EDITOR NOTE: Unverified items: (1) the 2022/23 corridor settings (bank rate 8.5 percent, policy rate 7.0 percent, deposit collection rate 5.5 percent) come from secondary reporting of NRB’s 2022/23 monetary policy; confirm against the NRB document; (2) the corridor’s start date is reported as the 2016/17 monetary policy (Kathmandu Post, August 10, 2016; The Himalayan Times) but Nepal News dates it to July 2017; confirm with NRB; (3) the January 2024 floor touch at 3 percent is from ShareSansar only; (4) confirm NRB has not changed any corridor rate since the July 7, 2026 policy (the first-quarter review is due soon).
Every July, the headline from Baluwatar is the same kind of sentence: “NRB keeps policy rate at 4.25 percent.” Most investors read that number as the price of money in Nepal. It is not. In mid-August 2026, according to Nepal Rastra Bank’s own monthly data, banks were lending to each other overnight at a weighted average of 2.75 percent. Not 4.25. A full one and a half points lower.
That gap is the most useful thing you can learn about the NRB interest rate corridor. The corridor is the band NRB draws around short-term interest rates: a floor, a ceiling, and a policy rate in the middle. The announced policy rate gets the headlines. But where the market rate actually sits inside the band tells you far more about bank deposit rates, lending rates, and the liquidity that flows into NEPSE. Right now the market is pinned to the floor, and that is the real monetary policy.
What the NRB interest rate corridor actually is
Think of the corridor as two doors that NRB keeps open every day for banks and financial institutions (BFIs).
The lower door is the standing deposit facility (SDF). A bank with spare cash at the end of the day can park it with NRB and earn the SDF rate. Because that option is always there, no sensible bank will lend to another bank for less. The SDF rate is therefore the floor of the corridor.
The upper door is the standing liquidity facility (SLF), whose rate NRB calls the bank rate. A bank short of cash can borrow from NRB against eligible collateral at that rate. Because that option is always there too, no bank should pay another bank more than the bank rate. That is the ceiling.
In between sits the policy rate, which NRB announces as its signal and which also serves as its repo rate when it injects money through auctions. NRB’s stated operating target is the weighted average interbank rate, the rate at which BFIs lend to each other overnight. The idea is that NRB uses its daily tools (deposit collection auctions, repo, reverse repo and NRB bonds) to keep the interbank rate near the policy rate, with the two doors catching anything that drifts too far.
For fiscal year 2026/27, according to NRB’s monetary policy announced on July 7, 2026 (as reported by Nepal News and The Himalayan Times), the settings are unchanged from last year:
- Floor (standing deposit facility rate): 2.75 percent
- Policy rate: 4.25 percent
- Ceiling (bank rate, standing liquidity facility): 5.75 percent
That is a corridor 3 percentage points wide, with the policy rate 1.5 points above the floor and 1.5 points below the ceiling.
How Nepal got here
Nepal did not always steer money this way. For years NRB targeted quantities, mainly reserve money and money supply growth, and let short-term interest rates swing with liquidity.
According to The Himalayan Times and a January 23, 2018 commentary by an NRB Research Department official in the same paper, the corridor was announced in NRB’s 2016/17 monetary policy, with the Kathmandu Post reporting its implementation in August 2016. In that first version, the floor and the ceiling both floated with market rates, which defeated much of the purpose. The 2017/18 policy fixed both ends. The same NRB official wrote that the repo rate, then used as the policy rate, was fixed at 5 percent, with banks able to deposit spare money at NRB at 3 percent.
Since then, the band has moved with the cycle. During the 2022/23 tightening, according to reports of that year’s monetary policy, NRB raised all three rates by 1.5 points, taking the bank rate to 8.5 percent, the policy rate to 7.0 percent and the deposit collection rate to 5.5 percent. As inflation eased and liquidity piled up, NRB cut step by step to today’s 2.75, 4.25 and 5.75 percent.
The mechanism is now nearly a decade old. What has changed is which edge of the corridor matters.
A worked example: what the two doors cost
Abstract rates hide the incentives, so put numbers on them.
Imagine a commercial bank with NPR 10 crore of spare cash at the close of business. It has two choices tonight. It can lend the money to another bank in the interbank market, or it can park it with NRB through the standing deposit facility at 2.75 percent.
At 2.75 percent a year, NPR 10 crore earns about NPR 7,534 overnight (NPR 10 crore multiplied by 2.75 percent, divided by 365). That is the guaranteed, risk-free fallback. If another bank offers 2.60 percent, the lender refuses and goes to NRB. So 2.75 percent becomes the effective minimum for overnight money.
