The Economic Snapshot

Where the Economy Stands Today

The effective Fed Funds rate sits at 3.63%, more than 75% above its long‑run average of 2.06% and in the 69th percentile, indicating a persistently tight monetary stance that compresses credit spreads and raises funding costs for banks.
Long‑term yields are elevated (10‑yr Treasury 4.47% vs 2.71% avg, 95th percentile) while the 2‑yr is climbing to 4.05% (80th percentile), creating a steep yield curve that typically benefits net interest margin expansion for lenders with a duration mismatch.
Inflation remains above target with headline CPI at 3.9% YoY (78th percentile) and core CPI still rising at 3.0% despite being near its historical mean, suggesting price pressures are sticky enough to keep real rates positive.
Real GDP growth has slipped to 1.6%, well below the 2.64% average and in the bottom quintile, signaling a slowdown that could dampen loan demand but also limit credit losses as borrowers remain employed.
Unemployment is stable at 4.3% (near its long‑run median) while consumer sentiment has plunged to 49.8 – the lowest on record – indicating weak household confidence that may suppress discretionary borrowing and deposit growth.

Highlight

The combination of a steepening yield curve and elevated short‑term rates creates a favorable net interest margin tailwind for Coastal Financial, as each 100 bp rise in the Fed Funds rate historically adds roughly 0.12 pp to NIM for regional banks; with rates currently 1.6 percentage points above average, CCB could capture an incremental 0.19‑0.20 pp of margin if it maintains its asset‑liability mix.

Key Indicators Summary

Economic & Company Trends

CCB — Company Snapshot

Key Fundamentals at a Glance

Revenue growth has surged to +54.3% YoY – the fastest pace in the past five years – reflecting aggressive loan book expansion and higher yield on new assets as rates remain high.
Operating margin is contracting (8.2% vs 9.5% historical median) as expense growth outpaces revenue, mainly from rising personnel costs and technology investments needed to support loan origination at a time of tighter credit standards.
Free cash flow growth has slowed to +7.6%, indicating that while earnings are expanding, capital expenditures on branch upgrades and digital platforms are absorbing much of the cash generation.
Return on equity remains low at 2.4% and unchanged year‑over‑year, underscoring the challenge of translating higher interest income into shareholder returns given thin margins and a modest asset base (ROA 0.2%).
The stock’s 12‑month return of +37% outperforms the S&P Regional Banks index (+21%) but is driven largely by market pricing of rate sensitivity rather than intrinsic profitability improvements.

Watch Out

If the Fed were to cut rates by 50 bp within the next six months – a scenario implied by some market forecasts – CCB’s net interest margin could fall by ~0.06 pp (based on its historical NIM elasticity of -0.12 per 100 bp), eroding earnings enough to reduce EPS by roughly $0.05 and potentially trigger a 5‑7% pullback in the stock price.

Macro Sensitivity Coefficients

Bar values = average of level and change coefficients across all targets for each macro variable.

Exposure Classification

Company Traits

Revenue growth rises when the CPI level is higher (β_level=+0.1271) and accelerates further as CPI changes upward (β_change=+0.3198), reflecting CCB’s ability to pass modest price increases onto borrowers despite low pricing power (53/100). Rate levels have a modest positive effect (β_level=+0.1047) but a strong boost when rates are rising (β_change=+0.7060), indicating that higher short‑term funding costs are offset by increased loan demand in a tightening environment, consistent with its medium duration and low leverage (25/100). Mortgage market conditions also lift growth both at high levels (β_level=+0.2266) and when mortgage rates climb (β_change=+0.3147), underscoring CCB’s exposure to the housing finance cycle. Conversely, consumer sentiment is a drag: higher consumer index levels depress revenue (β_level=-0.3538) while rising consumer activity still adds a modest lift (β_change=+0.2190), highlighting that CCB benefits more from improvements than from absolute high consumer spending, which aligns with its high cyclicality (100/100). Unemployment shows the expected negative relationship at both level and change (β_level=-0.2621, β_change=-0.0674), confirming that job losses directly curtail loan demand.

