NCD · Central Bank Bills
Negotiable Certificate of Deposit
Absorbs excess liquidity from the banking system. The 7-day KHR NCD max bid rate sets the corridor floor rate for interbank money market transactions.
Weekly · Thursday KHR & USD Floor Rate
Details

The NCD is a standardised central bank bill issued by the NBC to absorb excess liquidity from the banking system. NCDs are traded in secondary markets and are highly liquid, making them a low-risk asset for private financial institutions. They can also serve as collateral for LPCO, MLF, and overdraft transactions with the NBC.

MLF · Standing Lending Facility
Marginal Lending Facility
On-demand overnight collateralized lending at a fixed rate. Sets the ceiling of the interest rate corridor for interbank transactions.
On-Demand · 2× Daily KHR Only Ceiling Rate
Details

The MLF is an on-demand facility that provides short-term KHR liquidity to financial institutions at a fixed rate with overnight maturity (extendable upon request). Because institutions can always borrow from the NBC at the MLF rate, this rate functions as a hard ceiling for interbank money market rates.

OMO · Open Market Operations
Outright Purchase & Sales of Government Bonds
Fine-tuning day-to-day liquidity via secondary market transactions in short-dated government securities on the NBCP platform.
Day-to-Day Fine-Tuning
Details

The NBC conducts open market operations by buying or selling government bonds with market participants in the secondary market. OMO is used as a fine-tuning instrument to complement key weekly instruments and help meet operational liquidity objectives on a day-to-day basis. Currently, only securities with a remaining maturity of under 90 days are eligible.

Transaction typeOutright buy / outright sell
Eligible securitiesGovernment bonds with remaining maturity <90 days
FrequencyAs needed, day-to-day

RR · Structural Instrument
Reserve Requirement
Mandatory reserves held at the NBC. A structural tool that shapes medium-term liquidity conditions and supports KHR usage via an averaging framework.
Adjusted Infrequently Structural
Details

Reserve requirements oblige financial institutions to hold a specified portion of their deposits as reserves at the NBC. They serve both monetary policy and prudential purposes — influencing banks' lending and funding behavior over the medium term.

TypeMandatory reserves held at NBC
FrameworkAveraging — flexibility within maintenance period
Currency focusKHR (supports riel usage)
Adjustment frequencyInfrequent — structural decisions only
ImpactMedium-term lending capacity and funding behaviour
Dual purposeMonetary policy & prudential objectives
How it Works
Ongoing
Financial institutions maintain minimum average balance on reserve accounts at NBC
Period End
Compliance assessed over the maintenance period using averaging
Periodic
NBC may adjust reserve ratio in response to structural liquidity conditions
FX Spot · FX Intervention
Foreign Exchange Spot Intervention
Selective buy/sell of foreign currency to maintain orderly FX market conditions and support macro stability. Not a substitute for weekly operations.
Selective Use FX Stability
Details

The NBC may conduct FX interventions by buying or selling foreign currency to address excessive exchange rate volatility or disorderly market conditions. FX spot operations directly affect KHR liquidity in the banking system and are used selectively — not as a routine substitute for the NBC's weekly liquidity management tools.

Transaction typeFX spot purchase or sale of KHR
TriggerExcessive volatility or disorderly FX market conditions
Effect on liquidityDirectly affects KHR liquidity in banking system
FrequencySelective — not routine
ObjectiveExchange rate stability & macro prudential support
SubstitutionNot a substitute for weekly NCD/LPCO operations
Important Note

FX interventions are tools of last resort for maintaining orderly market conditions. They are not designed to target a specific exchange rate level or to replace the NBC's standard weekly liquidity management operations.

These instruments involve agreed exchanges of currencies at predetermined dates and rates — intended for liquidity management purposes, not as exchange-rate guarantees.

FX ForwardFixes an exchange rate and amount for future settlement
FX SwapCombines a spot leg with a forward leg
PurposeFX liquidity management & short-term currency mismatch smoothing
Not intended forExchange-rate level guarantees
