Your mortgage rate just got a new ceiling: 5.15%

The 10-Year Hit 5.15%. Your Mortgage Felt It.
The benchmark Treasury yield climbed 6 basis points Monday to 5.15%, as money rotated out of bonds and back into tech. It's a small daily move with a large ongoing consequence: 30-year fixed mortgage rates are already running well above 7%, and yields at this level keep them there.
30-year Treasury yield held ~5.43%, widening the 5-to-30-year spread to 54 basis points — bond markets are pricing in elevated rates for a long time, not just a bad quarter.
Junk bond yields hit an 18-month peak last week, with CCC-rated spreads at a four-year high: smaller, indebted companies are paying sharply more to borrow, and some won't be able to.
The Fed enters its pre-meeting blackout today, ahead of the 28 October decision where Chair Kevin Warsh is widely expected to hold at 3.75–4.00%. Nobody's riding to the rescue before then.
💬 A 10-year yield above 5% is the invisible hand squeezing your mortgage, your car loan, and every overleveraged company's credit line simultaneously. The Fed's silence this week makes it louder.

Brent Just Crossed $110. No Ceasefire in Sight.
Attacks on tankers and Saudi energy infrastructure over the weekend pushed Brent crude above $110 a barrel in Asian trading this morning, its highest print since May. No diplomatic breakthrough emerged overnight. The geopolitical premium isn't going anywhere yet.
Every $10 rise in Brent adds roughly $0.24 to a gallon of petrol — that math hits forecourts within days, then ripples into anything transported by road or air.
Oil is up approximately 8% over the past week, and the ECB specifically cited Middle East conflict when it last raised rates. The 29 October ECB meeting now looks more complicated.
The Brent-WTI spread widened to ~$11, reflecting supply-route risk specific to the Middle East rather than a broad demand surge. US drivers get some insulation. Not a lot.

South Korea Is Down 21% From Its Peak and Still Falling
The KOSPI dropped another 2% in early Tuesday trade, with SK Hynix off 4% and Samsung down nearly 2%. That's on top of a 14.5% weekly loss last week, including a single-day crash that triggered the exchange circuit-breaker. The index is firmly in bear territory.
~$200 billion in market value erased over the past week alone, the steepest fall since the COVID collapse of 2020.
The proximate cause: investor doubt about AI capital expenditure sustainability, accelerated by Chinese memory chipmaker CXMT disclosing a more efficient memory cell design last week.
SK Hynix and Samsung supply the majority of the world's high-bandwidth memory for AI accelerators. When their shares fall like this, it's the market questioning whether the AI buildout is as durable as the last two years suggested.
💬 The KOSPI is essentially a live ticker on global confidence in the AI trade. Right now it's flashing amber — almost red.

China Q3 GDP grew 4.5% year-on-year, beating the 4.4% consensus and pushing the PBOC's yuan fix to its strongest level since February 2023 (USD/CNY 6.7298); the beat reduces the probability of near-term PBOC rate cuts and lifted the Australian dollar, which tracks Chinese demand.
NAB announced it will cut 2,500 jobs (6% of its workforce) by mid-2027, booking an A$300 million pre-tax restructuring charge; shares fell 2.90% against the ASX 200's 0.30% decline, and full-year results on 5 November will show investors how deep the damage goes.
China's PBOC held its one-year Loan Prime Rate at 3.00% and five-year LPR at 3.50% for the 17th consecutive month, and separately announced daily overnight reverse repo operations from 21 October — a potential signal of the most significant overhaul to Chinese monetary transmission since 2015.
