Credit Conditions Turn Tighter Than Average for First Time Since the Tariff Crisis
The Chicago Fed's credit sub-index has crossed above zero -- meaning conditions are now tighter than the historical average -- for the first time since the spring 2025 tariff shock, as the broader NFCI tightens for a twelfth straight week.
Federal Reserve Bank of Chicago / FRED
The Federal Reserve Bank of Chicago's weekly financial conditions report, released April 8, shows credit conditions in the United States are now tighter than the historical average for the first time in nearly a year. The NFCI credit sub-index reached +0.015 for the week ending April 3 -- its highest reading since the tariff-driven stress of spring 2025.
The crossing matters because it marks a qualitative shift. For the past 11 months, credit markets had been operating in looser-than-average territory, cushioning borrowers and markets from the Fed's elevated policy rate. That cushion is gone.
The NFCI credit sub-index measures conditions across corporate bond markets, commercial paper, asset-backed securities, and bank lending standards. It crossed zero in the week of March 13 and has climbed steadily since, reaching +0.015 by April 3.
The last time this index was positive was during the tariff crisis of March-May 2025, when it peaked at +0.022. Before that, the prior episode was July-August 2024. Each zero-crossing has coincided with a period of meaningful market stress.
Corporate bond spreads confirm the shift. The gap between BAA-rated corporate bonds and the federal funds rate widened to 2.40% in March, up from 1.60% in September 2025 -- an 80-basis-point increase in six months, reflecting a sustained repricing of credit risk.
Risk: The Fastest-Moving Component
The NFCI risk sub-index, which captures volatility and risk appetite across equity, bond, and money markets, has moved from -0.652 in late January to -0.481 -- a 0.171-point deterioration in ten weeks. While still below zero (indicating risk conditions remain looser than the historical average), the pace of change is notable. The sub-index moved this fast in only two prior episodes in the past two years: the tariff shock of spring 2025 and the regional bank stress of mid-2024.
The VIX, one component of the risk calculation, has been trading above 24 for most of the past three weeks, with a spike above 31 during the late-March Iran escalation.
Leverage: Approaching the Line
The leverage sub-index -- measuring conditions in bank lending, repo markets, and dealer balance sheets -- has moved from -0.053 in January to -0.004, effectively at the historical average. This is the least dramatic shift in absolute terms but the most consistent: the sub-index has moved toward zero every single week since mid-January.
St. Louis Stress Index: A Second Confirmation
The St. Louis Fed's Financial Stress Index, which uses a different methodology and different inputs than the Chicago NFCI, tells the same story. It has risen from -0.712 in late January to -0.241 on April 3 -- nearly tripling toward its zero line. The index briefly touched -0.182 on March 27, its highest reading since late November 2025.
The Picture
Each of these indicators measures something slightly different. The NFCI tracks 105 financial variables. The STLFSI uses 18. The BAA spread is a single price signal. That they are all moving in the same direction, at the same time, for the same duration, reduces the chance this is noise.
The tightening has unfolded against a specific backdrop: oil above $110 on Iran tensions, mortgage rates at 6.46%, the DHS shutdown entering its eighth week, and a ceasefire that fractured within 24 hours of being announced. None of these factors alone explains the shift -- the NFCI had already been tightening for weeks before the Iran escalation in late March accelerated it.
The practical consequence is that credit is now more expensive, and becoming more so, than it has been at any point since the tariff shock one year ago. For businesses rolling over debt, for banks setting lending standards, and for a Fed weighing whether to cut rates, the signal is the same: the financial system is absorbing stress, and the buffer that existed in January is nearly gone.