Key Macro Exposures

CPI exposure: β_level=+0.1271, β_change=+0.3198; 80% level stability, 100% change stability – modest inflation pass‑through despite low pricing power.
Rate exposure: β_level=+0.1047, β_change=+0.7060; 60% level stability, 100% change stability – strong upside when rates rise because loan demand spikes in a tightening cycle.
Mortgage exposure: β_level=+0.2266, β_change=+0.3147; 60% level stability, 80% change stability – growth tied to housing finance activity.
Consumer exposure: β_level=-0.3538, β_change=+0.2190; 100% level stability, 80% change stability – high‑level consumer strength suppresses growth, but improvements still provide a lift.

Macro Sensitivity & Exposure

CCB — Implications

Scenario Analysis

In a rising‑rate, moderate‑inflation environment, CCB’s revenue growth is likely to accelerate (combined β_change ≈ +1.04 from rates and CPI). Conversely, a downturn in consumer confidence or a spike in unemployment would erode growth sharply, as the negative βs for consumer level (-0.35) and unemployment (-0.26) dominate.

Macro Risks

Consumer contraction risk: β_level=-0.3538 means a 10‑point drop in the consumer index could cut revenue growth by ~3.5 pp, a material hit given CCB’s high cyclicality.

Macro Opportunities

Rate‑rise tailwind: β_change=+0.7060 implies that each 100 bp increase in rates could boost quarterly revenue growth by roughly 7 pp, offsetting other headwinds and supporting earnings upside.

Data-Derived Risks & Tailwinds

INVESTOR TAKEAWAY

Investors should view CCB as a bet on an environment of rising rates and stable inflation, which historically fuels its loan demand. However, they must monitor consumer sentiment closely—any weakening could quickly offset the rate tailwind. Positioning with a modest overweight in CCB is appropriate when forecasts show continued rate hikes and resilient consumer spending, but reduce exposure if consumer confidence shows signs of deterioration.

Macro Event Response

CCB — Event Day Reactions

This event‑response analysis quantifies how Coastal Financial Corporation (CCB) price reacts to macro‑economic releases, earnings announcements, and regulatory news over the past five years. Understanding these sensitivities is critical because CCB’s balance sheet and net interest margin are tightly linked to policy shifts, while earnings surprises drive investor sentiment. The study isolates event windows to gauge immediate abnormal returns and compares them against the S&P 500 benchmark.

Methodology: Event Study with Bootstrap Inference

Company-Specific Event Responses

Federal Reserve rate decisions generate the largest single‑day moves: a +25 bp surprise yields an average +1.2% abnormal return for CCB versus +0.5% for the S&P 500, reflecting its high net‑interest‑margin exposure (rate sensitivity ≈ +0.48).
Quarterly earnings beats (>100 bps EPS beat) produce a +2.4% one‑day jump, outpacing the market’s +1.1% reaction, driven by upgraded loan‑loss provisions and higher fee income guidance.
Regulatory capital announcements (e.g., OCC stress‑test results) cause a -1.8% dip when CCB is flagged for elevated risk‑weighted assets, double the sector average of -0.9%.
Housing‑market data releases (existing‑home sales) have a muted effect: CCB’s abnormal return averages +0.2%, statistically indistinguishable from the index, indicating limited direct exposure to residential loan volume.
Geopolitical risk spikes (e.g., sudden oil price shocks) produce negligible moves (<0.1%) for CCB, underscoring its focus on domestic commercial banking rather than commodity‑linked assets.

Highlight

The most actionable pattern is the asymmetric response to Fed rate surprises; a 50 bp tightening shock historically depresses CCB by -2.4% versus -1.0% for the S&P 500, suggesting that positioning long CCB ahead of expected easing cycles can capture outsized upside.

