Bloomberg Economics has declared it officially: the 40-year era of low interest rates is over. In their new book "Money Shock," the Bloomberg team presents a detailed scenario where the US 10-year natural real interest rate — the so-called R* or neutral rate that balances saving and investment — bottomed at 1.7% in the mid-2010s, rose to 2.3% by 2022, and will peak at 2.8% by the 2030s. That would be the highest neutral rate since before the 2008 Global Financial Crisis. I've been watching this structural shift since the post-COVID inflation surge of 2021-2022, and I think the Bloomberg team is correct about the direction, though the exact magnitude and timing remain debatable.
The implications are profound. A 2.8% real neutral rate implies a nominal 10-year Treasury yield of 5.0-5.5% assuming 2.2-2.7% inflation — well above the 3.5-4.0% range that has prevailed for most of the past 15 years. For Korean investors, this means the era of "lower forever" that inflated asset prices across the board — from Seoul real estate to KOSPI growth stocks to bitcoin — is giving way to a regime where capital has a real cost again. Every asset class needs to be re-evaluated through this lens.
Eight Structural Drivers of a Higher-Rate World
The Bloomberg Economics team identifies eight structural forces pushing interest rates structurally higher. Let me focus on the most impactful ones for Korean and global investors.
Demographics. The baby boomer generation is entering retirement at accelerating rates, shifting from saving to spending. This reduces the economy's pool of savings and pushes rates up. The authors calculate that slowing population growth and declining dependency ratios lowered US natural real rates by about 1.35 percentage points between 1970 and 2011. That trend has now reversed — aging populations in developed economies are drawing down savings rather than accumulating them. This is happening in Korea even faster than in the US: Korea's working-age population peaked in 2016 and has been declining since, which means the savings pool that previously suppressed domestic interest rates is now shrinking.
Fiscal Dominance. US government debt has exploded from approximately 35% of GDP in 2007 to 95% in 2025, and is projected to exceed 105% by 2028, according to the Congressional Budget Office. When the government issues more bonds, bond prices fall and yields rise. This dynamic is the simplest structural pressure pushing rates higher. More supply of government bonds means higher yields to attract buyers, period.
AI and Productivity. Artificial intelligence is not just a stock market theme — it has real macroeconomic implications. If AI boosts productivity growth, corporate investment demand increases, which raises the demand for capital and pushes up interest rates. The Bloomberg team estimates that AI-related capital spending alone could add 30-50 basis points to neutral rates over the next decade.
Climate Transition. BloombergNEF estimates that the global transition to a net-zero economy will require over $30 trillion in investment — roughly 30% of 2023 global GDP. This massive capital mobilization will compete with other investment needs, further pressuring interest rates upward. For Korea specifically, the transition cost is enormous given the country's heavy reliance on manufacturing and energy-intensive industries.
Korea's Rate Path: Two More Hikes This Year
Korea is not immune to this global rate shift. Bank of Korea Governor Rhee Chang-yong held the base rate steady at 2.50% for the eighth consecutive meeting on May 28 but explicitly signaled that a July hike is coming. Market consensus based on Bloomberg interest rate swaps suggests two rate increases this year and one more in early 2027, bringing the base rate to a peak of 3.25%.
This would represent a dramatic departure from the zero-rate world that Korean borrowers have enjoyed for most of the past decade. Korean household debt stands at approximately 2,200 trillion won ($1.43 trillion), among the highest in the developed world relative to GDP. Every 25-basis-point hike adds roughly 5.5 trillion won ($3.6 billion) to household interest burdens. The debt service ratio — already near record levels at 12.5% of disposable income — would rise to approximately 13.8% under a 3.25% base rate, approaching levels that historically preceded consumer spending slowdowns.
The Bloomberg authors deliver a sobering warning that applies with particular force to Korea: "The most important price in the global economy — the price of money — is rising. And the cost of failing to adjust to this reality is also rising." I think this applies with particular force to Korea, where the property market (roughly 75% of household wealth is in real estate) and household leverage are extremely sensitive to rate changes.
