A Country That Has Been Mining Bitcoin for 8 Years Establishes Its Own Dedicated Crypto Bank

Bhutan, a small Himalayan nation known for prioritizing Gross National Happiness over GDP, has established a dedicated crypto bank after eight years of Bitcoin mining. The DK Bank, located in the Gelephu Mindfulness City (GMC) Special Administrative Region, aims to fill the persistent banking gap for the crypto industry. Unlike traditional banks that often reject crypto firms or only handle their fiat transactions, DK Bank offers integrated multi-currency accounts where users can manage both fiat currencies and stablecoins like USDT and USDC, alongside services such as Bitcoin-backed loans. The bank operates under a unique "one country, two systems" governance model in GMC, which is designed to become a financial hub for South Asia. Its regulatory framework is modeled on Singapore's common law and Abu Dhabi Global Market's (ADGM) rules, offering a fast-track licensing process for firms already licensed in those jurisdictions. DK Bank and GMC authorities emphasize stringent, real-time on-chain and off-chain transaction monitoring to mitigate risks associated with anonymity in crypto. This move is part of Bhutan's longer-term strategic pivot toward institutional crypto services—including mining, custody, and asset management—rather than retail-focused speculative tokens. Officials stress diversification within the blockchain ecosystem to hedge against volatility in assets like Bitcoin. The development of supporting infrastructure, including an international airport managed by Singapore's Changi operator, is ongoing, with completion targeted for 2029. The initiative represents Bhutan's attempt to position itself at the forefront of the shift of global financial services on-chain, leveraging its early experience and a stated ethos of orderly and mindful progress.

Market Trends in US Stocks (June 18): Walsh's Pivot Ignites Broad Sell-Off, SpaceX Suffers First Drop, Semiconductors Sole Safe Haven

**U.S. Market Trends (June 18): Wash Sparks Full-Scale Sell-off; SpaceX's First Drop, Semiconductors the Only Safe Haven** Markets plunged after the June FOMC meeting. The "dot plot" revealed a hawkish shift, with half the officials projecting at least one rate hike in 2024. New Fed Chair Wash, in his press conference, announced the abandonment of forward guidance, stating he "can't tell you what the next step will be." This policy uncertainty triggered a broad sell-off. All major indices fell over 1%, with the S&P 500 down 1.21%. The VIX volatility index jumped 12%. Treasury yields spiked, and the dollar surged to a two-month high, while gold erased its weekly gains. The sell-off was led by rate-sensitive sectors. Meta plunged over 5%, leading the Magnificent 7 lower. SpaceX closed down ~5%, marking its first decline since its IPO, as valuation pressure from higher rate expectations took hold. The sole market bright spot was semiconductors. The Philadelphia Semiconductor Index rose 1.38%, with Applied Materials, Lam Research, and Arm Holdings all posting significant gains. The narrative held that long-term AI computing demand remains intact, driving a rotation of funds from high-valuation software/internet stocks into infrastructure and equipment names. Retail sales data came in strong, and EIA crude inventories fell sharply, supporting the view of persistent inflation and limiting the Fed's scope for easing. Traders fully priced in a rate hike by October, with September seen as likely. In summary, Chair Wash's debut dismantled the market's traditional policy anchors, injecting new uncertainty. While the AI investment thesis provided pockets of resilience in semiconductors, the repricing of rate-sensitive, high-valuation technology stocks appears to have just begun under the new "hawkish reset" framework.

