Is the era of easily obtaining cryptocurrency profits officially over? A year ago, putting cash into stablecoins felt like finding a cheat code. Generous interest, ( was said to be ) zero risk. Today, this dream has turned to ashes.

The yield opportunities of stablecoins in the entire cryptocurrency sector have collapsed, leaving DeFi lenders and yield farmers trapped in a near-zero return wasteland. What has happened to that “risk-free” annual yield (APY) golden goose (money tree)? And who is to blame for the yield farming turning into a ghost town? Let's delve into the “autopsy report” of stablecoin yields, and it's not a pretty sight.

The dream of “risk-free” returns is dead.

Do you remember those wonderful old days ( around 2021 ) when various protocols were throwing out double-digit annual yields for USDC and DAI like candy? Centralized platforms expanded their managed assets ( AUM ) to huge levels in less than a year by promising stablecoin yields of 8-18%. Even so-called “conservative” DeFi protocols offered stablecoin deposit yields of over 10%. It was as if we had cracked the financial system, free money! Retail investors flocked in, convinced they had found the magical risk-free 20% yield on stablecoins. We all know how that ended.

Fast forward to 2025: this dream is on its last legs. Stablecoin yields have plummeted to single-digit lows or gone to zero, completely destroyed by a perfect storm. The promise of “risk-free returns” is dead, and it was never real to begin with. The golden goose of DeFi turned out to be just a headless chicken.

Token crash, profits collapse accordingly.

The first culprit is obvious: the cryptocurrency bear market. The drop in token prices has destroyed many sources of yield. The DeFi bull market was supported by expensive tokens; the 8% stablecoin yields you could earn before were possible because protocols could mint and distribute governance tokens that skyrocketed in value. But when these token prices plummeted by 80-90%, the party was over. Liquidity mining rewards have dried up or become nearly worthless. For example, Curve's CRV token was once close to $6 but is now hovering below $0.50—plans to subsidize yields for liquidity providers have completely fallen apart. In short, without a bull market, there are no free lunches.

Accompanying the price decline is a massive outflow of liquidity. The total locked value in DeFi (TVL) has evaporated from its peak. After reaching a peak at the end of 2021, TVL entered a downward spiral, plummeting over 70% during the crash of 2022-2023. Billions of dollars of capital have fled the protocols, either as investors stop-loss and exit or due to cascading failures that forced funds to withdraw. With half of the capital gone, yields naturally wither: fewer borrowers, reduced trading fees, and significantly decreased allocatable token incentives. The result is that DeFi's TVL ( resembles “total value lost”) and has struggled to recover to even a small fraction of its former glory, despite a mild rebound in 2024. When the fields have turned to dust, yield farms harvest nothing.

Risk appetite? Complete aversion.

Perhaps the most important factor stifling returns is simple fear. The risk appetite of the cryptocurrency community has plummeted. After experiencing the horror stories of centralized finance ( CeFi ) and the exit scams of DeFi, even the most aggressive speculators are saying “no, thank you.” Whether retail investors or whales, they have essentially sworn off the once-popular chase for yields. Since the disaster in 2022, most institutional funds have paused cryptocurrency investments, and those retail investors who were burned are now much more cautious. This mindset shift is evident: when a suspicious lending app could disappear overnight, why chase a 7% return? That saying “if it looks too good to be true, it probably is” has finally resonated deeply.

Even within DeFi, users are avoiding everything except the safest options. Leverage yield farming used to be the craze of DeFi summer, but now it has become a niche market. Yield aggregators and vaults are equally quiet; Yearn Finance is no longer a hot topic on crypto Twitter (CT). Simply put, no one has the appetite to try those exotic strategies anymore. Collective risk aversion is stifling the generous returns that once rewarded those risks. No risk appetite = no risk premium. What's left are only meager base interest rates.

Don't forget about the agreements: DeFi platforms themselves have also become more risk-averse. Many platforms have tightened collateral requirements, limited borrowing amounts, or closed unprofitable liquidity pools. After witnessing competitors suffer failures, protocols no longer pursue growth at all costs. This means fewer aggressive incentives and more conservative interest rate models, further squeezing yields.

