AI summary
The IMF's Back to Basics material defines inflation exactly this way — "the rate of increase in prices over a given period of time" — and independent central-bank sources (ECB, Bundesbank, Federal Reserve, St. Louis Fed) similarly describe inflation as a broad, sustained rise in the general price level measured over a period such as a year. The definition is uncontested across these authoritative sources.

Statement 3 of 33
Inflation is the rate of increase in prices over a given period of time.
AI summary
The IMF's own 'Inflation: Prices on the Rise' article and its accompanying PDF state that inflation is 'most commonly measured over a year.' The St. Louis Fed similarly describes inflation as the percentage change in overall prices 'over a specified period, typically a year,' and the Congressional Research Service notes inflation is generally measured across 12-month periods.
Factual claim · Statement 4 of 33 · 96% confidence
AI summary
The IMF's own Back to Basics material states that 'the percentage change in the CPI over a certain period is consumer price inflation,' matching the claim exactly. Eurostat and the OECD independently describe the CPI-based inflation rate as the percentage change in the consumer price index between periods.
Factual claim · Statement 5 of 33
AI summary
The IMF's own Back to Basics article gives this exact example, defining inflation as the percentage change in the CPI (110 vs. A base of 100 equals 10 percent). Independent sources agree: the BLS CPI FAQ says an index of 110 means a 10-percent increase in price since the reference period, and the St. Louis Fed lesson states a CPI value of 110 means a 10 percent increase in the price level since the base year.

Factual claim · Statement 6 of 33
AI summary
Independent sources such as the Congressional Research Service and the St. Louis Fed confirm that core inflation is commonly defined by removing volatile food and energy prices. However, those standard definitions make no mention of excluding government-set prices, an element that appears only in this IMF publication, so the claim is only partly supported by outside evidence and its full scope is narrower than the common definition.

AI summary
The IMF's Back to Basics material states that an overall inflation index with broader coverage such as the GDP deflator shows how, on average, prices change over time for everything produced in an economy, and NHS England Digital likewise calls the GDP deflator a much broader price index than the CPI because it reflects the prices of all domestically produced goods and services.

Statement 7 of 33
The GDP deflator is an index with broader coverage than the CPI that shows how prices change over time for everything produced in an economy.
AI summary
Multiple authoritative sources describe the GDP deflator as a broader index than the CPI that reflects the prices of all domestically produced goods and services, including government spending on items like military equipment, not just consumer purchases. The IMF's own explainer stating the deflator 'includes nonconsumer items (such as military spending)' is corroborated by independent references such as the GOV.UK GDP deflators user guide and OpenStax, which note the deflator covers government and investment spending components.

AI summary
The IMF's own Back to Basics publications state the consumer price index basket is 'mostly kept constant over time for consistency, but is tweaked occasionally to reflect changing consumption patterns.' Independent national statistical agencies corroborate the practice, with the U.S. BLS noting that major changes to the CPI item structure are intentionally infrequent and only made to reflect shifts in the consumer marketplace.

AI summary
The IMF's "Inflation: Prices on the Rise" and its companion Back to Basics pages state that when households' nominal income does not increase as much as prices, their purchasing power or real (inflation-adjusted) income falls. Independent economics sources (Investopedia, Pearson, learn-economics) describe the same relationship between nominal income, prices, and real income.

Factual claim · Statement 11 of 33
AI summary
The IMF sentence being checked actually reads "Some prices (traded commodities) change every day," so it only claims that many commodity prices move daily, not all. Live quotes (Bloomberg, TradingKey, Investing.com) confirm daily price moves for major commodities like gold, crude oil and copper, but Saxo Bank notes that while some commodities trade in large volumes every day, others such as certain agricultural goods and niche metals have limited trading activity — so the unqualified universal version overstates the original claim.

Economics sources consistently describe contract-set wages as sticky: the Reed coursebook notes most wages are set for a year or more in explicit or implicit contracts, Economics Help lists employment and annual contracts among the reasons wages are sticky, and the Boston Fed finds wages appear very sticky at the micro level. These independent sources support the claim that contract-established wages are sticky.

Factual claim · Statement 12 of 33
AI summary
The IMF's own Back to Basics inflation material states that "unevenly rising prices inevitably reduce the purchasing power of some consumers," and this is corroborated independently by Italian central bank research finding that heterogeneous price increases lead to "very differentiated purchasing power losses across households" and by Banque de France analysis of uneven exposure to inflation. The proposition is a standard, well-supported distributional point about inflation.

The IMF article "Inflation: Prices on the Rise" states directly that "this erosion of real income is described as the single biggest cost of inflation," and the companion IMF PDF says "this erosion of real income is the single biggest cost of inflation."

Factual claim · Statement 13 of 33
AI summary
The IMF's Back to Basics article on inflation states the point directly: pensioners who receive a fixed 5 percent yearly increase see their purchasing power fall whenever inflation exceeds 5 percent, since the nominal increase no longer keeps pace with prices. The same example appears verbatim in the IMF article text, and it follows arithmetically from real income being nominal income adjusted for inflation.

Factual claim · Statement 14 of 33 · 95% confidence
AI summary
The IMF Back to Basics article states that a borrower paying a fixed-rate mortgage of 5 percent would benefit from 5 percent inflation because the real interest rate (nominal minus inflation) would be zero. Federal Reserve Education materials independently confirm the same arithmetic and that borrowers benefit from lower real interest rates when inflation is unexpected, while lenders lose.