Now flip it. A different bank is NPR 10 crore short. If no one will lend to it, it can borrow from NRB’s standing liquidity facility at 5.75 percent, which costs about NPR 15,753 for the night. Any bank asking more than 5.75 percent in the interbank market gets turned down, because NRB’s window is cheaper.
So the overnight price of NPR 10 crore in Nepal right now can only move between roughly NPR 7,500 and NPR 15,800 a night. That is the corridor in practice. The question that matters is where in that range the market is trading. And the answer, in 2026, is at the very bottom.
Why the interbank rate is stuck to the floor
When a corridor works as designed, the interbank rate hovers near the policy rate. When the banking system is drowning in cash, every bank is a lender and almost none is a borrower. Nobody bids above the floor, so the market rate collapses onto it.
That is exactly Nepal’s situation. According to NRB’s report on the current macroeconomic and financial situation, based on data to mid-August 2026, the weighted average interbank rate stood at 2.75 percent in the first month of 2026/27, the same as a year earlier. That is precisely the SDF rate. The same report shows that in that single month NRB absorbed NPR 2,273.30 billion of liquidity on a transaction basis, including NPR 1,893.80 billion through the standing deposit facility and NPR 379.50 billion through deposit collection auctions. Outstanding liquidity-absorbing instruments stood at NPR 1,265.80 billion in mid-August 2026, including NPR 400 billion of NRB bonds.
The surplus is not new. NRB’s Macroeconomic Report published with the July 2026 policy, as summarized by Nepal News, put excess reserves in the banking system at roughly NPR 1.1 trillion by mid-May 2026. Remittances keep pouring in (NRB reports a 21.2 percent rise in NPR terms in the first month of 2026/27), deposits keep growing, and private sector credit is growing slowly, at 7.0 percent year on year to mid-August 2026 by NRB’s count.
When banks cannot lend the money out, they hand it back to NRB at the floor. The corridor has quietly turned into what economists call a floor system. NRB’s own July 2026 analysis, as reported by Nepal News, describes the interbank rate as having largely tracked the floor over the past year.
This has happened before. ShareSansar reported in January 2024 that the interbank rate had touched the floor (then 3 percent) after a period of heavy liquidity withdrawal by NRB. Nepal’s money market swings between the edges far more often than it rests in the middle.
The take: the policy rate is the wrong number to watch
Here is the argument, and it is a firm one. For as long as the interbank rate sits on the SDF floor, the 4.25 percent policy rate is a signal, not a price. The rate that actually governs what a bank can earn on idle money is 2.75 percent. A cut or hike to the policy rate alone, with the floor left untouched, would change very little in practice. A change to the floor would change a lot.
That has three consequences that headline coverage rarely draws out.
First, the floor quietly sets deposit rates. If a bank’s alternative use for spare cash is NRB at 2.75 percent, it has little reason to pay savers much more for fresh deposits it cannot lend. NRB’s data show commercial banks’ weighted average deposit rate fell to 3.15 percent in mid-August 2026, from 4.02 percent a year earlier. Their weighted average lending rate fell to 6.48 percent from 7.76 percent, and the average base rate to 4.72 percent from 5.78 percent. Those are not coincidences. They are the floor working its way through the system.
Second, a cheap floor does not guarantee lending. NRB’s own analysis, as reported by Nepal News, calls this a “credit conundrum”: record-low rates, a mountain of excess liquidity, and private credit growth of around 6 percent in 2025/26 against a 12 percent projection. NRB lists four reasons: capital adequacy constraints at most banks, the credit-to-deposit ratio binding at some, rising bad loans, and a weak real estate market that underpins most collateral. The corridor can make money cheap. It cannot make banks willing to lend or borrowers willing to borrow. That is the limit of the tool, and investors who expect every rate cut to lift bank earnings ignore it.
Third, the real tightening signal arrives before any announcement. The moment the interbank rate lifts off 2.75 percent and starts drifting toward 4.25, the surplus is draining. That usually happens before NRB moves any rate, because it reflects real flows: a credit pickup, government cash piling up at NRB, a drop in remittances, or seasonal pressure. Our explainer on the Asar-end banking crunch shows how quickly that can happen near fiscal year-end. An investor watching only the July headline will see it months late.
Why the policy rate still matters (the fair counter-argument)
It would be wrong to say the policy rate is meaningless. Two points cut the other way.
The policy rate is still NRB’s repo rate, the price at which it injects liquidity through auctions when the system tightens. If the surplus drains, the policy rate becomes the anchor again almost overnight. It is also the stance signal: banks, rating agencies and borrowers read it as NRB’s view on inflation and growth.
