Who really controls the money?

Most people imagine billionaires run the financial world. The reality is stranger.

Retail investor$10,000
Millionaire$10,000,000
Family office$1,000,000,000
Sovereign wealth fund$100,000,000,000+
BlackRock$14,000,000,000,000+

These steps span nine zeros — each is roughly 100 to 1,000 times the one above. Written out in full, the length of each number shows the jump.

The surprising part

Most of that money isn't BlackRock's. It's other people's — millions of ordinary savings, pooled and passed up the chain.

The flip

The world's biggest pools of money are mostly aggregated savings — yours included.

In Singapore, your CPF savings flow into special government securities that GIC invests worldwide — the same pooling, closer to home.

Why capital flows

Money never sits still. It hunts for the best return it can find — and runs from danger.

Capital — money looking to grow — constantly moves toward opportunity and away from risk. It flows to the companies and countries that offer the best return for the risk taken, and flees those that don't. Understanding why it moves explains booms, busts, and which businesses ever get built.

Where capital goes

It weighs reward against risk — then moves.

What attracts it

Return + safety

Growth, profits, stability, and the rule of law pull capital in.

What repels it

Risk + better deals

Instability, poor returns, or a better option elsewhere send it fleeing.

Insider tell

Capital is both a coward and an opportunist: it flees at the first hint of danger and crowds in wherever it's treated well.

Capital goes where it's welcome and stays where it's well treated.

Investment banks

The dealmakers who help giants raise money and buy each other.

An investment bank doesn't take your deposits. It advises big companies and governments: running IPOs, arranging mergers and acquisitions (M&A), and trading at a massive scale. Goldman Sachs, Morgan Stanley and J.P. Morgan are the famous names.

Three things an investment bank does

All of them earn a slice of very big deals.

M&A

Mergers

Advising on companies buying or merging with each other.

The fee

A slice of billions

Even a small % of a giant deal is an enormous payday.

Money is always there but the pockets change.

Gertrude Stein, writer

Hedge funds

The secretive, high-powered funds that try to make money whether markets go up — or down.

A hedge fund pools money from the very wealthy and big institutions, then makes bold, often complex bets. The name comes from hedging — placing bets in both directions so the fund can profit, or at least survive, in any market.

The core trick: betting both ways

Most investors only win when prices rise. A hedge fund can also win when they fall.

Who can invest?

Not you

Open only to the wealthy and big institutions — by law.

The classic fee

2 & 20

2% of your money a year, plus 20% of any profit.

Diversifying well is the most important thing you need to do in order to invest well.

Private equity

Buy a whole company, fix it up, sell it for more.

Private equity firms raise huge funds, buy entire companies (often with borrowed money), spend a few years making them more profitable, then sell them at a gain. Done well, it revives businesses; done badly, it loads them with debt. Blackstone, Apollo and KKR are the giants.

The private-equity cycle

Raise, buy, improve, sell — then do it again.

Leverage

Borrowed money

Buying with debt magnifies the gain — and the risk.

The exit

Sell high

The whole game is selling the fixed-up company for more.

The one number

~12 million

Americans now work for companies owned by private equity — you’ve probably shopped at one this week without knowing.

It's as easy to do something big as it is to do something small, so reach for a fantasy worthy of your pursuit.

Stephen Schwarzman, founder of Blackstone

Venture capital

Betting small sums on wild ideas, hoping one becomes the next giant.

Venture capitalists fund young, risky startups in exchange for a chunk of ownership. Most of their bets fail — but the rare winner (an Amazon, a Grab) can return the entire fund many times over. It's the money behind almost every tech company you use.

The power law

Most bets lose; one giant winner pays for them all.

Power law

One winner

A single huge success can outweigh dozens of failures.

Equity stake

Own a slice

VCs take ownership, not repayment — they win only if you do.

The one number

~3 in 4

Venture-backed startups that never return investors’ cash. The rare giant winner pays for all the failures.

The biggest risk is not taking any risk.

Private credit

The fast-growing world of lending that isn't done by banks.

Since banks pulled back after the 2008 crisis, investment funds have stepped in to lend directly to companies — that's private credit. It's fast and flexible for borrowers, and pays lenders high interest. It's grown into a multi-trillion-dollar industry led by firms like Apollo and Ares.

Bank loan vs private credit

Borrowers trade a higher rate for speed and flexibility.

Why it boomed

Banks retreated

After 2008, stricter rules pushed lending to private funds.

The trade

Pay for speed

Borrowers accept higher rates to get money fast, with fewer strings.

Neither a borrower nor a lender be.

Asset managers

The quiet giants who invest everyone else's money — and own a piece of almost everything.

Asset managers invest money on behalf of millions: pension savers, funds, institutions. The biggest, BlackRock, manages over US$14 trillion. Through index funds, firms like BlackRock and Vanguard are among the largest shareholders in most big companies on earth.

The giant funnel

Millions of savers in; ownership of thousands of companies out.

Index funds

Cheap & broad

Funds that simply track the market made investing nearly free.

Quiet power

They vote

As huge shareholders, they have a say in most big companies.

Time in the market beats timing the market.

Investing adage

Sovereign wealth

When entire countries become investors.

Some governments save their surpluses — from oil, exports, or reserves — in giant investment funds called sovereign wealth funds. Norway's Norges Bank Investment Management (NBIM), built on oil, holds over US$2 trillion. Singapore runs two of the most respected: GIC (which invests the reserves) and Temasek (which owns stakes in companies).

Turning a surplus into the future

Today's spare money, invested for tomorrow's income.

Singapore's two

GIC & Temasek

GIC invests the reserves (~$800B); Temasek owns companies (~$300B).

Why bother

A national nest egg

Turn today's one-off surplus into investment income that funds the country for generations.