The Revenge of Traditional Finance: Why Settle for 3% in DeFi When Government Bond Yields are 5%?

There's a ironic twist: the traditional financial world is starting to offer better returns than cryptocurrencies. The Federal Reserve's interest rate hikes have pushed the risk-free interest rate ( and the treasury yield ) close to 5% for 2023-2024. Suddenly, grandma's boring treasury yields surpass many DeFi pools! This completely upends the script. The entire appeal of stablecoin lending was that banks pay 0.1% while DeFi pays 8%. But when treasury bonds offer a zero-risk 5%, the single-digit returns of DeFi look extremely unattractive on a risk-adjusted basis. When Uncle Sam offers higher returns, why would a rational investor deposit dollars into a dubious smart contract to earn 4%?

In fact, this yield gap has siphoned capital away from the cryptocurrency space. Big players are starting to put cash into safe bonds or money market funds instead of stablecoin farms. Even stablecoin issuers cannot ignore this; they are beginning to invest their reserves in government bonds to earn substantial yields, most of which are being left by themselves. As a result, we see stablecoins idling in wallets, not being deployed. The opportunity cost of holding stablecoins with a 0% yield has become enormous, resulting in billions of dollars in lost interest. The dollars parked in “pure cash” stablecoins are doing nothing, while real-world interest rates are soaring. In short, traditional finance is stealing DeFi's lunch. DeFi yields must rise to compete, but without new demand, they cannot rise. So the funds just left.

Nowadays, Aave or Compound may offer around 4% annual yield on your USDC ( accompanied by various risks ), but the yield on a 1-year U.S. Treasury bond is about the same or even higher. The math is harsh: on a risk-adjusted basis, DeFi no longer has the ability to compete with traditional finance. Smart money knows this, and until the situation changes, capital will not rush back.

Token emissions under the agreement: unsustainable and coming to an end

Let's be honest: many lucrative returns were never real from the start. They were paid for through token inflation, venture capital subsidies, or outright Ponzi economics. This game can only last so long. By 2022, many protocols had to face reality: you can't sustain a 20% annual yield without blowing up during a bear market. We witnessed one protocol after another cut rewards or shut down projects because they were simply unsustainable. Liquidity mining activities were scaled back; as the treasury dried up, token incentives were reduced. Some yield farms literally exhausted the token emissions used for payments—the wells ran dry, and yield chasers moved on.

The prosperity of yield mining has turned into a downturn. The protocols that used to print tokens endlessly are now facing the consequences, with the token price plummeting to rock bottom, and the hired capital has long since departed.

In fact, the ride of easy profits has derailed. Crypto projects can no longer mint magic money to attract users unless they want to destroy their token value or incur the wrath of regulators. With new investors willing to mine and sell these tokens, ( cough cough, the number of investors ) is decreasing, and the feedback loop of unsustainable profits has collapsed. The only remaining profits are those truly supported by actual income ( transaction fees and interest margins ), and these profits are much smaller. DeFi has been forced to mature, but in the process, its yields have shrunk to realistic levels.

Yield Mining: A Ghost Town

All these factors come together to turn yield farming into a veritable ghost town. The vibrant farms and 'aggressive' strategies of yesterday feel like ancient history. Today, when browsing crypto Twitter, do you see anyone bragging about a 1000% annualized return or new farm tokens? Hardly. Instead, you see weary veterans and liquidity exit refugees. The few remaining yield opportunities are either tiny with high risks ( and therefore ignored by mainstream capital ), or so low they are numbing. Retail investors either let their stablecoins idle ( yielding zero but prefer safety ), or cash out into fiat and put their funds into off-chain money market funds. Big whales are making deals with traditional financial institutions to earn interest, or simply holding dollars, showing no interest in the yield game of DeFi. The result: farms lie barren. This is the winter of DeFi, and the crops aren’t growing.