The corridor’s width also matters. A 3-point band gives NRB room but also lets market rates swing widely before either door catches them. The 2018 NRB commentary in The Himalayan Times made this point directly: a wide corridor can encourage banks to hoard liquidity, while a narrow one can discourage interbank trading and push banks onto the central bank’s window. So the right reading is not “ignore the policy rate.” It is “read the policy rate together with where the interbank rate sits, and treat the gap as information.”
Transmission: why your loan does not move when NRB does
Even when NRB moves the corridor, the effect on your home loan or fixed deposit is partial and slow. According to Nepal News’ summary of NRB’s July 2026 Macroeconomic Report, NRB’s research estimates pass-through from the policy rate to bank rates at about 0.5, meaning roughly half of a move eventually shows up in retail rates. Term deposits are named as a main source of friction, because banks cannot quickly reprice money they have already locked in at fixed rates.
That friction is shrinking in an unusual way. NRB’s data show fixed deposits fell from 48.4 percent of total BFI deposits in mid-August 2025 to 35.6 percent in mid-August 2026, while savings deposits rose from 37.5 percent to 47.6 percent. Savings accounts reprice faster. If that shift holds, the next corridor move should reach depositors and borrowers more quickly than past ones did. That is our reading of the data, not an NRB projection.
For bank shareholders, this cuts both ways. Cheaper, faster-repricing deposits help margins when rates fall, which is why the CASA ratio is worth tracking bank by bank. But lending rates are repricing down too, and a bank sitting on surplus cash parked at 2.75 percent is earning very little on it. Our guide to base rate and spread in Nepali banks walks through how that squeeze shows up in quarterly results.
What the corridor means for NEPSE
The link between the corridor and share prices is indirect, and investors often overstate it. Lower rates do not lift every stock. But three channels are real.
The first is the opportunity cost of saving. When commercial bank deposit rates average 3.15 percent and inflation was 5.96 percent year on year in mid-August 2026 (both from NRB), a fixed deposit loses purchasing power. That pushes some savers toward equities and dividend stocks. It is a reason money flows to NEPSE, not a reason any particular stock is cheap.
The second is margin lending. Share-backed loans get cheaper when bank rates fall, and that leverage tends to amplify both rallies and selloffs. A floor-bound corridor keeps that fuel cheap, but bank appetite and NRB’s own margin lending rules decide how much of it actually reaches the market.
The third is bank earnings, since banks and financial institutions dominate the index. According to NRB, BFIs and insurers made up 50.9 percent of NEPSE market capitalization in mid-August 2026. When the floor is low and credit is weak, bank profits face pressure from thin earnings on idle liquidity, falling lending yields and rising bad-loan provisions. Cheap money is not automatically good news for the sector that makes up half the index.
Note what has not happened. Despite the floor-bound corridor and abundant liquidity, NRB’s data show the NEPSE index at 2,643.84 in mid-August 2026, below the 2,788.37 of a year earlier. Cheap money is a tailwind, not a guarantee.
How to read the corridor yourself
You do not need a terminal. NRB publishes almost everything an investor needs.
- Read the three rates from the monetary policy each July, and check the mid-term review for changes. Our guide on how to read NRB’s monetary policy shows where to find them.
- Check the weighted average interbank rate in NRB’s monthly “Current Macroeconomic and Financial Situation” report. Compare it with the floor and the policy rate.
- Look at liquidity absorbed or injected in the same report. Large SDF and deposit-auction numbers mean surplus. Repo injections and SLF use mean stress.
- Watch deposit and lending rates in the same table. If the interbank rate rises but bank deposit rates have not, expect them to follow within a few months.
The single signal worth putting on your calendar is the gap between the interbank rate and the floor. At zero, money is abundant and deposit rates will stay low. As the gap widens toward the policy rate, the surplus is draining, and banks will start competing for deposits again.
The verdict
The NRB interest rate corridor is a sound design, and nearly a decade in, it does its basic job: it keeps overnight rates inside a band NRB controls. But in 2026 the band is not being used the way its name suggests. With the interbank rate sitting at 2.75 percent, the floor is doing the work and the 4.25 percent policy rate is mostly a message.
So stop reading NRB’s July announcement as “the price of money.” Read the floor as the price, the policy rate as the intention, and the distance between the interbank rate and the floor as the early warning. The day that distance starts to grow, deposit rates, bank margins and NEPSE liquidity will all change, whether or not the headline rate has moved.
This is analysis, not financial advice.
