This is a very practical question — and it touches how order execution and fund settlement actually work on the Nigerian market (Nigerian Exchange Group).
Let’s go straight to what happens.
🔍 Scenario you described
A system (broker/app) allocates shares to you, but you don’t complete the subscription (i.e., you don’t fund it or confirm it properly).
There are two possible situations, and the outcome depends on which one applies:
⚖️ 1. If it is a NORMAL MARKET BUY ORDER (secondary market)
This is the most common case when buying shares like:
GTCO
MTN Nigeria
What happens:
Your broker places a buy order
If your account is NOT fully funded, the order will:
👉 NOT execute at all
Outcome:
No shares allocated
No money deducted
Your funds remain in your brokerage wallet
If partially funded:
Order may be:
Partially filled, or
Completely rejected
👉 Any unused balance stays in your account
⚖️ 2. If it is a PRIMARY OFFER / PUBLIC OFFER / RIGHTS ISSUE
This is where your question becomes more relevant.
Examples:
IPO
Rights issue
Public offer subscription
🔴 Case A: You were ALLOCATED shares but didn’t complete payment
👉 This is rare today (because most offers require full payment upfront)
But if it happens:
Outcome:
Your allocation is cancelled
Shares are returned to the pool
You lose the allocation opportunity, NOT your money
🟡 Case B: You PAID but didn’t get full allocation (oversubscription)
This is very common.
Example:
You apply for ₦100,000 worth of shares
But due to oversubscription, you get ₦60,000 allocation
What happens:
👉 The remaining ₦40,000 is:
Refunded to your bank account or
Credited back to your brokerage wallet
⚠️ Important operational detail (Nigeria-specific)
Settlement is handled via:
Central Securities Clearing System
So:
If a trade is not executed → no settlement happens
If allocation fails → refund is processed via registrar/broker
💡 The REAL risk (what you should actually watch)
The only time you may have issues is:
1. Broker system delays
Refund may take:
24 hours (broker wallet)
3–10 working days (bank refund)
2. Unclear order status
“Pending” orders can confuse beginners
👉 Always check:
Order status: Executed / Pending / Cancelled
🔥 Simple rule (keep this)
❗ In Nigeria’s stock market:
No execution = no deduction
No full allocation = refund of balance
No completed subscription = no shares, but money remains yours
🎯 Practical advice for you
Given your current investing journey:
Always fund your brokerage BEFORE placing orders
Avoid “auto-allocation” systems you don’t fully understand
Start with small amounts until you understand execution flow
