Treasury bonds are down. Momentum is near a 12-month low. So why is money still flowing in?
That's the question our data is flagging in IEF — the iShares 7-10 Year Treasury Bond ETF — right now. Price has pulled back hard, RSI is at its 8th percentile, rate-of-change is at its 2nd percentile. By the composite score, this looks like weakness. But the flow picture tells a different story: CMF at its 90th percentile, OBV slope at its 83rd. Capital is moving into a falling price. That combination has a name in our framework: a Slow Build.
The Conventional Read
The consensus on intermediate Treasuries in early April 2026 is cautious. The "higher for longer" inflation narrative has been disrupted by a genuine stagflationary shock — Brent crude near $120 per barrel following Middle East supply disruptions, yet simultaneous evidence of economic contraction is building. The Federal Reserve is caught: cut rates to support growth and you risk reigniting inflation; hold and you risk breaking the economy.
In this environment, most analysts are underweight duration. The argument goes: real yields are still elevated, the Treasury supply picture is enormous ($40T+ outstanding), and oil-driven CPI makes it politically difficult for the Fed to pivot. Intermediate bond funds like IEF, which hold 7-10 year maturities, sit in an uncomfortable middle ground — long enough to be hurt by any re-rating of inflation expectations, short enough to not benefit fully from a flight-to-safety panic in long-duration.
And yet. The 10-year yield broke below 4% on March 30. IEF closed April 1 at $95.04, up from a low of $94.59 on March 26. Something is buying.
What the Percentile Data Shows
Our framework maps every asset across four independent dimensions — Extension (how stretched is price vs its moving averages?), Momentum (is price gaining or losing energy?), Flow (is capital coming in or going out?), and Volatility (is the market environment calm or turbulent?) — all expressed as percentile ranks against IEF's own trailing 12-month history.
As of April 1, 2026:
| Dimension | Percentile | Plain Reading |
|---|---|---|
| Extension | 11th | Price is more compressed vs its moving averages than 89% of the past year |
| Momentum | 16th | Rate-of-change and RSI are weaker than at 84% of readings |
| Flow | 67th | Money flow indicators are stronger than at 67% of readings |
| Volatility | 58th | Market turbulence is above average but not extreme |
The individual readings underneath are striking. RSI-14 is at its 8th percentile (42.3 raw). ROC-21 is at its 2nd percentile (-2.0%). These are historically depressed momentum readings. But CMF-20 is at its 90th percentile. OBV slope at its 83rd percentile. Force Index at its 30th percentile.
A composite score would call this asset "weak." And it is weak on price and momentum. But that misses the point: two independent flow indicators are telling you that someone is accumulating into that weakness.
The Historical Test
We searched our full IEF history for every date where Extension was below the 25th percentile, Momentum was below the 25th percentile, and Flow was above the 55th percentile — the same dimensional profile as today. We found 30 matching episodes with complete 21-day forward data.
Hit rate at 21 days: 80% positive (24 of 30 episodes) Median return at 21 days: +1.15%
Of the 19 episodes with complete 63-day data: Hit rate at 63 days: 74% positive (14 of 19 episodes) Median return at 63 days: +2.1%
For context, the baseline positive-day rate for IEF over the same period is approximately 52%. This profile lifts that materially. But the range of outcomes is wide — some 63-day returns clustered around -1.4%, others reached +3.8%. Same signal, dramatically different outcomes. That's where the discriminator matters.
The Episode Comparison
Four episodes stand out as the closest analogues to today.
January 2025 (Jan 6–14) — The Strongest Match IEF trading between $91.17 and $92.26, near a 12-month low. Extension at the 5th–20th percentile. Momentum at the 10th–24th. Flow at the 65th–74th. Volatility at the 21st–29th percentile — notably calmer conditions underneath the weakness than today. From January 14 at $91.20, IEF returned +3.8% at 63 days. This was the period where rate-cut expectations began pricing in more aggressively as growth data weakened.
December 2024 (Dec 23–31) — The Patient Resolution IEF between $92.08 and $92.62. Extension at the 5th–23rd, momentum at the 12th–24th. Flow at the 63rd–73rd. The 21-day picture was flat (+0.06% to +0.40%). But at 63 days, returns ran from +2.69% to +3.52%. The setup took time to resolve. Patient holders from that cluster reached the January 2025 resolution.
April 2025 (April 11) — The Moderate Template IEF at $93.51. Extension 24th percentile, momentum 18th, flow 66th, volatility 53rd — the volatility profile most similar to today. Returns: +1.27% at 21 days, +0.83% at 63 days. Positive but not dramatic. This is arguably the better template for the current environment given the elevated volatility context.
