The Treasury said it would step up purchases of its own long-dated debt, and the 30-year yield fell 9 basis points to 5.19%. The 20-year auction then stopped below the line this letter set for returning demand, and an hour later the Fed minutes showed more officials than the three dissenters wanted a rate increase. The S&P 500 rose 0.21%, ending three days of declines. Bitcoin rose 7.61% to its highest close since 1 June. Health care gained 3.51% to a 2026 high. Seoul closed 5.80% lower before the announcement.

§ 03 — Equities · Global

All figures reference Wednesday 19 August closes from FMP end-of-day data. One-week moves compare with Wednesday 12 August, and year-to-date with each market’s last 2025 close. Asian sessions ended hours before the US Treasury’s buyback announcement; Europe’s session overlapped it. Thursday’s live Asian session is not included in this table.

Asia’s Wednesday sessions closed hours before the Treasury announcement. The KOSPI fell 5.80% to 6,471.17, the table’s largest fall, finishing below the 6,813.34 level watched here since 13 August. Samsung fell 7.82% and SK hynix 9.75%. The Nikkei lost 3.16%, Shanghai 2.40% and the TAIEX 1.30%. Europe, open through the announcement, closed nearly flat. In live Thursday trade the KOSPI was about 3.6% higher, the first Seoul session priced with the news. Seoul also lost the table’s 2026 lead: Taipei now leads at 54.40% against 53.56%.

§ 04 — US Treasuries

3.5% 4.0% 4.5% 5.0% 6M 2Y 5Y 10Y 20Y 30Y

The longest maturities fell most while bills and the 2-year note barely moved. The 10-year fell 6 basis points to 4.65%, the 20-year 11 to 5.17% and the 30-year 9 to 5.19%. That is 12 basis points below Monday’s close, which was the highest since June 2007. The Treasury’s plan buys long-dated debt, and the fall sat in exactly those maturities. The 20-year auction stopped at 5.204%, above July’s 5.163% and below the 5.23% line set here for demand returning. The plan was public before the auction, so demand was helped. The gap between 2-year and 30-year yields narrowed to 100 basis points from 109. Bills still pay less than the 2-year note, so the priced path remains fewer increases, not cuts.

§ 05 — Credit Spreads

Credit’s latest reading predates the announcement. The observations run through Tuesday, one session behind. High yield widened 5 basis points to 275, the weakest borrowers 9 to 1,027, investment grade 1 to 82 and BBB 1 to 100. A modest response to a falling equity day. Wednesday’s reading will show whether the buyback news pulled spreads back in. The 5-year yield, nearest to what borrowers pay, sits 3 basis points below a week ago.

Credit spreads are FRED ICE BofA option-adjusted spreads (IG BAMLC0A0CM, BBB BAMLC0A4CBBB, HY BAMLH0A0HYM2, CCC & Lower BAMLH0A3HYC) as of the Tuesday 18 August close, the latest observation FRED has published, so this table runs one session behind the rest of this letter and predates the Treasury announcement. One-day changes reference the Monday 17 August close, one-week changes the Tuesday 11 August close, and year-to-date the last 2025 observation. Widening (positive basis points) reads as stress. Narrowing reads as relief.

§ 06 — Digital Assets

Bitcoin rose 7.61% to US$69,603.52, its largest daily rise since 6 February and its highest close since 1 June. Ether rose 18.10% to US$2,263.57, its largest daily rise of 2026. Solana gained 11.13%. Three things helped on the same day. The buyback news pulled long yields down. The SEC proposed its first dedicated token rules. And the president, hosting industry executives, said a government bitcoin purchase has been discussed. The August band of US$63,000 to US$65,000 broke upward. Two closes above US$69,000 confirm the break, and a close back inside the band voids it. Bitcoin remains down 20.45% for 2026.

Bitcoin’s equity link reflects the historical daily-return pattern, closest to the Nasdaq at about 0.5 and loosest to the Dow at about 0.4. Levels are FMP end-of-day closes for the UTC day ended Wednesday 19 August. Daily moves compare with Tuesday, weekly with Wednesday 12 August, year-to-date with the 31 December 2025 close.

