Where did all the boring dollars go? How synthetics are turning stablecoins into green, lean, yield machines

If you thought studying the world’s idle capital was akin to watching paint dry, think again. There’s a new reality show on the blockchain called synthetic stablecoins, and it’s packed with action, intrigue, and more market moves than a Wolf of Wall Street outtake.

Remember the days when stablecoins were the dullest asset in the crypto casino: trusty, unyielding, digital seatbelts for the wild crypto ride? Well, that’s all changed. Now, the synthetic varieties are flipping the table and inviting everyone to the afterparty.

Synthetic stablecoins promise that your digital dollars won’t just sit around collecting dust (and regulatory side-eye), but actually work their flabby abs in the yield gym (even if it means surviving flashbacks to Terra/LUNA’s horror show).

What the heck are synthetic stablecoins, and why won’t they go away?

Forget parking your dollars in a basement vault. Synthetic stablecoins don’t settle for boring. Like something out of Hogwarts, they’re built using financial engineering wizardry. As Will Beeson, former head of Standard Chartered’s tokenization arm, and the CEO and founder of Uniform Labs, explains:

“Synthetic stablecoins, like Ethena’s USDe, are crypto-native, USD-pegged tokens that don’t rely on traditional fiat reserves held in banks. Instead, they use alternative yield-generation strategies.”

So, where does their value come from? Some pretty intense market choreography. As Beeson elaborates:

“USDe, for example, holds collateral in assets like staked Ether (e.g., stETH), then opens short positions in perpetual futures or derivatives to neutralize price volatility. This creates a “delta-neutral” position where gains from funding rates or basis spreads in derivatives markets generate yield, while the overall value stays pegged to $1.”

In English? It’s a financial see-saw. And if you’re wondering the need for all this [change this word: financial] gymnastics, the answer is simple: yield. Beeson shares:

“Synthetic stablecoins are gaining traction because they offer built-in yields, reaching up to 10–19% APY or more depending on the product.”

You read that right. Now compare that to the average US savings account APY in mid-2025, which sits around 0.45% according to the FDIC, and it’s not hard to see the appeal.

Not everyone’s cup of tea

Stablecoins started as a beacon of reliability: USDT and USDC are the ruling monarchs, with a kingdom spanning 85-90% of the market. With such high market dominance, it’s pretty clear that your garden variety stables serve the lion’s share of consumer needs. As Murray Neil Spark, Head of Commercial and Ecosystems at MiniPay non-custodial stablecoin wallet, confirms:

“[Synthetic stablecoins] are more focused on innovative financial engineering, and retail adoption remains limited compared to asset-backed stablecoins like USDT, which people already use for everyday transactions, even those unfamiliar with crypto.”

With a network of fiat on/off ramps across 40+ local currencies, MiniPay focuses on the latter, serving as a stable, reliable entry point with minimal friction. Spark continues:

“Yield-bearing synthetics are carving out a niche in the institutional and DeFi space, but asset-backed stablecoins remain the everyday digital cash for global last-mile users.”

And hey, someone’s got to hold the fort while synthetics party in the DeFi VIP room.

Synthetic stablecoins may not be for everyone. Those still reeling wth PTSD from previous imploded experiments may be better off staying away. Yet, the world’s thirst for yield remains real and indiscriminate. Beeson describes it as a “wall of idle capital,” expanding further:

“[There are] trillions in non-yielding assets – like the nearly $4 trillion in non-interest-bearing U.S. bank deposits and hundreds of billions in idle stablecoin balances – that are just sitting there, depreciating in real time.”

His point? With the GENIUS Act locking old-school stables in the zero-yield dungeon, all that cash is itching to break free.

Yield, baby, yield (but let’s not repeat the Terra trauma)

So what could possibly go wrong? Didn’t we already see the “magic money” stablecoin act collapse into a flaming $40 billion mess? Beeson insists this time it’s different.