AI summary
The claim restates a standard result stated verbatim in the IMF's 'Inflation: Prices on the Rise' and echoed in its 2010 Back to Basics piece: if nominal rates don't incorporate inflation, the lender's real return falls. Independent sources agree — Federal Reserve Education notes that 'Lenders, on the other hand, are the losers in this case,' and the OpenStax-based economics text explains that when rates are fixed, inflation penalizes suppliers of financial capital.

The IMF's own Back to Basics article and its 2009 Zimbabwe staff report both state that estimated annual inflation hit about 500 billion percent in 2008, and a peer-reviewed article cites the same IMF (2009) estimate. The figure is explicitly framed as an estimate, and other analysts dispute the exact peak, but the claim as an IMF estimate is supported.

Historical examples confirm the claim: Zimbabwe abandoned its currency in 2009, and the Federal Reserve notes that some countries give up their domestic currency altogether (e.g., Ecuador and El Salvador). The IMF's 2010 article also states countries have had to take painful measures, sometimes by giving up their national currency.
Factual claim · Statement 19 of 33 · 90% confidence
AI summary
The IMF's Back to Basics article states that when prices are falling, consumers delay purchases, leading to less economic activity and lower economic growth. Independent sources including Charles Schwab and the World Economic Forum similarly describe delayed consumer spending as a deflationary mechanism that can slow growth, though some economists debate how strong the effect is.

AI summary
The IMF's own Back to Basics article states that Japan had a long period of nearly no economic growth largely because of deflation, and sources such as the BIS confirm Japan endured long-lasting deflation from the mid-1990s. But the causal framing is contested: Bank of Japan and IMF analyses describe chronic deflation as coinciding with and partly reflecting a structural decline in Japan's growth potential (aging population, falling productivity), with growth averaging a low but non-zero rate (about 1.1 percent in 1991-2001), so deflation is better described as one mutually reinforcing factor than as the single dominant cause.

Federal Reserve Governor Donald Kohn's 2010 speech states the Fed took steps to reinforce understanding of its inflation objective 'to prevent the development of deflationary expectations,' alongside rate guidance and large-scale securities purchases, while the Philadelphia Fed notes policymakers feared a U.S. Deflation spiral after 2007. The San Francisco Fed adds that the Fed's vigorous actions with other central banks 'sent a clear message that deflation won't be tolerated,' matching the IMF article's description.

AI summary
The IMF's own Back to Basics explainer states that long-lasting episodes of high inflation are often the result of lax monetary policy, and independent sources agree: a BIS review states that 'persistent inflation is the consequence of a lax monetary stance,' and a Congressional Research Service report describes inflation as ultimately driven by monetary policy that is persistently too 'easy.' This reflects a mainstream economics consensus rather than a contested factual point.

The IMF's Back to Basics article states exactly that if the money supply grows too big relative to the size of an economy, the currency's purchasing power falls (the quantity theory of money). Independent sources, Investopedia's entry on the quantity theory of money and the St. Louis Fed's explanation of money and prices, corroborate that an excessive growth of the money supply lowers money's value and purchasing power.

The Cleveland Fed explains that 'cost-push inflation' occurs when the cost of producing goods and services rises notably or when they can't be produced in sufficient quantities, listing natural disasters, pandemics, and supply chain disruptions as causes. The Reserve Bank of Australia and the Congressional Research Service likewise state that cost-push inflation arises from supply disruptions and increases in production costs that reduce aggregate supply.

The IMF's "Back to Basics" article states that the food and fuel inflation of 2008 was a cost-push case in which sharply rising food and fuel prices "were transmitted from country to country by trade." Independent FAO and OECD analyses of the 2006-08 food crisis corroborate that international food and fuel price shocks passed through to domestic markets via trade, while noting the transmission was often only partial where countries intervened.

The Congressional Research Service explains that fiscal policy can directly increase aggregate demand via government spending, tax cuts, or transfers, and that lowering interest rates encourages borrowing and spending, while the AS-AD chapter notes a positive demand shock and expansive monetary policy both shift the aggregate demand curve to the right.

The IMF's own "Back to Basics" material states that if an increase in demand exceeds an economy's production capacity, the resulting strain on resources is reflected in "demand-pull" inflation, and the Reserve Bank of Australia and Colombia's Banco de la República give the same definition. Independent reference sources such as Investopedia and the Congressional Research Service also describe demand-pull inflation as arising when demand outpaces the economy's capacity to produce.

The Congressional Research Service notes that the Fed typically uses contractionary monetary policy—raising the federal funds rate—during periods of high inflation, and that rising interest rates lower prices by decreasing demand.

Administrative price-setting was used by some governments in 2008.
AI summary
The IMF's own Back to Basics text states that governments may directly set prices to prevent high food and fuel prices from passing through and that 'such administrative price-setting measures usually result in the government's accrual of large subsidy bills to compensate producers for lost income.' Independent IMF and World Bank analyses reach the same conclusion, noting that policies limiting pass-through result in costly broad-based subsidies and that price ceilings require producer compensation, converting price control into a substantial public expenditure problem.