§ 07 — Metals & Energy

Gold rose 2.82% to US$4,545.30 on a day the 2-year yield did not move. With its usual short-rate driver absent, the better fit is the dollar, which fell after the buyback news. The euro rose 0.79%. Silver rose 2.79%. Brent added 0.66% to US$91.62, a third consecutive close above US$90 and its highest since 24 July, after the United Arab Emirates halted trade with Iran. WTI fell 0.65% the same day, as US crude stocks rose by 4.4 million barrels against an expected draw. US supply loosened while the Iran risk stays priced in Brent. Natural gas rose 1.37%.

§ 08 — Economic Calendar

US release times are Eastern. China’s loan prime rate fix is shown in Beijing timing. Japan’s July inflation prints Friday 08:30 Tokyo time. Earnings timing and EPS consensus are from the FMP earnings calendar (Walmart and Deere before Thursday’s open, Nvidia after Wednesday’s close). PMI consensus shows manufacturing / services. Consensus and priors are FMP-sourced.

Walmart reports Thursday morning and Nvidia next Wednesday evening, the calendar’s two largest results. Deere also reports Thursday. Jobless claims are expected at 210,000 and the Philadelphia Fed index at 25.0, down from 41.4. Japan’s July core inflation is expected to rise to 1.8% Friday morning Tokyo time. UK retail sales and the August PMI round follow Friday. Nvidia’s consensus is US$2.09 per share on revenue of about US$92 billion.

§ 09 — Macro Themes

1 · The two arms of US policy pointed in opposite directions. The Treasury moved to lower long yields by buying its own debt. An hour after the auction, the minutes leaned toward higher rates. Long yields fell and the 2-year held, matching the first and ignoring the second.

2 · The strongest responses came from the assets that had fallen furthest. Ether, down 35% for the year as of Tuesday, rose 18.10%. Solana, down 38%, rose 11.13%. Bitcoin, down 26%, rose 7.61%. The S&P 500, 1.37% below its record as of Tuesday, rose 0.21%. No earnings news drove any of the three.

3 · Health care’s gain came from a drug trial, not from the macro story. Moderna’s and Merck’s mRNA cancer-vaccine results sent the sector up 3.51% to a 2026 high. Health care now sits fifth for the year at 13.49%, up from seventh on Tuesday. The 2026 leadership now extends past energy and technology.

4 · Korea took its worst day of the episode before the announcement. The KOSPI’s 5.80% fall ended at 02:30 New York time, before the buyback news. Thursday’s session, up about 3.6% at publication, is the first Seoul trade priced with it. The floor is broken. Friday decides whether that stands.

§ 10 — Analysis & Nuances

A fall in long yields that comes from an announcement is different from one that comes from data. Three facts tie Wednesday’s to the announcement. The fall sat in the longest maturities, the 20-year down 11 basis points with the 2-year unchanged. TLT, the largest long-bond fund, opened 1.41% above Tuesday’s close, so most of the move preceded regular trading. And the auction cleared at 5.204% only after the buyback plan was public. The short-rate outlook did not change. The minutes leaned toward higher rates, and bills still pay less than the 2-year note. The assets that jumped most, bitcoin and gold, have no cash flows to anchor them, and both were helped by the dollar’s fall after the buyback news. Equities, which also answer to the Fed, rose 0.21% and faded from the morning high. The 2-year is the reading to watch: it already prices the Fed’s position, so neither the minutes nor a strong retailer moved it. Walmart tests it today.

Scorecard. The 20-year auction test resolved at 5.204%, below the 5.23% demand-returning line, with the caveat that the buyback news helped it. The KOSPI closed 5.02% below its 6,813.34 floor, and Friday decides. The 2-year sits at 4.19%, nine basis points above the 4.10 line watched here, unmoved by Target’s results. Brent logged a third close above US$90. New test: a 30-year close above 5.28% this week reads as the buyback effect fading, and a hold below 5.20 through Friday reads as it sticking.