March 2026 (Mar 10–11) — The Cautionary Case IEF at $96.00–96.44. Extension at the 6th–16th, momentum at the 10th–20th, flow at the 61st–63rd, volatility at the 37th–41st. Returns at 21 days: -1.0% to -1.04%. The only clearly negative outcome in the recent batch. Flow was elevated but slightly lower than today, and the macro environment lacked the urgency of genuine recession fear that characterises April 2026.
The Discriminator
Looking across all 30 episodes, one pattern separates outcomes: CMF level and the volatility regime together.
In every strongly positive episode, CMF was at or above the 90th percentile — historically extreme buying pressure, not just elevated. In the negative episodes, CMF was elevated but either lower in the range (85th–93rd) or beginning to fade as momentum continued to deteriorate.
Today's CMF is at its 90th percentile. OBV slope at its 83rd. The flow signal is at the edge of the "strongly positive" territory. But the volatility dimension at 58% is meaningfully higher than in the January 2025 setup (21st–29th then). Higher volatility with strong flow historically produces more modest but still positive returns — consistent with the April 2025 template (+1.3% at 21 days).
The discriminating question: does CMF stay above 85th percentile as price stabilises? Historically, when it does, the base rate strongly favours recovery. When CMF fades below 70th while extension stays compressed, the pattern shifts toward the March 2026 cautionary case.
The Fundamental Tension
Both sides of the IEF debate have real data right now.
The bull case: The 10-year yield breaking below 4% on March 30 reflects a fundamental shift in macro consensus. US Treasuries, alongside UK and Japanese bonds, have advanced on the view that surging oil prices from Middle East disruptions may herald a protracted global slowdown — and that the growth risk ultimately outweighs the inflation risk. In this scenario, the Fed eventually prioritises growth over inflation, real yields fall, and 7-10 year duration is the sweet spot: long enough to benefit from a meaningful rate rally, short enough to avoid TLT's extreme sensitivity.
The bear case: Brent crude near $120 is genuinely inflationary. If the Fed holds or hikes to combat oil-driven CPI, intermediate bond prices fall. The fiscal backdrop is also structurally problematic — $40T+ in outstanding Treasury debt with sustained high deficits creates enormous supply that requires global demand absorption. BlackRock entering 2026 noted that global risk assets embraced a Goldilocks mindset, but below the surface macro risk remained a meaningful driver — and positioning can flip quickly on any geopolitical resolution.
The DXY complexity: The US Dollar Index recovered to approximately 100.22 by March 31 from a 2025 low near 96, recovering toward a key resistance level. A strengthening dollar and a Treasury rally can coexist as dual risk-off expressions. But if the dollar strengthens because of relative growth outperformance rather than panic, that's bond-negative — growth optimism reduces the urgency of rate cuts. The next few weeks will clarify which story is driving both moves.
Where We Are Now
Today's IEF profile sits between two historical templates. The January 2025 analogue — the most positive outcome — had more orderly accumulation (lower volatility), suggesting confident, directional buying. The April 2025 analogue — the more modest outcome — had a similar volatility regime to today and delivered positive but contained returns.
The March 2026 cautionary case had one key difference from today: the macro backdrop lacked a clear catalyst for duration demand. The current environment has that catalyst — the 10-year already broke 4%, recession signals are building, and the market appears to be choosing growth fear over inflation fear.
The honest assessment: this is a setup where the data leans positive (80% hit rate at 21 days, 74% at 63 days), the flow signal is at a historically meaningful level, and there is a credible macro thesis underneath it. But the elevated volatility and the unresolved DXY question widen the error bars relative to the cleanest historical setups.
What to Watch
1. CMF trajectory over the next 5–10 sessions. If CMF stays above the 85th percentile as IEF price stabilises, that matches the pattern preceding the January 2025 and December 2024 recoveries. If CMF fades below 70th percentile while price stays compressed, re-evaluate — the flow thesis is degrading.
2. The $95.50–$96.10 level (50-day SMA region). IEF at $95.04 on April 1 is below its 50-day moving average (approximately -1.1%). A reclaim of the 50-day on sustained volume signals a shift in the extension picture and would likely correspond to the 10-year yield holding below 4%. A break below $94.59 invalidates the Slow Build thesis and starts looking like distribution.
3. DXY at the 100 level. Watch whether IEF and DXY move together (both risk-off) or diverge (dollar strength from growth optimism, which is bond-negative). The nature of that correlation in the next 2–3 weeks clarifies the macro scenario driving both.
