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 five segments, the money, bond, equity and currency markets and financial intermediaries, from 0 (none) to 1 (stress everywhere at once).
financial stress index
An index that combines market prices into one number for how strained financial conditions are; zero is average, positive is above-average stress.
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.
GDPNow The Atlanta Fed's running estimate of current-quarter GDP growth
A model estimate of the current quarter's US GDP growth, updated after every data release, months before the official number.
Decision Maker Panel The Bank of England's monthly survey of chief financial officers
A monthly Bank of England survey of about 2,500 firms' finance chiefs on their sales, prices, employment, wages and uncertainty.
Economy Watchers Survey Japan's monthly survey of people who observe the economy at street level
A Cabinet Office survey of taxi drivers, shop staff, restaurant managers and recruiters on whether conditions are improving; 50 is neutral.
M4 The United Kingdom's broad money supply
The UK's measure of broad money: sterling deposits and short-term instruments held by households and firms.
TSF Total social financing
China's broadest measure of credit to the real economy, including bank loans, bonds and shadow finance, published monthly by the central bank.
house prices Nominal residential property prices, year on year
Nominal house prices against a year earlier; two quarters of falls mark the point at which a slowdown reaches household balance sheets and bank collateral.
government debt Credit to the general government as a share of GDP
What the state owes as a share of a year's output; shown for context because no published line separates safe from unsafe, and the level explains how much room a government has to respond.
real policy rate The policy rate minus core inflation
The policy rate less core inflation over the past year: how hard monetary policy is braking. It triggers when it is a point above its ten-year mean and the central bank is still raising.
labour trigger The Sahm-rule construction applied to each region's unemployment rate
When the unemployment rate rises half a point above its low of the past year, the economy is in recession; a rule that has not missed a US recession since 1970.
activity survey A monthly survey of firms or consumers that turns before the hard data
Surveys of businesses and households published within days of the month's end; below their neutral line, more respondents see contraction than growth.
credit impulse The change in the flow of new credit, and lending growth more generally
Whether banks are lending more or less than a year ago; the change in new lending leads demand, and the zero line is a worldstat.us construction.
trade bellwether Goods exports as an early read on global demand
A region's goods exports, year on year in dollars; two months of falling exports is the sign used here that external demand has turned.
broad dollar index The Federal Reserve's trade-weighted index of the dollar against a broad group of currencies
The dollar against 26 trading partners' currencies, weighted by trade; a dollar rising more than 5 % in a year tightens conditions for everyone who borrows in dollars.

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 phrase for how broadly the indicators are clear of their thresholds: Broad growth (65 and above), Uneven growth (50 to 64), Broad slowing (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.
policy rate The short-term interest rate a central bank sets
The overnight rate a central bank targets to steer inflation and demand; shown for context because it explains the yield curve and the credit cycle rather than predicting them.

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.
pp Percentage points
The difference between two percentages. A rate rising from 4 % to 4.5 % has risen 0.5 pp, not 12.5 %.
y/y Year on year
The change against the same period a year earlier, which removes seasonal effects without statistical adjustment.
3m on 3m Latest three months against the previous three
