Citable research brief

Core conclusion · Tlines extraction

SMBC Nikko expects the US intraday repo market to grow to as much as $1 trillion, roughly one-third of overnight SOFR volumes, driven by efficiency gains in liquidity and collateral management, with rates likely below pro-rated overnight rates and capped by daylight overdraft charges, though operational issues can slow expansion.

Time horizon: medium-term

Key arguments

Intraday repo improves efficiency by smoothing funding liquidity troughs and allowing collateral reuse.
Demand is strong, but wider adoption requires operational development.
Banks can earn extra return on cash deposited at the Fed at end of day.
Borrowers may replace daylight overdraft credit with intraday repo.
Intraday repo rates may be below pro-rated overnight rates excluding late return fees.
Daylight overdraft charges are likely the ceiling for intraday repo rates.
Operational issues could slow expansion, including clearing and reporting.
Settlement failures could cause cascades of fails and surge in borrowing.

Key numbers

Projected intraday repo market growth: $1 trillion
Ratio of intraday repo to overnight SOFR: 1/3
Broadridge DLT repo average daily volume (April): $368bn/day
Fedwire average daily payments (June 2026): $5trn
Securities wire settlements: $2.8trn/day
US banks intraday liquidity need (2020): $630bn
Scaling to current Fedwire volumes: $1trn
Alternative estimate based on 15% shift: $200-500bn

Main risks

Operational issues may slow expansion of intraday repo.
Late returns could create cascades of fails and surge in borrowing.
Regulations focusing on end-of-day balances may miss intraday leverage build-up.
Central clearing platforms are still developing methods for netting.
Borrowers and lenders need precise forecasts of cash flow timing; inaccuracies pose risks.

Corresponding source evidence

Although intraday activity is light, we think this could grow to as much as $1trn or roughly 1/3 of overnight SOFR volumes. · medium-term
But while the demand to manage liquidity and collateral more efficiently is strong, wider adoption requires more operational development. · medium-term
Excluding “late return fees” we think the intraday repo rates might be below (pro-rated) overnight rates. · medium-term

Conditions / invalidation

operational development is resolved
excluding late return fees
if trades fail to unwind on time
if banks shift 15% of their traditional overnight repo to intraday tokenized repo
