2025 Was an ‘Impressive Year’ for Manhattan Office Leasing: Colliers

Manhattan office leasing accelerated in 2025 with 41.92 million square feet leased for the year (up from 33.3 million in 2024) and 11.9 million leased in Q4 2025 versus 10.2 million in Q4 2024, marking the strongest single quarter since Q4 2019. Vacancy/availability tightened to 13.9% in Q4—the lowest in five years—with broad-based gains across submarkets (Midtown 19.32M sqft, Midtown South Q4 4.43M sqft, Lower Manhattan Q4 2.16M sqft), and several large renewals/expansions (Bloomberg ~496k, Moody’s ~460k, Millennium ~438k, NY AG ~378k, Ropes & Gray ~377k). The data indicate sustained post‑pandemic demand and tightening supply, supportive of Manhattan office valuations and favorable for landlords and CRE investors heading into 2026.

Analysis

Market structure: The 2025 surge (41.92M sqft vs 33.3M in 2024, ~+26%) and availability falling to 13.9% materially shifts bargaining power back to core Manhattan landlords and service providers. Winners: Colliers (CIGI) and high-quality Midtown owners (trophy REITs) who can cut concessions and push effective rents higher; losers: secondary/suburban offices, conversion candidates and highly leveraged landlords. Expect rent reversion in prime assets within 6–18 months and tightening mid-2026 net absorption versus 2019 baselines.

Risk assessment: Key tail risks are renewed hybrid/work-from-home adoption reducing demand (low-probability but high-impact), Fed-driven rate spikes that expand cap rates by +100–200bp in 3–9 months, and sudden supply additions (large blocks delivered 2026–2028). Immediate risk (days–weeks) is headline volatility around Fed statements; short-term (months) is Q1 leasing momentum; long-term (years) is structural office demand tied to finance/legal employment. Hidden dependencies include corporate hiring in finance/tech and lease rollover cliffs concentrated 2027–2029.

Trade implications: Direct plays: long CIGI (services fees up with transaction velocity) and selective NYC office REITs (SLG, ESRT) for 6–12 month recovery; pair trade long SLG vs short VNO to express quality spread compression. Options: buy 9–15 month call spreads 10–20% OTM on SLG/CIGI to limit downside, or sell 6–9 month OTM put spreads to collect premium if market-implied fear persists. Enter within 30–90 days to capture 2026 tailwinds, size 1.5–3% per idea, and reassess on Q1 leasing prints.

Contrarian angles: Consensus assumes broad office doom; miss is bifurcation — prime Manhattan should see outsized rent and value recovery while secondary stock lags. Reaction is likely underdone in high-quality names (price gap to fundamentals >20%) and overdone in heavily indebted landlords whose balance sheets mask potential upside. Historical parallel: post-crisis trophy office outperformed within 12–24 months while secondary lagged; unintended consequence is faster conversion slowdown as rents recover, preserving upside for landlords.

Key Decisions for Investors

• Establish a 2–3% portfolio long position in Colliers International (CIGI) within 30–60 days to capture higher transaction/agency fees from accelerating Manhattan leasing; target hold 6–12 months and trim if monthly leasing velocity drops >15% QoQ.
• Establish a 2–3% long position in SL Green Realty (SLG) or ESRT (select one based on valuation) to own trophy Manhattan cash flows; prefer entrants via 9–15 month call spreads 10–20% OTM to limit downside and realize upside if availability stays ≤14% into H2 2026.
• Implement a relative-value pair: long SLG (1.5% notional) / short Vornado (VNO) (1.5% notional) to express quality bifurcation; close if SLG outperforms VNO by >25% or if 10-year Treasury rises >125bp from current levels.
• Write 6–9 month put spreads on CIGI (collect premium) only if implied vol > historical vol+5ppt; monitor Colliers monthly Manhattan leasing reports and Fed rate decisions over next 90 days—reduce exposure if Q1 leasing falls >20% QoQ or the Fed signals persistent hikes.