Macro Event Response

CCB — Post-Event Follow-Up

Post-Event Follow-Up (6-Month Returns)

Compares event-day reaction to 6-month subsequent return. Momentum: same direction as event-day. Reversal: opposite direction.

Rate‑surprise gains tend to persist: on average, CCB retains 65% of its one‑day abnormal return after three months, compared with 45% for the broader market, reflecting sustained NIM improvement.
Earnings‑beat excesses reverse partially; only 38% of the initial +2.4% jump remains after six months as analysts normalize forward guidance, indicating a short‑term pricing inefficiency.
Regulatory‑driven declines exhibit limited rebound: 80% of the -1.8% shock persists at the six‑month mark, highlighting lasting credit‑risk concerns among investors.
Macro‑neutral events (housing data) show zero persistence, confirming that their day‑trade impact is noise rather than a trend driver.
Cross‑asset contagion effects are weak; CCB’s post‑event drift does not correlate significantly with broader banking sector momentum, reinforcing its idiosyncratic risk profile.

Watch Out

A rapid succession of adverse Fed surprises (e.g., three 25 bp hikes within six weeks) could erode up to 4.5% of CCB's market cap over a quarter, as cumulative NIM compression compounds with heightened loan‑loss expectations; investors should monitor the forward curve for clustered tightening signals.

This mix places the market in the Mid Expansion phase of the business cycle, a period that historically has been the most supportive for Coastal.

Regime Classification Methodology

Regime & Cycle Analysis

CCB — Regime Performance

Coastal Financial thrives in Stable‑rate, low‑inflation expansions but stalls when policy tightens.

When rates are Stable, CCB has delivered an average monthly return of 4.77%, outpacing its peers and generating a 58.97% positive streak over 39 months. In contrast, tightening cycles have slashed performance to just 0.29% per month (39.3% positive over 28 months), while easing periods only modestly improve returns to 0.49% per month (53.6% positive). The spread between Stable and Tightening regimes—4.48 percentage points per month—highlights a pronounced rate sensitivity rooted in the bank’s net‑interest margin dynamics.

Business Cycle Performance

Mid Expansion quarters have produced the strongest quarterly returns for CCB at 12.87% per quarter over 15 observed periods, dwarfing its performance in Late Expansion (2.20%) and Contraction (-0.59%). Being in Mid Expansion now aligns with the bank’s historical sweet spot, suggesting upside potential if economic momentum sustains.

Regime & Cycle Analysis

CCB — Regime Charts & Implications

Performance by Macro Regime

The current Stable‑rate, Elevated‑inflation backdrop is moderately favorable; while rate stability supports net interest income, the lingering price pressures temper loan growth, keeping performance closer to its mid‑range historical average.

FORWARD LOOKING

If inflation eases below 2% and the Fed pivots to a sustained easing cycle, CCB could capture higher net‑interest spreads, potentially boosting monthly returns toward 5–6%. Conversely, a renewed tightening episode—especially if paired with deeper GDP slowdown—could compress margins and push monthly performance back toward the sub‑0.3% range observed in past tightening regimes.

INVESTOR TAKEAWAY

Investors should overweight CCB while the rate environment remains stable and the economy stays in Mid Expansion, but remain vigilant for any policy shift toward tightening, which would materially downgrade its return profile. A tactical position that can be reduced quickly on signs of a rate‑hike cycle will balance upside from current tailwinds against downside risk from margin compression.

Cross-Sectional & Peer Comparison

CCB — Macro Sensitivity vs Peers

Peer comparison isolates how a firm’s fundamentals react to macro forces relative to its competitive set, revealing unique risk‑return characteristics that absolute sensitivities cannot capture. By benchmarking Coastal Financial Corp (CCB) against similar financial services firms we can gauge whether its earnings and cash flow are more or less exposed to rate, inflation, and growth dynamics than the industry norm.

CCB rate sensitivity of +0.10 vs peer average of +0.32 makes it notably less rate‑exposed than typical financial services peers.

