Surety Bond vs Bank Guarantee: Why the Balance Is Shifting

15 August 2024

The Same Purpose, a Different Mechanism

Both a surety bond and a bank guarantee serve the same fundamental purpose: they provide the employer or project owner with financial protection if the contractor fails to perform. For contractors, the question is not whether they need one — it is which instrument to use, and why the answer is increasingly pointing toward surety.

The distinction comes down to how each instrument is structured, what it costs, and what it does to a contractor's balance sheet.

How Bank Guarantees Work

A bank guarantee is issued by the contractor's bank in favour of the employer. It is a direct commitment by the bank to pay the employer a specified amount if called upon. To issue the guarantee, the bank typically requires the contractor to provide collateral — cash, property, or other assets — or to use a portion of its non-cash credit facility.

The result is that a bank guarantee ties up capital. If a contractor has three active projects, each requiring a guarantee of 10% of the contract value, the combined drag on working capital can be substantial. In markets where interest rates are elevated, this cost is amplified.

How Surety Bonds Are Different

A surety bond is a three-party agreement: the contractor (the principal), the employer (the beneficiary), and the surety (the guarantor). The surety agrees to stand behind the contractor's performance, but the bond is not backed by collateral in the traditional banking sense. Instead, the surety underwrites the contractor's creditworthiness, track record, and financial standing.

Critically, a surety bond is typically classified as an off-balance-sheet instrument. It does not consume the contractor's banking credit lines. This means a contractor can take on a bonded project without reducing its capacity to borrow for other purposes — a significant advantage in a tighter credit environment.

The Shift in International Markets

In markets where bank guarantees have traditionally dominated — including Turkey, where 99% of construction bonds have historically been issued by banks — specialist surety providers are gaining ground, precisely because of the working capital advantages they offer.

Allianz Trade's bonding team in Turkey has noted the shift: surety bonds free up banking capacity, allowing contractors to increase their financing capability and meet short-term cash flow needs more efficiently. The same dynamic is playing out across emerging markets globally.

Accessing International Surety

For contractors in markets where the local surety infrastructure is underdeveloped, or where the employer requires a bond from an internationally recognised guarantor, the process of sourcing a surety bond can be complex. Solidum Global facilitates access to surety and guarantee solutions through a network of local and international partners — without the collateral requirements of the banking route and with a straightforward enquiry process.
