A SET50 stock's sector informs its indicative LTV band but never sets it: sector is shorthand for liquidity and volatility, so large-cap banks tend toward the higher end, commodity-exposed energy sits lower, and smaller property developers are sized more conservatively — yet the actual number always comes from the specific ticker.
Ask what loan-to-value a SET50 holding will support and the honest first answer is another question: what sector is it in? Not because the sector sets the number — it never does — but because sector is the fastest read on the two things a lender cares about most, liquidity and volatility. A deeply-traded, steady large-cap bank and a commodity-exposed refiner can sit in the same index and yet start from very different expectations about how much cash a lender will advance against them. This note walks through how sector liquidity and volatility shape indicative LTV bands across the SET50, using banking, energy, and property as the three worked examples — and it is careful to keep the figures where they belong: as relative bands, not precise promises. Consistent with the rest of this site, a real LTV in numbers is issued only after a principal reviews your actual ticker and position.
Key takeaways
- Sector informs LTV; it never sets it. The indicative band comes from the sector's typical liquidity and volatility, but the number comes from the specific ticker.
- Banks — deep float, heavy turnover, steadier prices — tend to sit toward the higher end of the range.
- Energy splits: regulated utilities are steadier, while commodity-exposed refiners and explorers carry sharper volatility and a lower band.
- Property is the widest spread of all: large developers and REITs can be solid; thinner small-caps are sized conservatively.
- We publish no fixed LTV percentages by sector. An indicative LTV follows review of the actual holding, typically within 2–3 business days.
How sector translates into an LTV band
The loan-to-value a share supports is a function of how safely a lender can hold it as collateral and, if it ever had to, realise it in an orderly way. Two characteristics dominate that judgement, and both are strongly patterned by sector:
- Liquidity. Deep free float and high average daily trading value mean a position can be managed and, if necessary, exited without crashing the price. The more liquid the sector's leading names, the higher the band they support.
- Volatility. The wider and more sudden a share's price swings, the larger the cushion a lender needs between the loan and the collateral value — which pulls the band lower. Steadier sectors support finer terms.
Because these two run along sector lines, sector is a legitimate shorthand for where a name is likely to start. But it is only a starting point. Free float, shareholder concentration, position size relative to volume, tenor, and recourse then move a specific holding up or down within its band. Sector sets the backdrop; the ticker decides the number. The cross-sector variables we weigh on every position are set out on the sectors page.
Banking & finance: the steady core
The large SET50 banks are, as a rule, among the most financeable shares on the exchange. They combine several things a lender values at once: substantial free float, heavy and consistent daily turnover, broad analyst coverage, and price behaviour that — while sensitive to interest rates and asset quality — is comparatively orderly rather than prone to violent gaps. That combination lets a lender hold the collateral comfortably and leave a relatively modest cushion, which is exactly what supports an indicative LTV toward the higher end of the range.
This does not make banks risk-free collateral. Earnings are cyclical, and a sector-wide shock — a sharp move in rates, or a deterioration in credit quality — moves the whole group together. But in the ordinary run of markets, a liquid large-cap bank is close to the reference point against which other sectors are judged.
Energy & utilities: a sector that splits in two
Energy is where a single sector label is most misleading, because the sector contains two quite different collateral profiles. At one end sit the large, regulated utilities — power generation and distribution with relatively predictable, policy-anchored earnings. These behave more like the steady end of the spectrum and can support a firmer band. At the other end sit the commodity-exposed names: refiners, and oil and gas explorers whose earnings and share prices move with crude prices, refining spreads, and policy decisions largely outside their control.
The index heavyweights in energy offer strong liquidity, so the exit is rarely the problem. The problem is volatility: a refiner can gap on a move in spreads or an oil-price shock, which thins the margin between loan and collateral value quickly. That sharper, more sudden price risk is why commodity-exposed energy names — even liquid ones — tend to be sized to a lower band than a comparably liquid bank. The lender is not doubting that it can sell the stock; it is protecting against how far the price can move before it does.
Property & construction: the widest spread
Property and construction shows the greatest internal variation of the three, which is precisely why the sector label tells you the least here. The sector spans large, liquid developers; REITs and infrastructure funds, whose unit behaviour differs from developer equity and is assessed separately; and a long tail of smaller developers with thinner free float, more cyclical earnings, and lower trading value.
A large, well-traded developer or an established REIT can present as solid collateral and sit in a respectable band. A smaller developer — cyclical, sensitive to interest rates and the property cycle, and lightly traded — is sized far more conservatively, because both its volatility and its thin liquidity argue for a wider cushion. In property more than anywhere, the right approach is to ignore the sector average and read the individual counter: its float, its trading depth, and how your position sits against normal volume.
| Sector profile | Typical liquidity | Typical volatility | Indicative band tendency |
|---|---|---|---|
| Large-cap banks | Deep | Moderate | Toward the higher end |
| Regulated utilities | Deep | Lower | Firm |
| Commodity energy (refiners, E&P) | Deep for majors | Higher | More conservative |
| Large developers / REITs | Moderate to deep | Moderate | Case by case |
| Smaller developers | Thinner | Higher, cyclical | Conservative |
The table describes tendencies, not tariffs. It is a way of seeing why a bank and a refiner start from different places — not a schedule you can read your own LTV off. Two names in the same row can still price differently once free float, concentration, and position size are taken into account.
We do not publish fixed LTV percentages by sector, because a single headline figure would be wrong for most of the positions inside that sector. The honest unit is a relative band, and the real number waits for the ticker.
Where the SET50 label helps — and where it doesn't
Membership of the SET50 is a genuinely useful signal. Index heavyweights are, by construction, the largest and most liquid names on the exchange, and they typically qualify most readily and on the strongest terms. But the index tells you a stock is large and liquid, not that it is steady. A volatile, commodity-driven SET50 name can be sized more conservatively than a calmer large-cap that happens to sit just outside the index. Liquidity gets a name into the conversation; volatility and the specifics of your holding decide where in its band it lands.
What moves a position within its band
Once sector has framed the starting point, the position-level factors do the rest of the work — and they are the same in every sector. The table below sets out which factors push a holding toward the higher end of its band and which pull it toward the lower, more conservative end.
| Pushes toward the higher end | Pulls toward the lower end |
|---|---|
| Deep liquidity | Thin trading |
| Steadier volatility | Sharp price swings |
| A wide free float | A tight float |
| A position that is small relative to daily volume | A holding that represents many days of volume |
Tenor and recourse offer further room to optimise: a shorter tenor and a measure of recourse can also improve the terms. This is why we treat every enquiry as a specific case: the sector is the map, but your ticker is the territory.
How we set the actual number
To see how these factors interact before you enquire, try our illustrative indicative LTV calculator — pick a sector and set the liquidity, volatility, concentration, tenor, and recourse to see where the range might sit. It is an illustration only, never a quote, and always returns a range rather than a single number.
None of this is quoted blind. When you share the ticker, the size of your position, and the structure you have in mind through our process, a principal reviews the live liquidity, volatility, float, and concentration picture, places the name against its sector backdrop, and returns an indicative LTV and loan amount — typically within two to three business days. Transactions are generally structured from THB 30 million upward. From there the structure is refined, including any board or NVDR considerations, before anything is documented. Definitions for the terms used here are in the glossary.
