The Problem

The SME Cash Trap.

Lost Yield on a Massive Scale

UK SMEs are missing out on over £7.5bn of interest every year by leaving surplus cash in 0% current accounts and low-yield deposits.

Concentration Risk, Hidden in Plain Sight

A typical SME holding £1m with a single bank has over 85% of that balance above the FSCS limit of £120k – effectively uninsured if that bank fails.

Inertia and Friction Keep Cash Standing Still

Switching is rare. Time-poor business owners, complex onboarding and distrust of new platforms mean SMEs often “park” millions in accounts that are easy, but inefficient and underprotected.

Typical SME deposits ~£5k–£10k / yr
Preservoir-style T Bill strategy ~£20k+ / yr
Preservoir gives SMEs institutional-style access to UK government-backed instruments, helping them earn more, diversify away from single-bank risk, and still keep cash accessible.

The Solution

Democratising the
Money Markets.

Safety

Investments are 100% backed by the UK Government (Treasury Bills). Segregated custody at a 100+ year trusted institution.

Flexibility

Full liquidity. Sell down all or part of the holding whenever needed. No rigid lock-in periods.

Yield

Targeting ~4% gross return vs. typical low-yield bank deposits.

Why Now?

A Perfect
Macro Storm.

  • 01

    Interest Rates "Higher for Longer"

    The opportunity cost of idle cash is now a strategic P&L issue.

  • 02

    Post-Crisis Bank Distrust

    SMEs are actively seeking diversification away from commercial bank balance sheets (Post-SVB).

  • 03

    Tech Maturity

    Open Banking & APIs now allow for seamless onboarding.

  • 04

    End of the Status Quo

    Only 50% of business current accounts are opened with legacy 'big 4' banks.