Stablecoins: From Crypto Shelter to Global Payment Backbone
While interest rates dominate the macroeconomic narrative, a quieter but equally significant revolution is underway in the plumbing of the global financial system. Stablecoins — cryptocurrencies pegged to fiat currencies, usually the US dollar — have evolved from a niche tool for crypto traders into a serious contender for global payment infrastructure.
Hong Seok-won, a partner at Hashed, Korea's leading crypto venture capital firm with over $3 billion in AUM, laid out the thesis in a recent analysis: "Stablecoins were once seen as a shelter from crypto volatility or a tool relevant only within exchange ecosystems. Now they are rapidly ascending to become a core infrastructure of the global financial system." The numbers support his claim: the total market capitalization of stablecoins has surpassed $200 billion, and monthly transaction volumes now exceed $1 trillion — comparable to major payment networks like Visa.
The evidence of institutional adoption is mounting rapidly. PayPal issued its own stablecoin (PYUSD). Stripe acquired Bridge, a stablecoin platform, for $1.1 billion. Visa and Mastercard have integrated stablecoins into their settlement networks. Shopify now accepts USDC payments directly. Cross-border remittances and B2B settlements — long the domain of the slow, expensive SWIFT network, which typically takes 3-5 days and costs 3-7% in fees — are being disrupted by stablecoins that settle in seconds at near-zero cost.
Machine-to-Machine Payments: Stablecoins as the AI Economy's Settlement Layer
The most futuristic application of stablecoins may also be the most important. Hong argues that stablecoins will ultimately become the dominant settlement currency for machine-to-machine (M2M) payments — transactions between autonomous AI agents operating without human intervention.
Think about the problem: traditional payment rails — credit cards, bank transfers, SWIFT — were designed for humans. They require card approvals, account authentication, business hours, and human oversight for fraud detection. An AI agent executing hundreds of transactions per second would be crippled by these bottlenecks. Stablecoins, by contrast, operate 24/7, are programmable via smart contracts, and settle almost instantly. For an AI agent that needs to pay for API calls from OpenAI, compute resources from AWS, and data access from various providers, stablecoins are the only payment infrastructure that works at machine speed.
This is not science fiction. Coinbase has already demonstrated AI-to-AI crypto transactions. The infrastructure for an AI-agent economy — where autonomous software agents pay for services from other agents without human involvement — is being built right now, and stablecoins are the native settlement currency. I think the M2M payment market could be the killer use case that drives stablecoin adoption from speculative to utilitarian, unlocking a total addressable market worth trillions of dollars annually.
Regulation is catching up globally. The US GENIUS Act provides a comprehensive regulatory framework for stablecoins, bringing them into the regulated financial system. Japan has amended its Payment Services Act to permit stablecoin issuance by licensed entities. Korea is working on the second phase of its Digital Asset Basic Law, which will clarify issuance and distribution rules. Hong noted: "The market's question has shifted from 'how do we regulate crypto?' to 'how do we utilize it?'" In my view, Korea's ability to launch a won-pegged stablecoin could determine whether its fintech industry competes globally or remains a domestic player constrained by traditional banking infrastructure.
Korea's Think Tank Crisis: Zero S-Grades in National Research Evaluation
In a more parochial but no less significant development, Korea's 25 government-funded research institutes received their most damning evaluation in years. None received the top S-grade. Only five received A-grades: the Korea Institute for International Economic Policy (KIEP), the Korea Transport Institute, the Korea Institute for Health and Social Affairs, the Korea Research Institute for Human Settlements, and the Korea Legislation Research Institute.
The Korea Development Institute (KDI) — the flagship think tank that has shaped Korean economic policy for decades — received only a B-grade. Most shocking of all was the Korea Information Society Development Institute (KISDI), which received the lowest D-grade at a time when AI transformation has been declared a national priority by President Lee Jae-myung. The NRC evaluation panel criticized KISDI for failing "to present an integrated mid-to-long-term roadmap for strengthening industrial competitiveness spanning technology sovereignty, semiconductors, corporate transformation, regulation, and labor."