While CCB’s inflation coefficient (+0.13) is modestly above the peer mean (+0.07), its GDP sensitivity (+0.02) aligns closely with the industry baseline (≈0.00). The firm’s beta (0.76) exceeds the sector average (0.62), indicating higher equity volatility, yet its leverage ratio (0.10) is far lower than peers such as BLX (2.55) and CLBK (1.06).

CCB’s business model emphasizes low‑margin deposit taking and conservative loan underwriting, which dampens the impact of rate changes on net interest income but still benefits modestly from higher rates via asset yields. Its relatively tight balance sheet keeps leverage low, limiting sensitivity to macro‑driven de‑leveraging pressures.

Cross-Sectional & Peer Comparison

CCB — Positioning vs Peers

INVESTMENT IMPLICATION

In a rising‑rate environment CCB will likely underperform peers that capture more net interest margin upside, but its low leverage and moderate inflation exposure provide downside protection if rates stall or decline. Investors seeking a defensive financial stock with limited rate volatility may find CCB attractive.

Overall, CCB is less rate‑sensitive, modestly inflation‑positive, and broadly aligned with peers on growth sensitivity, while maintaining lower leverage and higher equity beta. This profile positions the firm as a defensive outlier within a sector that typically benefits strongly from rate hikes.

Sensitivity values are derived from ridge regressions of historical company fundamentals against macro variables.

Macro & Fundamental Time Patterns

CCB — Lead-Lag Analysis

Understanding the lag structure between macro variables and a bank's fundamentals reveals how quickly policy shifts translate into earnings. Timing informs trade execution—whether investors can anticipate moves or must react to realized impacts. For Coastal Financial Corp (CCB), these lags define the horizon for rate, inflation, and growth exposures.

Coastal Financial’s earnings respond to rates in 1Q, CPI in 2Q, and GDP/unemployment in 3Q, with a strong contemporaneous rate correlation (r=0.759).

The strongest link is to the Fed Funds rate, where a 100 bp move translates into a measurable earnings shift within one quarter (r=0.759), indicating high rate sensitivity. Inflation impacts surface after two quarters (r=0.883), suggesting loan pricing and provision cycles lag price pressures. Real‑economy drivers—GDP and unemployment—materialize only after three quarters, with modest correlations (r=0.588 and -0.353 respectively), reflecting the bank’s reliance on credit quality trends that evolve slower than policy.

As a regional lender, CCB’s balance sheet is dominated by loan pricing tied to short‑term rates, so rate changes feed quickly into net interest income. However, provisioning for credit losses and deposit mix adjustments depend on broader economic conditions, which take longer to affect borrower behavior and hence appear with 3‑quarter lags.

TIMING IMPLICATION

Investors can front‑load exposure ahead of anticipated Fed moves—taking positions now to capture the 1‑quarter earnings reaction—while using a 2‑quarter horizon to adjust for inflation‑driven cost pressures. A longer 3‑quarter view is needed to gauge credit‑risk implications from GDP and labor market shifts.

CYCLE POSITIONING

With a mid‑cycle lag profile, CCB sits in the sweet spot where it benefits from near‑term rate moves but remains vulnerable to slower‑emerging growth headwinds, making timing both an opportunity and a risk management focus.

Scenario Analysis & Stress Testing

CCB — Stress Test Results

We evaluate Coastal Financial Corporation (CCB) under four macroeconomic stress scenarios—Mild Stress, Severe Stress (2008‑like), Rate Shock (2022‑like) and a Baseline of unchanged conditions. Each scenario applies historical‑calibrated shifts in Fed Funds rates, CPI inflation, GDP growth and unemployment, multiplied by CCB's empirically derived sensitivity coefficients to estimate revenue‑growth impact.

Revenue growth swings from a -2.32 pp hit under severe 2008‑like stress to a +2.02 pp boost in the 2022 rate‑shock scenario, yielding an overall impact range of 4.34 pp.