3B Small Model's Programming Scores Rival Opus 4.5, Mysterious Model Sparks Heated Discussion, Turns Out to be Domestic

A 3B parameter dense reasoning model named VibeThinker-3B has gained significant attention for achieving performance comparable to leading models like Gemini 3 Pro, GPT-5 high, and Claude Opus 4.5 in verifiable reasoning tasks such as programming, mathematics, and STEM problem-solving, despite its significantly smaller size. Developed by Sina Weibo's team, the model is built upon Qwen2.5-Coder-3B. Its training employs an upgraded Spectrum-to-Signal pipeline, featuring a curriculum-based two-stage supervised fine-tuning (SFT), multi-domain reinforcement learning (RL) inspired by MGPO, offline self-distillation, and instruction RL to enhance controllability. A key innovation is the Claim-Level Reliability (CLR) assessment, a test-time scaling strategy that further boosts performance on math benchmarks. The model excels in specific, verifiable domains, scoring highly on tests like AIME26 (94.3/97.1 with CLR) and LiveCodeBench v6 (80.2 Pass@1). However, it performs less impressively in areas requiring broad general knowledge. The authors propose a "parameter compression coverage hypothesis," suggesting that verifiable reasoning abilities—reliant on multi-step logic and feedback—are highly compressible, while open-domain knowledge depends more on large-scale parameters. VibeThinker-3B demonstrates that small models, when specialized for tasks with clear verification signals, can reach frontier performance, offering a complementary research path to scaling model size. The model is publicly available for download and testing.

Why Is the World Nervous About Japan Raising Interest Rates?

In June 2026, the Bank of Japan raised its policy rate to 1%, marking its first hike to this level since 1995. While this rate remains low compared to global peers like the US and Europe, the move signals a profound shift for a nation that has been a global source of ultra-cheap funding for decades. Japan's long-standing near-zero or negative interest rates had facilitated massive "yen carry trades," where international investors borrowed low-cost yen to invest in higher-yielding assets worldwide, such as US tech stocks and emerging market bonds. This made Japan a critical, often overlooked, source of global liquidity. Japan's ultra-loose policy stemmed from structural challenges post-1990s asset bubble: aging demographics, chronic low inflation/deflation, and high public debt. Recent shifts, including sustained wage growth (exceeding 5% in recent years) and inflation consistently above the 2% target, have created a "wage-price spiral" possibility, prompting the policy normalization. The global market's concern lies not in the absolute rate but in the potential unwinding of the yen carry trade. As Japanese borrowing costs rise, the economics of these leveraged global investments change, potentially triggering deleveraging and capital outflows from risk assets. Market anxiety focuses on the end of a thirty-year consensus that Japan would perpetually provide cheap funding. Ultimately, the global impact will depend on the interplay with US monetary policy. While Japan is tightening, the significant interest rate differential with the US remains. The key future dynamic is whether simultaneous Japanese hikes and eventual US rate cuts will narrow this gap, forcing a major recalibration of global capital flows and asset pricing built on an era of abundant, cheap yen liquidity.

Research Report Analysis: MRVL's Optical AI Booming, Why High Valuation Keeps Morgan Stanley's Star Analyst Sidelined?

Report Recap: MRVL Optical AI Boom - Why High Valuation Led Morgan Stanley's Star Analyst to Stay Neutral? Morgan Stanley analyst Joseph Moore maintained an "Equal-weight" (Neutral) rating on Marvell Technology (MRVL) on May 28, raising the price target from $172 to $195, below the trading price. This stance comes despite Marvell reporting a record quarter and significantly raising its full-year outlook (FY27 revenue ~$11.5B, up ~40%). Moore's neutral view is based on valuation. The $195 target implies ~40x CY2027 P/E. He contrasts MRVL with NVDA: both trade near ~$200, but Nvidia's forward EPS is more than double Marvell's. For MRVL's valuation to hold, it needs consistent earnings upgrades, proof of networking market share gains, or certainty on large-scale custom AI chip shipments—none of which are confirmed yet. Growth is driven by two pillars: **1) Optical Interconnect** (the faster runner): Moore raised FY27 growth expectations to >70%, with the optical module product line nearing a $1B annualized run rate. **2) Custom AI Chips** (the climber): Confidence in FY28 is growing, but a major new customer project only ramps in FY28, with no current revenue visibility. Key risks are the underperforming Storage, Enterprise, and legacy Networking segments. Moore acknowledges the real AI opportunity but believes the current price already reflects it. For the stock to work from here, investors need to see the optical business hit its targets, custom chips ramp as planned, and a recovery in the weaker business units.