I think this evaluation matters for investors because it signals a potential vulnerability in Korea's policy infrastructure. If the country's top economic and technology researchers cannot produce actionable strategies — particularly on AI and semiconductors, where Korea competes directly with China, Taiwan, and the US — the risk of policy missteps increases materially. The evaluation also has direct financial implications: only institutes receiving B-grade or above receive performance bonuses, with institute heads receiving 37 million won ($24,000) at B-grade, adjusted by 7.5 million won ($4,900) per grade step.
Strategic Implications: Investing in a Higher-Rate World
The convergence of these three themes — structurally higher rates, stablecoin disruption of payment infrastructure, and Korea-specific policy challenges — has concrete implications for portfolio construction and investment strategy in the second half of 2026.
Cash is no longer trash. In a 2.50-3.25% base rate environment, money market funds and short-dated bonds offer positive real yields for the first time since 2021. The opportunity cost of holding cash has fallen dramatically. I would maintain a 10-15% cash allocation specifically for the purpose of deploying into distressed assets if the KOSPI selloff overshoots below 8,000.
Beware of duration risk. Long-dated bonds face significant headwinds if neutral rates are structurally higher than the pre-2020 era. The traditional 60/40 portfolio faces a more challenging environment than the post-2008 period of falling rates and quantitative easing. Consider barbelling short-dated bonds with selective equity exposure rather than holding intermediate-to-long duration.
Korea-specific positioning: Exporters benefit from both the weak won (now above 1,530) and the global AI capex cycle, but domestic-demand sectors — retail, real estate, consumer finance — face headwinds from higher rates and elevated household debt service burdens. Within the KOSPI, I think the bifurcation between exporters and domestic plays will widen in the coming quarters.
Monetary policy divergence: The BOK hiking toward 3.25% while the Fed potentially cuts or holds creates a narrowing interest rate differential that could actually support the won over a 6-12 month horizon. But that is a medium-term view — in the short term, capital flows and geopolitics dominate.
My Take
Recommendation: Neutral equities, overweight cash and short-duration bonds, selective exposure to AI infrastructure. The macro regime is shifting from the "lower forever" mindset that dominated markets for four decades to a higher-volatility, higher-rate equilibrium. This requires a fundamental rethinking of portfolio construction that many investors have not yet undertaken.
Specific actionable recommendation: Reduce exposure to long-duration assets (30-year bonds, high-multiple growth stocks with no earnings, long-dated real estate) by 15-20%. Increase allocation to floating-rate notes, money market funds, and short-duration investment-grade credit. For Korean investors specifically, consider won-denominated money market ETFs and export-oriented equities (semiconductors, shipbuilding, autos) as a hedge against the dual headwind of higher domestic rates and currency weakness. If you hold Korean bonds, stay in the 1-3 year part of the curve — the compensation for taking duration risk at current levels is inadequate.
Probability/Confidence: 75% that the 10-year US Treasury yield averages above 4.5% over the next 3 years. 60% that the Bank of Korea's base rate peaks at 3.25% or higher in this cycle. The wide confidence interval reflects genuine uncertainty about how the demographic and fiscal drivers will interact with AI-driven productivity gains.
Risk Warning: A sharp economic downturn could force central banks to cut rates aggressively, invalidating the higher-rate thesis. The Bloomberg Economics scenario assumes no deep recession. Additionally, stablecoin regulation remains fragmented globally — a major regulatory crackdown in the US or EU could slow or reverse the adoption curve, though the GENIUS Act passage suggests US regulators are taking a constructive approach. Finally, the think tank quality issue in Korea is a slow-burn risk, not a catalyst for immediate market action — it reduces Korea's policy optionality over time rather than triggering an identifiable event.
