BTC Up, Fed Rate Hike, & AMD $1T

View from the Arch #150

This was the week we’ve all been waiting for!

This Week at Arch: Put a tax bill to work

TaxShield is built for business owners facing a large tax bill and looking for a productive use for the money behind it.

The structure pairs a Bitcoin-backed loan from Arch with hosted mining equipment from Blockware. Blockware handles deployment, hosting, power, and monitoring. If the equipment qualifies, bonus depreciation under Section 168(k) may help offset taxable income, while the miners produce Bitcoin each month.

Your depreciation target, the equipment purchase, and the loan amount are configured together, so the funding is sized to the invoice instead of leaving you to coordinate the numbers yourself.

The result is a strategy designed to turn a tax expense into an income-producing Bitcoin asset, while you continue to hold your original Bitcoin exposure.

Tax treatment and eligibility depend on your situation. Review the structure with your tax professional.

This Week in Crypto

Bitcoin finally had a week that made the last few months of sideways grinding feel worth it.

  • After the Fed’s rate hike briefly knocked BTC down to $75,900 on September 16, BTC totally took off, tearing through $80K within two days and then blowing past that entirely.

  • It hit $85,000-$86,000 by Monday for a nine-month high, a roughly 13% run off the week’s low.

  • ETF flows flipped from outflows to a 2026-record $999M single-day haul on Monday.

The CLARITY Act flatlined on a Senate cloture vote, 49-50, killed by the same ethics fight that’s dogged it for months.

  • Congress pivoted to a smaller, less controversial target: on September 16, the House Financial Services Committee advanced the American Reserve Modernization Act, which would codify the existing Strategic Bitcoin Reserve, with a 20-year no-sell holding period on the roughly 324,500 BTC ($24.7B) the government already holds.

This Week in TradFi

The Fed finally pulled the trigger on its first rate hike since 2023 - a quarter point, taking the target range to 3.75%-4% by a unanimous 12-0 vote.

  • Stocks sold off on the day, then spent the rest of the week coming back up.

  • The Dow limped through its third straight losing week (down 1.7%, worst since March) while the Nasdaq eked out a gain. And by Monday tech had fully reclaimed the narrative - the S&P 500 climbed 1.5%, and the Nasdaq hit a record close above 27,100.

In today’s episode of Succession, Warren Buffett, 96, stepped down as Berkshire Hathaway's chairman after 56 years in the role, becoming chairman emeritus while his son Howard takes the gavel.

  • Since he took over in the 1960s, Berkshire's shares are up more than 5,500,000% against the S&P 500's roughly 39,000% over the same stretch.

The Washington summit between Trump and Xi kicks off today, the first Chinese state visit to the U.S. since 2015.

  • Trade, rare earths, AI, and Taiwan are all on the docket, but expectations are deliberately modest.

  • Most China-watchers expect an extension of the Busan trade truce rather than any real breakthrough, with agricultural and Boeing purchases as the likeliest concrete deliverables.

This Week in Tech

AMD closed above $1T in market cap for the first time Monday, jumping about 9.6% to a record $613.31 a share.

  • The stock is up roughly 185% for the year.

  • The milestone puts AMD in the same league as Nvidia, Broadcom, and Micron.

SoftBank launched an $11B-equivalent bond sale Monday to fund the third of three $10B tranches in its OpenAI investment.

  • If it prices at size, it'll be the largest non-financial corporate bond deal ever out of Asia-Pacific.

  • The total SoftBank commitment to OpenAI is roughly $65B.