Even in profitable places, the atmosphere has completely changed. DeFi protocols are now promoting integration with real-world assets (RWA) to barely achieve yields of 5% here and 6% there. Essentially, they are building bridges to traditional finance themselves – acknowledging that relying solely on on-chain activities can no longer generate competitive yields. The dream of a self-sustaining crypto yield universe is fading. DeFi is realizing that if you want “risk-free” returns, you will end up doing what traditional finance does ( buying government bonds or other physical assets ). Guess what – these yields hover in the mid-single digits at best. DeFi has lost its edge.

So our current situation is this: the stablecoin yields we knew are dead. A 20% annual yield is a fantasy, and even 8% is a thing of the past. We are faced with a sobering reality: if you want to achieve high returns in cryptocurrency now, you either take on insane risks ( with the corresponding possibility of total loss ), or you are chasing after something elusive. The average DeFi stablecoin lending rates can hardly exceed bank fixed deposit rates, if they can exceed them at all. On a risk-adjusted basis, DeFi yields are now simply laughable compared to other options.

There are no longer free lunches in cryptocurrency.

In the style of true doomsday prophecy, let us speak frankly: the era of easily obtaining stablecoin yields is over. The dream of risk-free returns in DeFi is not just dead; it has been murdered by a combination of market gravity, investor fear, traditional financial competition, vanishing liquidity, unsustainable token economics, regulatory crackdowns, and the stark reality. Cryptocurrency has gone through its wild west yield feast, ultimately ending in tears. Now, the survivors sift through the ruins, content with a 4% yield and calling it a victory.

Is this the end of DeFi? Not necessarily. Innovation always sparks new opportunities. But the tone has fundamentally changed. Returns in cryptocurrency must be earned through real value and real risks, not through magical internet money. The days of 'stablecoins yielding 9% because digital assets are going up' are over. DeFi is no longer a smarter choice than your bank account; in fact, in many ways, it is worse.

Provocative question: Will yield farming make a comeback, or is it just a fleeting gimmick of the zero interest rate era? The outlook seems bleak at the moment. Perhaps if global interest rates drop again, DeFi could shine once more by offering yields a few percentage points higher, but even then, trust has been severely damaged. It's hard to put the genie of doubt back in the bottle.

Currently, the crypto community must face a harsh truth: there is no risk-free 10% yield waiting for you in DeFi. If you want to earn high returns, you must invest capital into volatile investments or risk complex schemes, which is precisely what stablecoins were supposed to help you avoid. The entire point of stablecoin yields is to provide a return on a safe haven. This illusion has shattered. The market has awakened to discover that “stablecoin savings” is often a euphemism for playing with fire.

In the end, perhaps this liquidation is healthy. Eliminating false gains and unsustainable commitments may pave the way for more genuine, reasonably priced opportunities. But this is a long-term hope. The reality today is harsh: stablecoins still promise stability, but they no longer promise returns. The crypto yield farming market is declining, and many former farmers have hung up their work clothes. DeFi was once a paradise of double-digit returns, but now it is even difficult to provide treasury-level returns, and the risks are much greater. The crowd has noticed this, and they are voting with their feet ( and funds ).

Conclusion

As a critical observer, it is hard not to maintain a radical attitude intellectually: if a revolutionary financial movement cannot even outperform your grandmother's bond portfolio, what use is it? DeFi needs to answer this question, and until it does, the winter of stablecoin yields will continue to sharpen. The hype has disappeared, the yields have vanished, and perhaps the tourists have disappeared as well. What remains is an industry forced to confront its own limitations.

Meanwhile, let us mourn the narrative of “risk-free returns.” It used to be interesting. Now back to reality, stablecoin yields are actually zero, and the crypto world will have to adapt to life after the party is over. Be prepared accordingly, and do not be deceived by any new promises of easy profits. There is no such thing as a free lunch in this market. The sooner we accept this, the sooner we can rebuild trust, and perhaps one day, find real earnings rather than handouts.
