What Happens When the Fed Cuts Rates to Zero?
Zero interest-rate policy (ZIRP) marks extreme monetary easing. What happens to markets, saving, and the economy when the Fed takes policy rates to zero?
Trigger: Federal Funds Rate falls to 0-0.25%
Current Status
Right now, Federal Funds Rate is at 3.64%, flat +0.0% over 30 days and +0.0% over 90 days.
Restrictive, meaningful drag on credit and growth

The Mechanics
The Federal Reserve sets the fed funds rate in a target range. A target of 0-0.25% represents the effective lower bound (ELB), the point beyond which conventional rate policy can no longer stimulate. Reaching zero signals the Fed views conventional policy as insufficient and is deploying emergency measures.
Once at the ELB, the Fed typically adds forward guidance (promising to hold rates low for extended periods) and quantitative easing (asset purchases expanding the balance sheet). These tools work through different channels: forward guidance lowers expected future short rates, while QE compresses term premia and credit spreads.
ZIRP has only been used twice in US history: 2008-2015 (following the Great Financial Crisis) and 2020-2022 (COVID). Both episodes featured massive balance-sheet expansion and explicit forward guidance. The challenge is exiting: premature tightening can trigger deflationary spirals (see Japan 1990s), while delayed tightening risks inflation (see 2022 experience).
Historical Context
The Fed took rates to 0-0.25% on December 16, 2008, and held them there until December 2015, seven years at the zero bound. The exit featured four rounds of QE (QE1, QE2, Operation Twist, QE3), forward guidance that evolved from calendar-based to state-contingent (tying rate hikes to unemployment and inflation thresholds). The 2020 ZIRP began March 15, 2020, with emergency 100 bp cut to zero, massive QE ($120B/month in Treasuries and MBS), and dovish forward guidance. Exit began March 2022 but proved far more rapid than 2015-2019: 525 bps of tightening in 16 months vs the 300 bps spread over 3 years (2015-2018). Inflation outcomes differed dramatically: 2008-era ZIRP never produced sustained inflation; 2020-era produced the worst inflation since 1982.
Market Impact
Historically bullish for equities over the medium term. The 2009-2015 ZIRP coincided with the S&P rising from 700 to 2100. The 2020 ZIRP produced a V-shaped recovery and then a historic rally.
10Y yields typically fall to 1.5-2.5% range, well below nominal GDP growth. The 2020 ZIRP saw 10Y bottom at 0.5%. TIPS real yields often go negative.
Duration-sensitive growth assets benefit disproportionately. QQQ outperformed SPY by wide margins during both ZIRP episodes as low discount rates boosted long-duration equity valuations.
Money-market yields fall to near zero, punishing savers. Households shift from deposits to equities and real estate, often creating asset-price distortions.
Dollar typically weakens at the announcement but the subsequent path depends on foreign policy. 2008-style ZIRP coinciding with global easing produces weaker dollar effects than US-specific ZIRP.
Gold rallies sharply at ZIRP implementation (2008, 2020). Real yields plunge and currency debasement concerns rise. Both episodes saw gold gain 50%+ over the subsequent years.
What to Watch For
- -Unemployment rising rapidly toward 8%+
- -Core inflation below 1% for sustained periods (disinflation risk)
- -Credit spreads blowing out above 700 bps (financial stress)
- -ISM Manufacturing below 40 confirming deep recession
- -Fed balance-sheet expansion announcement accompanying rate cuts
How to Interpret Current Conditions
ZIRP is only deployed in response to severe economic stress: financial crisis, pandemic, or prolonged recession. Watch the Fed funds futures curve for market expectations of Fed cuts and the 2Y yield as a market-implied forecast of rates 1-2 years forward.

Frequently Asked Questions
What triggers the "the Fed Cuts Rates to Zero" scenario?▾
The scenario activates when falls to 0-0.25%. The trigger metric and its current reading are shown on this page, so the live state of the scenario is always visible rather than abstract. Convex tracks this trigger continuously and flags crossings within hours.
Which assets are most affected when this scenario unfolds?▾
The Market Impact section lists the full asset-by-asset response, but the primary affected assets include: US Equities (S&P 500), Treasury Yields (10Y), Growth/Tech (QQQ), Savers (Money Market). Each asset has historically shown a characteristic pattern of response that is described in detail on the per-asset deep-dive pages linked below.
How often has this scenario played out historically?▾
The Fed took rates to 0-0.25% on December 16, 2008, and held them there until December 2015, seven years at the zero bound. The exit featured four rounds of QE (QE1, QE2, Operation Twist, QE3), forward guidance that evolved from calendar-based to state-contingent (tying rate hikes to unemployment and inflation thresholds). The 2020 ZIRP began March 15, 2020, with emergency 100 bp cut to zero, massive QE ($120B/month in Treasuries and MBS), and dovish forward guidance.

Inflation outcomes differed dramatically: 2008-era ZIRP never produced sustained inflation; 2020-era produced the worst inflation since 1982.
What should I watch for next?▾
The most important signals to track while this scenario is active: Unemployment rising rapidly toward 8%+; Core inflation below 1% for sustained periods (disinflation risk). The full list is on this page under "What to Watch For." These signals are the ones that historically preceded the scenario either resolving or accelerating.
How should I interpret the current state of this scenario?▾
ZIRP is only deployed in response to severe economic stress: financial crisis, pandemic, or prolonged recession. Watch the Fed funds futures curve for market expectations of Fed cuts and the 2Y yield as a market-implied forecast of rates 1-2 years forward.
Is this a prediction or a conditional analysis?▾
This is conditional analysis, not a prediction that the scenario will happen. Convex describes what typically follows once the trigger fires and shows how close or far the current data is from that trigger. The page is informational; it does not constitute financial advice.
