which are sometimes unrelated to broad conditions in the economy.

For example:. In contrast, price changes for a broad range of items may indicate a shift in economic conditions. The Reserve Bank may decide to respond to this by changing interest rates see Explainer: Australia's Inflation Target.

In Australia, the most important indicators of underlying inflation are the trimmed mean and the weighted median see Box: Calculating the Trimmed Mean and the Weighted Median.

Prices of fruit, vegetables and fuel are usually very volatile because they are often affected by supply disruptions, such as unusual weather, or changes in how much oil is supplied to the world market. The CPI excluding volatile items always removes the same items, while the items that are removed from the trimmed mean and weighted median can change each quarter, depending on which items had particularly large price changes.

Businesses that enter into long-term contracts with suppliers frequently use the PPI to automatically adjust the rate they pay for raw goods and services over time. Otherwise, suppliers would lock themselves into years-long contracts at rates that might lose them purchasing power over the long term. PCE is published by the Bureau of Economic Analysis, which considers a broader range of consumer expenditures, like healthcare spending.

It also updates the basket of goods it uses for calculations based on what consumers are actually spending money on each month, rather than limiting data to a fixed set of goods. The Federal Reserve is the central bank of the U. This level of inflation gives the FOMC scope to jump-start the economy during downturns by decreasing interest rates, which makes borrowing cheaper and helps boost consumption. Lower interest rates reduce costs for businesses and consumers to borrow money, stimulating the economy.

Lower interest rates also mean individuals earn less on their savings, encouraging them to spend. But all this extra demand can push up inflation. Even a moderate rate of inflation means that money held as cash or in low-APY bank accounts will lose purchasing power over time. You can beat inflation and boost your purchasing power by investing your money in certain assets.

Investing in the stock market is one way to potentially beat inflation. While individual stock prices may fall or single companies may go out of business, and bear markets may even depress indices for certain periods, broader stock market indexes rise over the long run, beating inflation.

Investing in individual stocks offers no guarantees, but a well-diversified investment in a broad market index fund can grow wealth over decades and beat inflation. Beat Inflation with Bonds Bonds on average offer lower returns than stocks, but they can also regularly beat inflation.

Risk averse investors or those approaching or in retirement may seek out the more consistent returns of investments in bonds and bond funds to beat inflation. Aggregate Bond Index, a benchmark index tracking thousands of U.

Even accounting for inflation, those with money in bonds would have seen modest increases in the purchasing power of their money. Keep in mind, though, that bond yields are tied to the overall economy and current bond yields may be drastically less than historical bond yields. TIPS automatically adjust the value of your investment based on changes to CPI, meaning the value of your bond rises with inflation. TIPS pay interest over the five-, , or year life of the bond. Many investors consider gold as the ultimate inflation hedge , although the debate over this proposition is far from settled.

From April to June , for instance, gold increased in value on average 7. When adjusted for inflation, returns average 3. Investing in gold also comes with its own unique set of challenges. If you buy gold, you have to find a secure location to store it, which comes with costs of its own. John Schmidt is the Assistant Assigning Editor for investing and retirement.

For example, if a hurricane destroys a crop such as corn, prices can rise across the economy since corn is used in many products. Demand-pull inflation can be caused by strong consumer demand for a product or service. When there's a surge in demand for a wide breadth of goods across an economy, their prices tend to increase. While this is not often a concern for short-term imbalances of supply and demand, sustained demand can reverberate in the economy and raise costs for other goods; the result is demand-pull inflation.

Consumer confidence tends to be high when unemployment is low, and wages are rising—leading to more spending. Economic expansion has a direct impact on the level of consumer spending in an economy, which can lead to a high demand for products and services.

As the demand for a particular good or service increases, the available supply decreases. When fewer items are available, consumers are willing to pay more to obtain the item—as outlined in the economic principle of supply and demand. The result is higher prices due to demand-pull inflation. Companies also play a role in inflation, especially if they manufacture popular products.

A company can raise prices simply because consumers are willing to pay the increased amount. Corporations also raise prices freely when the item for sale is something consumers need for everyday existence, such as oil and gas. However, it's the demand from consumers that provides the corporations with the leverage to raise prices.

The housing market, for example, has seen its ups and downs over the years. If homes are in demand because the economy is experiencing an expansion, home prices will rise. The demand also impacts ancillary products and services that support the housing industry. Construction products such as lumber and steel, as well as the nails and rivets used in homes, might all see increases in demand resulting from higher demand for homes. Expansionary fiscal policy by governments can increase the amount of discretionary income for both businesses and consumers.

If a government cuts taxes, businesses may spend it on capital improvements, employee compensation, or new hiring. Consumers may purchase more goods as well. The government could also stimulate the economy by increasing spending on infrastructure projects. The result could be an increase in demand for goods and services, leading to price increases. Expansionary monetary policy by central banks can lower interest rates.

Central banks like the Federal Reserve can lower the cost for banks to lend, which allows banks to lend more money to businesses and consumers.

The increase in money available throughout the economy leads to more spending and demand for goods and services. There are a few metrics that are used to measure the inflation rate. One of the most popular is the Consumer Price Index CPI , which measures prices for a basket of goods and services in the economy, including food, cars, education, and recreation.

In April , the Consumer Price Index increased 0. When compared to the year prior, the full index increased 4. Another measure of inflation is the Producer Price Index PPI , which reports the price changes that affect domestic producers. The PPI measures prices for fuel, farm products meats and grains , chemical products, and metals.

If the price increases that cause the PPI to spike get passed onto consumers, it will be reflected in the Consumer Price Index. While consumers experience little benefit from inflation, investors can enjoy a boost if they hold assets in markets affected by inflation. For example, those who are invested in energy companies might see a rise in their stock prices if energy prices are rising.

Some companies reap the rewards of inflation if they can charge more for their products as a result of a surge in demand for their goods. If the economy is performing well and housing demand is high, home-building companies can charge higher prices for selling homes.

In other words, inflation can provide businesses with pricing power and increase their profit margins. If profit margins are rising, it means the prices that companies charge for their products are increasing at a faster rate than increases in production costs.

Also, business owners can deliberately withhold supplies from the market, allowing prices to rise to a favorable level. However, companies can also be hurt by inflation if it's the result of a surge in production costs.

Companies are at risk if they're unable to pass on the higher costs to consumers through higher prices.