“Terra/LUNA was an algorithmic stablecoin that relied on a seigniorage model, with UST’s peg maintained by arbitrage incentives tied to LUNA’s price, without overcollateralization or external hedges. It was fragile, and when trust eroded in 2022, a death spiral ensued as LUNA hyperinflated to mint more UST, wiping out $40 billion…

Modern synthetics like USDe use overcollateralized, delta-hedged positions backed by liquid crypto assets like ETH derivatives and diversified funding streams – not just internal token economics. USDe is transparent on-chain, with built-in risk controls like position limits and emergency mechanisms, with no single points of failure like Terra’s.”

And what’s more?

“Protocols like Ethena already manage billions without depegs.”

He concedes that many people are “still recovering” from their Terra/LUNA PTSD, but the lessons from that painful debacle have been learned. Three years on, regulations are clearer, models are proven, and the institutional capital is flowing back.

Colin Butler is EVP, Capital Markets, and Head of Global Financing at Mega Matrix, a publicly-traded company that recently filed for a $2 billion SEC shelf to fund a Digital Asset Treasury (DAT) fund. He seconds Beeson’s view about not comparing USDe to Terra.

“The risks are different. We are not worried about a death spiral algorithm. Here, the risks are mainly financial market risks that we understand. For instance, counterparty risk with exchanges, the funding rate turning negative for a prolonged period, or the underlying assets de-pegging, etc. But these are manageable risks…

…Sophisticated investors can see that the underlying mechanism is fundamentally different and grounded in established financial principles, not a purely algorithmic experiment.”

So, who’s actually using these things?

Who is throwing caution to the wind in the wild, wild race for yield? Turns out, not just your average sweatpants-wearing degen, but “trading desks and institutions that have to post collateral.” Butler puts it plainly:

“The choice between a 0% yield from a traditional stablecoin and a yield generated from a synthetic one is a powerful driver of adoption… As the market matures, we expect to see broader adoption from investors looking for dollar-denominated savings alternatives that are not stuck at zero yield.”

Meanwhile, Beeson emphasizes the “tens of thousands of holders across the globe using [USDe and sUSDe] for high-yield savings, staking for 10–19% APY.”

So, how do vanilla stablecoins compete against such attractive rates? Does this mean that Circle and Tether’s days are numbered? Well, not quite. Synthetic stablecoins are an acquired taste, while the traditional ones remain “foundational” according to Spark.

“Their liquidity, rails access, and brand trust underpin a lot of real-world flow.”

Regulations may be serving to box the bigger players in, but Beeson is clear on the important role they hold:

“Circle and Tether are not going away. They serve a critical function as on-ramps from traditional finance and are deeply embedded in market infrastructure. But their growth is constrained by their own model, especially as the GENIUS Act limits their ability to offer yield. So they have essentially become zero-yield dollars.”

The kingpins know it too; Circle is now a public company, Tether’s $500 billion IPO is coming up, and the company is rolling out USAT for U.S. compliance, all aiming to expand acceptance rather than cannibalize the flagship USDT.

The big players are not done yet, but expect them to run the nuts and bolts of tomorrow’s financial system rather than dance with hungry yield seekers.

The next move for all this bored capital

If there’s one thing everyone agrees on, it’s that money can’t stand being idle. So, where is it likely to flow? As Beeson points out:

“With the GENIUS Act banning yield-bearing stablecoins, this capital won’t stay put, as institutions can’t afford idle money in a global, real-time economy. It will likely flow into tokenized real-world assets (RWAs). We are already seeing massive growth in tokenized U.S. Treasury bonds and money market funds.”

With the tokenized RWA asset sector booming and projected to hit $30 trillion by 2034, the GENIUS Act has given it an extra push. If the digital dollar ever wants to win Best Supporting Asset, it’ll need to work harder for a living, funding flashier financial moves around the world.

Bottom line? If you want your stablecoins to join you in retirement, pick USDT or USDC. If you want your crypto dollars juiced up for action, synthetics may be calling your name. And if you just want to watch all the action, pull up a seat, keep the popcorn handy; the synthetic stablecoins soap opera is far from over.
