What it means
Bank accounts once lived in separate cages. Chequing paid nothing but moved money, savings paid interest but sat still, and the NOW account was the hybrid that broke the cages.
The name is the mechanism: a Negotiable Order of Withdrawal works like a cheque drawn on a savings account, so the balance earns interest while staying spendable. Massachusetts invented it quietly.
A mutual savings bank introduced the arrangement in the early 1970s, exploiting a rulebook gap, and the product spread until Congress legalised it nationwide in 1980. Regulation Q made it necessary, because Federal Reserve history records how interest rate ceilings banned interest on demand deposits and capped savings rates, and the NOW account was the industry's legal workaround.
The 1980 act ended the era. National authorisation of NOW accounts came with the phase-out of rate ceilings, and banks finally competed for transaction balances with interest.
The account type still exists formally, though modern transaction accounts descend from it, rate ceilings are long gone and the legal categories matter mostly to regulators and historians. The deeper legacy is the blurred line.
Money market accounts, sweep accounts and high-yield chequing all walk the path the NOW account cut between saving and spending. The workaround's economics were simple, since customers wanted one account doing both jobs and whoever supplied the hybrid pulled deposits from every rival still honouring the wall.
Regulators learned a durable lesson. Rules that forbid what customers plainly want breed ingenious evasion, and the ceiling era ended partly because the evasions kept winning.
For a business owner, the history explains your current menu, because interest-bearing operating accounts exist as one savings bank's workaround outcompeted a bad rule and the rulebook eventually surrendered. For today's treasurer, the descendants matter more.
Interest on operating cash is now a competitive given, and the treasury that leaves balances idle is paying a tax the 1970s would not have believed optional.
In practice
Real-world examples.
Example
A 1970s saver writes a negotiable order of withdrawal against an interest-paying account, legally, in one state. The saver pays the grocer with it as if it were a cheque while the balance keeps earning interest. One state ran the experiment, and the Northeast led the way.
Example
Congress authorises NOW accounts nationally in 1980 while scheduling the end of rate ceilings. Banks in every state can offer the product, and competition for transaction balances replaces the old ceiling on deposit interest. The ceilings fell with it.
Example
A modern sweep account moves a manufacturer's idle operating cash into an interest-bearing account each night and brings it back when payments are due. It descends from the same idea that spending money can also earn interest. Idle cash became a choice, not a rule.
Formula
Calculation
There is no single formula, only the hybrid test: pays interest x permits withdrawals on demand. Accounts passing both after 1980 were NOW accounts; before it, the combination was legally impossible nationwide.
The economics can be shown with simple interest: interest earned = average balance x annual rate x days / 365. Suppose a business keeps an average of $200,000 in an interest-bearing operating account paying an invented 2% for a 30-day month. Interest = $200,000 x 0.02 x 30 / 365 = $328.77. In a non-interest chequing account the same balance would earn $0, which is the idle-cash tax described above.Case study
Seen in the real world.
In this illustrative fictional case, Marguerite, a banking historian, traces her town's 1974 account ledgers at the Hillcrest Mutual Savings Bank. Its customers earn savings rates while writing negotiable orders at the grocer, years before competitors may. Her exhibit pairs a surviving withdrawal order with the 1980 statute, showing how a local workaround became national architecture. Visitors to the exhibit are surprised that something so ordinary was once illegal in most places. Marguerite adds a panel comparing the ledger with a modern business statement, so the story of the ceiling connects to the interest on idle balances that treasurers now take for granted.
Watch out
Common mistakes.
- Reading it as a modern product to shop for. The NOW account is a historical category, and today's equivalents are interest chequing and money market accounts.
- Confusing it with a savings account. The withdrawal instrument made it transactional, and that hybrid is precisely what the old rules forbade.
- Forgetting why it mattered. Rate ceilings once banned the combination, and the workaround's victory reshaped how all deposit money is priced.
Questions
People also ask.
What is a NOW account?
An interest-bearing transaction account built on the Negotiable Order of Withdrawal, a cheque-like instrument on savings. It combined earning with spending when the law tried to keep them apart.
Why was it invented?
Regulation Q's interest rate ceilings banned interest on chequing and capped savings. Federal Reserve history describes how the NOW account, born in Massachusetts, worked around the ban until Congress legalised it in 1980.
Does it still exist?
The legal category survives, but the ceilings are gone. Its descendants, interest chequing, money market and sweep accounts, are what customers actually shop among today.
