Indicators

CLI Composite leading indicator: The OECD's index of series that turn six to nine months before GDP; 100 is trend growth.
ESI Economic Sentiment Indicator: The European Commission's composite of business and consumer surveys; 100 is its long-run average.
CFNAI Chicago Fed National Activity Index: A weighted average of 85 monthly US series; zero is trend growth, and a three-month average below −0.70 has marked every recession since 1967.
CISS Composite Indicator of Systemic Stress: The ECB's daily measure of stress across money, bond, equity and currency markets, from 0 (none) to 1 (stress everywhere at once).

HICP Harmonised Index of Consumer Prices: The consumer price index compiled the same way in every EU country, and the measure the ECB targets at 2 %.
CPI Consumer price index: The price of a fixed basket of goods and services bought by households; its yearly change is the inflation rate.
core CPI Inflation excluding the most volatile items: Inflation with food and energy removed, so that a bad harvest or an oil shock does not hide the underlying trend.
PMI Purchasing managers' index: A monthly survey of purchasing managers; above 50 more firms report growth than contraction.
DSR Debt service ratio: Interest plus repayments of the private non-financial sector as a share of its income, published quarterly by the BIS.
credit-to-GDP gap Credit to the private sector as a share of GDP, minus its long-run trend: How far private credit has run ahead of its trend relative to the economy; the Basel early-warning gauge for banking crises.
Sahm rule A real-time recession indicator built from the unemployment rate: When the three-month average unemployment rate rises 0.50 points above its low of the past year, a US recession has begun.
initial claims New claims for unemployment insurance: The number of people filing for unemployment benefit for the first time each week; the earliest published labour-market signal.

Concepts

yield curve The spread between long and short government bond yields: Long yields minus short yields. When short rates exceed long ones the curve is inverted, which has preceded most recessions.
coincident Leading, coincident and lagging indicators: A leading indicator turns before the economy does, a coincident one at the same time, a lagging one afterwards.
regime The four bands on the world score: One word for where the world economy sits: Expansion (65 and above), Late cycle (50 to 64), Slowdown (35 to 49) or Contraction (below 35).
threshold The published line each indicator is measured against: The level at which an indicator counts as having signalled, taken from the literature or the publisher and printed on every indicator page.
false positive A signal that fired without the event following: A crossing that was not followed by a recession, shown in the track record rather than hidden.
tolerance band The range around an inflation target within which the central bank need not act: The margin either side of an inflation target, such as India's 2 to 6 % around a 4 % target.
seasonally adjusted Data with the regular yearly pattern removed: The series with predictable seasonal swings, such as Christmas hiring or summer holidays, statistically removed so months can be compared.
diffusion index The share of respondents reporting an increase minus the share reporting a decrease: A survey score where zero (or 50, depending on the convention) means as many respondents see things improving as worsening.
countercyclical capital buffer Extra bank capital required when credit is growing too fast: The Basel III rule that tells regulators to demand more bank capital as the credit-to-GDP gap rises, reaching the maximum at a gap of 10 points.
recession A broad, sustained decline in economic activity: A significant decline in activity spread across the economy, lasting more than a few months; dated after the fact by committees such as the NBER.
revision A change to a number after it was first published: Publishers update past figures as more complete data arrive; the first published number is a vintage.

Units and abbreviations

GDP Gross domestic product: The total value of everything an economy produces in a period; the measure the indicators here are trying to anticipate.