Scenario Breakdown

Impact Decomposition (Worst Scenario)

Baseline assumes no macro shift and yields zero impact. Mild stress produces a modest +0.96 pp uplift, driven mainly by higher rates (+0.71 pp) and inflation (+0.32 pp). Severe stress reverses the sign, delivering -2.32 pp as falling rates (-1.41 pp), deflation (-0.64 pp) and a sharp rise in unemployment (-0.27 pp) dominate. The rate‑shock case flips the direction, adding +2.02 pp thanks to a 2‑pp rate hike (+1.41 pp) and inflation surge (+0.64 pp), partially offset by higher unemployment (-0.03 pp).

Key Vulnerabilities

Downside risk is concentrated in the interest‑rate coefficient (0.706) which turns negative when rates fall, and the unemployment coefficient (-0.067) that amplifies losses as joblessness rises; together they account for roughly 80% of the -2.32 pp severe‑stress impact.

CCB shows moderate resilience: its revenue benefits from rate hikes and inflationary environments, but exposure to falling rates and labor‑market deterioration creates a non‑trivial tail risk, especially given the reliability rating of only moderate for these sensitivities.

Key Takeaways

Investors should monitor Fed policy direction; a rapid pivot to rate cuts would erode CCB's revenue growth by over 2 pp, mirroring the severe‑stress outcome.
Inflation trends and unemployment dynamics are secondary but material drivers—each 1 pp rise in CPI adds ~0.32 pp to growth, while each 1 pp increase in unemployment subtracts ~0.07 pp.
Given the moderate reliability of the coefficients, scenario outcomes should be treated as directional guides; however, the asymmetric response to rate moves makes the 2022‑type tightening a clear upside catalyst.

Scenario Analysis & Stress Testing

CCB — Methodology & Reference

Scenario Definitions

Summary & Investment Implications

Key Takeaways

Coastal Financial Corp (CCB) sits in a neutral macro fit with moderate sensitivity to consumer dynamics and a modest stress resilience profile. The current environment—stable rates, elevated inflation around 3.68% and Fed Funds at 3.63%—offers limited upside but also contains downside risks if consumer spending weakens.

CCB

CCB's moderate macro sensitivity combined with a neutral regime fit suggests its earnings are neither strongly buoyed nor severely threatened by the present rate‑stable, inflation‑elevated backdrop. Stress tests show a worst‑case 2.32 percentage‑point revenue hit under a 2008‑type shock, while a 2022‑like rate spike could lift performance by about 2.02pp, indicating balanced resilience.

Investment Implications

Maintain a modest long position (e.g., 5‑7% of portfolio) as the neutral regime implies limited upside but the company’s exposure to rising consumer activity (+0.18 revenue elasticity) offers incremental tailwinds if CPI eases below 3%.
Consider adding a small protective put or overlay at strike levels reflecting a 2.5pp revenue decline, mirroring the -2.32pp stress impact from a severe downturn, to hedge against a sudden consumer pullback.

Trading Considerations

Watch weekly CPI releases; a drop below 3.4% could trigger a short‑term rally as inflation expectations ease and consumer spending picks up.
Monitor Fed’s Beige Book for early signs of consumer sentiment deterioration—if the narrative shifts to ‘declining demand,’ anticipate increased volatility in CCB’s stock.

Risk Watchlist

Consumer falling risk: A sustained month‑over‑month decline in retail sales >0.5% could activate the -2.32pp stress scenario, prompting a reassessment of the position.
Rate shock upside: An unexpected Fed Funds hike above 4.0% would test the +2.02pp upside scenario; if realized, it may warrant scaling back defensive overlays.

Key Takeaways

CCB is positioned neutrally in today’s macro climate—neither a clear winner nor loser.
Consumer strength remains the primary lever; any dip below trend could erode earnings by ~2.3pp.
A modest, hedged long exposure captures upside from potential inflation easing while limiting downside from severe stress events.
