This spring, a client had been house-hunting on Seattle's Eastside for three months. He finally found the right home, agreed on price, got pre-approved at 5.9% — everything was set.
Then on February 28th, the Middle East went to war.
Two weeks later, his rate was 6.4%. Same house, same loan amount — $320 more per month.
He asked me: what does a war in the Middle East have to do with my mortgage payment in Seattle?
Today I'll explain how a single geopolitical conflict works through two completely different pathways to simultaneously suppress your home-buying opportunity. Path One hits demand: rates rise, payments get more expensive, fewer people can buy. Path Two hits supply: oil prices rise, construction costs go up, new home supply contracts.
Chapter 1: How Did Your Payment Go Up?
Many people think the Fed sets mortgage rates. This is wrong. The Fed controls the federal funds rate — short-term interbank lending. Your 30-year fixed mortgage tracks the 10-year Treasury yield. These two can move in completely opposite directions.
In September 2024, the Fed cut rates 100 basis points. During that period, the 30-year fixed actually rose from 6.1% to 7.1%. Why? Markets didn't believe inflation was controlled; long-term rates rose on their own.
After the February 28 US-Israel strike on Iran: oil prices surged 11% in 72 hours, exceeding $95/barrel. Inflation expectations jumped. Fed cut probability fell from 68% to 31%. The 10-year Treasury rose from 4.2% to 4.7%. Banks add 120-150 basis points on top: 5.9% became 6.4%. On an $800K loan, that's $320/month more — $3,840/year extra.
Chapter 2: How Did Construction Costs Rise?
PVC pipes, waterproofing, insulation, asphalt roofing — all petroleum-derived. Oil up 10%, these materials follow. Add 2026 tariffs: 25% on imported steel, 14.5% on imported lumber.
Hard costs (labor + materials + construction) are 50-60% of total project cost. This combination added $18,000-$22,000 per new home. Many projects stalled. Washington State already has a 370,000-unit housing deficit, adding 80,000 people per year, while new starts continue declining.
Result: demand shrinking and supply shrinking simultaneously — prices have nowhere to go.
Chapter 3: Why Different Markets React Differently
You might ask: I see news of Texas and Florida prices falling — why not Seattle? This is the concept of inventory bifurcation. After COVID, America split into three distinct housing markets: the Northeast and West Coast (including Seattle) where inventory remains tight; the South (Texas, Florida, Arizona) where overbuilding left excess inventory; and the Midwest in between.
Same war, same rate shock — completely different outcomes.
Chapter 4: The Most Dangerous Misconception
Seattle is experiencing some price reductions — but understand which segment: the $1.5M-$2.5M Eastside tier (Bellevue core, Kirkland, Redmond top school districts) is seeing days-on-market stretch and active price cuts, because this segment's buyers are primarily Chinese-American tech workers facing three simultaneous pressures: AI layoff anxiety, immigration policy uncertainty, and higher rates eating into affordability.
But the $800K-$1.2M range (Shoreline, Everett) tells a completely different story — broader buyer pool, thinner existing inventory, far less price pressure.
'Seattle is discounting' is only half right. The accurate description: high-price segment under pressure, lower-price segment holding. It's bifurcation, not a general market decline.
Chapter 5: Three Things Not To Do
Don't wait for a Fed rate cut — the Fed cuts short-term, your mortgage tracks long-term Treasuries. Don't apply Southern market logic to Seattle — Texas and Florida's situation reflects excess inventory, not Seattle's reality. Don't ignore employment confidence — many Seattle tech buyers have the money and the credit but won't commit. Fear of AI layoffs, income stagnation, and the next wave of cuts is more persistent than any oil price shock, and it's the real suppressor of transaction volume.
