Nigerian Banks Pull N942 Billion From CBN Standing Deposit Facility as Excess Liquidity Position Shifts
Nigerian lenders cut the money they leave overnight with the Central Bank of Nigeria by N941.85 billion on October 7. Central bank data shows placements at the Standing Deposit Facility fell to N3.76 trillion from N4.70 trillion a day earlier. It was the biggest one-day reduction since September 30, when balances dropped by N1.73 trillion. The move is easy to miss next to the larger Open Market Operations numbers, but it shows how banks are handling their surplus cash after the biggest interest rate adjustment in years.
The Standing Deposit Facility works much like a savings window for banks. A lender with more cash than it needs for the day can leave it with the CBN overnight and collect interest, and the money comes back the next morning. Because the central bank pays the rate and carries the risk, there is no credit exposure and no hunting for a borrower. It is also one of the tools the CBN uses to keep surplus naira from spilling into the economy faster than it would like.
Banks had been using that window heavily for a few reasons. The first is the amount of cash in the system. Lenders hold large deposits, and a good share of them is already locked away by reserve requirements, which stay at 45 percent for commercial banks, 16 percent for merchant banks and 75 percent for non-TSA public sector deposits. The money left over still has to go somewhere each night. The second is the lack of attractive alternatives. Lending to businesses carries default risk, and the interbank market only pays well when someone is short of cash. When most banks have a surplus, nobody pays a premium to borrow, so the deposit window becomes the easy default.
The third reason is the rate on offer. Before the September 22 Monetary Policy Committee decision, the corridor around the policy rate sat at +50/-450 basis points. With the benchmark at 26.5 percent, that put the deposit rate near 22 percent. The CBN then cut the Monetary Policy Rate by 350 basis points to 23 percent and tightened the corridor to +50/-300, which sets the deposit rate at 20 percent and the lending rate at 23.5 percent. The central bank said one purpose was to bring the official rate back in line with what banks were actually charging each other. The overnight rate in the interbank market was already hovering around 22 percent, close to the old deposit rate, which meant the headline policy rate had stopped guiding anything.
So what does a N942 billion fall in placements tell us? On its own, it says the cash is no longer sitting at the central bank, but not where it went. The CBN publishes the balance, not the destination. Three explanations are plausible and they are not mutually exclusive. Banks may have used the money to pay for the Open Market Operations bills they bought at the October 6 auction, where the CBN took in about N3.31 trillion while about N2.17 trillion in older bills matured, a net drain of roughly N1.14 trillion. That figure is close to the N942 billion decline in deposits, though a rough match is not proof of cause. Banks may also have lent more to each other or bought other government securities. A smaller share may have gone into loans. Each of these is a legitimate use of surplus cash, and the data cannot separate them.
The September numbers add context. Balances at the facility reached N7.52 trillion on September 24, two days after the rate decision, then fell to N5.90 trillion the next day. They climbed back to N6.28 trillion on September 29, dropped to N4.55 trillion on September 30, and stood at N4.86 trillion on October 5. Seen against that path, the October 7 level of N3.76 trillion is exactly half the September peak. The swings are also worth noting. Day-to-day changes of more than a trillion naira show that banks are shifting large sums quickly, which fits a market adjusting to a new corridor and to heavy OMO activity. In September alone the CBN sold about N17.51 trillion in OMO bills against N10.89 trillion that matured, a net withdrawal of around N6.62 trillion.
There is a limit to the optimistic reading. N3.76 trillion remains in the facility, which is still a very large sum to leave idle overnight. The fall shows banks are not content to leave all their cash there, but it does not show they are now funding the real economy. The overnight financing rate was around 20 percent in early October, matching the deposit rate. Rates sitting at the floor of the corridor are what you would expect when there is plenty of cash and few buyers for it. If liquidity were genuinely tight, that rate would rise toward the 23.5 percent lending rate. It has not.
The next few weeks could reverse some of this. OMO maturities are projected to bring about N9.05 trillion back to banks and investors in October, roughly 68 percent of expected inflows for the month. When bills mature, cash returns to bank accounts, and some of it will probably find its way back to the deposit window unless the CBN sells enough new bills to absorb it. This is why the central bank keeps holding auctions at sizes that match or exceed maturities. Deposit balances will keep moving with those cycles, so a single day’s fall should not be treated as a trend.
For lending, the effect is indirect. Lower placements at the CBN free up funds that could support credit, but banks decide how to use them based on risk, not on what the central bank would prefer. Government securities still pay well, and with reserve requirements this high, the room for new loans is narrower than the headline liquidity suggests. The policy bet is that a lower deposit rate makes idle cash less rewarding and pushes banks toward customers who need funding. That bet will take months to test and will show up in loan approvals and lending rates, not in daily deposit figures.
Ordinary customers and business owners should keep a few points in mind. Nothing in these numbers points to stress at any bank. Movements in the facility are routine balance sheet management between institutions, and they do not affect the safety of personal or business accounts. It would also be a mistake to expect cheaper loans straight away. Banks reprice credit gradually, and many existing loans are tied to terms agreed before the rate cut. Companies planning to borrow may find lenders willing to negotiate as competition for good clients improves, but that is a conversation to have directly with your bank rather than something the central bank data guarantees.
Savers should expect returns on fixed-income products to drift lower over time as policy rates come down, even though current yields remain well above inflation. Inflation was 15.39 percent in August, so the real return on most government paper is still positive. The practical advice for anyone with a savings plan is to compare offers rather than assume rates will stay where they were earlier in the year.
The central bank’s next policy meeting is scheduled for November 23 and 24, and until then the weekly OMO auctions and the daily deposit balances are the clearest signals of how the CBN and the banks are positioning. Readers who follow the banking sector can find further coverage on Business Tech.
